* nsIThreadRetargetableStreamListener
* To be used by classes which implement nsIStreamListener and whose
* OnDataAvailable callback may be retargeted for delivery off the main thread.
interface nsIThreadRetargetableStreamListener : nsISupports
* Checks this listener and any next listeners it may have to verify that
* they can receive OnDataAvailable off the main thread. It is the
* responsibility of the implementing class to decide on the criteria to
* determine if retargeted delivery of these methods is possible, but it must
* check any and all nsIStreamListener objects that might be called in the
* listener chain.
* An exception should be thrown if a listener in the chain does not
* support retargeted delivery, i.e. if the next listener does not implement
* nsIThreadRetargetableStreamListener, or a call to its checkListenerChain()
* fails.
