Java Interface for Task-Level Validation

The definition of the JavaScript interface for task-level validation is as follows:

Syntax

public interface TaskValidator {
public class StringRef {
   public String reference = new String();
   public String toString(){return reference;}
public boolean validate(
   BLTHContext ctx,
   String attrValue,
   StringRef updatedValue,
   StringRef errorMessage
   ) throws AttributeValidationException;
}

Parameters

ctx

Input parameter

Specifies an object that contains methods for retrieving information in the current task session.

attrValue

Input parameter

Specifies the value of the attribute being validated.

updatedValue

Output parameter

Provides an optional transformation value that replaces the user-supplied value being validated. When no transformation is necessary, pass back null.

errorMessage

Output Parameter

If validation fails, it displays a message to the user.

Comments

For more information about Java validation rules and on managed objects, see the CA Identity Manager Javadoc.

Returns

• True—the implementation considers the value in attributeValue to be valid, or it passes back a transformed value in changedValue.
• False—the implementation considers attributeValue to be invalid.

Throws

AttributeValidationException
