InternalBindingKey

public class InternalBindingKey extends Object
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
public org.omg.CosNaming.NameComponent
name
private int
idLen
private int
kindLen
private int
hashVal
Constructors Summary
public InternalBindingKey()

public InternalBindingKey(org.omg.CosNaming.NameComponent n)
        idLen = 0;
        kindLen = 0;
	setup(n);
