Method Detail

addAcceptedConnection

public boolean addAcceptedConnection(TNonblockingTransport accepted)

Hands off an accepted connection to be handled by this thread. This method will block if the queue for new connections is at capacity.

Parameters:

accepted - The connection that has been accepted.

Returns:

true if the connection has been successfully added.

run

public void run()

The work loop. Handles selecting (read/write IO), dispatching, and managing the selection preferences of all existing connections.
