Detailed Description

template<typename DerivedT, typename BaseT, typename T, typename PointerT = T *, typename ReferenceT = T &>
class llvm::indexed_accessor_range< DerivedT, BaseT, T, PointerT, ReferenceT >

This class provides an implementation of a range of indexed_accessor_iterators where the base is not indexable.

Ranges with bases that are offsetable should derive from indexed_accessor_range_base instead. Derived range classes are expected to implement the following static method:

• ReferenceT dereference(const BaseT &base, ptrdiff_t index)
  • Dereference an iterator pointing to a parent base at the given index.
