11.2 OEGetDataType

template<class T> const void *OEGetDataType()

This template function provides a convenient and efficient mechanism for run-time type identification (RTTI). A unique const void pointer is returned for each requested data type. Template classes which derive from a base class which has a data type identification interface can then be resolved by comparisons to data types returned by the OEGetDataType template function. Type comparisons are valid across compile units. Run-time type identification using this function is likely to be more efficient than built-in C++ RTTI.
