Bigarray.overlap
README
This little library allows us to check if to bigarray
share same memory area:
ba2
ba1 .-------.
.------|. |
| | | |
0x000800: [-------###-------]
| |
.
ba3
In this example, ba1
and ba2
share a small area and bigarray-overlap
can
returns this small area to you as a new ba3
value.
open Bigarray
let () =
let ba = Array1.create Char Bigarray.c_layout 17 in
let ba1 = Array1.sub ba 0 10 in
let ba2 = Array1.sub ba 7 17 in
match Overlap.array1 ba1 ba2 with
| Some (len, x, _y) ->
let ba3 = Array1.sub ba x len in
...
| None -> ...
overlap
returns the length of the shared area, the x
point from ba1
and
the y
point from ba2
.
A js_of_ocaml
support
overlap
is compatible with js_of_ocaml
but it lies about expected results.
Indeed, we are not able to know the position in memory of given bigarray
in
the JS world. By this fact, Overlap
with js_of_ocaml
will always returnsNone
.
