Package org.apache.commons.collections.set
This package contains implementations of the
Set
and
SortedSet
interfaces.
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. |
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
