Method Details

comparator

public DoubleComparator comparator()

Description copied from interface: Double2ObjectSortedMap

Returns the comparator associated with this sorted set, or null if it uses its keys' natural ordering.

Specified by:

comparator in interface Double2ObjectSortedMap<V>

Specified by:

comparator in interface SortedMap<Double,V>

See Also:

• SortedMap.comparator()

double2ObjectEntrySet

public ObjectSortedSet<Double2ObjectMap.Entry<V>> double2ObjectEntrySet()

Description copied from interface: Double2ObjectMap

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:

double2ObjectEntrySet in interface Double2ObjectMap<V>

Specified by:

double2ObjectEntrySet in interface Double2ObjectSortedMap<V>

Overrides:

double2ObjectEntrySet in class Double2ObjectMaps.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.

Specified by:

entrySet in interface Double2ObjectMap<V>

Specified by:

entrySet in interface Double2ObjectSortedMap<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: Double2ObjectMap

Specified by:

keySet in interface Double2ObjectMap<V>

Specified by:

keySet in interface Double2ObjectSortedMap<V>

Specified by:

keySet in interface Map<Double,V>

Specified by:

keySet in interface SortedMap<Double,V>

Overrides:

keySet in class Double2ObjectMaps.EmptyMap<V>

Returns:

a set view of the keys contained in this map.

See Also:

• Map.keySet()

subMap

public Double2ObjectSortedMap<V> subMap(double from,
 double to)

Description copied from interface: Double2ObjectSortedMap

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

Specified by:

headMap

public Double2ObjectSortedMap<V> headMap(double to)

Description copied from interface: Double2ObjectSortedMap

See Also:

• SortedMap.headMap(Object)

tailMap

public Double2ObjectSortedMap<V> tailMap(double from)

Description copied from interface: Double2ObjectSortedMap
