                                boolean canRead,
                                boolean canWrite)
                         throws java.io.IOException

Description copied from interface: P2PSocketReceiver

Called when a socket is available for read/write

Specified by:

receiveSelectResult in interface P2PSocketReceiver<Identifier>

Throws:

java.io.IOException

read

protected boolean read()
                throws java.io.IOException

Throws:

java.io.IOException

                     P2PSocketReceiver<Identifier> receiver)

Description copied from interface: P2PSocket

Must be called every time a Read/Write occurs to continue operation. Can cancel this task by calling with null.

Specified by:

register in interface P2PSocket<Identifier>

Parameters:

wantToRead - if you want to read from this socket

wantToWrite - if you want to write to this socket

receiver - will have receiveSelectResult() called on it note that you must call select() each time receiveSelectResult() is called. This is so your application can properly handle flow control
