Class CollectionFactory<T>

java.lang.Object

edu.stanford.nlp.util.CollectionFactory<T>

All Implemented Interfaces:

java.io.Serializable

Direct Known Subclasses:

CollectionFactory.ArrayListFactory, CollectionFactory.HashSetFactory, CollectionFactory.LinkedListFactory, CollectionFactory.SizedArrayListFactory, CollectionFactory.TreeSetFactory

public abstract class CollectionFactory<T>
extends java.lang.Object
implements java.io.Serializable

Factory for vending Collections. It's a class instead of an interface because I guessed that it'd primarily be used for its inner classes.
