java.text.SimpleDateFormat.
Raises Java_exception if the pattern is invalid

val is_null : t -> bool
is_null obj returns true iff obj is equal to null.
val is_not_null : t -> bool
is_not_null obj returns false iff obj is equal to null.
Miscellaneous

wrap obj wraps the reference
obj into an option type:

val unwrap : t option -> t
unwrap obj unwraps the option
obj into a bare reference:
Some x is mapped to x;None is mapped to null.
