clang: clang::LazyGenerationalUpdatePtr< Owner, T, Update (original) (raw)

A lazy value (of type T) that is within an AST node of type Owner, where the value might change in later generations of the external AST source. More...

Classes
struct	LazyData
	A cache of the value of this pointer, in the most recent generation in which we queried it. More...

Public Types
enum	NotUpdatedTag { NotUpdated }
	Create a pointer that is not potentially updated by later generations of the external AST source. More...
