Detailed Description

template<typename T, typename Source, void(Source::*)(SmallVectorImpl< T > &) Loader, unsigned LoadedStorage = 2, unsigned LocalStorage = 4>
class clang::LazyVector< T, Source, Loader, LoadedStorage, LocalStorage >::iterator

Iteration over the elements in the vector.

In a complete iteration, the iterator walks the range [-M, N), where negative values are used to indicate elements loaded from the external source while non-negative values are used to indicate elements added via push_back(). However, to provide iteration in source order (for, e.g., chained precompiled headers), dereferencing the iterator flips the negative values (corresponding to loaded entities), so that position -M corresponds to element 0 in the loaded entities vector, position -M+1 corresponds to element 1 in the loaded entities vector, etc. This gives us a reasonably efficient, source-order walk.

We define this as a wrapping iterator around an int. The iterator_adaptor_base class forwards the iterator methods to basic integer arithmetic.
