Options Namespace Reference

Utilities for parsing input files. More...

Namespaces
namespace	AutoLabel
	The label representing the absence of a value for Options::Auto

Classes
struct	Alternatives
	Provide multiple ways to construct a class. More...
class	Auto
	A class indicating that a parsed value can be automatically computed instead of specified. More...
class	Comparator
	An option-creatable mathematical comparison. More...
struct	Context
	Information about the nested operations being performed by the parser, for use in printing errors. A default-constructed Context is printed as an empty string. This struct is primarily used as an argument to PARSE_ERROR for reporting input file parsing errors. Users outside of the core option parsing code should not need to manipulate the contents. More...
struct	create_from_yaml
	Used by the parser to create an object. The default action is to parse options using T::options. This struct may be specialized to change that behavior for specific types. More...

Typedef Documentation

add_factory_classes

template<typename FactoryClasses , typename... NewClasses>

using Options::add_factory_classes = typedef typename detail::add_factory_classes<FactoryClasses, NewClasses...>::type

Add new factory-creatable classes to the list in a factory_creation struct.

For each tmpl::pair<Base, DerivedList> in the NewClasses parameter pack, append the classes in DerivedList to the list for Base in FactoryClasses. The FactoryClasses map need not have a preexisting entry for Base.

This example adds three new derived classes, two for one base class and one for another.

using new_classes = Options::add_factory_classes<
    original_classes,
    tmpl::pair<Base<Label<0>>,
               tmpl::list<Derived<Label<3>>, Derived<Label<4>>>>,
    tmpl::pair<Base<Label<2>>, tmpl::list<Derived<Label<5>>>>>;
