VDATranslator Class

Properties   Methods   Events   Config Settings   Errors  

The VDATranslator class is optimized for VDA translation, providing a simple way to convert VDA documents to and from XML or JSON.

Syntax

ipworkseditranslator.Vdatranslator

Remarks

The class provides a way to convert VDA to XML or JSON and vice versa.

Getting Started

The class will convert a document from the format specified by InputFormat to the format specified by OutputFormat. In practice this allows for converting to XML or JSON from EDI and vice versa.

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

EDI elements may optionally be renamed when creating XML. To define how an element is renamed add a renaming rule by calling AddRenamingRule.

After calling Translate the resulting output will contain the EDI, XML or JSON data as defined by OutputFormat. If the output data is XML the ExportXMLSchema method may be called to export a schema (.xsd) defining the structure of a valid XML document. XML documents which adhere to this document may be translated from XML to EDI.

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:

• SetInputStream
• InputFile
• InputData

• SetOutputStream
• OutputFile
• OutputData: The output data is written to this property if no other destination is specified.

Note: Renaming rules are not required when converting from XML or JSON to EDI.

Config Method (Vdatranslator Class)

Sets or retrieves a configuration setting.

Syntax

public String config(String configurationString);

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.

DisplaySchemaInfo Method (Vdatranslator Class)

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

Syntax

public String displaySchemaInfo();

Remarks

After calling LoadSchema 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 LoadSchema.

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

Remarks

This method exports a XML schema describing the valid format of the XML document.

After translating a document from EDI to XML, this method may be called to export a schema (.xsd) describing the structure of a valid XML documents. XML documents which adhere to this document may be translated from XML to EDI.

This method is helpful if XML will be generated outside of the class and later converted to EDI by the class.

The SchemaFile parameter specifies the absolute or relative path to the file on disk.

GenerateAck Method (Vdatranslator Class)

Generates an EDI acknowledgement.

Syntax

public String generateAck();

Remarks

This functionality is not yet implemented and is reserved for future use.

LoadRenamingRules Method (Vdatranslator Class)

Loads a set of renaming rules from file.

Syntax

public void loadRenamingRules(String ruleFile);

Remarks

This method loads a set of renaming rules from a file on disk. The RenamingRuleCount will reflect the number of rules that were loaded. When loading a rule file all previously loaded rules will be replaced.

The RuleFile parameter specifies the absolute or relative path to the file on disk.

LoadSchema Method (Vdatranslator Class)

Loads a schema file describing a Transaction Set.

Syntax

public void loadSchema(String fileName);

Remarks

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

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

LoadSchemaStream Method (Vdatranslator Class)

Loads a schema stream describing a Transaction Set.

Syntax

public void loadSchemaStream(java.io.InputStream schemaStream);

Remarks

Parses Stream and loads it into an internal schema list. The SchemaFormat property must be set before calling this method.

The following SchemaFormat values are supported when calling this method:

• schemaBinary
• schemaBizTalk
• schemaSEF

Reset Method (Vdatranslator Class)

Resets the state of the control.

Syntax

public void reset();

Remarks

Reset resets the state of the class. All properties will be set to their default values.

SaveRenamingRules Method (Vdatranslator Class)

Saves the current renaming rule set to a file.

Syntax

public void saveRenamingRules(String ruleFile);

Remarks

This method saves the current renaming rule set specified by RenamingRule, RenamingRuleIndex, and RenamingRuleCount to a file on disk. These rules may be reloaded at a later time by calling LoadRenamingRules.

The RuleFile parameter specifies the absolute or relative path to the file on disk.

SetInputStream Method (Vdatranslator Class)

The stream to which the class will read the data to translate.

Syntax

public void setInputStream(java.io.InputStream inputStream);

Remarks

This method sets the stream from which the class will read the data to translate.

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:

• SetInputStream
• InputFile
• InputData

• SetOutputStream
• OutputFile
• OutputData: The output data is written to this property if no other destination is specified.

By default a stream will be closed after the called method returns. To leave a stream open for further processing set CloseStreamAfterTranslate to false.

SetOutputStream Method (Vdatranslator Class)

The stream to which the class will write the translated data.

Syntax

public void setOutputStream(java.io.OutputStream outputStream);

Remarks

This method sets the stream to which the class will write the translated data.

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:

• SetInputStream
• InputFile
• InputData

• SetOutputStream
• OutputFile
• OutputData: The output data is written to this property if no other destination is specified.

By default a stream will be closed after the called method returns. To leave a stream open for further processing set CloseStreamAfterTranslate to false.

Translate Method (Vdatranslator Class)

Translates the specified data.

Syntax

public void translate();

Remarks

This method translates the specified data.

The class will convert a document from the format specified by InputFormat to the format specified by OutputFormat. In practice this allows for converting to XML or JSON from EDI and vice versa.

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

EDI elements may optionally be renamed when creating XML. To define how an element is renamed add a renaming rule by calling AddRenamingRule.

After calling Translate the resulting output will contain the EDI, XML or JSON data as defined by OutputFormat. If the output data is XML the ExportXMLSchema method may be called to export a schema (.xsd) defining the structure of a valid XML document. XML documents which adhere to this document may be translated from XML to EDI.

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:

• SetInputStream
• InputFile
• InputData

• SetOutputStream
• OutputFile
• OutputData: The output data is written to this property if no other destination is specified.

EndFunctionalGroup Event (Vdatranslator Class)

Fires whenever a control segment is read that marks the end of an interchange.

Syntax

public class DefaultVdatranslatorEventListener implements VdatranslatorEventListener {

  ...
}

public class VdatranslatorEndFunctionalGroupEvent {
  public String tag;
  public String controlNumber;
  public int count;
  public String fullSegment;
}

Remarks

The EndFunctionalGroup event will fire when a control segment marking the end of a functional group is read. The Tag parameter contains the tag of the segment, such as GE. ControlNumber contains the control number associated with the segment, and links this event with the corresponding StartFunctionalGroup event. Count contains the value of the count element included in the closing segment, which identifies the number of transactions in a functional group.

public class DefaultVdatranslatorEventListener implements VdatranslatorEventListener {
  ...
  public void endInterchange(VdatranslatorEndInterchangeEvent e) {}
  ...
}

public class VdatranslatorEndInterchangeEvent {
  public String tag;
  public String controlNumber;
  public String fullSegment;
}

Remarks

The EndInterchange event will fire when a control segment marking the end of an interchange is read. The Tag parameter contains the tag of the segment, such as IEA. ControlNumber contains the control number associated with the segment, and links this event with the corresponding StartInterchange event.

EndLoop Event (Vdatranslator Class)

Fires when the end of a loop is detected in a transaction set.

Syntax

public class DefaultVdatranslatorEventListener implements VdatranslatorEventListener {
  ...
  public void endLoop(VdatranslatorEndLoopEvent e) {}
  ...
}

public class VdatranslatorEndLoopEvent {
}

Remarks

The EndLoop event will fire after the last segment in a loop is read. Each EndLoop event is paired with one StartLoop event.

EndTransaction Event (Vdatranslator Class)

Fires whenever a control segment is read that marks the end of a transaction.

Syntax

public class DefaultVdatranslatorEventListener implements VdatranslatorEventListener {
  ...
  public void endTransaction(VdatranslatorEndTransactionEvent e) {}
  ...
}

public class VdatranslatorEndTransactionEvent {
  public String tag;
  public String controlNumber;
  public int count;
  public String fullSegment;
}

Remarks

The EndTransaction event will fire when a control segment marking the end of a transaction is read. The Tag parameter contains the tag of the segment, such as SE. ControlNumber contains the control number associated with the segment, and links this event with the corresponding StartTransaction event. Count contains the value of the count element included in the closing segment, which identifies the number of segments in a transaction set.

Error Event (Vdatranslator Class)

Fired when information is available about errors during data delivery.

Syntax

public class DefaultVdatranslatorEventListener implements VdatranslatorEventListener {
  ...
  public void error(VdatranslatorErrorEvent e) {}
  ...
}

public class VdatranslatorErrorEvent {
  public int errorCode;
  public String description;
}

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the class throws an exception.

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

ResolveSchema Event (Vdatranslator Class)

Fires whenever a new transaction set is encountered and no schema is found for it.

Syntax

public class DefaultVdatranslatorEventListener implements VdatranslatorEventListener {
  ...
  public void resolveSchema(VdatranslatorResolveSchemaEvent e) {}
  ...
}

public class VdatranslatorResolveSchemaEvent {
  public String transactionCode;
  public String standardVersion;
}

Remarks

The ResolveSchema event will fire when a the class encounters the header segment of a new transaction set, but it finds no schema corresponding to it already loaded.

TransactionCode contains the code of the transaction, such as "810" or "APERAK".

StandardVersion contains the version of the transaction, such as "004010" or "D95A".

When processing this event, the caller can use LoadSchema() to load a new schema into the class that can be used to parse the transaction.

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

Segment Event (Vdatranslator Class)

Fires whenever a data segment in a transaction set is read.

Syntax

public class DefaultVdatranslatorEventListener implements VdatranslatorEventListener {
  ...
  public void segment(VdatranslatorSegmentEvent e) {}
  ...
}

public class VdatranslatorSegmentEvent {
  public String tag;
  public String name;
  public String loopName;
  public String fullSegment;
}

Remarks

The Segment event will fire when a data segment is read. The Tag parameter contains the tag of the segment. Name contains the name of the segment as defined in the associated transaction set schema. LoopName contains the name of the loop or group this segment is present in (such as N1Loop1).

StartFunctionalGroup Event (Vdatranslator Class)

Fires whenever a control segment is read that marks the start of a functional group.

Syntax

public class DefaultVdatranslatorEventListener implements VdatranslatorEventListener {
  ...
  public void startFunctionalGroup(VdatranslatorStartFunctionalGroupEvent e) {}
  ...
}

public class VdatranslatorStartFunctionalGroupEvent {
  public String tag;
  public String controlNumber;
  public String fullSegment;
}

Remarks

The StartFunctionalGroup event will fire when a control segment marking the start of a functional group structure is read. The Tag parameter contains the tag of the segment, such as GS. ControlNumber contains the control number associated with the segment.

StartInterchange Event (Vdatranslator Class)

Fires whenever a control segment is read that marks the start of an interchange.

Syntax

public class DefaultVdatranslatorEventListener implements VdatranslatorEventListener {
  ...
  public void startInterchange(VdatranslatorStartInterchangeEvent e) {}
  ...
}

public class VdatranslatorStartInterchangeEvent {
  public String tag;
  public String controlNumber;
  public String fullSegment;
}

Remarks

The StartInterchange event will fire when a control segment marking the start of an interchange structure is read. The Tag parameter contains the tag of the segment, such as ISA. ControlNumber contains the control number associated with the segment.

StartLoop Event (Vdatranslator Class)

Fires when the starting of a loop is detected in a transaction set.

Syntax

public class DefaultVdatranslatorEventListener implements VdatranslatorEventListener {
  ...
  public void startLoop(VdatranslatorStartLoopEvent e) {}
  ...
}

public class VdatranslatorStartLoopEvent {
  public String name;
}

Remarks

The StartLoop event will fire when the tag of a loop trigger segment is read. The Name parameter contains the schema-provided name of the loop, such as "N1Loop1".

StartTransaction Event (Vdatranslator Class)

Fires whenever a control segment is read that marks the start of a transaction.

Syntax

public class DefaultVdatranslatorEventListener implements VdatranslatorEventListener {
  ...
  public void startTransaction(VdatranslatorStartTransactionEvent e) {}
  ...
}

public class VdatranslatorStartTransactionEvent {
  public String tag;
  public String controlNumber;
  public String code;
  public String fullSegment;
}

Remarks

The StartTransaction event will fire when a control segment marking the start of a transaction is read. The Tag parameter contains the tag of the segment, such as ST. ControlNumber contains the control number associated with the segment. Code contains the transaction code (such as 810).

Warning Event (Vdatranslator Class)

Fires whenever a validation warning is encountered.

Syntax

public class DefaultVdatranslatorEventListener implements VdatranslatorEventListener {
  ...
  public void warning(VdatranslatorWarningEvent e) {}
  ...
}

public class VdatranslatorWarningEvent {
  public int warnCode;
  public String message;
  public int segmentNumber;
  public String segmentTag;
  public String technicalErrorCode;
  public String segmentErrorCode;
  public String elementErrorCode;
  public int elementPosition;
}

Remarks

The Warning event will fire during parsing of a segment of an EDI 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.

SegmentTag holds the tag name of the segment. SegmentErrorCode holds the error code that may be used in the IK304 field of a 999. ElementErrorCode holds the error code that may be used in the IK403 field of a 999. ElementPosition is the position of the element where the error occurred.

It's very important to note that segment validation happens right in the middle of the parsing process. Because of this, the Warning event will usually fire long before the validated segment becomes the current segment for the parser state. This means you cannot access the parser properties to examine the current segment in relation with the Warning event when the event fires.

Possible WarnCode values are:

TechnicalErrorCode holds a technical error code that helps identify structural issues with the document. For instance when parsing an X12 document this will hold values that may be used for TA1 error codes. When parsing X12 documents the following codes are applicable:
