Field Detail

parent

protected final AbstractDualBidiMap<K,V> parent

The parent map

Constructor Detail

View

protected View(java.util.Collection<E> coll,
               AbstractDualBidiMap<K,V> parent)

Constructs a new view of the BidiMap.

Parameters:

coll - the collection view being decorated

parent - the parent BidiMap

Method Detail

equals

public boolean equals(java.lang.Object object)

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

removeAll

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

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).

Overrides:

retainAll in class AbstractCollectionDecorator<E>

clear

public void clear()

Overrides:

clear in class AbstractCollectionDecorator<E>
