Apache Commons Collections 4.4 · org.apache.commons.collections4.set

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

Class Summary

Modifier and Type	Class and Description
public abstract class	AbstractNavigableSetDecorator< the type of the elements in the navigable set E> Decorates another `NavigableSet` to provide additional behaviour.
public abstract class	AbstractSerializableSetDecorator< the type of the elements in this set E> Serializable subclass of AbstractSetDecorator.
public abstract class	AbstractSetDecorator< the type of the elements in this set E> Decorates another `Set` to provide additional behaviour.
public abstract class	AbstractSortedSetDecorator< the type of the elements in the sorted set E> Decorates another `SortedSet` to provide additional behaviour.
public class	CompositeSet< the type of the elements in this set E> Decorates a set of other sets to provide a single unified view.
public class	ListOrderedSet< the type of the elements in this set E> Decorates another `Set` to ensure that the order of addition is retained and used by the iterator.
public class	MapBackedSet< the type of the elements in this set E, the dummy value type in this map V> Decorates a `Map` to obtain `Set` behaviour.
public class	PredicatedNavigableSet< the type of the elements in this set E> Decorates another `NavigableSet` to validate that all additions match a specified predicate.
public class	PredicatedSet< the type of the elements in this set E> Decorates another `Set` to validate that all additions match a specified predicate.
public class	PredicatedSortedSet< the type of the elements in this set E> Decorates another `SortedSet` to validate that all additions match a specified predicate.
public class	TransformedNavigableSet< the type of the elements in this set E> Decorates another `NavigableSet` to transform objects that are added.
public class	TransformedSet< the type of the elements in this set E> Decorates another `Set` to transform objects that are added.
public class	TransformedSortedSet< the type of the elements in this set E> Decorates another `SortedSet` to transform objects that are added.
public class	UnmodifiableNavigableSet< the type of the elements in this set E> Decorates another `NavigableSet` to ensure it can't be altered.
public class	UnmodifiableSet< the type of the elements in this set E> Decorates another `Set` to ensure it can't be altered.
public class	UnmodifiableSortedSet< the type of the elements in this set E> Decorates another `SortedSet` to ensure it can't be altered.
