public int size()

Most function implementations will have some knowledge of the intended number of keys in their domain. In some cases, however, this might not be possible.

public ObjectSet<Float2LongMap.Entry> float2LongEntrySet()
Float2LongMap
This method is necessary because there is no inheritance along
type parameters: it is thus impossible to strengthen Float2LongMap.entrySet()
so that it returns an ObjectSet
of objects of type Float2LongMap.Entry
(the latter makes it possible to
access keys and values with type-specific methods).

This method must check whether the provided key is in the map using containsKey()
. Thus,
it probes the map twice. Implementors of subclasses should override it with a more efficient method.
