InternalBindingKey

public class InternalBindingKey extends Object implements Serializable
Class InternalBindingKey implements the necessary wrapper code around the org.omg.CosNaming::NameComponent class to implement the proper equals() method and the hashCode() method for use in a hash table. It computes the hashCode once and stores it, and also precomputes the lengths of the id and kind strings for faster comparison.

Fields Summary
