Method Detail

headMap

public Reference2LongSortedMap<K> headMap(K to)
Delegates to the corresponding type-specific method.

Specified by:
headMap in interface Reference2LongSortedMap<K>
Specified by:
headMap in interface SortedMap<K,Long>
See Also:
SortedMap.headMap(Object)

tailMap

public Reference2LongSortedMap<K> tailMap(K from)
Delegates to the corresponding type-specific method.

Specified by:
tailMap in interface Reference2LongSortedMap<K>
Specified by:
tailMap in interface SortedMap<K,Long>
See Also:
SortedMap.tailMap(Object)

subMap

public Reference2LongSortedMap<K> subMap(K from,
                                         K to)
Delegates to the corresponding type-specific method.

Specified by:
subMap in interface Reference2LongSortedMap<K>
Specified by:
subMap in interface SortedMap<K,Long>
See Also:
SortedMap.subMap(Object,Object)

firstKey

public K firstKey()
Delegates to the corresponding type-specific method.

Specified by:
firstKey in interface SortedMap<K,Long>

lastKey

public K lastKey()
Delegates to the corresponding type-specific method.

Specified by:
lastKey in interface SortedMap<K,Long>

keySet

public ReferenceSortedSet<K> keySet()
Returns a type-specific-sorted-set view of the keys of this map.

The view is backed by the sorted set returned by entrySet(). Note that no attempt is made at caching the result of this method, as this would require adding some attributes that lightweight implementations would not need. Subclasses may easily override this policy by calling this method and caching the result, but implementors are encouraged to write more efficient ad-hoc implementations.

Specified by:
keySet in interface Reference2LongMap<K>
Specified by:
keySet in interface Reference2LongSortedMap<K>
Specified by:
keySet in interface Map<K,Long>
Specified by:
keySet in interface SortedMap<K,Long>
Overrides:
keySet in class AbstractReference2LongMap<K>
Returns:
a sorted set view of the keys of this map; it may be safely cast to a type-specific interface.
See Also:
Map.keySet()

values

public LongCollection values()
Returns a type-specific collection view of the values contained in this map.

The view is backed by the sorted set returned by entrySet(). Note that no attempt is made at caching the result of this method, as this would require adding some attributes that lightweight implementations would not need. Subclasses may easily override this policy by calling this method and caching the result, but implementors are encouraged to write more efficient ad-hoc implementations.

Specified by:
values in interface Reference2LongMap<K>
Specified by:
values in interface Reference2LongSortedMap<K>
Specified by:
values in interface Map<K,Long>
Specified by:
values in interface SortedMap<K,Long>
Overrides:
values in class AbstractReference2LongMap<K>
Returns:
a type-specific collection view of the values contained in this map.
See Also:
Map.values()

entrySet

public ObjectSortedSet<Map.Entry<K,Long>> entrySet()
Description copied from interface: Reference2LongMap
Returns a set view of the mappings contained in this map.

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

Specified by:
entrySet in interface Reference2LongMap<K>
Specified by:
entrySet in interface Reference2LongSortedMap<K>
Specified by:
entrySet in interface Map<K,Long>
Specified by:
entrySet in interface SortedMap<K,Long>
Overrides:
entrySet in class AbstractReference2LongMap<K>
Returns:
a set view of the mappings contained in this map.
