create ~sep ~dimension_names ~attributes ~codecs ~shape ~chunks kind fill node t
creates an array node in store t
where:
sep
is used in the array's chunk key encoding.dimension_names
and user attributes attributes
are included in it's metadata document.codecs
.shape
and chunk shape chunks
.kind
and fill value fv
.val metadata : t -> Node.Array.t -> Metadata.Array.t Deferred.t
metadata node t
returns the metadata of array node node
.
val delete : t -> Node.Array.t -> unit Deferred.t
delete t n
erases array node n
from store t
. If node n
is not a member of store t
then this is a no-op.
val exists : t -> Node.Array.t -> bool Deferred.t
exists t n
returns true
if array node n
is a member of store t
and false
otherwise.
val write :
t ->
Node.Array.t ->
Ndarray.Indexing.index array ->
'a Ndarray.t ->
unit Deferred.t
write t n s x
writes n-dimensional array x
to the slice s
of array node n
in store t
.
val read :
t ->
Node.Array.t ->
Ndarray.Indexing.index array ->
'a Ndarray.dtype ->
'a Ndarray.t Deferred.t
read t n s k
reads an n-dimensional array of size determined by slice s
from array node n
.
val reshape : t -> Node.Array.t -> int array -> unit Deferred.t
reshape t n shape
resizes array node n
of store t
into new size shape
.
val rename : t -> Node.Array.t -> string -> unit Deferred.t
rename t n name
changes the name of array node n
in store t
to name
.
