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