How to use CefV8ArrayBuffer

[magreenblatt]

It's as if GC just gives , or at least whatever mechanism tries to call ReleaseBuffer..
The only other way around this would be to have a fixed ArrayBuffer which exists for the duration of the application and just update it's contents.. but that would require exposing V8 GetContents() to modify the data on the native side.

Why can't you reuse a single ArrayBuffer created by the native code? Just keep a global reference on the JS side so it's not GC'd until the page unloads.

which seems to lead directly back into V8 itself ?

Yes.

If I create an ArrayBuffer in JS.. I can pass a reference to that in as an argument to a native method, but how would I set it's data in the native code without re-creating it?

[magreenblatt]

Use a bound method that returns an ArrayBuffer created by the native code. Like this, but returning an ArrayBuffer instead of a string: https://bitbucket.org/chromiumembedded/ ... -functions

Yep, I'm already doing that in the Execute handler, the native code creates an ArrayBuffer .. keeps a reference to it and return it to JS.. now later on another native code function needs to execute to fill that buffer with new data, thats where I'm stuck, I can't find anyway to access the data of the ArrayBuffer in the native code.

Your native code needs to keep track of the native buffer that it used to create the ArrayBuffer.

Implemented, working like a charm and no memory leaking!

Thanks a million!
