Package gda.jython.logger

Class ActiveMqTerminalLogger

java.lang.Object

gda.jython.logger.ActiveMqTerminalLogger

All Implemented Interfaces:

LineLogger, gda.observable.IObserver

public class ActiveMqTerminalLogger
extends Object
implements LineLogger, gda.observable.IObserver

Class to send text shown in Jython terminal window to ActiveMQ. Destination topic is DEFAULT_QUEUE_TOPIC. This is added as a listener to JythonServer - the update method sends a text representation of all TerminalInput, TerminalOutput and ScanDataPoint messages to ActiveMq in same format as displayed in Jython console. This can also be used in place of a terminal logger RedirectableFileLogger to send data to ActiveMq rather than a file, by creating the bean with the no-arg constructor and passing it to the logger adapter objects.
