Re: [webkit-dev] XHR responseArrayBuffer attribute: possible implementation

2010-10-25 Thread Geoffrey Garen
You could aid discoverability -- and programming -- by providing a set of enumerated constants on the XHR constructor, much like the Node constructor provides for NodeTypes. Another option would be to throw an exception when setting responseType to an unsupported value. Geoff On Oct 25, 2010,

True, it's not as simple as checking for the existence of an attribute, but it could throw an exception. It seems like having both asBlob and asArrayBuffer also creates the possibility of bad combinations of settings which could get confusing, especially if more types are added in the future. Chri

How do you address the discoverability issue that I raised? asBlob and asArrayBuffer have the benefit of being detectable at runtime. but, a settable responseType does not support detection of supported values. -Darin On Mon, Oct 25, 2010 at 2:54 PM, Chris Rogers wrote: > passing "undefined

2010-10-25 Thread Chris Rogers
passing "undefined" as the 4th and 5th arguments seems pretty clunky to me. Since, we already have an "asBlob" attribute, then "asArrayBuffer" like Darin suggests seems like it might be better. However, then we can get into cases where both "asBlob" and "asArrayBuffer" are set, and this problem w

The solution for .responseBlob was to add an .asBlob attribute that would need to be set to true before calling .send(). We could do the same for .responseArrayBuffer. -Darin On Mon, Oct 25, 2010 at 12:17 PM, Geoffrey Garen wrote: > Hi Chris. > > I like the efficiency of this approach. And I

2010-10-25 Thread Geoffrey Garen
Hi Chris. I like the efficiency of this approach. And I agree with your premise that a developer will probably only want one type of data (raw, text, or XML) per request, and not more than one. My biggest concern with this idea is that there's nothing obvious about the API pattern of three pro

2010-10-22 Thread Chris Rogers
A few weeks ago I brought up the idea of implementing the responseArrayBuffer attribute for XHR: http://dev.w3.org/2006/webapi/XMLHttpRequest-2/#the-responsearraybuffer-attribute One of the concerns was that it might require double the memory usage since the raw bytes would have to be accumulated
