Class XMLExperiment

java.lang.Object

weka.core.xml.XMLSerialization

weka.core.xml.XMLBasicSerialization

weka.experiment.xml.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.

Constructor Details

XMLExperiment

public XMLExperiment()
              throws Exception

initializes the serialization

Throws:

Exception - if initialization fails

Method Details

clear

public void clear()
           throws Exception

generates internally a new XML document and clears also the IgnoreList and the mappings for the Read/Write-Methods

Overrides:

clear in class XMLBasicSerialization

Throws:

Exception - if initializing fails

writePropertyNode

public Element writePropertyNode(Element parent,
 Object o,
 String name)
                          throws Exception

adds the given PropertyNode to a DOM structure.

Parameters:

parent - the parent of this object, e.g. the class this object is a member of

o - the Object to describe in XML

name - the name of the object

Returns:

the node that was created

Throws:

Exception - if the DOM creation fails

readPropertyNode

public Object readPropertyNode(Element node)
                        throws Exception

builds the PropertyNode from the given DOM node.

Parameters:

node - the associated XML node

Returns:

the instance created from the XML description

Throws:

Exception - if instantiation fails

See Also:

• DefaultListModel

getRevision

public String getRevision()

Returns the revision string.

Specified by:

getRevision in interface RevisionHandler

Overrides:

getRevision in class XMLBasicSerialization

Returns:

the revision

main

public static void main(String[] args)
                 throws 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:

Exception - if something goes wrong, e.g., file not found
