template<typename CaseT , typename CaseT2 , typename... CaseTs, typename CallableT >

LLVM_ATTRIBUTE_ALWAYS_INLINE LLVM_ATTRIBUTE_NODEBUG DerivedT & llvm::detail::TypeSwitchBase< DerivedT, T >::Case ( CallableT &&  caseFn )

inline

Invoke a case on the derived class with multiple case types.

DerivedT & llvm::detail::TypeSwitchBase< DerivedT, T >::Case ( CallableT &&  caseFn )

inline

Invoke a case on the derived class, inferring the type of the Case from the first input of the given callable.
