Class HashcodePredicate

java.lang.Object
  wyvern.lib.predicates.HashcodePredicate

All Implemented Interfaces:

Predicate

public class HashcodePredicate

extends java.lang.Object

implements Predicate

Checks an object to see if it's got the right hashcode. A hashcode is an int value that uniquely identifies an object in the game. The hashcode is usually the ONLY way to be 100% sure that the object is the exact one you want, rather than just a lookalike.
