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

ipworksedi.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.

When this setting is True the XML generated may look like:

<BGM type="Segment">
<C002 type="Composite" desc="DOCUMENT/MESSAGE NAME">
<_1001 desc="Document/message name, coded">380</_1001>
<_1131 desc="Code list qualifier"></_1131>

</C002>

Where the elements "_1001", "C002", etc. are taken from the Id values of the EDI elements in the schema files.

Note: In order to produce valid XML, elements that would begin with a digit are prefixed with the "_" character.

In contrast if False (default) the XML generated may look like:

The renaming rule defines how EDI elements are renamed when translating to XML or JSON. The format is:

ediname:xmlanme

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:

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

• SetInputStream
• InputFile
• InputData

• SetOutputStream

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.

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.

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:
