Obtaining subscription information
You can use the position service interface object to obtain information about subscriptions and position trackers. The following code extract provides examples of doing this.
action queryDemonstration() {
// Use the interface object to obtain information for all subscriptions:
com.apama.position.SubscriptionDetails > subscriptions;
subscriptions := psIface.getAllSubscriptionDetails();
// Get the details for a specific subscription. You must specify
// the Id for the subscription. The Id is returned from a successful
// subscription request.
integer subscriptionId := 1;
com.apama.position.SubscriptionDetails details :=
psIface.getSubscriptionDetails( subscriptionId );
// Get the current position of a subscription:
com.apama.position.Position position :=
psInterface.getCurrentPosition( subscriptionId );
// Get details about a specific position tracker, and provide a
// boolean that indicates whether the asynchronous call should
// wait to respond if the position tracker has not yet been registered.
psIface.getTrackerInfo( "MyPositionTrackerName",
true, cbTrackerDetails );
// This action is called when information about the position tracker
// is returned:
action cbTrackerDetails( com.apama.position.TrackerInfo trackerInfo ) {
log "TRACKER DETAILS: Name="+trackerInfo.name+" :
Type="+trackerInfo.type+" :
Context it was created in: "+trackerInfo.ctx.toString();
log "TRACKER CONFIG SCHEMA: "+trackerInfo.configSchema.toString();
