EDIFACTTranslator Class

Properties   Methods   Events   Config Settings   Errors  

The EDIFACTTranslator class converts EDIFACT data to XML and back, streamlining translation between formats.

Syntax

class edisdk.EDIFACTTranslator

Remarks

The class will convert a document from the format specified by input_format to the format specified by output_format. This allows for converting to XML from EDI and vice versa.

Before translating from EDI to XML it is recommended to load a schema using the load_schema method. This ensures additional information can be included in the XML or JSON document. If a schema is specified the XML will include types and descriptions as element attributes which are useful for interpreting the data.

After calling translate the resulting output will contain the EDI or XML data as defined by output_format.

Input and Output Properties

The class will determine the source and destination of the input and output based on which properties are set.

The order in which the input properties are checked is as follows:

• input_file
• input_data

When a valid source is found the search stops. The order in which the output properties are checked is as follows:

• output_file
• output_data: The output data is written to this property if no other destination is specified.

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.

load_schema method

Loads schema information from a file or string data.

Syntax

def load_schema(file_or_data: str, message_name: str) -> None: ...

Remarks

This method loads schema information for use when parsing, validating, and translating messages.

The FileOrData parameter can be set to the path of a file containing schema data, or can be set to the contents of a schema file directly.

MessageName can be set to the name of a specific message to load only the specified message's schema information. If left empty or set to "*", the entire schema will be loaded.

reset method

Resets all properties to their default values.

Syntax

def reset() -> None: ...

Remarks

This method resets all properties of the component to their default values as specified in the property definitions.

translate method

Translates the specified data.

Syntax

def translate() -> None: ...

Remarks

This method translates the specified data.

on_error event

Fires when an error occurs during message processing. Normally, the class fails with an error.

Syntax

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

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

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

Remarks

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

ConnectionId is the associated client Id, 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_resolve_schema event

Fires whenever a new EDIFACT message is encountered and no schema is found for it.

Syntax

class EDIFACTTranslatorResolveSchemaEventParams(object):
  @property
  def message_version() -> str: ...

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

# In class EDIFACTTranslator:
@property
def on_resolve_schema() -> Callable[[EDIFACTTranslatorResolveSchemaEventParams], None]: ...
@on_resolve_schema.setter
def on_resolve_schema(event_hook: Callable[[EDIFACTTranslatorResolveSchemaEventParams], None]) -> None: ...

Remarks

This method fires when the class encounters an EDIFACT message it has not loaded a schema for. The parameters of the event can be used to locate the correct schema and load it with load_schema.

MessageVersion - The EDIFACT version of the message, such as D97A.

MessageType - The type of message, such as INVOIC.

After the event fires, if the class still doesn't have a matching schema, then it will attempt schema-less parsing of the EDIFACT message.

on_validate_warning event

Fires to warn about validation errors.

Syntax

class EDIFACTTranslatorValidateWarningEventParams(object):
  @property
  def position() -> int: ...

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

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

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

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

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

# In class EDIFACTTranslator:
@property
def on_validate_warning() -> Callable[[EDIFACTTranslatorValidateWarningEventParams], None]: ...
@on_validate_warning.setter
def on_validate_warning(event_hook: Callable[[EDIFACTTranslatorValidateWarningEventParams], None]) -> None: ...

Remarks

When the class encounters a non-blocking error while validating a document, this event fires with information about the error.

EDIFACTTranslator 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.
