withKeyValue

public MutableOrderedMap<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.

Specified by:

withKeyValue in interface MutableMapIterable<K,V>

See Also:

• Map.put(Object, Object)

Specified by:

putAllMapIterable in interface MutableMapIterable<K,V>

withAllKeyValues

public MutableOrderedMap<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 MutableOrderedMap<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 MutableOrderedMap<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.

asUnmodifiable

public MutableOrderedMap<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.

toImmutable

asSynchronized

public MutableOrderedMap<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.

flip

public MutableListMultimap<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.

flatCollect

public <R> MutableList<R> flatCollect(Function<? super V,? extends Iterable<R>> 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);

groupBy

public <VV> MutableListMultimap<VV,V> groupBy(Function<? super V,? extends VV> function)

Description copied from interface: RichIterable

For each element of the iterable, the function is evaluated and the results of these evaluations are collected into a new multimap, where the transformed value is the key and the original values are added to the same (or similar) species of collection as the source iterable.

Example using a Java 8 method reference:

 Multimap<String, Person> peopleByLastName =
     people.groupBy(Person::getLastName);
 

Example using an anonymous inner class:

 Multimap<String, Person> peopleByLastName =
     people.groupBy(new Function<Person, String>()
     {
         public String valueOf(Person person)
         {
             return person.getLastName();
         }
     });

The predicate is evaluated for each element at the same position of each OrderedIterable in a forward iteration order. This is a short circuit pattern.

     {
