Object that the method returns

invokeEL

public static java.lang.Object invokeEL(java.lang.String el,
                                        java.lang.Class[] paramTypes,
                                        java.lang.Object[] params)

Parameters:

el - EL of the method to invoke

paramTypes - Array of Class defining the types of the parameters

params - Array of Object defining the values of the parameters

Returns:

Object that the method returns

setEL

public static void setEL(java.lang.String el,
                         java.lang.Object val)
