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(java.lang.Object k)

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

public ObjectSet<Reference2IntMap.Entry<K>> reference2IntEntrySet()
Reference2IntMap
This method is necessary because there is no inheritance along
type parameters: it is thus impossible to strengthen Reference2IntMap.entrySet()
so that it returns an ObjectSet
of type-specific entries (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.
