isAccessorArray

Test if a value is an array-like object supporting the accessor (get/set) protocol.

An accessor array is defined as either an Array, Typed Array, or an array-like Object (excluding strings and functions) having get and set methods for accessing array elements.

Installation

npm install @stdlib/assert-is-accessor-array

Usage

var isAccessorArray = require( '@stdlib/assert-is-accessor-array' );

isAccessorArray( value )

Tests if a value is an array-like object supporting the accessor (get/set) protocol.

var Complex128Array = require( '@stdlib/array-complex128' );
var Complex128 = require( '@stdlib/complex-float64' );

// Create a new complex number array:
var arr = new Complex128Array( 10 );

// Retrieve a complex number element:
var z = arr.get( 0 );
// returns <Complex128>

// Set a complex number element:
arr.set( new Complex128( 1.0, 1.0 ), 0 );

// ...

// Check whether an array is an accessor array:
var bool = isAccessorArray( arr );
// returns true

Examples

var Int8Array = require( '@stdlib/array-int8' );
var Uint8Array = require( '@stdlib/array-uint8' );
var Uint8ClampedArray = require( '@stdlib/array-uint8c' );
var Int16Array = require( '@stdlib/array-int16' );
var Uint16Array = require( '@stdlib/array-uint16' );
var Int32Array = require( '@stdlib/array-int32' );

var Complex128Array = require( '@stdlib/array-complex128' );
var Complex64Array = require( '@stdlib/array-complex64' );
var isAccessorArray = require( '@stdlib/assert-is-accessor-array' );

var bool = isAccessorArray( new Complex128Array( 10 ) );
// returns true

// returns true

// returns false

// returns false

// returns false

bool = isAccessorArray( isAccessorArray );
// returns false

// returns false

bool = isAccessorArray( 3.14 );
// returns false
