Interface StreamSource

All Known Implementing Classes:

ClientSocketStreamSource, ServerSocketStreamSource, SocketStreamSource

public interface StreamSource

A source of input and output streams for use with stream-based TransportLayers. Implementations should contain the necessary information for reconnecting streams as necessary. For example a ServerSocket-based implementation should be able to listen for fresh connections and get new streams from them (this must be done when refresh() is called).
