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<Object2DoubleMap.Entry<K>> object2DoubleEntrySet()
Object2DoubleMap
This method is necessary because there is no inheritance along
type parameters: it is thus impossible to strengthen Object2DoubleMap.entrySet()
so that it returns an ObjectSet
of objects of type Object2DoubleMap.Entry
(the latter makes it possible to
access keys and values with type-specific methods).
