Usual operations
val make : int32 -> e java_float_array
make len
creates and returns an array of len

creates and returns an array of len
elements.
The element at index i
is initialized with value f i
.

if len
is negative.
val length : e java_float_array -> int32
length a
returns the length of a
.
Raises Java_exception
if a
is null.
val get : e java_float_array -> int32 -> e
get a i
returns the element at index i
in a
.
Raises Java_exception
if a
is null, or i
is out of bounds.
val set : e java_float_array -> int32 -> e -> unit
set a i x
changes the element at index i
in a
to x
.
Raises Java_exception
if a
is null, or i
is out of bounds.
val append : e java_float_array ->
e java_float_array -> e java_float_array
append a1 a2
returns the concatenation of a1
and a2
.
Raises Java_exception
if either a1
or a2
is null.
val concat : e java_float_array list -> e java_float_array
concat l
returns the concatenation of arrays in l
.
Raises Java_exception
if any of the arrays in l
is null.
val sub : e java_float_array ->
int32 -> int32 -> e java_float_array
sub a ofs len
returns an array of len
elements, copying elements
from a
starting at offset ofs
.
Raises Java_exception
if a
is null.
val copy : e java_float_array -> e java_float_array
copy a
returns a copy of a
.
Raises Java_exception
if a
is null.
val fill : e java_float_array ->
int32 -> int32 -> e -> unit
fill a ofs len x
sets len
elements of a
to x
, starting at
offset ofs
.
Raises Java_exception
if a
is null.
val blit : e java_float_array ->
int32 -> e java_float_array -> int32 -> int32 -> unit
blit src srcofs dst dstofs len
copies len
elements from src
at
offset srcofs
to dst
at offset dstofs
.
Raises Java_exception
if either src
or ofs
is null.
val to_list : e java_float_array -> e list
to_list a
returns the elements of a
as a list.
Raises Java_exception
if a
is null.
val of_list : e list -> e java_float_array
of_list l
returns the elements of l
as an array.
Raises Invalid_argument
if l
has more elements than can be
represented by an int32
value.
val iter : (e -> unit) -> e java_float_array -> unit
iter f a
applies f
to each element of a
.
Raises Java_exception
if a
is null.
val map : (e -> e) ->
e java_float_array -> e java_float_array
map f a
returns an array with elemens f a_0, f a_1, ...
where
a_i
is the element of a
at index i
.
Raises Java_exception
if a
is null.
val iteri : (int32 -> e -> unit) ->
e java_float_array -> unit
iter f a
applies f
to each element of a
(also passing element index).
Raises Java_exception
if a
is null.
val mapi : (int32 -> e -> e) ->
e java_float_array -> e java_float_array
map f a
returns an array with elemens f 0 a_0, f 1 a_1, ...
where
a_i
is the element of a
at index i
.
Raises Java_exception
if a
is null.
val fold_left : ('a -> e -> 'a) ->
'a -> e java_float_array -> 'a
fold_left f z a
returns f (... (f (f z a_0) a_1))
where a_i
is
the element of a
at index i
.
Raises Java_exception
if a
is null.
val fold_right : (e -> 'a -> 'a) ->
e java_float_array -> 'a -> 'a
fold_right f a z
returns f a_0 (f a_1 (f ... z))
where a_i
is
the element of a
at index i
.
Raises Java_exception
if a
is null.
Conversion from/to OCaml arrays
val of_ocaml : e array -> e java_float_array
of_ocaml a
returns a Java array equivalent to a
.
Raises Invalid_argument
if a
has more elements than can be
represented by an int32
value.
val to_ocaml : e java_float_array -> e array
to_ocaml a
returns an OCaml array equivalent to a
.
Raises Java_exception
if a
is null.
Java operations
val to_object : e java_float_array -> java'lang'Object java_instance
to_object a
casts a
to a bare object.
val of_object : java'lang'Object java_instance -> e java_float_array
of_object o
casts object o
to array.
Raises Java_exception
if cast fails.
val null : e java_float_array
The null value.
val is_null : e java_float_array -> bool
is_null x
returns true
iff x
is equal to null.
val is_not_null : e java_float_array -> bool
is_not_null x
returns false
iff x
is equal to null.
val wrap : e java_float_array -> e java_float_array option
wrap x
wraps the array
x
into an option type:
Some x
if x
is not null;
None
if x
is null.
