Examples
- In the following example, a global daemon updates an XML document, then HaveDaemon verifies the continued existence of the daemon.
begin %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 begin %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
