Examples of BridgeMsg

lt.baltic_amadeus.jqbridge.msg.BridgeMsg
Represents a message that is sent across two ports. Every message that comes in is converted to an instance of BridgeMsg or its descendant class. When a message is going to be sent it is converted to the most appropriate native message type. @see lt.baltic_amadeus.jqbridge.providers.Port @author Baltic Amadeus, JSC @author Antanas Kompanas
