gmx::OptionValueConverterSimple< OutType > Class Template Reference

#include <gromacs/options/valueconverter.h>

Description

template<typename OutType>
class gmx::OptionValueConverterSimple< OutType >

Helper for converting from Variant to a given type.

Template Parameters
OutTypeType this converter converts to.

Default-constructed converter only supports identity mapping from the a Variant holding OutType. To add support for additional input types, provide conversion functions with addConverter(). To use a non-identity mapping for an OutType -> OutType conversion, provide an alternative conversion from OutType with addConverter().
