reinterpret
Reinterpret a
BooleanArray
as aUint8Array
.
Installation
npm install @stdlib/strided-base-reinterpret-boolean
Usage
var reinterpret = require( '@stdlib/strided-base-reinterpret-boolean' );
reinterpret( x, offset )
Returns a Uint8Array
view of a BooleanArray
.
var BooleanArray = require( '@stdlib/array-bool' );
var x = new BooleanArray( 10 );
var view = reinterpret( x, 0 );
// returns <Uint8Array>
var bool = ( view.buffer === x.buffer );
// returns true
var len = view.length;
// returns 10
The offset
argument specifies the starting index of the returned Uint8Array
view relative to the BooleanArray
.
var BooleanArray = require( '@stdlib/array-bool' );
var x = new BooleanArray( [ true, false, false, true, true, false ] );
var view = reinterpret( x, 2 );
// returns <Uint8Array>
var len = view.length;
// returns 4
var v = view[ 0 ];
// returns 0
v = view[ 1 ];
// returns 1
Examples
var BooleanArray = require( '@stdlib/array-bool' );
var reinterpret = require( '@stdlib/strided-base-reinterpret-boolean' );
// Define a boolean array:
var x = new BooleanArray( [ true, false, false, true, true, false ] );
// returns <BooleanArray>
// Reinterpret as a `uint8` array:
var view = reinterpret( x, 0 );
// returns <Uint8Array>
// Set view elements:
view[ 0 ] = 0;
view[ 1 ] = 1;
// Get the first element of the boolean array:
var v = x.get( 0 );
// returns false
// Get the second element of the boolean array:
v = x.get( 1 );
// returns true
