EDIFACTValidator Component

Properties   Methods   Events   Config Settings   Errors  

The EDIFACTValidator component validates EDIFACT documents against the specified standard, ensuring compliance and correctness.

Syntax

TedEDIFACTValidator

Remarks

This component provides a simple way to validate an EDI document and obtain details about any validation errors.

Before calling Validate call LoadSchema to load the schema for the document to be validated. The schema defines many validation rules such as minimum and maximum lengths, minimum and maximum occurrences, and more. The validation performed by the component depends largely on the schema's definition.

When the Validate method is called the component will attempt to validate the document. If errors are found during validation the ValidationErrors property will be populated with details of each error.

Inspect the ValidationErrors property for information on any errors that were encountered.

Validation Example validator.InputFile = @"C:\EDIFACT_Files\INVOIC_InvalidRepeat.edi"; validator.LoadSchema(@"C:\EDIFACT_Schemas\D97A.xml", "INVOIC"); validator.Validate(); foreach (EDIFACTValidationErrorDetail error in validator.ValidationErrors) { Console.WriteLine(error.ErrorCode + ": " + error.ErrorMessage); }

The following is a list of config settings for the component with short descriptions. Click on the links for further details.

Delimiters Property (EDIFACTValidator Component)

Contains the delimiters for the EDI Document.

Syntax

property Delimiters: TedEDIFACTDelimiters read get_Delimiters;

Remarks

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

InputData Property (EDIFACTValidator Component)

The EDI message, specified as a string.

Syntax

property InputData: String read get_InputData write set_InputData;

Default Value

''

Remarks

Set this property to specify the input EDI message as a string. The message can then be parsed with Parse.

This property is not available at design time.

InputFile Property (EDIFACTValidator Component)

The file containing the EDI message.

Syntax

property InputFile: String read get_InputFile write set_InputFile;

Default Value

''

Remarks

Set this property to specify a file to read the input EDI message from. The message can then be parsed with Parse.

This property is not available at design time.

ValidationErrors Property (EDIFACTValidator Component)

Collection of validation errors for the current document.

Syntax

property ValidationErrors: TedEDIFACTValidationErrorDetailList read get_ValidationErrors;

Remarks

After calling Validate this property contains details of any validation errors. Validation errors are also accessible through the ValidateWarning event as the document is validated.

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

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

Config Method (EDIFACTValidator 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.

LoadSchema Method (EDIFACTValidator Component)

Loads schema information from a file or string data.

Syntax

procedure LoadSchema(fileOrData: String; messageName: String);

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 (EDIFACTValidator Component)

Resets all properties to their default values.

Syntax

procedure Reset();

Remarks

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

Validate Method (EDIFACTValidator Component)

Validate the EDI document and warn about any errors encountered.

Syntax

procedure Validate();

Remarks

This method parses the input EDI document, firing the ValidateWarning event for any non-blocking errors it encounters.

Error Event (EDIFACTValidator Component)

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

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.

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.

ResolveSchema Event (EDIFACTValidator Component)

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

Syntax

type TResolveSchemaEvent = procedure (
  Sender: TObject;
  const MessageVersion: String;
  const MessageType: String
) of Object;

property OnResolveSchema: TResolveSchemaEvent read FOnResolveSchema write FOnResolveSchema;

Remarks

This method fires when the component 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 LoadSchema.

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

MessageType - The type of message, such as INVOIC.

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

ValidateWarning Event (EDIFACTValidator Component)

Fires to warn about validation errors.

Syntax

type TValidateWarningEvent = procedure (
  Sender: TObject;
  Position: Int64;
  Line: Integer;
  Column: Integer;
  const ErrorCode: String;
  const ErrorMessage: String;
  ErrorType: Integer
) of Object;

property OnValidateWarning: TValidateWarningEvent read FOnValidateWarning write FOnValidateWarning;

Remarks

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

Config Settings (EDIFACTValidator Component)
