28 * \brief Base class for all operations
30 * Base class for all operations. If you perform an action it is reasonable to create
31 * operation intended for this. This is a base class for all operations which provides
32 * mechanism for correct starting operations, starting operations above already started
33 * ones, committing operations and so on. To create own operation it is reasonable to
34 * inherit it from this class and redefines virtual methods to provide own behavior
35 * Main virtual methods are
36 * - virtual bool isReadyToStart();
37 * - virtual void startOperation();
38 * - virtual void abortOperation();
39 * - virtual void commitOperation();
