getFirst

public V getFirst()

Description copied from interface: RichIterable

Returns the first element of an iterable. In the case of a List it is the element at the first index. In the case of any other Collection, it is the first element that would be returned during an iteration. If the iterable is empty, null is returned. If null is a valid element of the container, then a developer would need to check to see if the iterable is empty to validate that a null result was not due to the container being empty.

The order of Sets are not guaranteed (except for TreeSets and other Ordered Set implementations), so if you use this method, the first element could be any element from the Set.

Specified by:

getFirst in interface RichIterable<K>

getLast

public V getLast()

Description copied from interface: RichIterable

Returns the last element of an iterable. In the case of a List it is the element at the last index. In the case of any other Collection, it is the last element that would be returned during an iteration. If the iterable is empty, null is returned. If null is a valid element of the container, then a developer would need to check to see if the iterable is empty to validate that a null result was not due to the container being empty.

The order of Sets are not guaranteed (except for TreeSets and other Ordered Set implementations), so if you use this method, the last element could be any element from the Set.

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.

asLazy

public LazyIterable<V> asLazy()

Description copied from interface: RichIterable

Returns a lazy (deferred) iterable, most likely implemented by calling LazyIterate.adapt(this).

Specified by:

asLazy in interface RichIterable<K>

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.

flatCollect

public <V1> RichIterable<V1> flatCollect(Function<? super V,? extends Iterable<V1>> function)

Description copied from interface: RichIterable

flatCollect is a special case of RichIterable.collect(Function). With collect, when the Function returns a collection, the result is a collection of collections. flatCollect outputs a single "flattened" collection instead. This method is commonly called flatMap.

Consider the following example where we have a Person class, and each Person has a list of Address objects. Take the following Function:

 Function<Person, List<Address>> addressFunction = Person::getAddresses;
 RichIterable<Person> people = ...;
 

Using collect returns a collection of collections of addresses.

 RichIterable<List<Address>> addresses = people.collect(addressFunction);
 

Using flatCollect returns a single flattened list of addresses.

 RichIterable<Address> addresses = people.flatCollect(addressFunction);
 

Specified by:

flatCollect in interface RichIterable<K>

Parameters:

function - The Function to apply

Returns:

a new flattened collection produced by applying the given function

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.

withoutAllKeys

public MutableBiMap<K,V> withoutAllKeys(Iterable<? extends K> keys)

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.
