Constructor Details

AbstractMultiMap

public AbstractMultiMap()

Method Details

containsValue

public boolean containsValue(V value)

Specified by:

containsValue in interface MultiMap<K,V>

Returns:

true if this multimap contains at least one key-value pair with the value value. Note that this operation may be slow compared to MultiMap.containsKey(Object) in some implementations.

entrySet

public Set<Map.Entry<K,V>> entrySet()

Specified by:

entrySet in interface MultiMap<K,V>

Returns:

an unmodifiable view of all key-value pairs contained in this multimap, as Map.Entry instances.

entryIterator

protected abstract Iterator<Map.Entry<K,V>> entryIterator()

values

public Collection<V> values()

Specified by:

values in interface MultiMap<K,V>

Returns:

an unmodifiable view collection containing the value from each key-value pair contained in this multimap, without collapsing duplicates (so values().size() == size()).

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface MultiMap<K,V>

Returns:

true if this multimap is empty.

equals

public boolean equals(Object o)

Overrides:

equals in class Object

toString

public String toString()

Overrides:

toString in class Object
