               AbstractDualBidiMap<K,V> parent)

Constructs a new view of the BidiMap.

Parameters:

hashCode

public int hashCode()

Specified by:

removeAll

public boolean removeAll(java.util.Collection<?> coll)

Specified by:

removeAll in interface java.util.Collection<K>

Overrides:

removeAll in class AbstractCollectionDecorator<E>

retainAll

public boolean retainAll(java.util.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 java.util.Collection<K>

Overrides:

retainAll in class AbstractCollectionDecorator<E>

clear

public void clear()

Specified by:

clear in interface java.util.Collection<K>

Overrides:

clear in class AbstractCollectionDecorator<E>
