org.omnifaces.taghandler.MethodParam

All Implemented Interfaces:

javax.faces.view.facelets.FaceletHandler

public class MethodParam
extends javax.faces.view.facelets.TagHandler

This handler wraps a value expression that's actually a method expression by another value expression that returns a method expression that gets the value of first value expression, which as "side-effect" executes the original method expression.

This somewhat over-the-top chain of wrapping is done so a method expression can be passed into a Facelet tag as parameter.
