Options Namespace Reference

Utilities for parsing input files. More...


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


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...

 Option parser tag to retrieve the YAML source and all applied overlays. This tag can be requested without providing it as a template parameter to the Parser. More...

 Class that handles parsing an input file. More...

◆ 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<
tmpl::list<Derived<Label<3>>, Derived<Label<4>>>>,
tmpl::pair<Base<Label<2>>, tmpl::list<Derived<Label<5>>>>>;
typename detail::add_factory_classes< FactoryClasses, NewClasses... >::type add_factory_classes
Add new factory-creatable classes to the list in a factory_creation struct.
