public class SHARED_LOOPBACK extends TP
Loopback transport shared by all channels within the same VM. Property for testing is that no messages are lost. Allows us to test various protocols (with ProtocolTester) at maximum speed.- Version:

toString
public java.lang.String toString()
Description copied from class:TP
debug only

sendToAllMembers
public void sendToAllMembers(byte[] data, int offset, int length) throws java.lang.Exception
Description copied from class:TP
Send to all members in the group. UDP would use an IP multicast message, whereas TCP would send N messages, one for each member- Specified by:
sendToAllMembers
in classTP
- Parameters:
data
- The data to be sent. This is not a copy, so don't modify it- Throws:
java.lang.Exception
-
sendToSingleMember
public void sendToSingleMember(Address dest, byte[] data, int offset, int length) throws java.lang.Exception
Description copied from class:TP
Send to all members in the group. UDP would use an IP multicast message, whereas TCP would send N messages, one for each member- Specified by:
sendToSingleMember
in classTP
- Parameters:
dest
- Must be a non-null unicast addressdata
- The data to be sent. This is not a copy, so don't modify it- Throws:
java.lang.Exception
-
postUnmarshalling
public void postUnmarshalling(Message msg, Address dest, Address src, boolean multicast)
- Specified by:
postUnmarshalling
in classTP
-
postUnmarshallingList
public void postUnmarshallingList(Message msg, Address dest, boolean multicast)
- Specified by:
postUnmarshallingList
in classTP
-
init
public void init() throws java.lang.Exception
Description copied from class:Protocol
Called after instance has been created (null constructor) and before protocol is started. Properties are already set. Other protocols are not yet connected and events cannot yet be sent.
-
start
public void start() throws java.lang.Exception
Description copied from class:TP
Creates the unicast and multicast sockets and starts the unicast and multicast receiver threads- Overrides:
start
in classTP
- Throws:
java.lang.Exception
- Thrown if protocol cannot be started successfully. This will cause the ProtocolStack to fail, soChannel.connect(String)
will throw an exception
-
stop
public void stop()
Description copied from class:Protocol
This method is called on aChannel.disconnect()
. Stops work (e.g. by closing multicast socket). Will be called from top to bottom. This means that at the time of the method invocation the neighbor protocol below is still working. This method will replace the STOP, STOP_OK, CLEANUP and CLEANUP_OK events. The ProtocolStack guarantees that when this method is called all messages in the down queue will have been flushed
-
down
public java.lang.Object down(Event evt)
Description copied from class:TP
Caller by the layer above this layer. Usually we just put this Message into the send queue and let one or more worker threads handle it. A worker thread then removes the Message from the send queue, performs a conversion and adds the modified Message to the send queue of the layer below it, by calling down()).
