X12Validator Class

Properties   Methods   Events   Config Settings   Errors  

The X12Validator class validates X12 documents against the specified standard, ensuring compliance and correctness.

Syntax

edisdk.X12Validator

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 class depends largely on the schema's definition.

When the Validate method is called the class 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:\X12_Files\810_InvalidRepeat.txt"; validator.LoadSchema(@"C:\X12_Schemas\4010.xml", "810"); validator.Validate(); foreach (X12ValidationErrorDetail error in validator.ValidationErrors) { Console.WriteLine(error.ErrorCode + ": " + error.ErrorMessage); }

Delimiters Property (X12Validator Class)

Contains the delimiters for the EDI Document.

Syntax

public X12Delimiters getDelimiters();

Remarks

This property contains the delimiters that will be used when parsing the X12 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 X12Delimiters type for a complete list of fields.

InputData Property (X12Validator Class)

The EDI message, specified as a string.

Syntax

public String getInputData();
public void setInputData(String 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 (X12Validator Class)

The file containing the EDI message.

Syntax

public String getInputFile();
public void setInputFile(String inputFile);

Default Value

""

Remarks

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

If the file is not found or cannot be opened, an error will be returned.

Note: If both InputFile and InputData are set, InputData takes precedence.

This property is not available at design time.

ValidationErrors Property (X12Validator Class)

Collection of validation errors for the current document.

Syntax

public X12ValidationErrorDetailList getValidationErrors();

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 X12ValidationErrorDetail type for a complete list of fields.

Config Method (X12Validator 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.

LoadSchema Method (X12Validator Class)

Loads schema information from a file or string data.

Syntax

public void loadSchema(String fileOrData, String messagename);

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 (X12Validator Class)

Resets all properties to their default values.

Syntax

public void reset();

Remarks

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

SetInputStream Method (X12Validator Class)

The stream containing the EDI data.

Syntax

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

Remarks

Call this method to specify a stream to read the input EDI data from. The data can then be parsed with Parse.

Validate Method (X12Validator Class)

Validate the EDI document and warn about any errors encountered.

Syntax

public void validate();

Remarks

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

Error Event (X12Validator Class)

Fires when a parsing error occurs.

Syntax

public class DefaultX12ValidatorEventListener implements X12ValidatorEventListener {
  ...
  public void error(X12ValidatorErrorEvent e) {}
  ...
}

public class X12ValidatorErrorEvent {
  public int errorCode;
  public String description;
}

Remarks

This event fires when the class encounters a parsing error while processing a document.

ResolveSchema Event (X12Validator Class)

Fires to request schema information for a specific transaction set.

Syntax

public class DefaultX12ValidatorEventListener implements X12ValidatorEventListener {
  ...
  public void resolveSchema(X12ValidatorResolveSchemaEvent e) {}
  ...
}

public class X12ValidatorResolveSchemaEvent {
  public String versionNumber;
  public String transactionSetIDCode;
}

Remarks

LoadSchema can be called from within this event to load the schema information for the specified transaction set.

ValidateWarning Event (X12Validator Class)

Fires to warn about validation errors.

Syntax

public class DefaultX12ValidatorEventListener implements X12ValidatorEventListener {
  ...
  public void validateWarning(X12ValidatorValidateWarningEvent e) {}
  ...
}

public class X12ValidatorValidateWarningEvent {
  public long position;
  public int line;
  public int column;
  public String errorCode;
  public String errorMessage;
  public int errorType;
}

Remarks

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