SIMD.%type%.allTrue()

SIMD.js has been taken out of active development in TC39 and removed from Stage 3. It is not being pursued by web browsers for implementation anymore. SIMD operations exposed to the web are under active development within WebAssembly, with operations based on the SIMD.js operations.

The static SIMD.%BooleanType%.allTrue() method returns a Boolean indicating whether or not all lanes hold a true value.

Syntax

SIMD.Bool8x16.allTrue(value) 
SIMD.Bool16x8.allTrue(value) 
SIMD.Bool32x4.allTrue(value)
SIMD.Bool64x2.allTrue(value)

Parameters

value
The value to check whether it only holds true values.

Return value

A Boolean. Returns true if all lanes hold a true value, false otherwise.

Examples

var a = SIMD.Bool32x4(true, true, true, true);
var b = SIMD.Bool32x4(true, false, true, true);

SIMD.Bool32x4.allTrue(a); // true
SIMD.Bool32x4.allTrue(b); // false
