public interface Byte2LongMap extends Byte2LongFunction, Map<Byte,Long>
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 Byte2LongMap.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).

ObjectSet<Map.Entry<Byte,Long>> entrySet()
Note that this specification strengthens the one given in Map.entrySet()
.
entrySet
in interface Map<Byte,Long>
Map.entrySet()
ObjectSet<Byte2LongMap.Entry> byte2LongEntrySet()
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).
