  Constant Field Values

Constructor Detail

### FileVFS

    public FileVFS()

Method Detail

### getParentOfPath

    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

### getTwoStageSaveName

    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
