We distinguish three cases:
PathValid.NEVER
: there is no object of type
on which
path
can ever be defined.PathValid.ALWAYS
: if all intermediate objects are non-null, this
path
will always be defined on any object of type
. PathValid.POSSIBLE: some objects of type
will havepath
defined, while others may not.
