Description

template<class T>
class gmx::RepeatingOptionSectionHandle< T >

Allows adding options to an RepeatingOptionSection.

An instance of this class is returned from IOptionsContainerWithSections::addSection(), and supports adding options and subsections to a section created with OptionSection.

Example:

struct SectionData { int value; }
// as class attribute
std::vector<SectionData> values;
void MyClass::initOptions(gmx::IOptionsContainerWithSections *options)
{
auto sec = options->addSection(gmx::RepeatingOptionSection<SectionData>("sec").storeVector(&values));
sec->addOption(gmx::IntegerOption("arg").store(&sec.bind().value));
}

Member Function Documentation

IOptionsContainer & gmx::AbstractOptionSectionHandle::addGroup ( )
overridevirtualinherited

Creates a subgroup of options within the current options.

To add options to the group, use the returned interface.

Currently, this is only used to influence the order of options: all options in a group appear before options in a group added after it, no matter in which order the options are added to the groups. In the future, the groups could also be used to influence the help output.

Implements gmx::IOptionsContainer.

template<class OptionType >
OptionType::InfoType* gmx::IOptionsContainer::addOption ( const OptionType &  settings)
inlineinherited

Adds a recognized option.

Template Parameters
OptionTypeType of the options description object.
Parameters
[in]settingsOption description.
Returns
OptionInfo object for the created option (never NULL).
Exceptions
APIErrorif invalid option settings are provided.

The return value is a pointer for more convenient use in callers: often callers need to declare the variable that will hold the return value in wider scope than would be achieved by declaring it at the site where addOption() is called. The returned pointer must not be freed.

See class documentation for example usage.

Examples:
template.cpp.
template<class SectionType >
SectionType::HandleType gmx::IOptionsContainerWithSections::addSection ( const SectionType &  section)
inlineinherited

Adds a section to this collection.

Template Parameters
SectionTypeType of the section description object.
Parameters
[in]sectionSection description.
Returns
AbstractOptionSectionHandle object for the created option.
Exceptions
APIErrorif invalid option settings are provided.

Options can be added to the section through the returned handle.
