javax.faces.el.MethodBinding.invoke()

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 {@link FacesContext}.
@param context {@link FacesContext} for the current request @param params Array of parameters to be passed to the called method,or null for no parameters @throws EvaluationException if an exception is thrownby the called method (the thrown exception must be included as the cause property of this exception) @throws MethodNotFoundException if no suitable method can be found @throws NullPointerException if contextis null
