Continue processing asynchronously in daemon (Daemon class)

[Introduced in Sirius Mods 8.1]

This method tells a daemon that issued a Daemon class ReturnToMaster call to continue processing from the point of that ReturnToMaster call. Unlike the Continue method, ContinueAsynchronously returns immediately, thus allowing the thread that issued ContinueAsynchronously to run in parallel with the daemon thread.


daemon:ContinueAsynchronously[( [Input= object])] Throws DaemonLost, IncorrectDaemonState

Syntax terms

daemon A previously defined Daemon object.
Input This optional, name allowed, argument is an object passed to the daemon thread. This object must be deep copyable, as described in: "Copying objects".


This subroutine can throw the following exceptions:

If the daemon thread is not in a ReturnToMaster wait when ContinueAsynchronously is issued, an IncorrectDaemonState exception is thrown. This exception will only be thrown in Sirius Mods version 8.1 and later.
If daemon is lost (probably restarted), a DaemonLost exception is thrown. Since ContinueAsynchronously does not wait for the daemon thread to do anything, a DaemonLost exception indicates that the daemon thread was lost before ContinueAsynchronously was invoked.

Usage notes

  • The Continue and ContinueIndependently methods also tell a daemon to continue from a ReturnToMaster wait.
  • Issuing ContinueAsynchronously against a transactional daemon results in request cancellation.
  • If the daemon thread and its daemons hold record locks that conflict with the parent thread's family (excluding the daemon thread and its daemons), ContinueAsynchronously results in request cancellation.
  • Once started via ContinueAsynchronously, the daemon thread is considered to be running asynchronously until a WaitAsynchronous is issued against the daemon object. This is the case, even if the daemon thread has completed processing all of the input commands.
  • While the daemon thread is running asynchronously, any methods that require interaction with it cause request cancellation.
  • WaitAsynchronous is used to retrieve any output from the commands run via ContinueAsynchronously. This includes the terminal output and any output or info object.
