public class SetInstancesPanel extends javax.swing.JPanel
A panel that displays an instance summary for a set of instances and lets the user open a set of instances from either a file or URL. Instances may be obtained either in a batch or incremental fashion. If incremental reading is used, then the client should obtain the Loader object (by calling getLoader()) and read the instances one at a time. If batch loading is used, then SetInstancesPanel will load the data into memory inside of a separate thread and notify the client when the operation is complete. The client can then retrieve the instances by calling getInstances().- Version:

Constructor Detail
-
SetInstancesPanel
public SetInstancesPanel()
Default constructor
-
SetInstancesPanel
public SetInstancesPanel(boolean showZeroInstancesAsUnknown, ConverterFileChooser chooser)
Create the panel.- Parameters:
showZeroInstancesAsUnknown
- whether to display zero instances as unknown (e.g., when reading data incrementally)chooser
- the file chooser to use (may be null to use the default file chooser)
-
-
Method Detail
-
setParentFrame
public void setParentFrame(javax.swing.JFrame parent)
Sets the frame, this panel resides in. Used for displaying the close button, i.e., the close-button is visible if the given frame is not null.- Parameters:
parent
- the parent frame
-
getParentFrame
public javax.swing.JFrame getParentFrame()
Returns the current frame the panel knows of, that it resides in. Can be null.- Returns:
- the current parent frame
-
closeFrame
public void closeFrame()
closes the frame, i.e., the visibility is set to false
-
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.
-
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.
-
setInstances
public void setInstances(Instances i)
Updates the set of instances that is currently held by the panel- Parameters:
i
- a value of type 'Instances'
-
getInstances
public Instances getInstances()
Gets the set of instances currently held by the panel- Returns:
- a value of type 'Instances'
-
getLoader
public Loader getLoader()
Gets the currently used Loader- Returns:
- a value of type 'Loader'
-
getSummary
public InstancesSummaryPanel getSummary()
Gets the instances summary panel associated with this panel- Returns:
- the instances summary panel
-
setReadIncrementally
public void setReadIncrementally(boolean incremental)
Sets whether or not instances should be read incrementally by the Loader. If incremental reading is used, then the client should obtain the Loader object (by calling getLoader()) and read the instances one at a time. If batch loading is used, then SetInstancesPanel will load the data into memory inside of a separate thread and notify the client when the operation is complete. The client can then retrieve the instances by calling getInstances().- Parameters:
incremental
- true if instances are to be read incrementally
-
getReadIncrementally
public boolean getReadIncrementally()
Gets whether instances are to be read incrementally or not- Returns:
- true if instances are to be read incrementally
-

public void addPropertyChangeListener(java.beans.PropertyChangeListener l)
Adds a PropertyChangeListener who will be notified of value changes.- Overrides:
addPropertyChangeListener

l
- a value of type 'PropertyChangeListener'
-
