Method Detail

comparator

public CharComparator comparator()

Description copied from interface: Char2CharSortedMap

Returns the comparator associated with this sorted set, or null if it uses its keys' natural ordering.

Note that this specification strengthens the one given in SortedMap.comparator().

Specified by:

comparator in interface Char2CharSortedMap

Specified by:

comparator in interface SortedMap<Character,Character>

See Also:

SortedMap.comparator()

char2CharEntrySet

public ObjectSortedSet<Char2CharMap.Entry> char2CharEntrySet()

Description copied from interface: Char2CharMap

Returns a type-specific set view of the mappings contained in this map.

This method is necessary because there is no inheritance along type parameters: it is thus impossible to strengthen Map.entrySet() so that it returns an ObjectSet of type-specific entries (the latter makes it possible to access keys and values with type-specific methods).

Specified by:

char2CharEntrySet in interface Char2CharMap

Specified by:

char2CharEntrySet in interface Char2CharSortedMap

Overrides:

char2CharEntrySet in class Char2CharMaps.EmptyMap

Returns:

a type-specific set view of the mappings contained in this map.

See Also:

Map.entrySet()

entrySet

@Deprecated
public ObjectSortedSet<Map.Entry<Character,Character>> entrySet()

Deprecated. Please use the corresponding type-specific method instead.

Returns a sorted-set view of the mappings contained in this map.

Note that this specification strengthens the one given in the corresponding type-specific unsorted map.

Specified by:

entrySet in interface Char2CharMap

Specified by:

entrySet in interface Char2CharSortedMap

Specified by:

entrySet in interface Map<Character,Character>

Specified by:

entrySet in interface SortedMap<Character,Character>

Returns:

a sorted-set view of the mappings contained in this map.

See Also:

SortedMap.entrySet()

keySet

public CharSortedSet keySet()

Description copied from interface: Char2CharMap

Note that this specification strengthens the one given in Map.keySet().

Specified by:

keySet in interface Char2CharMap

Specified by:

keySet in interface Char2CharSortedMap

Specified by:

keySet in interface Map<Character,Character>

Specified by:

keySet in interface SortedMap<Character,Character>

Overrides:

keySet in class Char2CharMaps.EmptyMap

Returns:

a set view of the keys contained in this map.

See Also:

Map.keySet()

subMap

public Char2CharSortedMap subMap(char from,
                                 char to)

Description copied from interface: Char2CharSortedMap

Returns a view of the portion of this sorted map whose keys range from fromKey, inclusive, to toKey, exclusive.

Note that this specification strengthens the one given in SortedMap.subMap(Object,Object).

Specified by:

subMap in interface Char2CharSortedMap

See Also:

SortedMap.subMap(Object,Object)

headMap

public Char2CharSortedMap headMap(char to)

Description copied from interface: Char2CharSortedMap

Returns a view of the portion of this sorted map whose keys are strictly less than toKey.

Note that this specification strengthens the one given in SortedMap.headMap(Object).

Specified by:

headMap in interface Char2CharSortedMap

See Also:

SortedMap.headMap(Object)

tailMap

public Char2CharSortedMap tailMap(char from)

Description copied from interface: Char2CharSortedMap

Returns a view of the portion of this sorted map whose keys are greater than or equal to fromKey.

Note that this specification strengthens the one given in SortedMap.tailMap(Object).

Specified by:

tailMap in interface Char2CharSortedMap

See Also:

SortedMap.tailMap(Object)

firstCharKey
