implements Explorer.CapabilitiesFilterChangeListener, Explorer.ExplorerPanel, Explorer.LogHandler
This panel controls simple preprocessing of instances. Summary
information on instances and attributes is shown. Filters may be
configured to alter the set of instances. Altered instances may
also be saved.

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. -
saveInstancesToFile
saves the data with the specified saver- Parameters:
saver
- the saver to use for storing the datainst
- the data to save
-
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
Loads instances from an SQL query the user provided with the SqlViewerDialog, 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.- Parameters:

generateInstances
public void generateInstances()sets Instances generated via DataGenerators (pops up a Dialog) -
setInstancesFromFile
Loads results from a set of instances retrieved with the supplied loader. This is started in the IO thread, and a dialog is popped up if there's a problem.- Parameters:
loader
- the loader to use
-
setInstancesFromDB
Loads instances from a database- Parameters:
iq
