Object2IntMap
This method is necessary because there is no inheritance along
type parameters: it is thus impossible to strengthen Map.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).

Note that contrarily to the default computeIfAbsent(),
it is not possible to not add a value for a given key, since the mappingFunction
cannot
return null
. If such a behavior is needed, please use the corresponding nullable version.

This version of computeIfAbsent()

Since Function
has a containsKey()
method, it is possible to avoid adding a key by having containsKey()
return false
for that key.

If the function returns null

If the function itself throws an (unchecked) exception, the exception is rethrown, and the current mapping is left unchanged.
