Int32Array : ArrayBufferView
Array
where each item is a 32 bit (4 byte) signed integer. Int32Arrays cannot change size after creation.Constructors
Creates a new Int32Array
and copies the items of array
into this
. The copied items are converted to 32 bit integers before being stored in this
.
Example:
RunResults:
Creates a new Int32Array
and copies the items of array
into this
. array
can be any of the typed array types and the copied items will be converted to 32 bit integers before being stored in this
.
Example:
RunResults:
Creates a view on top of the specified buffer
starting at byteOffset
of length
items. Changes to the items in this
actual affect the underlying buffer
, and vice versa. byteOffset
must be a multiple of 4. (Use DataView
for unaligned data.) If length
is not specified, buffer.length - byteOffset
must be a multiple of 4 and this.length
will be (buffer.length - byteOffset) / 4
.
Example:
RunResults:
Instance Indexers
Gets and sets the element in this
at index
. index
should be between 0
and this.length - 1
.
Example:
RunResults:
Instance Methods
Copies this[start]
, this[start + 1]
, ... this[end - 1]
to this[target]
, this[target + 1]
, ... If end
is not specified, this.length
is used.
Example:
RunResults:
Returns true
if callback
returns true
for every item in this
. Otherwise returns false
. The Int32Array
passed to callback
is the this
of the call to every
.
Example:
RunResults:
Fills this[start]
, this[start + 1]
, ... this[end - 1]
with value
. If end
is not specified, this.length
is used. Returns this
.
Example:
RunResults:
Returns a new Int32Array
containing only the items in this
that callback
returned true
for. The Int32Array
passed to callback
is the this
of the call to filter
.
Example:
RunResults:
Returns the first item in this
where callback
returns true
for that item. The Int32Array
passed to callback
is the this
of the call to find
. See also findIndex()
.
Example:
RunResults:
Calls callback
for each item in this
. The Int32Array
passed to callback
is the this
of the call to forEach
.
Example:
RunResults:
Returns true
if item
is an element of this
starting the search from startingIndex
. If startingIndex
is negative, this.length
is added to it before starting the search.
Example:
RunResults:
Returns the first location of item
in this
starting the search from start
. If startingIndex
is negative, this.length
is added to it before starting the search. Returns -1
if item
is not found. See also lastIndexOf()
.
Example:
RunResults:
Returns a String created by joining the toString()
of each item of this
separated by separator
.
Example:
RunResults:
Returns the location of item
by searchig backwards through this
, starting the search from startingIndex
. If startingIndex
is not specified, the search starts from the end of the array. If startingIndex
is negative, this.length
is added to it before starting the search. Returns -1
if item
is not found. See also indexOf()
.
Example:
RunResults:
Returns a new Int32Array
with where each item is the result of calling callback
on each item in this
. The Int32Array
passed to callback
is the this
of the call to map
.
Example:
RunResults:
Calls callback
for each item in this
in ascending order (0
to length-1
). It passes the return value of callback
for the i-1
th item as the previous
parameter for the i
th item. Returns the result from the last call to callback
. If initialValue
is not specified, callback
will first be called on this[1]
with previous
set to this[0]
. The Int32Array
passed to callback
is the this
of the call to reduce
.
Example:
RunResults:
Calls callback
for each item in this
in descending order (length-1
to 0
). It passes the return value of callback
for the i+1
th item as the previous
parameter for the i
th item. Returns the result from the last call to callback
. If initialValue
is not specified, callback
will first be called on this[this.length - 2]
with previous
set to this[this.length - 1]
. The Int32Array
passed to callback
is the this
of the call to reduceRight
.
Example:
RunResults:
Copies items from array
into this
starting at this[offset]
. Copied items are converted to 32 bit integers before storing in this
.
Example:
RunResults:
Copies items from array
into this
starting at this[offset]
. array
can be any of the typed array types and the copied items will be converted to 32 bit integers before storing in this
.
Example:
RunResults:
Returns a new Int32Array
which is composed of the items this[start], this[start + 1], ..., this[end - 1]
. Note that item[end]
is not included. If start
or end
is negative, the value is added to this.length
before performing the slice. If end
is not specified, this.length
is used.
Example:
RunResults:
Returns true
if callback
returns true
for at least one item in this
. Otherwise returns false
. The Int32Array
passed to callback
is the this
of the call to some
.
Example:
RunResults:
Sort the items of this
using comparisonFunction
to determine the sort order and returns this
. The Number returned by comparisonFunction
should be 0
if x
and y
are equal, negative if x
is less than y
, or positive if x
is greater than y
. If comparisonFunction
is not specified, the items will be sorted in numeric order. Returns this
.
Example:
RunResults:
Returns a new Int32Array that is a view on top of this
containing items this[begin]
, this[begin + 1]
, ..., this[end - 1]
. The 0th item in the returned array in the same memory location as this[begin]
. If end
is not specified, this.length
is used.
