Method Details

of

public static <K, V> SynchronizedBiMap<K,V> of(MutableBiMap<K,V> map)

This method will take a MutableBiMap and wrap it directly in a SynchronizedBiMap.

forcePut

public V forcePut(K key, V value)

Description copied from interface: MutableBiMap

Similar to MutableBiMap.put(Object, Object), except that it quietly removes any existing entry with the same value before putting the key-value pair.

Specified by:

forcePut in interface MutableBiMap<K,V>

asSynchronized

public MutableBiMap<K,V> asSynchronized()

Description copied from interface: MutableMapIterable

Returns a synchronized wrapper backed by this map. This is the equivalent of calling Collections.synchronizedMap(this) only with the more feature rich return type of MutableMapIterable.

The preferred way of iterating over a synchronized map is to use the forEachKey(), forEachValue() and forEachKeyValue() methods which are properly synchronized internally.

  MutableMap synchedMap = map.asSynchronized();

  synchedMap.forEachKey(key -> ... );
  synchedMap.forEachValue(value -> ... );
  synchedMap.forEachKeyValue((key, value) -> ... );
 

If you want to iterate imperatively over the keySet(), values(), or entrySet(), you will need to protect the iteration by wrapping the code in a synchronized block on the map.

Specified by:

asSynchronized in interface MutableBiMap<K,V>

Specified by:

asSynchronized in interface MutableMapIterable<K,V>

See Also:

Collections.synchronizedMap(Map)

asUnmodifiable

public MutableBiMap<K,V> asUnmodifiable()

Description copied from interface: MutableMapIterable

Returns an unmodifiable view of this map. This is the equivalent of using Collections.unmodifiableMap(this) only with a return type that supports the full iteration protocols available on MutableMapIterable. Methods which would mutate the underlying map will throw UnsupportedOperationExceptions.

Specified by:

asUnmodifiable in interface MutableBiMap<K,V>

Specified by:

asUnmodifiable in interface MutableMapIterable<K,V>

Returns:

an unmodifiable view of this map.

Specified by:

clone in interface MutableBiMap<K,V>

tap

public MutableBiMap<K,V> tap(Procedure<? super V> procedure)

Description copied from interface: RichIterable

Executes the Procedure for each element in the iterable and returns this.

Example using a Java 8 lambda expression:

 RichIterable<Person> tapped =
     people.tap(person -> LOGGER.info(person.getName()));
 

Example using an anonymous inner class:

flip

public MutableSetMultimap<V,K> flip()

Description copied from interface: MapIterable

Given a map from Domain -> Range return a multimap from Range -> Domain. We chose the name 'flip' rather than 'invert' or 'transpose' since this method does not have the property of applying twice returns the original.

Since the keys in the input are unique, the values in the output are unique, so the return type should be a SetMultimap. However since SetMultimap and SortedSetMultimap don't inherit from one another, SetMultimap here does not allow SortedMapIterable to have a SortedSetMultimap return. Thus we compromise and call this Multimap, even though all implementations will be a SetMultimap or SortedSetMultimap.

groupByUniqueKey

public <VV> MutableBiMap<VV,V> groupByUniqueKey(Function<? super V,? extends VV> function)

Description copied from interface: RichIterable

For each element of the iterable, the function is evaluated and he results of these evaluations are collected into a new map, where the transformed value is the key. The generated keys must each be unique, or else an exception is thrown.

@Deprecated public <S> MutableSet<Pair<V,S>> zip(Iterable<S> that)

Deprecated.

in 8.0. Use OrderedIterable.zip(Iterable) instead.

Description copied from interface: RichIterable

Returns a RichIterable formed from this RichIterable and another RichIterable by combining corresponding elements in pairs. If one of the two RichIterables is longer than the other, its remaining elements are ignored.

Type Parameters:

S - the type of the second half of the returned pairs

Parameters:

that - The RichIterable providing the second half of each result pair

Returns:

A new RichIterable containing pairs consisting of corresponding elements of this RichIterable and that. The length of the returned RichIterable is the minimum of the lengths of this RichIterable and that.

withKeyValue

public MutableBiMap<K,V> withKeyValue(K key, V value)

Description copied from interface: MutableMapIterable

This method allows mutable, fixed size, and immutable maps the ability to add elements to their existing elements. In order to support fixed size maps, a new instance of a map would have to be returned including the keys and values of the original plus the additional key and value. In the case of mutable maps, the original map is modified and then returned. In order to use this method properly with mutable and fixed size maps the following approach must be taken:

 map = map.withKeyValue("new key", "new value");
 

In the case of FixedSizeMap, a new instance will be returned by withKeyValue, and any variables that previously referenced the original map will need to be redirected to reference the new instance. In the case of a FastMap or UnifiedMap, you will be replacing the reference to map with map, since FastMap and UnifiedMap will both return "this" after calling put on themselves.

withAllKeyValues

public MutableBiMap<K,V> withAllKeyValues(Iterable<? extends Pair<? extends K,? extends V>> keyValues)

Description copied from interface: MutableMapIterable

This method allows mutable, fixed size, and immutable maps the ability to add elements to their existing elements. In order to support fixed size maps, a new instance of a map would have to be returned including the keys and values of the original plus all of the additional keys and values. In the case of mutable maps, the original map is modified and then returned. In order to use this method properly with mutable and fixed size maps the following approach must be taken:

 map = map.withAllKeyValues(FastList.newListWith(PairImpl.of("new key", "new value")));
 

In the case of FixedSizeMap, a new instance will be returned by withAllKeyValues, and any variables that previously referenced the original map will need to be redirected to reference the new instance. In the case of a FastMap or UnifiedMap, you will be replacing the reference to map with map, since FastMap and UnifiedMap will both return "this" after calling put on themselves.

withoutKey

public MutableBiMap<K,V> withoutKey(K key)

Description copied from interface: MutableMapIterable

This method allows mutable, fixed size, and immutable maps the ability to remove elements from their existing elements. In order to support fixed size maps, a new instance of a map would have to be returned including the keys and values of the original minus the key and value to be removed. In the case of mutable maps, the original map is modified and then returned. In order to use this method properly with mutable and fixed size maps the following approach must be taken:

 map = map.withoutKey("key");
 

In the case of FixedSizeMap, a new instance will be returned by withoutKey, and any variables that previously referenced the original map will need to be redirected to reference the new instance. In the case of a FastMap or UnifiedMap, you will be replacing the reference to map with map, since FastMap and UnifiedMap will both return "this" after calling remove on themselves.

Description copied from interface: MutableMapIterable

This method allows mutable, fixed size, and immutable maps the ability to remove elements from their existing elements. In order to support fixed size maps, a new instance of a map would have to be returned including the keys and values of the original minus all of the keys and values to be removed. In the case of mutable maps, the original map is modified and then returned. In order to use this method properly with mutable and fixed size maps the following approach must be taken:

 map = map.withoutAllKeys(FastList.newListWith("key1", "key2"));
 

In the case of FixedSizeMap, a new instance will be returned by withoutAllKeys, and any variables that previously referenced the original map will need to be redirected to reference the new instance. In the case of a FastMap or UnifiedMap, you will be replacing the reference to map with map, since FastMap and UnifiedMap will both return "this" after calling remove on themselves.
