 SSupplier<MultiMap<K2,V>> multimapFactory)

Method Details

contains

public boolean contains(K1 key1,
 K2 key2,
 V value)

Returns:

true if given key1-key2-value mapping is contained in this two-key multimap.

containsKey

public boolean containsKey(K1 key1,
 K2 key2)

Returns:

true if this two-key multimap contains the mapping with key1 as the first key and key2 as the second key.

containsKey

public boolean containsKey(K1 key1)

Returns:

true if this two-key multimap contains at least one mapping with key1 as the first key.

containsValue

public boolean containsValue(V value)

Returns:

true if this two-key multimap contains at least one mapping with value as the value. Note that this operation may be slow compared to TwoKeyMultiMap.containsKey(Object).

get

public Set<V> get(K1 key1,
 K2 key2)

Returns:

an unmodifiable view of the values associated with given keys in this multimap, if the two-key pair is absent; otherwise, returns an empty set.

get

public MultiMap<K2,V> get(K1 key1)

Returns:

an unmodifiable view of the values associated with given key in this two-key multimap, if the key is absent; otherwise, returns an empty multimap.

put

public boolean put(@Nonnull
 K1 key1,
 @Nonnull
 K2 key2,
 @Nonnull
 V value)

Description copied from interface: TwoKeyMultiMap

Stores a key1-key2-value triple in this two-key multimap.

Returns:

true if this two-key multimap changed.

remove

public boolean remove(K1 key1,
 K2 key2,
 V value)

Description copied from interface: TwoKeyMultiMap

Removes a single key1-key2-value triple from this two-key multimap, if it exists.

Returns:

true if the two-key multimap changed

removeAll

public boolean removeAll(K1 key1,
 K2 key2)

Description copied from interface: TwoKeyMultiMap

Removes all values associated with the two-key pair.

Returns:

true if the multimap changed.

entryIterator

protected Iterator<TwoKeyMap.Entry<K1,K2,V>> entryIterator()

Specified by:

entryIterator in class AbstractTwoKeyMultiMap<K1,K2,V>

twoKeySet

public Set<Pair<K1,K2>> twoKeySet()

Returns:

an unmodifiable view of all distinct two-key pairs contained in this two-key multimap. Note that the result contains a two-key pair if and only if this map maps that key pair to at least one non-null value.

clear

public void clear()

Description copied from interface: TwoKeyMultiMap

Removes all the mappings from this map. The map will be empty after this call returns.

size

public int size()

Returns:

the number of key1-key2-value mappings in this map.

hashCode

public int hashCode()

Overrides:

hashCode in class Object
