org.red5.server.messaging.OOBControlMessage
Out-of-band control message used by inter-components communication which are connected with pipes. Out-of-band data is a separate data stream used for specific purposes (in TCP it's referenced as "urgent data"), like lifecycle control. 'Target' is used to represent the receiver who may be interested for receiving. It's a string of any form. XXX shall we design a standard form for Target, like "class.instance"? @author The Red5 Project @author Steven Gong (steven.gong@gmail.com)
