C++Cast-class: Enumeration for types of C++ casting/coercion

In omegahat/RAutoGenRunTime: Run-time support for automated interfaces to R

Enumeration for types of C++ casting/coercion

Description

The C++Cast and C++CastValues provide the definition for a collection of related enumerated constants that allow the R programmer to identify different types of casting of C++ references to another class. There are four types of casting in C++ as opposed to just one in C. These are static, dynamic, reinterpret and const. These have different characteristics including run-time coercion rather than compile-time knowledge.

This class and EnumDef prvide the definitions so that we can use either the names or numerical values when idenifying a type of cast.
