Range of indexed accessor iterators over a non‐indexable base.

Synopsis

Declared in <llvm/ADT/STLExtras.h>

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

Description

Ranges with offsetable bases 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.
