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 - when an I/O exception occurs
