Method Detail

comparator

public LongComparator comparator()

Description copied from interface: Long2LongSortedMap

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 Long2LongSortedMap

Specified by:

comparator in interface java.util.SortedMap<java.lang.Long,java.lang.Long>

See Also:

SortedMap.comparator()

long2LongEntrySet

public ObjectSortedSet<Long2LongMap.Entry> long2LongEntrySet()

Description copied from interface: Long2LongMap

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:

long2LongEntrySet in interface Long2LongMap

Specified by:

long2LongEntrySet in interface Long2LongSortedMap

Overrides:

long2LongEntrySet in class Long2LongMaps.EmptyMap

Returns:

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

See Also:

Map.entrySet()

entrySet

@Deprecated
public ObjectSortedSet<java.util.Map.Entry<java.lang.Long,java.lang.Long>> 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 Long2LongMap

Specified by:

entrySet in interface Long2LongSortedMap

Specified by:

entrySet in interface java.util.Map<java.lang.Long,java.lang.Long>

Specified by:

entrySet in interface java.util.SortedMap<java.lang.Long,java.lang.Long>

Returns:

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

See Also:

SortedMap.entrySet()

keySet

public LongSortedSet keySet()

Description copied from interface: Long2LongMap

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

Specified by:

keySet in interface Long2LongMap

Specified by:

keySet in interface Long2LongSortedMap

Specified by:

keySet in interface java.util.Map<java.lang.Long,java.lang.Long>

Specified by:

keySet in interface java.util.SortedMap<java.lang.Long,java.lang.Long>

Overrides:

keySet in class Long2LongMaps.EmptyMap

Returns:

a set view of the keys contained in this map.

See Also:

Map.keySet()

subMap

public Long2LongSortedMap subMap(long from,
                                 long to)

Description copied from interface: Long2LongSortedMap

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 Long2LongSortedMap

SortedMap.subMap(Object,Object)

headMap

public Long2LongSortedMap headMap(long to)

Description copied from interface: Long2LongSortedMap
