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 boolean containsKey(Object k)

Note that for some kind of functions (e.g., hashes) this method will always return true.

public ObjectSet<Object2CharMap.Entry<K>> object2CharEntrySet()
Object2CharMap
This method is necessary because there is no inheritance along
type parameters: it is thus impossible to strengthen Object2CharMap.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).
