Class Summary
Class	Description
AbstractSerializableSetDecorator	Serializable subclass of AbstractSetDecorator.
AbstractSetDecorator	Decorates another `Set` to provide additional behaviour.
AbstractSortedSetDecorator	Decorates another `SortedSet` to provide additional behaviour.
CompositeSet	Decorates a set of other sets to provide a single unified view.
ListOrderedSet	Decorates another `Set` to ensure that the order of addition is retained and used by the iterator.
MapBackedSet	Decorates a `Map` to obtain `Set` behaviour.
PredicatedSet	Decorates another `Set` to validate that all additions match a specified predicate.
PredicatedSortedSet	Decorates another `SortedSet` to validate that all additions match a specified predicate.
SynchronizedSet	Decorates another `Set` to synchronize its behaviour for a multi-threaded environment.
SynchronizedSortedSet	Decorates another `SortedSet` to synchronize its behaviour for a multi-threaded environment.
TransformedSet	Decorates another `Set` to transform objects that are added.
TransformedSortedSet	Decorates another `SortedSet` to transform objects that are added.
TypedSet	Decorates another `Set` to validate that elements added are of a specific type.
TypedSortedSet	Decorates another `SortedSet` to validate that elements added are of a specific type.
UnmodifiableSet	Decorates another `Set` to ensure it can't be altered.
UnmodifiableSortedSet	Decorates another `SortedSet` to ensure it can't be altered.

Package org.apache.commons.collections.set Description

This package contains implementations of the Set and SortedSet interfaces.

The implementations are in the form of direct implementations and decorators. A decorator wraps another implementation of the interface to add some specific additional functionality.

The following implementations are provided in the package:

CompositeSet - a set that combines multiple sets into one

The following decorators are provided in the package:

Synchronized - synchronizes method access for multi-threaded environments
Unmodifiable - ensures the collection cannot be altered
Predicated - ensures that only elements that are valid according to a predicate can be added
Typed - ensures that only elements that are of a specific type can be added
Transformed - transforms each element added
ListOrdered - ensures that insertion order is retained
MapBackedSet - a set formed by decorating a Map
