The meta library provides information about the running ruleset. The following functions are available:
meta:rid() -returns the ruleset ID of the current running ruleset.meta:version()returns the version of the currently running ruleset.-meta:callingRID()returns the RID of the calling ruleset if running in a module, or the current ruleset ID otherwise.-meta:callingVersion()returns the version of the calling ruleset if running in a module, or the current ruleset version otherwise.-meta:moduleRID()returns the RID of the module if running in a module, or the current ruleset ID otherwise.-meta:moduleVersion()returns the version of the module if running in a module, or the current ruleset version otherwise.-meta:inModule()returns a Boolean value indicating whether the current code is running in a module.-meta:host()- returns the hostname of the rules engine evaluating the ruleset. Note: this is the public name, not the individual machine name.meta:rulesetName()- returns the name from the meta sections of the current rulesetmeta:rulesetAuthor()- returns the author from the meta sections of the current rulesetmeta:rulesetDescription()- returns the description from the meta sections of the current rulesetmeta:eci()- returns the event channel identifier on which the current event was raise
Note, in the case of meta:moduleRID(), meta:moduleVersion(), and meta:inModule(), care has been taken to preserve static behavior. So, for example, if you do the following, you should get the result you expect based on static function semantics:
