Methods

    

              

          
 Asynchronously loads a channel into a memory buffer.

 To use this interface, first call init() with a nsIStreamLoaderObserver
 that will be notified when the data has been loaded. Then call asyncOpen()
 on the channel with the nsIStreamLoader as the listener. The context
 argument in the asyncOpen() call will be passed to the onStreamComplete()
 callback.

 XXX define behaviour for sizes >4 GB


 Initialize this stream loader, and start loading the data.

 @param aObserver
        An observer that will be notified when the data is complete.
