Method Detail

isMounted

public boolean isMounted()

Description copied from interface: FsModel

Returns true if and only if some state associated with the federated file system has been modified so that the corresponding FsController must not get discarded until the next call to sync.

An implementation may always return false if the associated file system controller is stateless.

Returns:

true if and only if some state associated with the federated file system has been modified so that the corresponding FsController must not get discarded until the next sync.

setMounted

public void setMounted(boolean touched)

Description copied from interface: FsModel

Sets the value of the property mounted. Only file system controllers should call this method in order to register themselves for a call their FsController.sync(net.java.truecommons.shed.BitField<net.java.truevfs.kernel.spec.FsSyncOption>) method.

An implementation may ignore calls to this method if the associated file system controller is stateless.

Parameters:

touched - the new value of this property.

toString

public String toString()

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

Overrides:
