Class CheckSource

    java.lang.Object
      weka.filters.CheckSource

All Implemented Interfaces:
  OptionHandler, RevisionHandler

    public class CheckSource

extends java.lang.Object
implements OptionHandler, RevisionHandler

A simple class for checking the source generated from Filters implementing the `weka.filters.Sourcable` interface. It takes a filter, the classname of the generated source and the dataset the source was generated with as parameters and tests the output of the built filter against the output of the generated source. Use option '-h' to display all available commandline options. Valid options are:

     -W <classname and options>
      The filter (incl. options) that was used to generate
      the source code.

     -S <classname>
      The classname of the generated source code.

     -t <file>
      The training set with which the source code was generated.

     -c <index>
      The class index of the training set. 'first' and 'last' are
      valid indices.
      (default: none)

Options after -- are passed to the designated filter.
