fcppt::parse::convert_if< Ch, Parser, Result > Class Template Reference

Detailed Description

template<typename Ch, typename Parser, typename Result>
class fcppt::parse::convert_if< Ch, Parser, Result >

Converts the success value of a parser into either another success value or an error.

If the parser p returns s, then convert(p,f) returns f(s), which can either be a success or an error value. Errors returned by p remain unchanged.

Template Parameters

Result

The success type of this parser.
