public ForwardingManager()

Method Detail

configure

public void configure()

Open the log service tracker. The tracker is customized to attach a LogWriter to all registered log reader services (and detach it on un-registration, of course). Already existing log entries are forwarded to the LogWriter as well. No provisions have been taken to avoid the duplicate output that can occur if a message is logged between registering the LogWriter and forwarding stored log entries.
