Properties   Methods   Events   Config Settings   Errors  

The TRADACOMSTranslator component is optimized for TRADACOMS translation, providing a simple way to convert TRADACOMS documents to and from XML or JSON.

Syntax

TeditranslatorTRADACOMSTranslator

Remarks

The component provides a way to convert TRADACOMS to XML or JSON and vice versa.

Getting Started

The component 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 component 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:

• InputFile
• InputData

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

</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:

<BGM type="Segment">
<BGM01 type="Composite" desc="DOCUMENT/MESSAGE NAME">
<BGM0101 desc="Document/message name, coded">380</BGM0101>

</BGM01>

AddRenamingRule Method (TRADACOMSTranslator Component)

This method adds a renaming rule to define how an EDI element is renamed when translating to XML.

Syntax

procedure AddRenamingRule(Rule: String);

Remarks

This method adds a renaming rule. The rule defining how EDI elements are renamed when translating to XML. Renaming rules are optional.

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 (TRADACOMSTranslator Component)

Sets or retrieves a configuration setting.

Syntax

function Config(ConfigurationString: String): String;

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.

DisplaySchemaInfo Method (TRADACOMSTranslator Component)

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

Syntax

function DisplaySchemaInfo(): String;

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:

ExportXMLSchema Method (TRADACOMSTranslator Component)

Exports a XML schema.

Syntax

procedure ExportXMLSchema(SchemaFile: String);

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 component and later converted to EDI by the component.

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

GenerateAck Method (TRADACOMSTranslator Component)

Generates an EDI acknowledgement.

Syntax

function GenerateAck(): String;

Remarks

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

LoadRenamingRules Method (TRADACOMSTranslator Component)

Loads a set of renaming rules from file.

Syntax

procedure LoadRenamingRules(RuleFile: String);

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 (TRADACOMSTranslator Component)

Loads a schema file describing a Transaction Set.

Syntax

procedure LoadSchema(FileName: String);

Remarks

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

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

Reset Method (TRADACOMSTranslator Component)

Resets the state of the control.

Syntax

procedure Reset();

Remarks

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

SaveRenamingRules Method (TRADACOMSTranslator Component)

Saves the current renaming rule set to a file.

Syntax

procedure SaveRenamingRules(RuleFile: String);

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.

Translate Method (TRADACOMSTranslator Component)

Translates the specified data.

Syntax

procedure Translate();

Remarks

This method translates the specified data.

The component 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 component 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:

• InputFile
• InputData

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

EndFunctionalGroup Event (TRADACOMSTranslator Component)

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

Syntax

type TEndFunctionalGroupEvent = procedure (
  Sender: TObject;
  const Tag: String;
  const ControlNumber: String;
  Count: Integer;
  const FullSegment: String
) of Object;

property OnEndFunctionalGroup: TEndFunctionalGroupEvent read FOnEndFunctionalGroup write FOnEndFunctionalGroup;

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.

EndInterchange Event (TRADACOMSTranslator Component)

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

Syntax

type TEndInterchangeEvent = procedure (
  Sender: TObject;
  const Tag: String;
  const ControlNumber: String;
  const FullSegment: String
) of Object;

property OnEndInterchange: TEndInterchangeEvent read FOnEndInterchange write FOnEndInterchange;

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 (TRADACOMSTranslator Component)

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

Syntax

type TEndLoopEvent = procedure (
  Sender: TObject
) of Object;

property OnEndLoop: TEndLoopEvent read FOnEndLoop write FOnEndLoop;

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 (TRADACOMSTranslator Component)

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

Syntax

type TEndTransactionEvent = procedure (
  Sender: TObject;
  const Tag: String;
  const ControlNumber: String;
  Count: Integer;
  const FullSegment: String
) of Object;

property OnEndTransaction: TEndTransactionEvent read FOnEndTransaction write FOnEndTransaction;

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 (TRADACOMSTranslator Component)

Fired when information is available about errors during data delivery.

Syntax

type TErrorEvent = procedure (
  Sender: TObject;
  ErrorCode: Integer;
  const Description: String
) of Object;

property OnError: TErrorEvent read FOnError write FOnError;

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the component raises 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 (TRADACOMSTranslator Component)

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

Syntax

type TResolveSchemaEvent = procedure (
  Sender: TObject;
  const TransactionCode: String;
  const StandardVersion: String
) of Object;

property OnResolveSchema: TResolveSchemaEvent read FOnResolveSchema write FOnResolveSchema;

Remarks

The ResolveSchema event will fire when a the component 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 component that can be used to parse the transaction.

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

Segment Event (TRADACOMSTranslator Component)

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

Syntax

type TSegmentEvent = procedure (
  Sender: TObject;
  const Tag: String;
  const Name: String;
  const LoopName: String;
  const FullSegment: String
) of Object;

property OnSegment: TSegmentEvent read FOnSegment write FOnSegment;

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 (TRADACOMSTranslator Component)

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

Syntax

type TStartFunctionalGroupEvent = procedure (
  Sender: TObject;
  const Tag: String;
  const ControlNumber: String;
  const FullSegment: String
) of Object;

property OnStartFunctionalGroup: TStartFunctionalGroupEvent read FOnStartFunctionalGroup write FOnStartFunctionalGroup;

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 (TRADACOMSTranslator Component)

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

Syntax

type TStartInterchangeEvent = procedure (
  Sender: TObject;
  const Tag: String;
  const ControlNumber: String;
  const FullSegment: String
) of Object;

property OnStartInterchange: TStartInterchangeEvent read FOnStartInterchange write FOnStartInterchange;

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 (TRADACOMSTranslator Component)

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

Syntax

type TStartLoopEvent = procedure (
  Sender: TObject;
  const Name: String
) of Object;

property OnStartLoop: TStartLoopEvent read FOnStartLoop write FOnStartLoop;

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 (TRADACOMSTranslator Component)

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

Syntax

type TStartTransactionEvent = procedure (
  Sender: TObject;
  const Tag: String;
  const ControlNumber: String;
  const Code: String;
  const FullSegment: String
) of Object;

property OnStartTransaction: TStartTransactionEvent read FOnStartTransaction write FOnStartTransaction;

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 (TRADACOMSTranslator Component)

Fires whenever a validation warning is encountered.

Syntax

type TWarningEvent = procedure (
  Sender: TObject;
  WarnCode: Integer;
  const Message: String;
  SegmentNumber: Integer;
  const SegmentTag: String;
  const TechnicalErrorCode: String;
  const SegmentErrorCode: String;
  const ElementErrorCode: String;
  ElementPosition: Integer
) of Object;

property OnWarning: TWarningEvent read FOnWarning write FOnWarning;

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:
