Detailed Description

template<class Delimiter, class OutputBuffer>
class folly::gen::detail::UnsplitBuffer< Delimiter, OutputBuffer >

UnsplitBuffer - For joining tokens from a generator into a string, and inserting them into a custom buffer.

This type is primarily used through the 'unsplit' function.
