fcppt::parse::base< Result, Ch, Skipper > Class Template Reference

Detailed Description

template<typename Result, typename Ch, typename Skipper>
class fcppt::parse::base< Result, Ch, Skipper >

Base class for a parser.

The type of a parser usually gets very complicated because it depends on all of its subparsers. In case we want to declare a parser as a member of a class for example, we want to use a simpler type. This is achieved by using fcppt::parse::make_base to create a parser of type base. The employed technique is also known as type erasure.
