Class XMLExperiment

  • All Implemented Interfaces:
    RevisionHandler
    public class XMLExperiment
extends XMLBasicSerialization
    This class serializes and deserializes an Experiment instance to and fro XML.
    It omits the options from the Experiment, since these are handled by the get/set-methods. For the Classifier class with all its derivative classes it stores only debug and options. For SplitEvaluator and ResultProducer only the options are retrieved. The PropertyNode is done manually since it has no get/set-methods for its public fields.
    Since there's no read-method for m_ClassFirst we always save it as false.

                 throws java.lang.Exception
        for testing only. if the first argument is a filename with ".xml" as extension it tries to generate an instance from the XML description and does a toString() of the generated object. Otherwise it loads the binary file, saves the XML representation in a file with the original filename appended by ".xml" and once again in a binary file with the original filename appended by ".exp".
        Parameters:
        args - the commandline arguments
        Throws:
        java.lang.Exception - if something goes wrong, e.g., file not found
