Class AbstractValidator

java.lang.Object
  com.ibm.xsp.complex.ValueBindingObjectImpl
      com.ibm.xsp.validator.AbstractValidator

All Implemented Interfaces:

ComponentBindingObject, ValueBindingObject, java.util.EventListener, javax.faces.component.StateHolder, javax.faces.validator.Validator

Direct Known Subclasses:

ConstraintValidator, DateTimeRangeValidator, ExpressionValidator, ModulusSelfCheckValidator, RequiredValidator

public abstract class AbstractValidator
extends ValueBindingObjectImpl
implements javax.faces.validator.Validator

Useful superclass for server-side validators. If client-side validation is also required, subclasses should implement ClientSideValidator.
