For instance, to specify a tiling restriction on a dimension with the form: [0, 2, 4, 5], the following code would apply: r_Dir_Decompose decomp; decomp << 0 << 2 << 4 << 5; Note that the first and the last elements input into the object must be the origin and limit of that dimension or else a cross-section of the domain will occur (as if the elements outside the specification wouldn't mind). If one dimension is considered to be a prefered access direction, then the r_Dir_Decompose should be empty, this is, no restriction should be entered. */ /** * \ingroup Rasodmgs */ class r_Dir_Decompose { public: r_Dir_Decompose(); virtual ~r_Dir_Decompose(); /// Copy constructor r_Dir_Decompose(const r_Dir_Decompose& other); /// Assigment operator const r_Dir_Decompose& operator=(const r_Dir_Decompose& other); /// Reads a new limit for the current dimension r_Dir_Decompose& operator<<(r_Range limit); /// Gets the number of intervals the dimension is to be split into int get_num_intervals() const; /// Gets a restriction r_Range get_partition(int number) const throw (r_Eindex_violation); /// Prints the current status of the object virtual void print_status(std::ostream& os = cout ) const; protected: r_Sinterval get_total_interval( ); /// Initial number of intervals of the buffer const static r_Dimension DEFAULT_INTERVALS; /// The number of intervals that this object can currently suport r_Dimension num_intervals; /// The current interval that is being used for input r_Dimension current_interval; /// The buffer that holds the information r_Range* intervals; }; //@ManMemo: Module: {\bf rasodmg} /** Prints the status of an r_Dir_Decompose object to a stream */ extern std::ostream& operator<<(std::ostream& os, const r_Dir_Decompose& d); extern std::ostream& operator<<(std::ostream& os, const std::vector& vec); #endif
