Checks whether user has a daemon.

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.

HaveDaemon Syntax

%bool = %daem: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
