- All Implemented Interfaces:
- Collection, Set
- public class CompositeSet
- extends CompositeCollection
- 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
public CompositeSet()
- Create an empty CompositeSet
CompositeSet
public CompositeSet(Set set)
- Create a CompositeSet with just
set
composited
- Parameters:
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
addComposited
public void addComposited(Collection c)
- 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 collisionUnsupportedOperationException
- if there is no SetMutator set, or
a CollectionMutator is set instead of a SetMutator- See Also:
CompositeCollection.CollectionMutator
,
CompositeSet.SetMutator
addComposited
public void addComposited(Collection c,
Collection d)
- Add two sets to this composite
- Overrides:
addComposited
in class CompositeCollection
- Throws:
IllegalArgumentException
- if c or d does not implement java.util.Set
addComposited
public void addComposited(Collection[] comps)
- 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)
- 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
- Overrides:
setMutator
in class CompositeCollection
- Following copied from class:
org.apache.commons.collections.collection.CompositeCollection
- Parameters:
mutator
- the mutator to use
remove
public boolean remove(Object obj)
- If a
CollectionMutator
is defined for this CompositeSet then this
method will be called anyway.
- Specified by:
remove
in interface Set
- Overrides:
remove
in class CompositeCollection
- Parameters:
obj
- Object to be removed- Returns:
- true if the object is removed, false otherwise
equals
public boolean equals(Object obj)
- Specified by:
equals
in interface Set
- Overrides:
equals
in class Object
- See Also:
Set.equals(java.lang.Object)
hashCode
public int hashCode()
- Specified by:
hashCode
in interface Set
- Overrides:
