Is the current thread controlled by a Daemon? (Daemon class)
AmDaemon returns a Boolean enumeration to indicate whether AmDaemon was issued on a daemon thread associated with a Daemon object.
Syntax
%boolean = %(Daemon):AmDaemon
Syntax terms
| %boolean | An enumeration object of type Boolean to contain the returned value of AmDaemon. AmDaemon returns True if issued on a Daemon-associated thread; otherwise it returns False. |
|---|---|
| %(Daemon) | The class name in parentheses denotes a shared method. AmDaemon can also be invoked via a Daemon object variable, which may be Null. |
Usage notes
- Since a daemon thread can run web requests, socket server requests, and $CommndL requests, AmDaemon distinguishes a daemon thread that is working for a Daemon object from, say, a daemon thread running a web request. This distinction is particularly important for certain methods, such as ReturnToMaster or ReturnObject, that can only be issued on a thread associated with a Daemon object.
- If a daemon thread was spawned by RunIndependently, AmDaemon returns
Falsesince the daemon thread has no returnable objects.
