BasicDirectoryModel (Java Platform SE 6)

This documentation differs from the official API. Jadeite adds extra features to the API including: variable font sizes, constructions examples, placeholders for classes and methods, and auto-generated “See Also” links. Additionally it is missing some items found in standard Javadoc documentation, including: generics type information, “Deprecated” tags and comments, “See Also” links, along with other minor differences. Please send any questions or feedback to bam@cs.cmu.edu.

Constructor Detail

BasicDirectoryModel

public BasicDirectoryModel(JFileChooser filechooser)

Parameters:: filechooser

Method Detail

addPropertyChangeListener

public void addPropertyChangeListener(PropertyChangeListener listener)

Adds a PropertyChangeListener to the listener list. The listener is registered for all bound properties of this class.

If listener is null, no exception is thrown and no action is performed.

Parameters:: listener - the property change listener to be added

contains

public boolean contains(Object o)

Parameters:: o

fireContentsChanged

public void fireContentsChanged()

firePropertyChange

protected void firePropertyChange(String propertyName,
                                  Object oldValue,
                                  Object newValue)

Support for reporting bound property changes for boolean properties. This method can be called when a bound property has changed and it will send the appropriate PropertyChangeEvent to any registered PropertyChangeListeners.

Parameters:: propertyName - the property whose value has changed; oldValue - the property's previous value; newValue - the property's new value

getDirectories

public Vector getDirectories()

getElementAt

public Object getElementAt(int index)

Parameters:: index

getFiles

public Vector getFiles()

getPropertyChangeListeners

public PropertyChangeListener[] getPropertyChangeListeners()

Returns an array of all the property change listeners registered on this component.

Returns:: all of this component's PropertyChangeListeners or an empty array if no property change listeners are currently registered

getSize

public int getSize()

indexOf

public int indexOf(Object o)

Parameters:: o

intervalAdded

public void intervalAdded(ListDataEvent e)

Obsolete - not used.

Parameters:: e

intervalRemoved

public void intervalRemoved(ListDataEvent e)

Obsolete - not used.

Parameters:: e

invalidateFileCache

public void invalidateFileCache()

This method is used to interrupt file loading thread.

lt

protected boolean lt(File a,
                     File b)

Parameters:: a; b

propertyChange

public void propertyChange(PropertyChangeEvent e)

Parameters:: e

removePropertyChangeListener

public void removePropertyChangeListener(PropertyChangeListener listener)

Removes a PropertyChangeListener from the listener list.

If listener is null, no exception is thrown and no action is performed.

Parameters:: listener - the PropertyChangeListener to be removed

renameFile

public boolean renameFile(File oldFile,
                          File newFile)

Renames a file in the underlying file system.

Parameters:: oldFile - a File object representing the existing file; newFile - a File object representing the desired new file name
Returns:: true if rename succeeded, otherwise false

sort

protected void sort(Vector v)

Parameters:: v

validateFileCache

public void validateFileCache()
