Member Function Documentation

◆ assignAnyEnum()

std::any assignAnyEnum ( const std::string &  tag) const
overridevirtual

Derived class overrides this to get proper assignment of scoped enum values.

In most cases all you'll need it to define the map and write: std::any DerivedInputSection::assignAnyEnum(const std::string& name) const { return lookupAnyEnum(name, get<std::string>(name), derived_input_lookup_enum); }

See test_InputSection.cpp and OneBodyDensityMatricesInput You really should do this if your input class has a finite set of string values for an input example: OneBodyDensityMatricesInput

can't be bothered then just define your enum option as a string.

Reimplemented from InputSection.

◆ checkParticularValidity()

void checkParticularValidity ( )
overridevirtual

Do validation for a particular subtype of InputSection Called by check_valid.

Default implementation is noop The InputSection subtype should make all correctness checks reasonable at parse time.
