|
* This interface provides a means to configure and use a input stream pump

* instance. The input stream pump will asynchronously read from a input
|
|
* stream, and push data to a nsIStreamListener instance. It utilizes the
|
|
* current thread's nsIEventTarget in order to make reading from the stream
|
|
* asynchronous.
|
|
*
|
|
* If the given stream supports nsIAsyncInputStream, then the stream pump will
|
|
* call the stream's AsyncWait method to drive the stream listener. Otherwise,
|
|
* the stream will be read on a background thread utilizing the stream
|
|
* transport service. More details are provided below.
