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.%type%.check()
method returns a SIMD data type if the parameter is a valid SIMD data type and the same as %type%
. Otherwise, a TypeError
is thrown.
Syntax
SIMD.Float32x4.check(value) SIMD.Float64x2.check(value) SIMD.Int8x16.check(value) SIMD.Int16x8.check(value) SIMD.Int32x4.check(value) SIMD.Uint8x16.check(value) SIMD.Uint16x8.check(value) SIMD.Uint32x4.check(value) SIMD.Bool8x16.check(value) SIMD.Bool16x8.check(value) SIMD.Bool32x4.check(value) SIMD.Bool64x2.check(value)
Parameters
- value
- The value to check whether it is a corresponding SIMD data type.
Return value
The corresponding SIMD data type, if valid.
Exceptions
A TypeError
, if the argument is not a valid SIMD data type or does not correspond to %type%.
Examples
Checking if a SIMD data type is valid
var a = SIMD.Float32x4(1, 2, 3, 9); SIMD.Float32x4.check(a); // Float32x4[1, 2, 3, 9] SIMD.Float32x4.check([1,2,3,4]); // TypeError SIMD.Int32x4.check(a); // TypeError as a is a Float32x4 not an Int32x4 SIMD.Int32x4.check({}); // TypeError SIMD.Int32x4.check('Hi Vector-Viktor!'); // TypeError
