Hello, This is quite general question.
I have a method, which is passed as an argument a nsIInputStream pointer (e.g. SetUploadStream() in Netlib's nsHttpChannel.cpp). Is there any way for me to find out what other interfaces this object implements (e.g. nsIFileInputStream, nsIBufferedInputStream, etc.) without having to call do_QueryInterface for each interface that I think this object might implement? For example, if the object implements an interface that I don't know about, is there a way for me to find out which one? I am looking for something of the sort of being able to "ask" the object "What is the list of all interfaces you implement?" rather than asking it "Do you implement this interface?" multiple times, for each interface separately.
