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).

Method Detail

connect

void connect()
             throws TransportException

Gets new streams. This should be called only if one of the streams is dead.

Throws:

TransportException

disconnect

void disconnect()
                throws TransportException

Closes streams and underlying connections.

Throws:

TransportException

getOutboundStream

OutputStream getOutboundStream()
                               throws TransportException

Returns:

the stream to which we write outbound messages.

Throws:

TransportException

getInboundStream

InputStream getInboundStream()
                             throws TransportException

Returns:

the stream to which we expect the remote server to send messages.

Throws:

TransportException
