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 SortedMap<Long,Long>

Returns:

the comparator used to order the keys in this map, or null if this map uses the natural ordering of its keys

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<Map.Entry<Long,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 Map<Long,Long>

Specified by:

entrySet in interface SortedMap<Long,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

Returns a Set view of the keys contained in this map. The set is backed by the map, so changes to the map are reflected in the set, and vice-versa. If the map is modified while an iteration over the set is in progress (except through the iterator's own remove operation), the results of the iteration are undefined. The set supports element removal, which removes the corresponding mapping from the map, via the Iterator.remove, Set.remove, removeAll, retainAll, and clear operations. It does not support the add or addAll operations.

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 Map<Long,Long>

Specified by:

keySet in interface SortedMap<Long,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

See Also:

SortedMap.subMap(Object,Object)

headMap

public Long2LongSortedMap headMap(long to)

Description copied from interface: Long2LongSortedMap

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 Long2LongSortedMap

See Also:

SortedMap.headMap(Object)

tailMap

public Long2LongSortedMap tailMap(long from)

Description copied from interface: Long2LongSortedMap

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 Long2LongSortedMap

See Also:

SortedMap.tailMap(Object)

firstLongKey

public long firstLongKey()

Description copied from interface: Long2LongSortedMap

Returns the first (lowest) key currently in this map.

Specified by:

firstLongKey in interface Long2LongSortedMap

See Also:

SortedMap.firstKey()

lastLongKey

public long lastLongKey()

Description copied from interface: Long2LongSortedMap

Returns the last (highest) key currently in this map.

Specified by:

lastLongKey in interface Long2LongSortedMap

See Also:

SortedMap.lastKey()

headMap

@Deprecated
public Long2LongSortedMap headMap(Long oto)

Deprecated. Please use the corresponding type-specific method instead.

Returns a view of the portion of this map whose keys are strictly less than toKey. The returned map is backed by this map, so changes in the returned map are reflected in this map, and vice-versa. The returned map supports all optional map operations that this map supports.

The returned map will throw an IllegalArgumentException on an attempt to insert a key outside its range.

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

Specified by:

headMap in interface Long2LongSortedMap

Specified by:

headMap in interface SortedMap<Long,Long>

Parameters:

oto - high endpoint (exclusive) of the keys in the returned map

Returns:

a view of the portion of this map whose keys are strictly less than toKey

tailMap

@Deprecated
public Long2LongSortedMap tailMap(Long ofrom)

Deprecated. Please use the corresponding type-specific method instead.

Returns a view of the portion of this map whose keys are greater than or equal to fromKey. The returned map is backed by this map, so changes in the returned map are reflected in this map, and vice-versa. The returned map supports all optional map operations that this map supports.

The returned map will throw an IllegalArgumentException on an attempt to insert a key outside its range.

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

Specified by:

tailMap in interface Long2LongSortedMap

Specified by:

tailMap in interface SortedMap<Long,Long>

Parameters:

ofrom - low endpoint (inclusive) of the keys in the returned map

Returns:

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

Deprecated. Please use the corresponding type-specific method instead.

Returns a view of the portion of this map whose keys range from fromKey, inclusive, to toKey, exclusive. (If fromKey and toKey are equal, the returned map is empty.) The returned map is backed by this map, so changes in the returned map are reflected in this map, and vice-versa. The returned map supports all optional map operations that this map supports.

The returned map will throw an IllegalArgumentException on an attempt to insert a key outside its range.

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