Field Detail

• statistics

  private volatile FsStatistics statistics

Constructor Detail

• FsStatisticsManager

  public FsStatisticsManager(@NonNull
                     FsManager manager)

  Constructs a new statistics file system manager.

  Parameters:

  manager - the decorated file system manager.

Method Detail

• 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.

  Overrides:

  getController in class FsDecoratingManager<FsManager>

  Parameters:

  mountPoint - the mount point of the file system.

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

  Returns:

  A thread-safe file system controller for the given mount point.

• getStatistics

  @NonNull
  public FsStatistics getStatistics()

  Returns statistics about the set of federated file systems managed by the decorated file system manager. The statistics provided by the returned object get asynchronously updated up to the next call to sync(de.schlichtherle.truezip.util.BitField<de.schlichtherle.truezip.fs.FsSyncOption>, de.schlichtherle.truezip.util.ExceptionHandler<? super java.io.IOException, X>).

  Note that there may be a slight delay until the values returned reflect the actual state of this package. This delay increases if the system is under heavy load.

  sync(de.schlichtherle.truezip.util.BitField<de.schlichtherle.truezip.fs.FsSyncOption>, de.schlichtherle.truezip.util.ExceptionHandler<? super java.io.IOException, X>), FsStatistics.isClosed()

• sync

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

  Commits all unsynchronized changes to the contents of all federated file systems managed by this instance to their respective parent file system, releases the associated resources (e.g. target archive files) for access by third parties (e.g. other processes), cleans up any temporary allocated resources (e.g. temporary files) and purges any cached data. Note that temporary resources may get allocated even if the federated file systems were accessed read-only. As a side effect, this will reset the state of the respective file system controllers.

  After the synchronization, this implementation creates a new statistics object to be returned by a subsequent call to getStatistics().

  Overrides:

  sync in class FsManager

  Type Parameters:

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

  Parameters:

  options - a bit field of synchronization options.

  handler - the exception handling strategy for consuming input IOExceptions and/or assembling output IOExceptions.

  Throws:

  X extends IOException
