module JavaLongArray: sig .. end
Support for long[] type.

type e = java_long
The type of array elements.
 
type 'a t = 'a java_long_array
The type of arrays.
 

Usual operations

 
val make : java_int -> e java_long_array
make len creates and returns an array of len elements. All elements are set to zero.
Raises Java_exception if len is negative
 
val init : java_int -> (java_int -> e) -> e java_long_array
init len f creates and returns an array of len elements. The element at index i is initialized with value f i.
Raises Java_exception if len is negative
 
val length : e java_long_array -> java_int
length a returns the length of a.
Raises Java_exception if a is null
 
val get : e java_long_array -> java_int -> 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_long_array -> java_int -> 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_long_array ->
e java_long_array -> e java_long_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_long_array list -> e java_long_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_long_array ->
java_int -> java_int -> e java_long_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_long_array -> e java_long_array
copy a returns a copy of a.
Raises Java_exception if a is null
 
val fill : e java_long_array ->
java_int -> java_int -> 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_long_array ->
java_int -> e java_long_array -> java_int -> java_int -> 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_long_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_long_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 java_int value
 
val iter : (e -> unit) -> e java_long_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_long_array -> e java_long_array
map f a returns an array with elements 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 : (java_int -> e -> unit) ->
e java_long_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 : (java_int -> e -> e) ->
e java_long_array -> e java_long_array
map f a returns an array with elements 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_long_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_long_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_long_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 java_int value
 
val to_ocaml : e java_long_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_long_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_long_array
of_object o casts object o to array.
Raises Java_exception if cast fails
 
val equals : e java_long_array -> e java_long_array -> bool
equals a1 a2 tests whether a1 and a2 are equal; see equals(...).
 
val hash_code : e java_long_array -> java_int
hash_code a returns the hash code of a; see hashCode(...).
 
val to_string : e java_long_array -> JavaString.t
to_string a returns the string representation of a; see toString(...).
 
val null : e java_long_array
The null value.
 
val is_null : e java_long_array -> bool
is_null x returns true iff x is equal to null.
 
val is_not_null : e java_long_array -> bool
is_not_null x returns false iff x is equal to null.
 
val wrap : e java_long_array -> e java_long_array option
wrap x wraps the array x into an option type:
  • Some x if x is not null;
  • None if x is null.

 
val unwrap : e java_long_array option -> e java_long_array
unwrap x unwraps the option x into a bare reference:
  • Some x is mapped to x;
  • None is mapped to null.
