Package org.apache.myfaces.view.facelets.tag.ui

Class LegacyDecorateHandler

java.lang.Object

jakarta.faces.view.facelets.TagHandler

org.apache.myfaces.view.facelets.tag.ui.LegacyDecorateHandler

All Implemented Interfaces:

FaceletHandler, TemplateClient

public final class LegacyDecorateHandler
extends TagHandler
implements TemplateClient

The decorate tag acts the same as a composition tag, but it will not trim everything outside of it. This is useful in cases where you have a list of items in a document, which you would like to be decorated or framed. The sum of it all is that you can take any element in the document and decorate it with some external logic as provided by the template. NOTE: This implementation is provided for compatibility reasons and it is considered faulty. It is enabled using org.apache.myfaces.STRICT_JSF_2_FACELETS_COMPATIBILITY web config param. Don't use it if EL expression caching is enabled.

Description copied from interface: TemplateClient

This contract is much like the normal FaceletHandler.apply method, but it takes in an optional String name which tells this instance what fragment/definition it's looking for. If you are a match, apply your logic to the passed UIComponent and return true, otherwise do nothing and return false.

Specified by:

apply in interface TemplateClient

Parameters:

ctx - the FaceletContext of your instance, not the templates'

parent - current UIComponent instance to be applied

name - the String name or null if the whole body should be included

Returns:

true if this client matched/applied the definition for the passed name

Throws:

IOException

FacesException

FaceletException

jakarta.el.ELException
