      • prepareForUseImpl

        public void prepareForUseImpl​(TaskMonitor monitor,
                                      ObjectRepository repository)
        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.
        Specified by:
        prepareForUseImpl in class AbstractOptionHandler
        Parameters:
        monitor - the TaskMonitor to use
        repository - the ObjectRepository to use
      • getHeader

        public InstancesHeader getHeader()
        Description copied from interface: ExampleStream
        Gets the header of this stream. This is useful to know attributes and classes. InstancesHeader is an extension of weka.Instances.
        Returns:
        the header of this stream
      • estimatedRemainingInstances

        public long estimatedRemainingInstances()
        Description copied from interface: ExampleStream
        Gets the estimated number of remaining instances in this stream
        Returns:
        the estimated number of instances to get from this stream
      • hasMoreInstances

        public boolean hasMoreInstances()
        Description copied from interface: ExampleStream
        Gets whether this stream has more instances to output. This is useful when reading streams from files.

        true if this stream has more instances to output
      • nextInstance

        public InstanceExample nextInstance()
        Description copied from interface: ExampleStream
        Gets the next example from this stream.

      • restart

        public void restart()
        Description copied from interface: ExampleStream
