Class Reflect


public class Reflect
extends java.lang.Object

Provides simply, convenient methods to invoke methods by name. This class is used to consolidate reflection needed to access methods specific to Sun's JVM or to remain backward compatible while supporting method in newer JVMs.

Most methods of this class invoke the first method on the specified object that matches the name and number of parameters. The type of the parameters are not considered, so do not attempt to use this class to invoke overloaded methods.

Instances of this class are not synchronized.
