@GwtCompatible(serializable=true,
               emulated=true)
public final class ImmutableSortedMap<K,V>
extends ImmutableMap<K,V>
implements NavigableMap<K,V>

A NavigableMap whose contents will never change, with many other important properties detailed at ImmutableCollection.

Warning: as with any sorted collection, you are strongly advised not to use a Comparator or Comparable type whose comparison behavior is inconsistent with equals. That is, a.compareTo(b) or comparator.compare(a, b) should equal zero if and only if a.equals(b). If this advice is not followed, the resulting map will not correctly obey its specification.

See the Guava User Guide article on immutable collections.

toImmutableSortedMap

public static <T,K,V> Collector<T,?,ImmutableSortedMap<K,V>> toImmutableSortedMap(Comparator<? super K> comparator,
                                                                                                                Function<? super T,? extends K> keyFunction,
                                                                                                                Function<? super T,? extends V> valueFunction)

Returns a Collector that accumulates elements into an ImmutableSortedMap whose keys and values are the result of applying the provided mapping functions to the input elements. The generated map is sorted by the specified comparator.

If the mapped keys contain duplicates (according to the specified comparator), an IllegalArgumentException is thrown when the collection operation is performed. (This differs from the Collector returned by Collectors.toMap(Function, Function), which throws an IllegalStateException.)

Despite the method name, this method attempts to avoid actually copying the data when it is safe to do so. The exact circumstances under which a copy will or will not be performed are undocumented and subject to change.

Throws:

NullPointerException - if any key or value in map is null

naturalOrder

public static <K extends Comparable<?>,V> ImmutableSortedMap.Builder<K,V> naturalOrder()

Returns a builder that creates immutable sorted maps whose keys are ordered by their natural ordering. The sorted maps use Ordering.natural() as the comparator.

orderedBy

public static <K,V> ImmutableSortedMap.Builder<K,V> orderedBy(Comparator<K> comparator)

Returns a builder that creates immutable sorted maps with an explicit comparator. If the comparator has a more general type than the map's keys, such as creating a SortedMap<Integer, String> with a Comparator<Number>, use the ImmutableSortedMap.Builder constructor instead.

Throws:

NullPointerException - if comparator is null

reverseOrder

public static <K extends Comparable<?>,V> ImmutableSortedMap.Builder<K,V> reverseOrder()

Returns a builder that creates immutable sorted maps whose keys are ordered by the reverse of their natural ordering.

size

public int size()

Description copied from interface: java.util.Map

Returns the number of key-value mappings in this map. If the map contains more than Integer.MAX_VALUE elements, returns Integer.MAX_VALUE.

Specified by:

size in interface Map<K,V>

Returns:

the number of key-value mappings in this map

forEach

public void forEach(BiConsumer<? super K,? super V> action)

Description copied from interface: java.util.Map

Performs the given action for each entry in this map until all entries have been processed or the action throws an exception. Unless otherwise specified by the implementing class, actions are performed in the order of entry set iteration (if an iteration order is specified.) Exceptions thrown by the action are relayed to the caller.

Specified by:

forEach in interface Map<K,V>

Parameters:

action - The action to be performed for each entry

get

public V get(@Nullable Object key)

Description copied from interface: java.util.Map

Returns the value to which the specified key is mapped, or null if this map contains no mapping for the key.

More formally, if this map contains a mapping from a key k to a value v such that Objects.equals(key, k), then this method returns v; otherwise it returns null. (There can be at most one such mapping.)

If this map permits null values, then a return value of null does not necessarily indicate that the map contains no mapping for the key; it's also possible that the map explicitly maps the key to null. The containsKey operation may be used to distinguish these two cases.

Specified by:

get in interface Map<K,V>

Specified by:

get in class ImmutableMap<K,V>

Parameters:

key - the key whose associated value is to be returned

Returns:

the value to which the specified key is mapped, or null if this map contains no mapping for the key

Specified by:

values in interface Map<K,V>

Specified by:

values in interface SortedMap<K,V>

Overrides:

values in class ImmutableMap<K,V>

Returns:

a collection view of the values contained in this map

comparator

public Comparator<? super K> comparator()

Returns the comparator that orders the keys, which is Ordering.natural() when the natural ordering of the keys is used. Note that its behavior is not consistent with TreeMap.comparator(), which returns null to indicate natural ordering.

Specified by:

comparator in interface SortedMap<K,V>

Returns:

the comparator used to order the keys in this map, or null if this map uses the natural ordering of its keys

firstKey

public K firstKey()

Description copied from interface: java.util.SortedMap

Returns a NavigableSet view of the keys contained in this map. The set's iterator returns the keys in ascending order. The set is backed by the map, so changes to the map are reflected in the set, and vice-versa. If the map is modified while an iteration over the set is in progress (except through the iterator's own remove operation), the results of the iteration are undefined. The set supports element removal, which removes the corresponding mapping from the map, via the Iterator.remove, Set.remove, removeAll, retainAll, and clear operations. It does not support the add or addAll operations.

Specified by:

navigableKeySet in interface NavigableMap<K,V>

Returns:

a navigable set view of the keys in this map

descendingKeySet

public ImmutableSortedSet<K> descendingKeySet()

Description copied from interface: java.util.NavigableMap

Returns a reverse order NavigableSet view of the keys contained in this map. The set's iterator returns the keys in descending order. The set is backed by the map, so changes to the map are reflected in the set, and vice-versa. If the map is modified while an iteration over the set is in progress (except through the iterator's own remove operation), the results of the iteration are undefined. The set supports element removal, which removes the corresponding mapping from the map, via the Iterator.remove, Set.remove, removeAll, retainAll, and clear operations. It does not support the add or addAll operations.

Specified by:
