Class TypeSet

java.lang.Object
net.okapia.osid.torrefacto.collect.TypeSet
All Implemented Interfaces:
Iterable<Type>, Types
Direct Known Subclasses:
TypeEnumSet
public class TypeSet extends Object implements Types
A Types collection that holds each type at most once. A type is uniquely identified by its namespace, authority, and identifier, so adding one that is already present is a no-op and a single remove drops it. Insertion order is preserved. This utility helps a provider manage type support. When support may be registered and withdrawn from several sources, use the reference-counted TypeRefSet instead. The backing set is synchronized.
