Class AbstractMultiValuedMap.WrappedCollection

java.lang.Object

org.apache.commons.collections4.multimap.AbstractMultiValuedMap.WrappedCollection

All Implemented Interfaces:

java.lang.Iterable<V>, java.util.Collection<V>

Direct Known Subclasses:

AbstractListValuedMap.WrappedList, AbstractSetValuedMap.WrappedSet

Enclosing class:

AbstractMultiValuedMap<K,V>

class AbstractMultiValuedMap.WrappedCollection
extends java.lang.Object
implements java.util.Collection<V>

Wrapped collection to handle add and remove on the collection returned by get(object).

Currently, the wrapped collection is not cached and has to be retrieved from the underlying map. This is safe, but not very efficient and should be improved in subsequent releases. For this purpose, the scope of this collection is set to package private to simplify later refactoring.
