Null value
val null : t
The null
value.
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
val wrap : t -> t option
wrap obj
wraps the reference
obj
into an option type:
Some x
if obj
is not null
;
None
if obj
is null
.
val unwrap : t option -> t
unwrap obj
unwraps the option
obj
into a bare reference:
Some x
