delegate

protected final M extends FsManager delegate

FsDecoratingManager

protected FsDecoratingManager(@NonNull
                              M manager)

Constructs a new decorating file system manager.

Parameters:

manager - the decorated file system manager.

getController

public FsController<?> getController(FsMountPoint mountPoint,
                                     FsCompositeDriver driver)

Description copied from class: FsManager

Returns a thread-safe file system controller for the given mount point. If and only if the given mount point addresses a federated file system, the returned file system controller is remembered for life cycle management, i.e. future lookup and synchronization operations.

Specified by:

getController in class FsManager

Parameters:

mountPoint - the mount point of the file system.

driver - the file system composite driver which will be used to create a new file system controller if required.

Returns:

A file system controller.

getSize

public int getSize()

Description copied from class: FsManager

Returns the number of federated file systems managed by this instance.

Specified by:

getSize in class FsManager

Returns:

The number of federated file systems managed by this instance.

iterator

public Iterator<FsController<?>> iterator()

Description copied from class: FsManager

Returns an iterator for the controller of all federated file systems managed by this instance.

Important: The iterated file system controllers must be ordered so that all file systems appear before any of their parent file systems.

Specified by:

iterator in interface Iterable<FsController<?>>

Specified by:

iterator in class FsManager

Returns:

An iterator for the controller of all federated file systems managed by this instance.

sync

public <X extends IOException> void sync(BitField<FsSyncOption> options,
                                         ExceptionHandler<? super IOException,X> handler)
          throws X extends IOException

Description copied from class: FsManager

Commits all unsynchronized changes to the contents of all federated file systems managed by this instance to their respective parent file system. This will reset the state of the respective file system controllers.

Overrides:

sync in class FsManager

Type Parameters:

X - the type of the IOException to throw at the discretion of the exception handler.

Parameters:

options - the synchronization options.

handler - the exception handling strategy for dealing with one or more input SyncExceptions which may trigger an X.

Throws:

X extends IOException

toString

public String toString()

Returns a string representation of this object for debugging and logging purposes.

Overrides:

toString in class FsManager
