By default, the controller tries to invoke a method called "run" with no arguments on the specified object.

The following simple command invokes the run method on the BaselineUpdate script object:

java Controller --app-config AppConfig.xml BaselineUpdate

If a method name is specified, the controller looks for a method with that name on the specified object and invokes it. For example, the following command executes the applyIndex method on the DgraphCluster object:

java Controller --app-config AppConfig.xml DgraphCluster applyIndex

In addition to no-argument method invocation, the controller allows any number of String arguments to be passed to a method. The following example shows the releaseLock method being invoked on the LockManager object with the single String argument "update_lock" specifying the name of the lock to release:

java Controller --app-config AppConfig.xml LockManager releaseLock 
  update_lock
