EDIFACTWriter Component

Properties   Methods   Events   Config Settings   Errors  

The EDIFACTWriter component generates EDIFACT documents with a clear, straightforward API.

Syntax

EDISDK.EDIFACTWriter

Remarks

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

1. Call LoadSchema to load the necessary schemas for the transactions that will be used.
2. Specify where to write the output document by setting the OutputFile, or check the OutputData property after writing.
3. Create a new interchange start segment by setting the fields of the Interchange property and call the StartInterchange method. Once the interchange is complete, call EndInterchange to add the interchange footer.
4. If you want to create a functional group, set the fields of the FunctionalGroup property and then call the StartFunctionalGroup. Once all the messages in the group have been created, call EndFunctionalGroup to add a footer for the group.
5. To start a message, call the StartMessage method. Once all segments have been added, call EndMessage to add a footer to the message.
6. To begin a segment, call the StartSegment method and pass in the tag for the segment. Once all the elements in the segment have been added, call EndSegment to add the segment terminator.
7. To write a basic element to the current segment, call the WriteElement method.
8. To write a composite element, call the StartCompositeElement method, then call the WriteComponent method for each component, and finally call EndCompositeElement to end the element.

Delimiters Property (EDIFACTWriter Component)

Contains the delimiters for the EDI Document..

Syntax

public EDIFACTDelimiters getDelimiters();

Remarks

This property contains the delimiters that will be used when writing the EDIFACT document. If the document uses delimiters other than the default, change the properties of this object to write the document correctly.

This property is read-only and not available at design time.

Please refer to the EDIFACTDelimiters type for a complete list of fields.

FileWriteMode Property (EDIFACTWriter Component)

Determines how the output file is opened for writing.

public void setFileWriteMode(int fileWriteMode);
Enumerated values:
  public final static int fwmCreate = 0;

  public final static int fwmOverwrite = 1;

  public final static int fwmAppend = 2;

Default Value

0

Remarks

When OutputFile is set, this property determines how the file will be opened.

This property is not available at design time.

FunctionalGroup Property (EDIFACTWriter Component)

Contains the current functional group information for the EDI Document.

Syntax

public EDIFACTFunctionalGroup getFunctionalGroup();

Remarks

The functional group information is used when writing the functional group header (GS) and trailer (GE) segments. The properties of this object must be changed before calling StartFunctionalGroup to write the functional group correctly.

Remarks

The interchange information is used when writing the interchange header (ISA) and trailer (IEA) segments. The properties of this object must be changed before calling StartInterchange to write the interchange correctly. After calling StartInterchange changing the properties of this object will change the values for the next interchange only.

This property is read-only and not available at design time.

Please refer to the EDIFACTInterchange type for a complete list of fields.

Message Property (EDIFACTWriter Component)

Contains the current message information for the EDI Document.

Syntax

public EDIFACTMessage getMessage();

Remarks

This property holds the current message information for the EDI document. It is used by the StartMessage method to create a new transaction set header. The properties of this object must be changed before calling StartMessage to write the transaction set correctly. After calling StartMessage changing the properties of this object will change the values for the next transaction set only.

This property is read-only and not available at design time.

The name of the output file to which the EDI data will be written.

Syntax

public String getOutputFile();

This property is not available at design time.

Close Method (EDIFACTWriter Component)

Closes the writer.

Syntax

public void close();

Remarks

Calling Close will close the writer and release any resources associated with it. After calling Close, the writer cannot be used unless it is re-initialized.

Config Method (EDIFACTWriter Component)

Sets or retrieves a configuration setting.

Syntax

public String config(String configurationString);

Remarks

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

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, 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.

EndCompositeElement Method (EDIFACTWriter Component)

Syntax

public void endCompositeElement();

Remarks

This method is used to close a CompositeElement. This method may only be called after a successful call to StartCompositeElement

EndFunctionalGroup Method (EDIFACTWriter Component)
