Examples of MethodFunction

org.apache.commons.jxpath.functions.MethodFunction
An XPath extension function implemented as an individual Java method. @author Dmitri Plotnikov @version $Revision: 1.9 $ $Date: 2003/03/11 00:59:17 $
org.zkoss.xel.util.MethodFunction
A XEL function based on java.lang.reflect.Method. It is used by implementation of {@link org.zkoss.xel.ExpressionFactory}The user of XEL expressions rarely need it. @author tomyeh @since 3.0.0
