[jboss-jira] [JBoss JIRA] Commented: (JBRULES-2376) Parser fails when accessing property/method called 'end'

[Barry Kaplan (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBRULES-2376?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12525518#action_12525518 ] 

Barry Kaplan commented on JBRULES-2376:
---------------------------------------

I'm not seeing this behavior:

with this

  update(entryPoints["downtime"].getFactHandle(downtime),
         downtime.`end`)

I get

  java.lang.RuntimeException: [41,23]: [ERR 102] Line 41:23 mismatched input ')'

with this

  update(entryPoints["downtime"].getFactHandle(downtime),
         downtime.`end`())

I get

java.lang.RuntimeException: [41,23]: [ERR 102] Line 41:23 mismatched input '('

----

where:

case class DowntimeInterval(deviceId: String, interval: Interval,
                            classification: Option[DowntimeClassification] = None,
                            id: String = ObjectId.get.toString)
        extends DeviceEvent with Logging {

  def this(deviceId: String) = this(deviceId, fromNow)
  debug("downtime: started now="+interval.start)

  def end = {
    debug("downtime: ended interval="+interval)
    this.copy(interval = this.interval.start to now)
  }
  def endd = end // alias for drools

  def classify(classification: DowntimeClassification): DowntimeInterval = {
    debug("classfied as: "+classification)
    copy(classification = Some(classification))
  }

}

Using the 'endd' method does work: 

  update(entryPoints["downtime"].getFactHandle(downtime),
         downtime.endd)

> rule "foo" dialect "java"

>    foo = new Foo()
>    e = foo.end()
> end
> The compiler fails with the following error:  [xx,yy]: [ERR 102] Line xx:yy mismatched input '('  
> If the rule is changed to (ie, remove the parens on the 'end')
> rule "foo" dialect "java"
> when
> then
>    foo = new Foo()
>    e = foo.end
> end
> The compiler error is: [0,-1]: [ERR 101] Line 0:-1 no viable alternative at input '<eof>'
