Class CollectionWrapper<E>

java.lang.Object

net.cscott.jutil.CollectionWrapper<E>

All Implemented Interfaces:

Iterable<E>, Collection<E>

Direct Known Subclasses:

ListWrapper, SetWrapper

public abstract class CollectionWrapper<E>
extends Object
implements Collection<E>

CollectionWrapper is a class that acts as a wrapper around another Collection, using it as its backing store. This class isn't meant for direct usage, but rather provides for an easy way for developers to quickly add extra independent behavior to their own specific Collections without having to reimplement all of AbstractCollection's interface
