Interface MutableSortedMap<K,​V>

All Superinterfaces:
Cloneable, InternalIterable<V>, Iterable<V>, Map<K,​V>, MapIterable<K,​V>, MutableMapIterable<K,​V>, OrderedIterable<V>, ReversibleIterable<V>, RichIterable<V>, SortedMap<K,​V>, SortedMapIterable<K,​V>

public interface MutableSortedMap<K,​V>
extends MutableMapIterable<K,​V>, SortedMapIterable<K,​V>, SortedMap<K,​V>, Cloneable
A MutableSortedMap is similar to a JCF Map but adds additional useful internal iterator methods. The MutableSortedMap interface additionally implements some of the methods in the Smalltalk Dictionary protocol.

  • Method Details

    • newEmpty

      MutableSortedMap<K,​V> newEmpty()
      Creates a new instance of the same type with the same internal Comparator.
      Specified by:
      newEmpty in interface MutableMapIterable<K,​V>

    • collectKeysAndValues

      <E> MutableSortedMap<K,​V> collectKeysAndValues​(Iterable<E> iterable, Function<? super E,​? extends K> keyFunction, Function<? super E,​? extends V> valueFunction)
      Adds all the entries derived from iterable to this. The key and value for each entry is determined by applying the keyFunction and valueFunction to each item in collection. Any entry in map that has the same key as an entry in this will have it's value replaced by that in map.

    • getIfAbsentPutWith

      <P> V getIfAbsentPutWith​(K key, Function<? super P,​? extends V> function, P parameter)
      Return the value in the Map that corresponds to the specified key, or if there is no value at the key, return the result of evaluating the specified one argument Function using the specified parameter, and put that value in the map at the specified key.
      Specified by:
      getIfAbsentPutWith in interface MutableMapIterable<K,​V>

    • asUnmodifiable

      MutableSortedMap<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 MutableMapIterable<K,​V>
      Returns:
      an unmodifiable view of this map.
      See Also:
      Collections.unmodifiableMap(Map)

    • asSynchronized

      MutableSortedMap<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.

      Collections.synchronizedMap(Map)

    • flip

      MutableSortedSetMultimap<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.

     peopleByCity.select((city, person) -> city.getName().equals("Anytown") && person.getLastName().equals("Smith"));

    • flatCollect

      <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);

      E.g. return a Collection of Person elements where the person has an age greater than or equal to 18 years

      Example using a Java 8 lambda expression: 

       RichIterable<Person> selected =
     people.selectWith((Person person, Integer age) -> person.getAge()>= age, Integer.valueOf(18));

    • withKeyValue

      MutableSortedMap<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.

    • withoutKey

      MutableSortedMap<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.
