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

IOException
