Interface Long2IntMap

All Superinterfaces:

LongMap<Integer>

All Known Implementing Classes:

AbstractLong2IntMap, Long2IntOpenHashMap

public interface Long2IntMap
extends LongMap<Integer>

A type-specific Map; provides some additional methods that use polymorphism to avoid (un)boxing, and handling of a default return value.

Besides extending the corresponding type-specific function, this interface strengthens entrySet(), keySet() and values(). Maps returning entry sets of type Long2IntMap.FastEntrySet support also fast iteration.

A submap or subset may or may not have an independent default return value (which however must be initialized to the default return value of the originator).

Method Detail

entrySet

it.unimi.dsi.fastutil.objects.ObjectSet<LongMap.Entry<Integer>> entrySet()

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 LongMap<Integer>

Returns:

a set view of the mappings contained in this map.

See Also:

Map.entrySet()

long2IntEntrySet

it.unimi.dsi.fastutil.objects.ObjectSet<LongMap.Entry> long2IntEntrySet()

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 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).

Returns:

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

See Also:

entrySet()

keySet

it.unimi.dsi.fastutil.longs.LongSet keySet()

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 LongMap<Integer>

Returns:

a set view of the keys contained in this map.

See Also:

Map.keySet()

values

it.unimi.dsi.fastutil.ints.IntCollection values()

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

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

Specified by:

values in interface LongMap<Integer>

Returns:

a set view of the values contained in this map.

Map.values()
