protected SocketChannel acceptImpl() throws IOException

Implements abstract org.freedesktop.dbus.connections.transports.AbstractTransport.acceptImpl.

Doc from org.freedesktop.dbus.connections.transports.AbstractTransport.acceptImpl.

Method to accept new incoming listening connections.
This is the place where accept() is called on the server socket created by bindImpl().
Therefore this method will block until a client is connected.

Returns:SocketChannel

newly connected client socket

Must be false if bindImpl() was not called.

Returns:boolean
