Class Summary
Class	Description
AbstractNavigableSetDecorator<E>	Decorates another `NavigableSet` to provide additional behaviour.
AbstractSerializableSetDecorator<E>	Serializable subclass of AbstractSetDecorator.
AbstractSetDecorator<E>	Decorates another `Set` to provide additional behaviour.
AbstractSortedSetDecorator<E>	Decorates another `SortedSet` to provide additional behaviour.
CompositeSet<E>	Decorates a set of other sets to provide a single unified view.
ListOrderedSet<E>	Decorates another `Set` to ensure that the order of addition is retained and used by the iterator.
MapBackedSet<E,V>	Decorates a `Map` to obtain `Set` behaviour.
PredicatedNavigableSet<E>	Decorates another `NavigableSet` to validate that all additions match a specified predicate.
PredicatedSet<E>	Decorates another `Set` to validate that all additions match a specified predicate.
PredicatedSortedSet<E>	Decorates another `SortedSet` to validate that all additions match a specified predicate.

UnmodifiableSet<E>	Decorates another `Set` to ensure it can't be altered.
UnmodifiableSortedSet<E>	Decorates another `SortedSet` to ensure it can't be altered.

Package org.apache.commons.collections4.set Description

This package contains implementations of the Set, SortedSet and NavigableSet 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:

Unmodifiable - ensures the collection cannot be altered
Predicated - ensures that only elements that are valid according to a predicate can be added
Transformed - transforms each element added
ListOrdered - ensures that insertion order is retained
MapBackedSet - a set formed by decorating a Map
