Method Detail

comparator

public CharComparator comparator()

Description copied from interface: Char2IntSortedMap

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 Char2IntSortedMap

Specified by:

comparator in interface SortedMap<Character,Integer>

See Also:

SortedMap.comparator()

char2IntEntrySet

public ObjectSortedSet<Char2IntMap.Entry> char2IntEntrySet()

Description copied from interface: Char2IntMap

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 Char2IntMap.entrySet() so that it returns an ObjectSet of objects of type Map.Entry (the latter makes it possible to access keys and values with type-specific methods).

Specified by:

char2IntEntrySet in interface Char2IntMap

Specified by:

char2IntEntrySet in interface Char2IntSortedMap

Overrides:

char2IntEntrySet in class Char2IntMaps.EmptyMap

Returns:

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

See Also:

Char2IntMap.entrySet()

entrySet

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

Description copied from interface: Char2IntMap

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

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

Specified by:

entrySet in interface Char2IntMap

Specified by:

entrySet in interface Char2IntSortedMap

Specified by:

entrySet in interface Map<Character,Integer>

Specified by:

entrySet in interface SortedMap<Character,Integer>

Overrides:

entrySet in class Char2IntMaps.EmptyMap

Returns:

a set view of the mappings contained in this map.

See Also:

Map.entrySet()

keySet

public CharSortedSet keySet()

Description copied from interface: Char2IntMap

Returns a set view of the keys contained in this map.

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

Specified by:

keySet in interface Char2IntMap

Specified by:

keySet in interface Char2IntSortedMap

Specified by:

keySet in interface Map<Character,Integer>

Specified by:

keySet in interface SortedMap<Character,Integer>

Overrides:

keySet in class Char2IntMaps.EmptyMap

Returns:

a set view of the keys contained in this map.

See Also:

Map.keySet()

subMap

public Char2IntSortedMap subMap(char from,
                       char to)

Description copied from interface: Char2IntSortedMap

SortedMap.subMap(Object,Object)

headMap

public Char2IntSortedMap headMap(char to)

Description copied from interface: Char2IntSortedMap

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

SortedMap.headMap(Object)

tailMap

public Char2IntSortedMap tailMap(char from)

Description copied from interface: Char2IntSortedMap

tailMap

public Char2IntSortedMap tailMap(Character ofrom)

Description copied from interface: Char2IntSortedMap
