WARNING: physical comparison is used by the container.
CONSEQUENCE 1: should be used with caution to store int32
,
int64
, nativeint
, or double
values as they are wrapped into
blocks. Hence, comparisons are done on block addresses rather than
on wrapped values.
CONSEQUENCE 2: as OCaml-Java uses boxed values for int
values,
the container should not be used to store int
values.
Any other type can be safely stored (caching of some int
values
ensure that sum types are correctly handled).

int32
val make : int32 -> 'a -> 'a t
Raises Invalid_argument
if passed length is negative.
val compare_and_set : 'a t -> index -> 'a -> 'a -> bool
compare_and_set a i e u
atomically sets the value of a
at index
i
to u
if the current value is e
. Returns whether the value of
a
at index i
was equal to e
.
Raises Invalid_argument
if passed index is invalid.
val get : 'a t -> index -> 'a
Raises Invalid_argument
if passed index is invalid.
val get_and_set : 'a t -> index -> 'a -> 'a
get_and_set a i x
atomically sets the value of a
at index i
to
x
, and returns the previous value.
Raises Invalid_argument
if passed index is invalid.
val lazy_set : 'a t -> index -> 'a -> unit
lazy_set a i x
eventually sets the value of a
at index i
to
x
.
Raises Invalid_argument
if passed index is invalid.
val length : 'a t -> int32
val set : 'a t -> index -> 'a -> unit
set a i x
sets the value of a
at index i
to x
.
Raises Invalid_argument
if passed index is invalid.
val weak_compare_and_set : 'a t -> index -> 'a -> 'a -> bool
compare_and_set
, with a weak semantics: may be
faster on some platforms, but does not provide ordering guarantees.
Raises Invalid_argument
if passed index is invalid.
