Class Vector_Object

java.lang.Object

org.jpedal.utils.repositories.Vector_Object

All Implemented Interfaces:

Serializable

public class Vector_Object
extends Object
implements Serializable

Provides the functionality/convenience of a Vector for objects -

Much faster because not synchronized and no cast - Does not double in size each time
