getEndpoint

public abstract ChannelEndpoint getEndpoint (String text)

Convenience method to create a proper endpoint object from it's string representation

Parameters:

text
string representation of the endpoint as it would be returned by Endpoint.toString()

Return:

the newly constructed endpoint

Abstract.

Throws:

IOException

listen

public abstract void listen (ChannelEndpoint localEndpoint, ConnectionListener connectionListener, Integer numberOfConnections)

Abstract.

Throws:

IOException

openChannel

public abstract CommChannel openChannel (ChannelEndpoint remoteEndpoint, CommChannelStateListener connectionListener)

Asynchoronously opens a channel to the remote endpoint. After a successfull return, the channel is in the OPENED
state but possibly not CONNECTED. When the channel transitions from open to connected connectionListener is
notified

Parameters:

remoteEndpoint
endpoint to open the channel to
connectionListener
listener to notify about channel's state changes

Abstract.

Throws:

IOException

openChannel

public abstract CommChannel openChannel (ChannelEndpoint remoteEndpoint, Integer timeout)

Synchoronously opens a channel to the remote endpoint. After a successfull return, the channel is fully
functional for both sending and receiving (state=CONNECTED). Returns when the channel is open or the timeout
expires

Parameters:

remoteEndpoint
endpoint to open the channel to
timeout
to wait for channel to become connected in milliseconds

Abstract.

Throws:

IOException

openChannel

public abstract CommChannel openChannel (ChannelEndpoint remoteEndpoint, CommChannelListener dataListener)

Synchoronously opens a channel to the remote endpoint. After a successfull return, the channel is fully
functional for both sending and receiving (state=CONNECTED). It does not return until the channel is connected or
it fails

Parameters:

remoteEndpoint
endpoint to open the channel to
dataListener
listener to be notified of incomming data. CommChannelListener is a marker interface, no concrete
class implements it. Concrete classes implement derived interfaces StreamListener and MessageListener

Abstract.

Throws:

IOException

stopListening

public abstract void stopListening (ChannelEndpoint localEndpoint)

Stops listening on the endpoint

Parameters:

localEndpoint
endpoint to stop listening on

Abstract.
