org.apache.commons.collections.set.CompositeSet

All Implemented Interfaces:

Iterable, Collection, Set

@Deprecated(since="2021-04-30")
public class CompositeSet
extends CompositeCollection
implements Set

Deprecated.

Apache Commons Collections version 3.x is being deprecated from AEMaaCS. The upgraded version 4.4 of Commons Collections is already included as replacement. Customers are advised to upgrade to this version of the library. Please note: the package name was changed to org.apache.commons.collections4. Further note that there are AEM APIs currently exposing the old collections classes; these will be updated in upcoming releases.

Decorates a set of other sets to provide a single unified view.

Changes made to this set will actually be made on the decorated set. Add operations require the use of a pluggable strategy. If no strategy is provided then add is unsupported.

Since:

Commons Collections 3.0

CompositeSet

public CompositeSet()

Deprecated.

Create an empty CompositeSet

CompositeSet

public CompositeSet(Set set)

Deprecated.

Create a CompositeSet with just set composited

Parameters:

set - The initial set in the composite

CompositeSet

public CompositeSet(Set[] sets)

Deprecated.

Create a composite set with sets as the initial set of composited Sets

Method Details

addComposited

public void addComposited(Collection c)

Deprecated.

Add a Set to this composite

Overrides:

addComposited in class CompositeCollection

Parameters:

c - Must implement Set

Throws:

IllegalArgumentException - if c does not implement java.util.Set or if a SetMutator is set, but fails to resolve a collision

UnsupportedOperationException - if there is no SetMutator set, or a CollectionMutator is set instead of a SetMutator

• CompositeCollection.CollectionMutator
• CompositeSet.SetMutator

addComposited

public void addComposited(Collection c,
 Collection d)

Deprecated.

Add two sets to this composite

Overrides:

addComposited in class CompositeCollection

Parameters:

c - the first collection to add

d - the second collection to add

Throws:

IllegalArgumentException - if c or d does not implement java.util.Set

addComposited

public void addComposited(Collection[] comps)

Deprecated.

Add an array of sets to this composite

Overrides:

addComposited in class CompositeCollection

Parameters:

comps -

Throws:

IllegalArgumentException - if any of the collections in comps do not implement Set

setMutator

public void setMutator(CompositeCollection.CollectionMutator mutator)

Deprecated.

This can receive either a CompositeCollection.CollectionMutator or a CompositeSet.SetMutator. If a CompositeCollection.CollectionMutator is used than conflicts when adding composited sets will throw IllegalArgumentException

setMutator in class CompositeCollection

Parameters:

mutator - the mutator to use
