| addJunction | | void addJunction(String junctionPoint, FileObject targetFile) throws FileSystemException(Code) | | Adds a junction to this file system. A junction is a link that attaches
the supplied file to a point in this file system, making it look like
part of the file system.
Parameters:
junctionPoint - The point in this file system to add the junction.
Parameters:
targetFile - The file to link to.

| addListener | | void addListener(FileObject file, FileListener listener)(Code) | | Adds a listener on a file in this file system.
Parameters:
file - The file to attach the listener to.
Parameters:
listener - The listener to add. |
| getFileSystemOptions | | FileSystemOptions getFileSystemOptions()(Code) | | Returns the FileSystemOptions used to instantiate this filesystem
|
| getLastModTimeAccuracy | | double getLastModTimeAccuracy()(Code) | | Returns the accuracy of the last modification time
ms 0 perfectly accurate, >0 might be off by this value e.g. sftp 1000ms |
| getParentLayer | | FileObject getParentLayer() throws FileSystemException(Code) | | Returns the parent layer if this is a layered file system.
The parent layer, or null if this is not a layered file system. |
| getRootName | | FileName getRootName()(Code) | | Returns the name of the root file of this file system.
|
| hasCapability | | boolean hasCapability(Capability capability)(Code) | | Determines if this file system has a particular capability.

file - The file to remove the listener from.
Parameters:
listener - The listener to remove. |
