public abstract class CpoolEntry
extends java.lang.Object

An entry in the constant pool for a ClassType. Each entry belong to the constant pool table of the "owning" ClassType. Hashing is used to make each entry unique (with a ClassType). By convention, each sub-class has a static get_const method which is used when a contant pool entry is need: The get_const method will return an existing matching entry if possible, or allocate a new one if needed.
