toJS property

JSArrayBuffer get toJS

Converts this ByteBuffer to a JSArrayBuffer by either casting, unwrapping, or cloning the ByteBuffer.

Throws if the ByteBuffer wraps a JS SharedArrayBuffer.

Note

Depending on whether code is compiled to JavaScript or Wasm, this conversion will have different semantics. When compiling to JavaScript, ByteBuffers are either ArrayBuffers or SharedArrayBuffers so this will just check the type and cast. When compiling to Wasm, this ByteBuffer may or may not be a wrapper depending on if it was converted from JavaScript or instantiated in Dart. If it's a wrapper, this method unwraps it and either returns the ArrayBuffer or throws if the unwrapped buffer was a SharedArrayBuffer. If it's instantiated in Dart, this method clones this ByteBuffer's values into a new JSArrayBuffer. Avoid assuming that modifications to this ByteBuffer will affect the JSArrayBuffer and vice versa unless it was instantiated in JavaScript.

Implementation

external JSArrayBuffer get toJS;
