Method Detail

comparator

public DoubleComparator comparator()

Description copied from interface: Double2LongSortedMap

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 Double2LongSortedMap

Specified by:

comparator in interface SortedMap<Double,Long>

See Also:

SortedMap.comparator()

double2LongEntrySet

public ObjectSortedSet<Double2LongMap.Entry> double2LongEntrySet()

Description copied from interface: Double2LongMap

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 Double2LongMap.entrySet() so that it returns an ObjectSet of objects of type Double2LongMap.Entry (the latter makes it possible to access keys and values with type-specific methods).

Specified by:

double2LongEntrySet in interface Double2LongMap

Specified by:

double2LongEntrySet in interface Double2LongSortedMap

Overrides:

double2LongEntrySet in class Double2LongMaps.EmptyMap

Returns:

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

See Also:

Double2LongMap.entrySet()

entrySet

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

Description copied from interface: Double2LongMap

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 Double2LongMap

Specified by:

entrySet in interface Double2LongSortedMap

Specified by:

entrySet in interface Map<Double,Long>

Overrides:

entrySet in class Double2LongMaps.EmptyMap

Returns:

a set view of the mappings contained in this map.

See Also:

Map.entrySet()

keySet

public DoubleSortedSet keySet()

Description copied from interface: Double2LongMap

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 Double2LongMap

Specified by:

keySet in interface Double2LongSortedMap

Specified by:

keySet in interface Map<Double,Long>

Overrides:

keySet in class Double2LongMaps.EmptyMap

Returns:

a set view of the keys contained in this map.

See Also:

Map.keySet()

subMap

public Double2LongSortedMap subMap(double from,
                                   double to)

Description copied from interface: Double2LongSortedMap

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

SortedMap.subMap(Object,Object)

headMap

public Double2LongSortedMap headMap(double to)

Description copied from interface: Double2LongSortedMap

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 Double2LongSortedMap tailMap(double from)

Description copied from interface: Double2LongSortedMap

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

headMap

public Double2LongSortedMap headMap(Double oto)

Description copied from interface: Double2LongSortedMap

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 Double2LongSortedMap

Specified by:

headMap in interface SortedMap<Double,Long>

tailMap

public Double2LongSortedMap tailMap(Double ofrom)

Description copied from interface: Double2LongSortedMap

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