Class ActionMethodNameResolver

java.lang.Object
  de.mindmatters.faces.spring.context.servlet.controller.ActionMethodNameResolver

All Implemented Interfaces:

MethodNameResolver

public final class ActionMethodNameResolver
extends java.lang.Object
implements MethodNameResolver

Simple implementation of MethodNameResolver that maps JSF Action outcomes to method names. This class is the default implementation used by the MultiActionEventController class.

This class invokes the MethodBinding from the ActionSource exposed from the current ActionEvent and maps the evaluated outcome to a method name.

Examples:

• <h:commandButton action="foo".../> evaluates to method name 'foo'
• <h:commandButton action="#{foo.bar}".../> invokes method bar on object foo and returns an outcome (a String) which will be used as method name
