Method Detail

getParentOfPath

public String getParentOfPath(String path)

Description copied from class: VFS

Returns the parent of the specified path. This must be overridden to return a non-null value for browsing of this filesystem to work.

Overrides:

getParentOfPath in class VFS

Parameters:

path - The path

constructPath

public String constructPath(String parent,
                            String path)

Description copied from class: VFS

Constructs a path from the specified directory and file name component. This must be overridden to return a non-null value, otherwise browsing this filesystem will not work.

Unless you are writing a VFS, this method should not be called directly. To ensure correct behavior, you must call MiscUtilities.constructPath(String,String) instead.

Overrides:

constructPath in class VFS

Parameters:

parent - The parent directory

path - The path

getFileSeparator

public char getFileSeparator()

Description copied from class: VFS

Returns the file separator used by this VFS.

Overrides:

getFileSeparator in class VFS

                    String path)

Description copied from class: VFS

Saves the specifies buffer. The default implementation posts an I/O request to the I/O thread.

Overrides:

save in class VFS

Parameters:

view - The view

buffer - The buffer

insert

public boolean insert(View view,
                      Buffer buffer,
                      String path)

Description copied from class: VFS

Inserts a file into the specified buffer. The default implementation posts an I/O request to the I/O thread.

Overrides:

insert in class VFS

Parameters:

view - The view

buffer - The buffer

path - The path

_canonPath

public String _canonPath(Object session,
                         String path,
                         Component comp)
                  throws IOException

Returns the canonical form if the specified path name. For example, ~ might be expanded to the user's home directory.

Overrides:

_canonPath in class VFS

Parameters:

session - The session

path - The path

comp - The component that will parent error dialog boxes

Throws:

IOException - if an I/O error occurred
