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.

TransformedSet<E>	Decorates another Set to transform objects that are added.
TransformedSortedSet<E>	Decorates another SortedSet to transform objects that are added.

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
