Detailed Description

template<typename ThisT, typename ParentT>
class llvm::RTTIExtends< ThisT, ParentT >

Inheritance utility for extensible RTTI.

Supports single inheritance only: A class can only have one ExtensibleRTTI-parent (i.e. a parent for which the isa<> test will work), though it can have many non-ExtensibleRTTI parents.

RTTIExtents uses CRTP so the first template argument to RTTIExtends is the newly introduced type, and the second argument is the parent class.

class MyType : public RTTIExtends<MyType, RTTIRoot> { public: static char ID; };

class MyDerivedType : public RTTIExtends<MyDerivedType, MyType> { public: static char ID; };
