◆ convertTo()

template<typename T>
REPL_BUILTIN_TYPES T clang::Value::convertTo ( ) const

Get the value with cast.

Get the value cast to T. This is similar to reinterpret_cast<T>(value), casting the value of builtins (except void), enums and pointers. Values referencing an object are treated as pointers to the object.
