Method Details

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.

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 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:

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:

• Map.entrySet()

entrySet

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

Deprecated.

Please use the corresponding type-specific method instead.

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

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>

Returns:

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

See Also:

• SortedMap.entrySet()

keySet

public DoubleSortedSet keySet()

Description copied from interface: Double2DoubleMap

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

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

Specified by:

subMap in interface Double2DoubleSortedMap

See Also:

• SortedMap.subMap(Object,Object)

headMap

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.

Specified by:

See Also:

• SortedMap.headMap(Object)

tailMap

public Double2DoubleSortedMap tailMap(double from)

Description copied from interface: Double2DoubleSortedMap

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

Specified by:

See Also:

• SortedMap.tailMap(Object)

firstDoubleKey

public double firstDoubleKey()

Description copied from interface: Double2DoubleSortedMap
