Method Detail

headMap

public Long2LongSortedMap headMap(Long to)

Delegates to the corresponding type-specific method.

Specified by:

headMap in interface Long2LongSortedMap

Specified by:

headMap in interface SortedMap<Long,Long>

See Also:

SortedMap.headMap(Object)

tailMap

public Long2LongSortedMap tailMap(Long from)

Delegates to the corresponding type-specific method.

Specified by:

tailMap in interface Long2LongSortedMap

Specified by:

tailMap in interface SortedMap<Long,Long>

See Also:

SortedMap.tailMap(Object)

subMap

public Long2LongSortedMap subMap(Long from,
                                 Long to)

Delegates to the corresponding type-specific method.

Specified by:

subMap in interface Long2LongSortedMap

Specified by:

subMap in interface SortedMap<Long,Long>

See Also:

SortedMap.subMap(Object,Object)

firstKey

public Long firstKey()

Delegates to the corresponding type-specific method.

Specified by:

firstKey in interface SortedMap<Long,Long>

lastKey

public Long lastKey()

Delegates to the corresponding type-specific method.

Specified by:

lastKey in interface SortedMap<Long,Long>

keySet

public LongSortedSet 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 Long2LongMap

Specified by:

keySet in interface Long2LongSortedMap

Specified by:

keySet in interface Map<Long,Long>

Overrides:

keySet in class AbstractLong2LongMap

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 Long2LongMap

Specified by:

values in interface Long2LongSortedMap

Specified by:

values in interface Map<Long,Long>

Overrides:

values in class AbstractLong2LongMap

Returns:

a type-specific collection view of the values contained in this map.

See Also:

Map.values()

entrySet

public ObjectSortedSet<Map.Entry<Long,Long>> entrySet()

Description copied from interface: Long2LongMap

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 Long2LongMap

Specified by:

entrySet in interface Long2LongSortedMap

Specified by:

entrySet in interface Map<Long,Long>

Overrides:

entrySet in class AbstractLong2LongMap

Returns:

a set view of the mappings contained in this map.
