getFileSystemsMounted

public int getFileSystemsMounted()

Description copied from interface: JmxManagerMXBean

Returns the number of file systems which have been mounted.

Note that you should not use the returned value to synchronize conditionally - this would be unreliable!

Specified by:

getFileSystemsMounted in interface JmxManagerMXBean

Returns:

The number of mounted file systems.

getFileSystemsTotal

public int getFileSystemsTotal()

Description copied from interface: JmxManagerMXBean

Returns the total number of file systems.

Specified by:

getFileSystemsTotal in interface JmxManagerMXBean

Returns:

The total number of file systems.

getTopLevelArchiveFileSystemsMounted

public int getTopLevelArchiveFileSystemsMounted()

Description copied from interface: JmxManagerMXBean

Returns the number of top level archive file systems which have been mounted. The value of this property never exceeds JmxManagerMXBean.getFileSystemsMounted().

Note that you should not use the returned value to synchronize conditionally - this would be unreliable!

Specified by:

getTopLevelArchiveFileSystemsMounted in interface JmxManagerMXBean

Returns:

The number of mounted top level archive file systems.

getTopLevelArchiveFileSystemsTotal

public int getTopLevelArchiveFileSystemsTotal()

Description copied from interface: JmxManagerMXBean

Returns the total number of top level archive file systems. The value of this property never exceeds JmxManagerMXBean.getFileSystemsTotal().

Specified by:

getTopLevelArchiveFileSystemsTotal in interface JmxManagerMXBean

Returns:

The total number of top level archive file systems.

sync

public void sync()
          throws FsSyncException

Description copied from interface: JmxManagerMXBean

Synchronizes all file systems and eventually unmounts them. As a side effect, upon successful operation, the value of the property fileSystemsMounted is reset to zero unless some mounted file systems retain elements in their selective entry cache.

Specified by:

sync in interface JmxManagerMXBean

Throws:

FsSyncWarningException - if only warning conditions apply. This implies that the respective parent file system has been synchronized with constraints, e.g. if an unclosed archive entry stream gets forcibly closed.

FsSyncException - if any error conditions apply.
