eventChannelScript
Runs a eventChannel subsetter script via JSR223. The event is put as "event" and the channel as "channel". The channel and event objects are a VelocityChannel and VelocityEvent, respectively, the same classes used in the templates for the printlineChannelProcess. See the scripting tutorial for more information on inlining scripts into a SOD recipe.
Example
<eventChannelScript type="jython">
if channel.getOrientationCode() == 'N' and abs(channel.getAzimuth()) > 5:
# reject N channels that are more than 5 degrees from north
result = util.fail('channel not really North'+channel.getAzimuth())
</eventChannelScript>
