template<class Base, class Derived, class TypeClass, class LocalData>
class clang::ConcreteTypeLoc< Base, Derived, TypeClass, LocalData >

A metaprogramming base class for [TypeLoc](classclang%5F1%5F1TypeLoc.html "Base wrapper for a particular "section" of type source info.") classes which correspond to a particular Type subclass.

It is accepted for a single [TypeLoc](classclang%5F1%5F1TypeLoc.html "Base wrapper for a particular "section" of type source info.") class to correspond to multiple Type classes.

Template Parameters

Base	a class from which to derive
Derived	the class deriving from this one
TypeClass	the concrete Type subclass associated with this location type
LocalData	the structure type of local location data for this type

TypeLocs with non-constant amounts of local data should override getExtraLocalDataSize(); getExtraLocalData() will then point to this extra memory.

TypeLocs with an inner type should define QualType getInnerType() const and getInnerTypeLoc() will then point to this inner type's location data.

A word about hierarchies: this template is not designed to be derived from multiple times in a hierarchy. It is also not designed to be used for classes where subtypes might provide different amounts of source information. It should be subclassed only at the deepest portion of the hierarchy where all children have identical source information; if that's an abstract type, then further descendents should inherit from InheritingConcreteTypeLoc instead.
