Method Details

comparator

public Comparator<? super K> comparator()

Description copied from interface: Object2DoubleSortedMap

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 Object2DoubleSortedMap<K>

Specified by:

comparator in interface SortedMap<K,Double>

See Also:

SortedMap.comparator()

object2DoubleEntrySet

public ObjectSortedSet<Object2DoubleMap.Entry<K>> object2DoubleEntrySet()

Description copied from interface: Object2DoubleMap

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:

object2DoubleEntrySet in interface Object2DoubleMap<K>

Specified by:

object2DoubleEntrySet in interface Object2DoubleSortedMap<K>

Overrides:

object2DoubleEntrySet in class Object2DoubleMaps.EmptyMap<K>

Returns:

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

See Also:

Map.entrySet()

entrySet

@Deprecated
public ObjectSortedSet<Map.Entry<K,Double>> 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 Map<K,Double>

Specified by:

entrySet in interface Object2DoubleMap<K>

Specified by:

entrySet in interface Object2DoubleSortedMap<K>

Specified by:

entrySet in interface SortedMap<K,Double>

Returns:

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

See Also:

SortedMap.entrySet()

keySet

public ObjectSortedSet<K> keySet()

Description copied from interface: Object2DoubleMap

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

Specified by:

keySet in interface Map<K,Double>

Specified by:

keySet in interface Object2DoubleMap<K>

Specified by:

keySet in interface Object2DoubleSortedMap<K>

Specified by:

keySet in interface SortedMap<K,Double>

Overrides:

keySet in class Object2DoubleMaps.EmptyMap<K>

Returns:

a set view of the keys contained in this map.

See Also:

Map.keySet()

subMap

public Object2DoubleSortedMap<K> subMap(K from,
K to)

Description copied from interface: Object2DoubleSortedMap

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

Note that this specification strengthens the one given in SortedMap.subMap(Object,Object).

Specified by:

subMap in interface Object2DoubleSortedMap<K>

Specified by:

subMap in interface SortedMap<K,Double>

See Also:

SortedMap.subMap(Object,Object)

headMap

public Object2DoubleSortedMap<K> headMap(K to)

Description copied from interface: Object2DoubleSortedMap

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 Object2DoubleSortedMap<K>

Specified by:

headMap in interface SortedMap<K,Double>

See Also:

SortedMap.headMap(Object)

tailMap

public Object2DoubleSortedMap<K> tailMap(K from)

Description copied from interface: Object2DoubleSortedMap

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

Note that this specification strengthens the one given in SortedMap.tailMap(Object).

Specified by:

tailMap in interface Object2DoubleSortedMap<K>

Specified by:

tailMap in interface SortedMap<K,Double>
