Method Detail

comparator

public DoubleComparator comparator()

Description copied from interface: Double2DoubleSortedMap

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 Double2DoubleSortedMap

Specified by:

comparator in interface SortedMap<Double,Double>

See Also:

SortedMap.comparator()

double2DoubleEntrySet

public ObjectSortedSet<Double2DoubleMap.Entry> double2DoubleEntrySet()

Description copied from interface: Double2DoubleMap

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 Double2DoubleMap.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:

double2DoubleEntrySet in interface Double2DoubleMap

Specified by:

double2DoubleEntrySet in interface Double2DoubleSortedMap

Overrides:

double2DoubleEntrySet in class Double2DoubleMaps.EmptyMap

Returns:

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

See Also:

Double2DoubleMap.entrySet()

entrySet

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

Description copied from interface: Double2DoubleMap

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 Double2DoubleMap

Specified by:

entrySet in interface Double2DoubleSortedMap

Specified by:

entrySet in interface Map<Double,Double>

Specified by:

entrySet in interface SortedMap<Double,Double>

Overrides:

entrySet in class Double2DoubleMaps.EmptyMap

Returns:

a set view of the mappings contained in this map.

See Also:

Map.entrySet()

keySet

public DoubleSortedSet keySet()

Description copied from interface: Double2DoubleMap

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 Double2DoubleMap

Specified by:

keySet in interface Double2DoubleSortedMap

Specified by:

keySet in interface Map<Double,Double>

Specified by:

keySet in interface SortedMap<Double,Double>

Overrides:

keySet in class Double2DoubleMaps.EmptyMap

Returns:

a set view of the keys contained in this map.

See Also:

Map.keySet()

subMap

public Double2DoubleSortedMap subMap(double from,
                            double to)

Description copied from interface: Double2DoubleSortedMap

public Double2DoubleSortedMap headMap(double to)

Description copied from interface: Double2DoubleSortedMap

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

headMap

public Double2DoubleSortedMap headMap(Double oto)

Description copied from interface: Double2DoubleSortedMap

tailMap

public Double2DoubleSortedMap tailMap(Double ofrom)
