HaveDaemon (Daemon property)
Is the thread associated with this Daemon accessible? (Daemon class)
HaveDaemon is a member of the Daemon class
This method returns a Boolean enumeration that indicates whether the daemon thread associated with the Daemon method object is accessible.
Syntax
%boolean = daemon:HaveDaemon
Syntax terms
| %bool | A declared enumeration object of type Boolean to contain the returned value of HaveDaemon. |
|---|---|
| %daem | A previously defined and instantiated Daemon object. |
HaveDaemon returns True unless the daemon thread logged off, for whatever reason.
Example
In the following example, a global daemon updates an XML document, then HaveDaemon verifies the continued existence of the daemon.
b %speed is object daemon global %list is object stringList %tiny is object xmlDoc %bool is enumeration boolean %speed = new %speed:run('*LOWER') %list = new text to %list b %doc is object xmlDoc %(daemon):getInputObject(%doc) %doc:selectSingleNode('/out/in'):addAttribute('foo','bar') %(daemon):returnObject(%doc) end end text %tiny = new %tiny:loadXml('<out><in></in></out>') %speed:run(%list, %tiny, %tiny) %tiny:print %bool = %speed:havedaemon Print '%bool is ' %bool:tostring end
The example above returns this result:
<out><in foo="bar"/></out>%bool is True
