Constructor Detail

PreprocessPanel

public PreprocessPanel()

Creates the instances panel with no initial instances.

Method Detail

setLog

public void setLog(Logger newLog)

Sets the Logger to receive informational messages

Parameters:

newLog - the Logger that will now get info messages

setInstances

public void setInstances(Instances inst)

Tells the panel to use a new base set of instances.

Parameters:

inst - a set of Instances

getInstances

public Instances getInstances()

Gets the working set of instances.

Returns:

the working instances

addPropertyChangeListener

public void addPropertyChangeListener(java.beans.PropertyChangeListener l)

Adds a PropertyChangeListener who will be notified of value changes.

Parameters:

l - a value of type 'PropertyChangeListener'

removePropertyChangeListener

public void removePropertyChangeListener(java.beans.PropertyChangeListener l)

Removes a PropertyChangeListener.

Parameters:

l - a value of type 'PropertyChangeListener'

saveWorkingInstancesToFileQ

public void saveWorkingInstancesToFileQ()

Queries the user for a file to save instances as, then saves the instances in a background process. This is done in the IO thread, and an error message is popped up if the IO thread is busy.

setInstancesFromFileQ

public void setInstancesFromFileQ()

Queries the user for a file to load instances from, then loads the instances in a background process. This is done in the IO thread, and an error message is popped up if the IO thread is busy.

setInstancesFromDBQ

public void setInstancesFromDBQ()

Queries the user for a URL to a database to load instances from, then loads the instances in a background process. This is done in the IO thread, and an error message is popped up if the IO thread is busy.

setInstancesFromURLQ

public void setInstancesFromURLQ()

Queries the user for a URL to load instances from, then loads the instances in a background process. This is done in the IO thread, and an error message is popped up if the IO thread is busy.

setInstancesFromFile

public void setInstancesFromFile(java.io.File f)

Loads results from a set of instances contained in the supplied file. This is started in the IO thread, and a dialog is popped up if there's a problem.

Parameters:

f - a value of type 'File'

setInstancesFromDB

public void setInstancesFromDB(InstanceQuery iq)

Loads instances from a database

Parameters:

iq - the InstanceQuery object to load from (this is assumed to have been already connected to a valid database).

setInstancesFromURL

public void setInstancesFromURL(java.net.URL u)

Loads instances from a URL.

Parameters:

u - the URL to load from.

addUndoPoint

public void addUndoPoint()
                  throws java.lang.Exception

Backs up the current state of the dataset, so the changes can be undone.

Throws:

java.lang.Exception

undo

public void undo()

Reverts to the last backed up version of the dataset.

main

public static void main(java.lang.String[] args)

Tests out the instance-preprocessing panel from the command line.

Parameters:

args - ignored
