All Implemented Interfaces:
AttachedObjectHandler, EditableValueHolderAttachedObjectHandler, FaceletHandler, ValueHolderAttachedObjectHandler

public class ValidatorHandler
extends FaceletsAttachedObjectHandler
implements EditableValueHolderAttachedObjectHandler

Handles setting a Validator instance on an EditableValueHolder parent. Will wire all attributes set to the Validator instance created/fetched. Uses the "binding" attribute for grabbing instances to apply attributes to.

Will only set/create Validator is the passed UIComponent's parent is null, signifying that it wasn't restored from an existing tree.

Constructor Detail

ValidatorHandler

public ValidatorHandler(ValidatorConfig config)

Construct this instance around the configuration information in argument config

Parameters:
config - the TagConfig subclass for this kind of attached object.
Method Detail

getTagHandlerDelegate

protected TagHandlerDelegate getTagHandlerDelegate()

Return the implementation specific delegate instance that provides the bulk of the work for this handler instance.

Specified by:
getTagHandlerDelegate in class DelegatingMetaTagHandler

getValidatorId

public String getValidatorId(FaceletContext ctx)

Retrieve the id of the validator that is to be created and added to the parent EditableValueHolder. All subclasses should override this method because it is important for Facelets to have a unique way of identifying the validators that are added to this EditableValueHolder and allows exclusions to work properly. An exclusion is a validator declaration that has the attribute "disabled" which resolves to false, instructing Facelets not to register a default validator with the same id.


getValidatorConfig

public ValidatorConfig getValidatorConfig()

Return the TagConfig subclass used to configure this handler instance.
