MapMapTwoKeyMap

public MapMapTwoKeyMap(Map<K1,Map<K2,V>> map,
 SSupplier<Map<K2,V>> mapFactory)

Method Details

get

@Nullable
public Map<K2,V> get(K1 key1)

Specified by:

get in interface TwoKeyMap<K1,K2,V>

Returns:

an unmodifiable view of the second-level map for key1, or null if this map contains no mapping for the key.

put

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

Description copied from interface: TwoKeyMap

Associates the specified value with the specified two-key pair in this map. If the map previously contained a mapping for the keys, the old value is replaced by the specified value.

Specified by:

put in interface TwoKeyMap<K1,K2,V>

Returns:

the previous value associated with key1 and key2, or null if there was no mapping for key2.

putAll

public void putAll(@Nonnull
 K1 key1,
 @Nonnull
 Map<K2,V> map)

Description copied from interface: TwoKeyMap

Copies all the mappings from the specified map to second-level map associated with key1.

Specified by:

putAll in interface TwoKeyMap<K1,K2,V>

putAll

public void putAll(@Nonnull
 TwoKeyMap<K1,K2,V> twoKeyMap)

Description copied from interface: TwoKeyMap

Copies all the mappings from the specified two-key map to this map.

Specified by:

putAll in interface TwoKeyMap<K1,K2,V>

remove

@Nullable
public V remove(K1 key1,
 K2 key2)

Description copied from interface: TwoKeyMap

Removes the mapping for a key-pair from this map if it is present.

Specified by:

remove in interface TwoKeyMap<K1,K2,V>

Returns:

the value to which this map previously associated the key pair, or null if the map contained no mapping for the key pair.

removeAll

public boolean removeAll(K1 key1)

Description copied from interface: TwoKeyMap

Removes all mappings with key1 as the first key in this map.

Specified by:

removeAll in interface TwoKeyMap<K1,K2,V>

Returns:

true if the two-key map changed.

replaceALl

public void replaceALl(TriFunction<? super K1,? super K2,? super V,? extends V> function)

Description copied from interface: TwoKeyMap

Replaces each entry's value with the result of invoking the given function on that entry until all entries have been processed or the function throws an exception.

Specified by:

replaceALl in interface TwoKeyMap<K1,K2,V>

keySet

public Set<K1> keySet()

Specified by:

keySet in interface TwoKeyMap<K1,K2,V>

Returns:

an unmodifiable view of first keys of all mappings contained in this two-key map. Note that the result contains a key if and only if this map contains at least one mapping with the key as the first key.

entryIterator

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

Specified by:

entryIterator in class AbstractTwoKeyMap<K1,K2,V>

clear

public void clear()

Description copied from interface: TwoKeyMap

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

Specified by:

clear in interface TwoKeyMap<K1,K2,V>

size

public int size()

Specified by:

size in interface TwoKeyMap<K1,K2,V>

Returns:

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