Method Detail

comparator

public DoubleComparator comparator()

Description copied from interface: Double2ReferenceSortedMap

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 Double2ReferenceSortedMap<V>

Specified by:

comparator in interface SortedMap<Double,V>

See Also:

SortedMap.comparator()

double2ReferenceEntrySet

public ObjectSortedSet<Double2ReferenceMap.Entry<V>> double2ReferenceEntrySet()

Description copied from interface: Double2ReferenceMap

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

Specified by:

double2ReferenceEntrySet in interface Double2ReferenceMap<V>

Specified by:

double2ReferenceEntrySet in interface Double2ReferenceSortedMap<V>

Overrides:

double2ReferenceEntrySet in class Double2ReferenceMaps.EmptyMap<V>

Returns:

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

See Also:

Map.entrySet()

entrySet

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

Deprecated. Please use the corresponding type-specific method instead.

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

Note that this specification strengthens the one given in the corresponding type-specific unsorted map.

Specified by:

entrySet in interface Double2ReferenceMap<V>

Specified by:

entrySet in interface Double2ReferenceSortedMap<V>

Specified by:

entrySet in interface Map<Double,V>

Specified by:

entrySet in interface SortedMap<Double,V>

Returns:

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

See Also:

SortedMap.entrySet()

keySet

public DoubleSortedSet keySet()

Description copied from interface: Double2ReferenceMap

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

Specified by:

keySet in interface Double2ReferenceMap<V>

Specified by:

keySet in interface Double2ReferenceSortedMap<V>

Specified by:

keySet in interface Map<Double,V>

Specified by:

keySet in interface SortedMap<Double,V>

Overrides:

keySet in class Double2ReferenceMaps.EmptyMap<V>

Returns:

a set view of the keys contained in this map.

                                           double to)

Description copied from interface: Double2ReferenceSortedMap

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