| // CLASS : sc_generic_base |
| // |
| // Proxy class for user-defined value classes and other classes that |
| // are defined outside of SystemC. |
| // The class is utilized as a base class for the arbitrary class: |
| // |
| // class my_class : public sc_generic_base<my_class> |
| // |
| // The purpose of the class is to allow to_XXXX methods defined within that |
| // class so that assignments and casts from the arbitrary class to native |
| // SystemC types are possible. To interact correctly with the SystemC library |
| // the class derived from sc_generic_base must implement the following |
| // methods: |
| // (1) uint64 to_uint64() const |
| // (2) int64 to_int64() const |
| // (3) void to_sc_unsigned( sc_unsigned& ) const |
| // (4) void to_sc_signed( sc_signed& ) const |
