removeAll

public boolean removeAll(Collection<?> coll)

Specified by:

removeAll in interface Collection<K>

Overrides:

removeAll in class AbstractCollectionDecorator<E>

retainAll

public boolean retainAll(Collection<?> coll)

This implementation iterates over the elements of this bidi map, checking each element in turn to see if it's contained in coll. If it's not contained, it's removed from this bidi map. As a consequence, it is advised to use a collection type for coll that provides a fast (e.g. O(1)) implementation of Collection.contains(Object).

Specified by:

retainAll in interface Collection<K>

Overrides:

retainAll in class AbstractCollectionDecorator<E>

clear

public void clear()

Specified by:

clear in interface Collection<K>

Overrides:

clear in class AbstractCollectionDecorator<E>
