Detailed Description

template<class ProjectInterface = HGL::Type::IProject, class Factory = HGL::Type::IProjectFactory>
interface HGL::Common::IParser< ProjectInterface, Factory >

Interface to a parsing subsystem.

This interface provides methods needed for HGL::Common::createProject Concrete subclasses should implement a parser, which returns the ProjectInterface as root of the type tree and use Factory to create the types.
