public interface Reference2DoubleSortedMap<K>
extends Reference2DoubleMap<K>, java.util.SortedMap<K,java.lang.Double>

A type-specific SortedMap; provides some additional methods that use polymorphism to avoid (un)boxing.

Additionally, this interface strengthens entrySet(), keySet(), values(), comparator(), SortedMap.subMap(Object,Object), SortedMap.headMap(Object) and SortedMap.tailMap(Object).

Method Detail

entrySet

ObjectSortedSet<java.util.Map.Entry<K,java.lang.Double>> entrySet()
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 java.util.Map<K,java.lang.Double>
Specified by:
entrySet in interface Reference2DoubleMap<K>
Returns:
a sorted-set view of the mappings contained in this map.
See Also:
Map.entrySet()

reference2DoubleEntrySet

ObjectSortedSet<Reference2DoubleMap.Entry<K>> reference2DoubleEntrySet()
Returns a type-specific 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:
reference2DoubleEntrySet in interface Reference2DoubleMap<K>
Returns:
a type-specific sorted-set view of the mappings contained in this map.
See Also:
entrySet()

keySet

ReferenceSortedSet<K> keySet()
Returns a sorted-set view of the keys contained in this map. Note that this specification strengthens the one given in the corresponding type-specific unsorted map.

Specified by:
keySet in interface java.util.Map<K,java.lang.Double>
Specified by:
keySet in interface Reference2DoubleMap<K>
Returns:
a sorted-set view of the keys contained in this map.
See Also:
Map.keySet()

values

DoubleCollection values()
Returns a set view of the values contained in this map.

Note that this specification strengthens the one given in Map.values(), which was already strengthened in the corresponding type-specific class, but was weakened by the fact that this interface extends SortedMap.

Specified by:
values in interface java.util.Map<K,java.lang.Double>
Specified by:
values in interface Reference2DoubleMap<K>
Returns:
a set view of the values contained in this map.
See Also:
Map.values()

comparator

java.util.Comparator<? super K> comparator()
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 java.util.SortedMap<K,java.lang.Double>
See Also:
SortedMap.comparator()

subMap

Reference2DoubleSortedMap<K> subMap(K fromKey,
                                    K toKey)
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 java.util.SortedMap<K,java.lang.Double>
See Also:
SortedMap.subMap(Object,Object)

headMap

Reference2DoubleSortedMap<K> headMap(K toKey)
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 java.util.SortedMap<K,java.lang.Double>
See Also:
SortedMap.headMap(Object)

tailMap

Reference2DoubleSortedMap<K> tailMap(K fromKey)
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 java.util.SortedMap<K,java.lang.Double>
See Also:
SortedMap.tailMap(Object)
