public abstract class ValidatorELTag extends TagSupport
ValidatorELTag is a base class for all Jakarta Server Pages custom actions that create and register
Validator instance on the
EditableValueHolder associated with our most immediate surrounding
instance of a tag whose implementation class is a subclass of
UIComponentTag. To avoid creating duplicate
instances when a page is redisplayed, creation and registration of a
Validator occurs only
if the corresponding
UIComponent was created (by the owning
UIComponentTagBase) during the execution
of the current page.
This class must be used as a base class for tag instances that support specific
Subclasses of this class must implement the
createValidator() method, which creates and returns a
Validator instance. Any configuration properties that specify the limits to be enforced by this
Validator must have been set by the
createValidator() method. Generally, this occurs by copying
corresponding attribute values on the tag instance.
This tag creates no output to the page currently being created. It is used solely for the side effect of

Create a new instance of the specified
Validator class, and register it with the
associated with our most immediately surrounding
UIComponentTagBase instance, if the
instance was created by this execution of the containing Jakarta Server Pages page.
