module AtomicInt64Array: sig .. end
Atomic containers for arrays of int64 values.
type index = int32
The type of array indices.
val make : int32 -> t
Returns a new container holding an array of passed length.
Raises Java_error if passed length is negative
val add_and_get : t -> index -> int64 -> int64
add_and_get a i d atomically adds d to the value at index i,
and returns the new value.
Raises Java_error if passed index is invalid
val compare_and_set : t -> index -> int64 -> int64 -> 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 Java_error if passed index is invalid
val decrement_and_get : t -> index -> int64
Atomically decrements the value at passed index, and returns the new
value.
Raises Java_error if passed index is invalid
val get : t -> index -> int64
Returns the value at passed index.
Raises Java_error if passed index is invalid
val get_and_add : t -> index -> int64 -> int64
get_and_add a i d atomically adds d to the value at index i,
and returns the previous value.
Raises Java_error if passed index is invalid
val get_and_decrement : t -> index -> int64
Atomically decrements the value at passed index, and returns the
previous value.
Raises Java_error if passed index is invalid
val get_and_increment : t -> index -> int64
Atomically increments the value at passed index, and returns the
previous value.
Raises Java_error if passed index is invalid
val get_and_set : t -> index -> int64 -> int64
get_and_set a i x atomically sets the value of a at index i to
x, and returns the previous value.
Raises Java_error if passed index is invalid
val increment_and_get : t -> index -> int64
Atomically increments the value at passed index, and returns the new
value.
Raises Java_error if passed index is invalid
val lazy_set : t -> index -> int64 -> unit
lazy_set a i x eventually sets the value of a at index i to
x.
Raises Java_error if passed index is invalid
val length : t -> int32
Returns the length of the array.
val set : t -> index -> int64 -> unit
set a i x sets the value of a at index i to x.
Raises Java_error if passed index is invalid
val weak_compare_and_set : t -> index -> int64 -> int64 -> bool
Similar to
AtomicInt64Array.compare_and_set, with a
weak semantics: may be
faster on some platforms, but does not provide ordering guarantees.
Raises Java_error if passed index is invalid
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 is mapped to x;None is mapped to null.
