Method Detail

addLogListener

void addLogListener(LogListener l,
                    java.lang.Object component,
                    LogLevel level,
                    long last,
                    int max)

archive - The archive to receive events for.

level - The level of events required.

last - The last event number received. The LogArchive will not send messages from before this number.

max - The maximum messages to send up to the most recent.

                       java.lang.Object component)
