Vector
Provide vector utilities.
t
REStype t<'a> = array<'a>
filterInPlace
RESlet filterInPlace: ((. 'a) => bool, t<'a>) => unit
p : predicate a : array
empty
RESlet empty: t<'a> => unit
pushBack
RESlet pushBack: ('a, t<'a>) => unit
copy
RESlet copy: t<'a> => t<'a>
Create a shallow copy of a vector.
memByRef
RESlet memByRef: ('a, t<'a>) => bool
Find by JS (===) equality.
iter
RESlet iter: ((. 'a) => unit, t<'a>) => unit
iteri
RESlet iteri: ((. int, 'a) => unit, t<'a>) => unit
toList
RESlet toList: t<'a> => list<'a>
map
RESlet map: ((. 'a) => 'b, t<'a>) => t<'b>
mapi
RESlet mapi: ((. int, 'a) => 'b, t<'a>) => t<'b>
foldLeft
RESlet foldLeft: ((. 'a, 'b) => 'a, 'a, t<'b>) => 'a
foldRight
RESlet foldRight: ((. 'b, 'a) => 'a, t<'b>, 'a) => 'a
length
RESlet length: t<'a> => int
Return the length (number of elements) of the given array.
get
RESlet get: (t<'a>, int) => 'a
Vector.get(a, n) returns the element number n of vector a. The first element has number 0. The last element has number Vector.length(a) - 1. You can also write a[n] instead of Vector.get(a, n).
Raise Invalid_argument "index out of bounds" if n is outside the range 0 to (Array.length(a) - 1).
set
RESlet set: (t<'a>, int, 'a) => unit
Vector.set(a, n, x) modifies vector a in place, replacing element number n with x.
Raise Invalid_argument "index out of bounds" if n is outside the range 0 to Array.length(a) - 1.
make
RESlet make: (int, 'a) => t<'a>
Vector.make(n, x) returns a fresh vector of length n, initialized with x. All the elements of this new vector are initially physically equal to x (in the sense of the == predicate).
Consequently, if x is mutable, it is shared among all elements of the array, and modifying x through one of the array entries will modify all other entries at the same time.
Raise Invalid_argument if n < 0 or n > Sys.max_array_length. If the value of x is a floating-point number, then the maximum size is only Sys.max_array_length / 2.
init
RESlet init: (int, (. int) => 'a) => t<'a>
Raises RangeError when n is negative.
n : size
append
RESlet append: ('a, t<'a>) => t<'a>
append(x, a) returns a fresh vector with x appended to a.
unsafe_get
RESlet unsafe_get: (t<'a>, int) => 'a
unsafe_set
RESlet unsafe_set: (t<'a>, int, 'a) => unit
