Method Detail

getParentOfPath

@Nonnull
public java.lang.String getParentOfPath(java.lang.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 java.lang.String constructPath(java.lang.String parent,
                                      java.lang.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

getTwoStageSaveName

@Nullable
public java.lang.String getTwoStageSaveName(java.lang.String path)

Returns a temporary file name based on the given path.

If the directory where the file would be created cannot be written (i.e., no new files can be created in that directory), this method returns null.

Overrides:

getTwoStageSaveName in class VFS

Parameters:

path - The path name

save

public boolean save(View view,
                    Buffer buffer,
                    java.lang.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

path - The path

insert

public boolean insert(View view,
                      Buffer buffer,
                      java.lang.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

recursiveDelete

public static boolean recursiveDelete(java.io.File path)

#

Parameters:

path - the directory path to recursive delete

Returns:

true if successful, else false

                            throws java.io.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:
