 package javax.faces.el;
 
 

MethodBinding is an object that can be used to call an arbitrary public method, on an instance that is acquired by evaluatng the leading portion of a method binding expression via a ValueBinding. An immutable MethodBinding for a particular method binding expression can be acquired by calling the createMethodBinding() method of the javax.faces.application.Application instance for this web application.

Deprecated:
This has been replaced by javax.el.MethodExpression.
 
 
 public abstract class MethodBinding {


    

Return the return value (if any) resulting from a call to the method identified by this method binding expression, passing it the specified parameters, relative to the specified javax.faces.context.FacesContext.

Parameters:
context javax.faces.context.FacesContext for the current request
params Array of parameters to be passed to the called method, or null for no parameters
Throws:
EvaluationException if an exception is thrown by the called method (the thrown exception must be included as the cause property of this exception)
MethodNotFoundException if no suitable method can be found
java.lang.NullPointerException if context is null
 
     public abstract Object invoke(FacesContext contextObject params[])
         throws EvaluationExceptionMethodNotFoundException;


    

Return the Java class representing the return type from the method identified by this method binding expression.

Parameters:
context javax.faces.context.FacesContext for the current request
Throws:
MethodNotFoundException if no suitable method can be found
java.lang.NullPointerException if context is null
 
     public abstract Class getType(FacesContext context)
         throws MethodNotFoundException;

    

Return the (possibly null) expression String, with leading and trailing delimiters, from which this MethodBinding was built. The default implementation returns null.

    public String getExpressionString() {
	return null;
    }
