Class TypeCheckingList

java.lang.Object

net.didion.jwnl.util.TypeCheckingList

All Implemented Interfaces:

Cloneable, Iterable, Collection, List, DeepCloneable

Direct Known Subclasses:

PointerTargetNodeList, RelationshipList

public class TypeCheckingList
extends Object
implements List, DeepCloneable

Wrapper for a list that checks the type of arguments before putting them in the list. It also does type-checking on methods which iterate over the list so that they fail fast if the argument is not of the correct type.
