Definition: zconf.h:214

This macro provides a quick way to define a static function called classname() which returns the provided class name as a string.

#define DECLARE_DATAFACTORY (   DataClass,
  SuperClass,
  Description,
  DopParms 
)

This macro simplifies the calling and casting the return value from This macro quickly defines all the static functions needed to declare a SIM_DataFactory for a SIM_Data subclass.

protected: \
void *getCastToType(const UT_StringRef &totype) const override \
{ \
if( classname() == totype ) \
return (void *)this; \
return BaseClass::getCastToType(totype); \

This function implements a standard version of getDistanceToType(). Only if your subclass uses multiple inheritance will it be necessary to write a customized version of this function. Be sure to add this declaration to your class definition or the DECLARE_DATAFACTORY() macro will not compile properly.

Definition at line 50 of file SIM_DataUtils.h.

#define IMPLEMENT_DATAFACTORY (   DataClass)
Value:
static SIM_DataFactoryCreator \
DataClass##Creator(DataClass::createDataFactory);

Add this macro to the initialization function for your library. It uses the declaration above to register your data type.

Examples:
SIM/GAS_NetVDBSliceExchange.C, SIM/SIM_ElectricalProperties.C, SIM/SIM_ForceOrbit.C, SIM/SIM_GasAdd.C, SIM/SIM_RadialEmit.C, SIM/SIM_SolverHair.C, and SIM/SNOW_Solver.C.
