Format to the output stream supplied at construction the object at the specified `address`, if `address` is not 0, and print the string "NULL" otherwise, prefixed by the specified `name` if `name` is not 0. If `spacesPerLevel() < 0`, print on a single line. If `spacesPerLevel() >= 0`, indent by `(absLevel() + 1) * spacesPerLevel()` blank spaces. The behavior is undefined unless `TYPE` is a pointer type.
