Method Details
-
getTagHandlerDelegate
Return the implementation specific delegate instance that provides the bulk of the work for this handler instance.
- Specified by:
getTagHandlerDelegate
in classDelegatingMetaTagHandler
-
getValidatorId
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 thisEditableValueHolder
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
Return the
TagConfig
subclass used to configure this handler instance.
