public int size()
Function
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<Double2ReferenceMap.Entry<V>> double2ReferenceEntrySet()
Double2ReferenceMap
This method is necessary because there is no inheritance along
type parameters: it is thus impossible to strengthen Double2ReferenceMap.entrySet()
so that it returns an ObjectSet
of objects of type Double2ReferenceMap.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.
