propertyChange

public void propertyChange(PropertyChangeEvent e)
Description copied from interface: PropertyChangeListener
This method gets called when a bound property is changed.

Specified by:
propertyChange in interface PropertyChangeListener
Parameters:
e - A PropertyChangeEvent object describing the event source and the property that has changed.

invalidateFileCache

public void invalidateFileCache()
This method is used to interrupt file loading thread.


getDirectories

public Vector<File> getDirectories()

getFiles

public Vector<File> getFiles()

validateFileCache

public void validateFileCache()

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
Since:
1.4

fireContentsChanged

public void fireContentsChanged()

getSize

public int getSize()
Description copied from interface: ListModel
Returns the length of the list.

Specified by:
getSize in interface ListModel
Returns:
the length of the list

contains

public boolean contains(Object o)

indexOf

public int indexOf(Object o)

getElementAt

public Object getElementAt(int index)
Description copied from interface: ListModel
Returns the value at the specified index.

Specified by:
getElementAt in interface ListModel
Parameters:
index - the requested index
Returns:
the value at index

intervalAdded

public void intervalAdded(ListDataEvent e)
Obsolete - not used.


intervalRemoved

public void intervalRemoved(ListDataEvent e)
Obsolete - not used.


sort

protected void sort(Vector<? extends File> v)

lt

protected boolean lt(File a,
                     File b)

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
Since:
1.6
See Also:
removePropertyChangeListener(java.beans.PropertyChangeListener), getPropertyChangeListeners()

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
Since:
1.6
See Also:
addPropertyChangeListener(java.beans.PropertyChangeListener), getPropertyChangeListeners()

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
Since:
1.6
See Also:
addPropertyChangeListener(java.beans.PropertyChangeListener), removePropertyChangeListener(java.beans.PropertyChangeListener), PropertyChangeSupport.getPropertyChangeListeners()

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
