EDIFACTWriter Class

Properties   Methods   Events   Config Settings   Errors  

The EDIFACTWriter class is optimized for EDIFACT documents, providing a simple way to create EDIFACT documents.

Syntax

class ipworkseditranslator.EDIFACTWriter

Remarks

The class allows you to create a document from scratch. The class allows you to create an EDI document one segment at a time. Here's how a document would normally be created:

  1. Call load_schema to load the necessary schemas for the transactions that will be used.
  2. Specify where to write the output document by setting the output_file property or set_output_stream method, or set neither and check the output_data property.
  3. Create a new interchange start segment using the start_interchange_header method and set its properties using write_element_string and write_component_string.
  4. To write a basic element value to the current location, call the write_element_string method. For complex element values, there are two possibilities, elements which are split into components, and elements which repeat. To write these complex element values, use the start_element and end_element methods, with write_component_string and repeat_element methods for writing the values. (Examples available below).
  5. Create a new functional group using start_functional_group_header and set its properties using write_element_string and write_component_string.
  6. Create a new transaction using start_transaction_header and set the properties for the header segment.
  7. Write all the data for the transaction by creating new data segments using start_segment and providing the path of the segment to create using the schema names of the loops and segments, like /N1Loop1/N1.
  8. Once you are done with the segment, call end_segment.
  9. Once you are done with the transaction, call create_transaction_footer.
  10. Once you are done with the functional group, call create_functional_group_footer.
  11. Once the interchange is complete, call create_interchange_footer.

Example EDIFACTWriter Code:

EDIWriter1.StartInterchangeHeader("D98B"); //Complex Element, two components EDIWriter1.StartElement(); EDIWriter1.WriteComponentString("UNOB"); EDIWriter1.WriteComponentString("1"); EDIWriter1.EndElement(); //Skip a value for this element EDIWriter1.SkipElement(); //Basic element EDIWriter1.WriteElementString("7654323"); ... EDIWriter1.StartFunctionalGroupHeader(); ... EDIWriter1.StartTransactionHeader("APERAK"); //Complex Element, repeated element EDIWriter1.StartElement(); EDIWriter1.WriteComponentString("UNH1"); EDIWriter1.RepeatElement(); EDIWriter1.WriteComponentString("UNH2"); EDIWriter1.EndElement(); ... //Segment and its data EDIWriter1.StartSegment("BGM"); EDIWriter1.StartElement(); EDIWriter1.WriteComponentString("C00"); EDIWriter1.EndElement(); EDIWriter1.StartElement(); EDIWriter1.WriteComponentString("C10601"); EDIWriter1.EndElement(); EDIWriter1.EndSegment(); ... CreateTransactionFooter(); CreateFunctionalGroupFooter(); CreateInterchangeFooter();

file_write_mode Property

Controls how the output file is opened.

Syntax

def get_file_write_mode() -> int: ...
def set_file_write_mode(value: int) -> None: ...

file_write_mode = property(get_file_write_mode, set_file_write_mode)

Default Value

0

Remarks

This property controls how the component will open the output file specified in output_file. Possible values are:

fwmCreate (0)Always create a new file. If the file already exists, an error will be raised.
fwmOverwrite (1)If the output file already exists, it will be overwritten.
fwmAppend (2)If the output file already exists, data will be appended to it.

output_data Property

Contains the output data.

Syntax

def get_output_data() -> bytes: ...

output_data = property(get_output_data, None)

Default Value

""

Remarks

This property will be populated with the contents of the EDI data as output by the class when no output_file has been specified and set_output_stream has not been called with a valid output stream.

This property is read-only.

output_file Property

Specifies the name of the EDI file to write to.

Syntax

def get_output_file() -> str: ...
def set_output_file(value: str) -> None: ...

output_file = property(get_output_file, set_output_file)

Default Value

""

Remarks

Set output_file before calling the start_interchange_header method to write an EDI interchange to a file on disk.

schema_format Property

The format of the schema file.

Syntax

def get_schema_format() -> int: ...
def set_schema_format(value: int) -> None: ...

schema_format = property(get_schema_format, set_schema_format)

Default Value

0

Remarks

Set schema_format before calling the load_schema method to specify the loading schema format.

The following schema formats are supported:

0 (schemaAutomatic - default) The schema type is automatically determined based on file extension.
1 (schemaBinary) A binary schema that was previously compiled by calling compile_schema.
2 (schemaBizTalk) BizTalk (XSD): http://msdn.microsoft.com/en-us/library/aa559426(v=BTS.70).aspx
3 (schemaSEF) TIBCO Standard Exchange Format (SEF): https://docs.tibco.com/products/tibco-foresight-edisim-6-18-0
5 (schemaAltova) Altova: http://www.altova.com/
6 (schemaJSON - recommended) ArcESB JSON: https://arc.cdata.com/

suffix Property

What to append after each segment delimiter.

Syntax

def get_suffix() -> int: ...
def set_suffix(value: int) -> None: ...

suffix = property(get_suffix, set_suffix)

Default Value

0

Remarks

If suffix is different from suffixNone, trailing (suffix) characters are appended after each segment delimiter. This is useful if you want to have a carriage return/line feed after each segment to make the document more readable.

compile_schema Method

Compiles an existing XSD schema into an optimized binary representation.

Syntax

def compile_schema(xsd_schema: str, bin_schema: str) -> None: ...

Remarks

This method parses XsdSchema and generates an optimized binary representation that is saved into the path referenced by BinSchema. Binary schemas are smaller and require less resources when loading later using load_schema

If the schema file does not exists or cannot be parsed as an EDI schema, the component throws an exception.

config Method

Sets or retrieves a configuration setting.

Syntax

def config(configuration_string: str) -> str: ...

Remarks

config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

create_functional_group_footer Method

Closes the current functional group by writing its footer segment.

Syntax

def create_functional_group_footer() -> None: ...

Remarks

The create_functional_group_footer method will write any existing segments to the output stream and then generate and write the functional group closing segment (GE or UNE). If there is an open transaction set, create_functional_group_footer will first call create_transaction_footer to close it. If there is no functional group open, an exception will be thrown.

create_interchange_footer Method

Closes the current interchange by writing its footer segment.

Syntax

def create_interchange_footer() -> None: ...

Remarks

The create_interchange_footer method will write any existing segments to the output stream and then generate and write the interchange closing segment (IEA or UNZ). If there is an open transaction set, create_interchange_footer will first call create_transaction_footer to close it. If there is an open functional group, create_interchange_footer will first call create_functional_group_footer to close it. If there is no interchange open, an exception will be thrown.

create_transaction_footer Method

Closes the current transaction set by writing its footer segment.

Syntax

def create_transaction_footer() -> None: ...

Remarks

The create_transaction_footer method will write any existing segments to the output stream and then generate and write the transaction set closing segment (SE or UNT). If there are no open transaction sets, an exception will be thrown.

display_schema_info Method

Returns a string showing the structure of the schema defining the document.

Syntax

def display_schema_info() -> str: ...

Remarks

After calling load_schema this may be called to obtain information about the structure of the schema defining the document. If the desired xpath is not known this helps determine the structure so that the correct xpath can be built.

Note: A valid schema must be loaded via load_schema.

For instance: Console.WriteLine(component.DisplaySchemaInfo()); Will output text like:

end_element Method

Finishes the current composite data element.

Syntax

def end_element() -> None: ...

Remarks

Call end_element once you've written all components in an element started with start_element. You should not call this if you wrote a simple element using write_element_string

end_segment Method

Ends writing the current segment.

Syntax

def end_segment() -> None: ...

Remarks

end_segment terminates writing the current segment and flushes it to the output stream/file.

You should call end_segment to close a segment started with start_segment, start_interchange_header, start_functional_group_header or start_transaction_header.

flush Method

Forces any pending segments to be written to the output stream without closing it.

Syntax

def flush() -> None: ...

Remarks

The flush method forces the component to write the last created segment to the output stream and then flush the output stream.

load_schema Method

Loads a schema file describing a Transaction Set.

Syntax

def load_schema(file_name: str) -> None: ...

Remarks

This method parses the File and loads it into an internal schema list. The class will attempt to automatically detect the schema_format.

If the schema file does not exist or cannot be parsed as an EDI schema, the class fails with an error.

repeat_element Method

Adds a new repetition to the current element.

Syntax

def repeat_element() -> None: ...

Remarks

repeat_element is used to write repeated data elements in supporting version of X12 or EDIFACT. To use it, first write the first repetition of the simple or composite data element and then call repeat_element to repeat it, then write again.

Example: Repeating a simple data element: EDIWriter writer = new EDIWriter(); ... writer.StartSegment("Tag"); ... writer.WriteElementString("R1_1"); writer.RepeatElement(); writer.WriteElementString("R1_2"); writer.RepeatElement(); writer.WriteElementString("R1_3"); ... writer.EndSegment();

Example: Repeating a composite data element: EDIWriter writer = new EDIWriter(); ... writer.StartSegment("Tag"); ... writer.StartElement(); writer.WriteComponentString("C1_1"); writer.WriteComponentString("C2_1"); writer.RepeatElement(); writer.WriteComponentString("C1_2"); writer.WriteComponentString("C2_2"); writer.RepeatElement(); writer.WriteComponentString("C1_3"); writer.EndElement(); ... writer.EndSegment();

reset Method

Resets the state of the control.

Syntax

def reset() -> None: ...

Remarks

Resets the state of the writer. If a document has been partially written already, it will not be closed correctly and the write process will be aborted.

skip_component Method

Moves to the next sub-element in the current composite element in the current segment.

Syntax

def skip_component() -> None: ...

Remarks

skip_component can be used to avoid providing a value for the current sub-element in the opened composite element within the current segment.

If the sub-element already has a value (such as one provided by default by the class), said value will not be overwritten.

skip_element Method

Moves to the next data element in the current segment.

Syntax

def skip_element() -> None: ...

Remarks

skip_element can be used to avoid providing a value for the current element in the current segment.

If the element already has a value (such as one provided by default by the class), said value will not be overwritten.

start_element Method

Starts a new EDI composite data element on the current segment.

Syntax

def start_element() -> None: ...

Remarks

When called, a new composite data element is created in the current segment. You can then call write_component_string one or more times to write the individual components or subelements that make up this composite.

Call end_element once you've written all components in this element.

start_functional_group_header Method

Creates a new EDI functional group header segment on the current document.

Syntax

def start_functional_group_header() -> None: ...

Remarks

When called, a new functional group start (GS or UNG) segment is created and set as the current segment. You should then set the values on said segment before adding a new transaction set within the document.

start_interchange_header Method

Creates a new EDI Interchange header segment on the current document.

Syntax

def start_interchange_header(version: str) -> None: ...

Remarks

When called, a new interchange start (ISA or UNB) segment is created and set as the current segment. You should then set the values on said segment before creating a functional group or a new transaction set within the document.

start_segment Method

Creates a new EDI data segment on the current document.

Syntax

def start_segment(segment_type: str) -> None: ...

Remarks

When called, a new data segment is created in the current transaction and set as the current segment. You can then set the values on said segment. Creating a new data segment automatically writes the previous current segment to the output stream.

The SegmentType argument specifies the type of data segment to create, using an XPath-like syntax, based on the transaction set schema. For example, to create a new N1 segment on the first N1 loop, specify "/N1Loop1/N1".

It's important to realize that segments must be created in the same order they should appear on the target EDI document. The EDIWriter component doesn't automatically enforce ordering rules, nor does it force the document to reorder segments in loops automatically.

start_transaction_header Method

Creates a new EDI transaction set header on the current document.

Syntax

def start_transaction_header(code: str) -> None: ...

Remarks

When called, a new transaction set start (ST or UNH) segment is created and set as the current segment. You should then set the values on said segment before adding creating transaction data segments.

The Code argument should specify the transaction code you want to create (for example, "850" or "INVOIC"). This value, together with the EDI specification and the version provided in the start_interchange_header method are used to locate a matching transaction set schema on the components schema cache. You must make sure that a corresponding schema has been successfully loaded into the component by using the load_schema method before trying to call start_transaction_header.

write_component_string Method

Sets the value of the next class within the current element in the current segment.

Syntax

def write_component_string(value: str) -> None: ...

Remarks

Use the write_component_string method to specify a value for an individual component within a composite data element.

To write an entire composite data element, first call the start_element method, then do one or more calls to write_component_string. Finish the composite element by calling the end_element method.

write_element_string Method

Sets a value of the next element in the current segment to a simple value.

Syntax

def write_element_string(value: str) -> None: ...

Remarks

Use the write_element_string method to specify a value for the next data element with simple content on the current segment.

To write a composite data element, even if it has a single sub-element, use the start_element and write_component_string methods instead.

write_transaction Method

Writes an entire transaction to the output.

Syntax

def write_transaction(value: str) -> None: ...

Remarks

Use the write_transaction method when you have generated a complete transaction outside of the class and want to include it in the document being created by this instance.

No validation is done on the contents of the Value parameter. You must ensure the transaction data is valid and matches the same conventions (delimiters, etc) being used in this document.

on_error Event

Information about errors during data delivery.

Syntax

class EDIFACTWriterErrorEventParams(object):
  @property
  def error_code() -> int: ...

  @property
  def description() -> str: ...

# In class EDIFACTWriter:
@property
def on_error() -> Callable[[EDIFACTWriterErrorEventParams], None]: ...
@on_error.setter
def on_error(event_hook: Callable[[EDIFACTWriterErrorEventParams], None]) -> None: ...

Remarks

The on_error event is fired in case of exceptional conditions during message processing. Normally the class fails with an error.

ErrorCode contains an error code and Description contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

on_output Event

Fires whenever a segment is complete.

Syntax

class EDIFACTWriterOutputEventParams(object):
  @property
  def output_data() -> bytes: ...

# In class EDIFACTWriter:
@property
def on_output() -> Callable[[EDIFACTWriterOutputEventParams], None]: ...
@on_output.setter
def on_output(event_hook: Callable[[EDIFACTWriterOutputEventParams], None]) -> None: ...

Remarks

The on_output event will fire when the writer completes a new segment and writes data to the output stream or buffer. The Data parameter contains the data bytes.

on_warning Event

Fires whenever a validation warning is encountered.

Syntax

class EDIFACTWriterWarningEventParams(object):
  @property
  def warn_code() -> int: ...

  @property
  def message() -> str: ...

  @property
  def segment_number() -> int: ...

  @property
  def segment_tag() -> str: ...

  @property
  def segment_error_code() -> str: ...

  @property
  def element_error_code() -> str: ...

  @property
  def element_position() -> int: ...

# In class EDIFACTWriter:
@property
def on_warning() -> Callable[[EDIFACTWriterWarningEventParams], None]: ...
@on_warning.setter
def on_warning(event_hook: Callable[[EDIFACTWriterWarningEventParams], None]) -> None: ...

Remarks

The on_warning event will fire if a validation error is encountered when writing a new segment to the output document. The WarnCode parameter contains the type of warning encountered. Message is a textual description of the problem. SegmentNumber is the index of the segment where the problem was found.

0 The component is not required but is present.
1 Invalid segment count.

EDIFACTWriter Config Settings

The class accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the config method.

EDIFACTWriter Config Settings

ComponentDelimiter:   The delimiter character to use to separate components.

When set, this changes the default delimiter to use to separate components within a data element. The default value depends on the EDI specification being used.

EdifactSyntaxVersion:   Changes the syntax version used for EDIFACT control segments.

Can be a number from 1 to 4. The default value is 1.

EDIStandard:   The document format.

This property specifies standard that the document follows. Possible values are:

  • 1 (EDIFACT - default)
  • 3 (TRADACOMS)

ElementDelimiter:   The delimiter character to use to separate data elements.

When set, this changes the default delimiter to use to separate data elements within a segment. The default value depends on the EDI specification being used.

Encoding:   The character encoding to be applied when reading and writing data.

If the data contains non-ASCII characters this setting should be specified so characters are properly preserved. This value should be set to a valid character set such as "UTF-8" or "ISO-8859-1".

IncludeUNA:   Whether to include the UNA segment in the output.

This setting determines whether the UNA segment is included in the EDIFACT output. If False, no Service String Advice (UNA) segment will be generated for EDIFACT interchanges. The default value is True.

ReleaseChar:   The character to use to escape delimiters within values.

When set, this changes the default escape character. The default value depends on the EDI specification being used.

RepetitionChar:   The repetition character.

When set, this changes the default repetition character. The default value depends on the EDI specification being used.

SegmentDelimiter:   The delimiter character to use to separate segments.

When set, this changes the default delimiter to use to separate segments within an EDI document. The default value depends on the EDI specification being used.

StrictSchemaValidation:   Specifies the behavior during schema validation.

This setting specifies what happens when performing schema validation and a validation warning occurs. By default this value is set to 1 (Warn) and the on_warning event will fire, but processing will not stop. See the WarnCode parameter list in the on_warning event for details about possible validation warnings. Possible values for this setting are:

0 (Ignore) All validation warnings will be ignored. on_warning will not fire with warnings.
1 (Warn - default) The on_warning event will fire with all validation warnings.
2 (Error) All validation warnings are treated as errors and will cause an exception. Processing will stop immediately.

TransactionOnly:   Ignores interchange and functional group validation, allowing you to build the transaction body.

When set to true, interchange and functional group headers will not be required. This allows building of the transaction level of an EDIFact document without specifying a document type.

Base Config Settings

BuildInfo:   Information about the product's build.

When queried, this setting will return a string containing information about the product's build.

CodePage:   The system code page used for Unicode to Multibyte translations.

The default code page is Unicode UTF-8 (65001).

LicenseInfo:   Information about the current license.

When queried, this setting will return a string containing information about the license this instance of a class is using. It will return the following information:

  • Product: The product the license is for.
  • Product Key: The key the license was generated from.
  • License Source: Where the license was found (e.g., RuntimeLicense, License File).
  • License Type: The type of license installed (e.g., Royalty Free, Single Server).
  • Last Valid Build: The last valid build number for which the license will work.
ProcessIdleEvents:   Whether the class uses its internal event loop to process events when the main thread is idle.

If set to False, the class will not fire internal idle events. Set this to False to use the class in a background thread on Mac OS. By default, this setting is True.

SelectWaitMillis:   The length of time in milliseconds the class will wait when DoEvents is called if there are no events to process.

If there are no events to process when do_events is called, the class will wait for the amount of time specified here before returning. The default value is 20.

UseFIPSCompliantAPI:   Tells the class whether or not to use FIPS certified APIs.

When set to True, the class will utilize the underlying operating system's certified APIs. Java editions, regardless of OS, utilize Bouncy Castle FIPS, while all the other Windows editions make use of Microsoft security libraries.

FIPS mode can be enabled by setting the UseFIPSCompliantAPI configuration setting to True. This is a static setting which applies to all instances of all classes of the toolkit within the process. It is recommended to enable or disable this setting once before the component has been used to establish a connection. Enabling FIPS while an instance of the component is active and connected may result in unexpected behavior.

For more details please see the FIPS 140-2 Compliance article.

Note: This setting is only applicable on Windows.

UseInternalSecurityAPI:   Tells the class whether or not to use the system security libraries or an internal implementation.

By default the class will use the system security libraries to perform cryptographic functions where applicable. Setting this to True tells the class to use the internal implementation instead of using the system's security API.
