javax.el.MethodExpression
An Expression that refers to a method on an object.
The {@link ExpressionFactory#createMethodExpression} methodcan be used to parse an expression string and return a concrete instance of MethodExpression that encapsulates the parsed expression. The {@link FunctionMapper} is used at parse time, not evaluation time, so one is not needed to evaluate an expression using this class. However, the {@link ELContext} is needed at evaluation time.
The {@link #getMethodInfo} and {@link #invoke} methods will evaluate the expression each time they are called. The {@link ELResolver} in the ELContext is used to resolve the top-level variables and to determine the behavior of the . and [] operators. For any of the two methods, the {@link ELResolver#getValue} method is used to resolve all properties up to but excluding the last one. This provides the base object on which the method appears. If the base object is null, a PropertyNotFoundException must be thrown. At the last resolution, the final property is then coerced to a String, which provides the name of the method to be found. A method matching the name and expected parameters provided at parse time is found and it is either queried or invoked (depending on the method called on this MethodExpression).

See the notes about comparison, serialization and immutability in the {@link Expression} javadocs. @see ELResolver @see Expression @see ExpressionFactory @since JSP 2.1

MethodExpression evaluates a method on the current bean context.

Represents a method expression in the expression tree

A method expression node is inserted in the expression tree for any valid OData method operator in {@link MethodOperator} (e.g. for "substringof", "concat", "year", ... )

            // It seems that MethodExpressionValueChangeListener from API contains support for it but there is one big
            // problem - one-arg constructor will not preserve the current VariableMapper.
            // This is a problem when using facelets and <ui:decorate/> with EL params (see MYFACES-2541 for details).
            // So we must create two MethodExpressions here - both are created from the current 
            // facelets context and thus variable mapping will work.
            final MethodExpression methodExpressionOneArg = attr.getMethodExpression(ctx, null, VALUECHANGE_SIG);
