        Description copied from class: AbstractOptionHandler
        This method describes the implementation of how to prepare this object for use. All classes that extends this class have to implement prepareForUseImpl and not prepareForUse since prepareForUse calls prepareForUseImpl.

        Parameters:
        monitor - the TaskMonitor to use
        repository - the ObjectRepository to use
      • estimatedRemainingInstances

        public long estimatedRemainingInstances()
        Description copied from interface: ExampleStream

        Specified by:
        estimatedRemainingInstances in interface ExampleStream
        Returns:
        the estimated number of instances to get from this stream
