public boolean contains(Object o)
Returns whether a given (File) object is included in the list.
Parameters:
o - - The file object to test.
Returns:
true if the list contains the given object.

fireContentsChanged

public void fireContentsChanged()
Fires a content change event.

getDirectories

public Vector getDirectories()
Returns a Vector of (java.io.File) objects containing the directories in this list.
Returns:
a Vector

getElementAt

public Object getElementAt(int index)
Returns the (java.io.File) object at an index in the list.
Specified by:
getElementAt in interface ListModel
Parameters:
index - The list index
Returns:
a File object

getFiles

public Vector getFiles()
Returns a Vector of (java.io.File) objects containing the files in this list.
Returns:
a Vector

getSize

public int getSize()
Returns the size of the list, which only includes directories if the JFileChooser is set to DIRECTORIES_ONLY. Otherwise, both directories and files are included in the count.
Specified by:
getSize in interface ListModel
Returns:
The size of the list.

indexOf

public int indexOf(Object o)
Returns the index of an (java.io.File) object in the list.
Parameters:
