Method Detail

comparator

public CharComparator comparator()

Description copied from interface: Char2DoubleSortedMap

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 Char2DoubleSortedMap

Specified by:

comparator in interface SortedMap<Character,Double>

See Also:

SortedMap.comparator()

char2DoubleEntrySet

public ObjectSortedSet<Char2DoubleMap.Entry> char2DoubleEntrySet()

Description copied from interface: Char2DoubleMap

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 Char2DoubleMap.entrySet() so that it returns an ObjectSet of objects of type Char2DoubleMap.Entry (the latter makes it possible to access keys and values with type-specific methods).

Specified by:

char2DoubleEntrySet in interface Char2DoubleMap

Specified by:

char2DoubleEntrySet in interface Char2DoubleSortedMap

Overrides:

char2DoubleEntrySet in class Char2DoubleMaps.EmptyMap

Returns:

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

See Also:

Char2DoubleMap.entrySet()

entrySet

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

Description copied from interface: Char2DoubleMap

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 Char2DoubleMap

Specified by:

entrySet in interface Char2DoubleSortedMap

Specified by:

entrySet in interface Map<Character,Double>

Overrides:

entrySet in class Char2DoubleMaps.EmptyMap

Returns:

a set view of the mappings contained in this map.

See Also:

Map.entrySet()

keySet

public CharSortedSet keySet()

Description copied from interface: Char2DoubleMap

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 Char2DoubleMap

Specified by:

keySet in interface Char2DoubleSortedMap

Specified by:

keySet in interface Map<Character,Double>

Overrides:

keySet in class Char2DoubleMaps.EmptyMap

Returns:

a set view of the keys contained in this map.

See Also:

Map.keySet()

subMap

public Char2DoubleSortedMap subMap(char from,
                                   char to)

Description copied from interface: Char2DoubleSortedMap

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

subMap in interface Char2DoubleSortedMap

See Also:

SortedMap.subMap(Object,Object)

headMap

public Char2DoubleSortedMap headMap(char to)

Description copied from interface: Char2DoubleSortedMap

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

Specified by:

See Also:

SortedMap.headMap(Object)

tailMap

public Char2DoubleSortedMap tailMap(char from)

Description copied from interface: Char2DoubleSortedMap

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

headMap

public Char2DoubleSortedMap headMap(Character oto)

Description copied from interface: Char2DoubleSortedMap

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 Char2DoubleSortedMap

tailMap

public Char2DoubleSortedMap tailMap(Character ofrom)

Description copied from interface: Char2DoubleSortedMap

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