Method Detail

comparator

public IntComparator comparator()

Description copied from interface: Int2IntSortedMap

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 Int2IntSortedMap

Specified by:

comparator in interface SortedMap<Integer,Integer>

See Also:

SortedMap.comparator()

int2IntEntrySet

public ObjectSortedSet<Int2IntMap.Entry> int2IntEntrySet()

Description copied from interface: Int2IntMap

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 Int2IntMap.entrySet() so that it returns an ObjectSet of objects of type Map.Entry (the latter makes it possible to access keys and values with type-specific methods).

Specified by:

int2IntEntrySet in interface Int2IntMap

Specified by:

int2IntEntrySet in interface Int2IntSortedMap

Overrides:

int2IntEntrySet in class Int2IntMaps.EmptyMap

Returns:

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

See Also:

Int2IntMap.entrySet()

entrySet

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

Description copied from interface: Int2IntMap

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 Int2IntMap

Specified by:

entrySet in interface Int2IntSortedMap

Specified by:

entrySet in interface Map<Integer,Integer>

Specified by:

entrySet in interface SortedMap<Integer,Integer>

Overrides:

entrySet in class Int2IntMaps.EmptyMap

Returns:

a set view of the mappings contained in this map.

See Also:

Map.entrySet()

keySet

public IntSortedSet keySet()

Description copied from interface: Int2IntMap

Returns a set view of the keys contained in this map.

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

Specified by:

keySet in interface Int2IntMap

Specified by:

keySet in interface Int2IntSortedMap

Specified by:

keySet in interface Map<Integer,Integer>

Specified by:

keySet in interface SortedMap<Integer,Integer>

Overrides:

keySet in class Int2IntMaps.EmptyMap

Returns:

a set view of the keys contained in this map.

See Also:

Map.keySet()

subMap

public Int2IntSortedMap subMap(int from,
                      int to)

Description copied from interface: Int2IntSortedMap
