FunctionMost function implementations will have some knowledge of the intended number of keys in their domain. In some cases, however, this might not be possible. This default implementation, in particular, returns -1.
public int defaultReturnValue()
Reference2IntFunctionThis default implementation just return the default null value
of the type (null for objects, 0 for scalars, false for Booleans).

Reference2IntFunctionget(), put() and remove() to
denote that the map does not contain the specified key. It must be

FunctionNote that for some kind of functions (e.g., hashes) this method will always return true. This default implementation, in particular, always return true.
