It is // very simple to use. Create a new MComputation object and call the // beginComputation method at the beginning of the computation and call // the endComputation method when you finish. Then, during the computation, // use the isInterruptRequested method to check if the user has requested // that the computation terminate. // // Example: // // MComputation computation; // computation.beginComputation(); // for (int i= 1; i<1000; i++) { // Computation(); // Some expensive operation // if (computation.isInterruptRequested()) break ; // } // computation.endComputation(); // // // ***************************************************************************** #if defined __cplusplus // ***************************************************************************** // INCLUDED HEADER FILES #include // ***************************************************************************** // FORWARD DECLARATIONS // ***************************************************************************** // CLASS DECLARATION (MComputation) /// Interupt monitor for long computations /** An MComputation is used to monitor user-interupts during int computations. */ #if defined(_WIN32) #pragma warning(disable: 4522) #endif // _WIN32 class OPENMAYA_EXPORT MComputation { public: /// MComputation(); /// virtual ~MComputation(); /// void beginComputation(); /// bool isInterruptRequested(); /// void endComputation(); protected: // No protected members private: const char* className() const; void *f_data; }; #if defined(_WIN32) #pragma warning(default: 4522) #endif // _WIN32 // ***************************************************************************** #endif /* __cplusplus */ #endif /* _MComputation */
