Method Detail

comparator

public CharComparator comparator()

Description copied from interface: Char2ReferenceSortedMap

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 Char2ReferenceSortedMap<V>

Specified by:

comparator in interface SortedMap<Character,V>

See Also:

SortedMap.comparator()

char2ReferenceEntrySet

public ObjectSortedSet<Char2ReferenceMap.Entry<V>> char2ReferenceEntrySet()

Description copied from interface: Char2ReferenceMap

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 Char2ReferenceMap.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:

char2ReferenceEntrySet in interface Char2ReferenceMap<V>

Specified by:

char2ReferenceEntrySet in interface Char2ReferenceSortedMap<V>

Overrides:

char2ReferenceEntrySet in class Char2ReferenceMaps.EmptyMap<V>

Returns:

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

See Also:

Char2ReferenceMap.entrySet()

entrySet

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

Description copied from interface: Char2ReferenceMap

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 Char2ReferenceMap<V>

Specified by:

entrySet in interface Char2ReferenceSortedMap<V>

Specified by:

entrySet in interface Map<Character,V>

Specified by:

entrySet in interface SortedMap<Character,V>

Overrides:

entrySet in class Char2ReferenceMaps.EmptyMap<V>

Returns:

a set view of the mappings contained in this map.

See Also:

Map.entrySet()

keySet

public CharSortedSet keySet()

Description copied from interface: Char2ReferenceMap

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 Char2ReferenceMap<V>

Specified by:

keySet in interface Char2ReferenceSortedMap<V>

Specified by:

keySet in interface Map<Character,V>

Specified by:

keySet in interface SortedMap<Character,V>

Overrides:

keySet in class Char2ReferenceMaps.EmptyMap<V>

Returns:

a set view of the keys contained in this map.

See Also:

Map.keySet()

public Char2ReferenceSortedMap<V> subMap(char from,
                                char to)

headMap

public Char2ReferenceSortedMap<V> headMap(Character oto)

Description copied from interface: Char2ReferenceSortedMap
