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