Class CompositeSet
- Collection, Set
public class CompositeSet
implements Set
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 and remove operations require the use of a pluggable strategy. If no
strategy is provided then add and remove are unsupported.

CompositeSet(Set set) - Create a CompositeSet with just
set composited
|
CompositeSet(Set[] sets) - Create a composite set with sets as the initial set of composited Sets
|
void | addComposited(Collection c) - Add a Set to this composite
|
void | addComposited(Collection c, Collection d) - Add two sets to this composite
|
void | addComposited(Collection[] comps) - Add an array of sets to this composite
|
boolean | equals(Object obj)
|
int | hashCode()
|
boolean | remove(Object obj) - If a
CollectionMutator is defined for this CompositeSet then this
method will be called anyway.

CompositeSet
public CompositeSet(Set set)
Create a CompositeSet with just set
composited
set
- The initial set in the composite
CompositeSet
public CompositeSet(Set[] sets)
Create a composite set with sets as the initial set of composited Sets
equals
public boolean equals(Object obj)
hashCode
public int hashCode()
remove
public boolean remove(Object obj)
If a CollectionMutator
is defined for this CompositeSet then this
method will be called anyway.
- remove in interface CompositeCollection
obj
- Object to be removed
- true if the object is removed, false otherwise
setMutator
public void setMutator(CompositeCollection.CollectionMutator mutator)
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 interface CompositeCollection
