typename SuperClass::const_iterator const_iterator

This is a 'vector' (really, a variable-sized array), optimized for the case when the array is small.

StringRef - Represent a constant reference to a string, i.e.

constexpr StringRef substr(size_t Start, size_t N=npos) const

Return a reference to the substring from [Start, Start + N).

A range adaptor for a pair of iterators.

This class implements an extremely fast bulk output stream that can only output to a stream.

This provides a very simple, boring adaptor for a begin and end iterator into a range type.
