Member Function Documentation

get_help()

virtual std::vector<std::pair<std::string, std::string> > vg::subcommand::BaseOptionGroup::get_help ( ) const

pure virtual

Get help, in the form of pairs of options and descriptions. Headings are descriptions without options.

Implemented in vg::subcommand::GroupedOptionGroup, and vg::subcommand::OptionGroup< Receiver >.

get_option_value()

template<typename T >

T vg::subcommand::BaseOptionGroup::get_option_value ( const std::string &  option ) const

inline

Allow the user to query an option value by name. Would be simpler if we could override template methods but we can't.

make_long_options()

virtual void vg::subcommand::BaseOptionGroup::make_long_options ( std::vector< struct option > &  dest ) const

pure virtual

Add options to non-null-terminated input for getopt_long.

Implemented in vg::subcommand::GroupedOptionGroup, and vg::subcommand::OptionGroup< Receiver >.

make_short_options()

virtual void vg::subcommand::BaseOptionGroup::make_short_options ( std::string &  dest ) const

pure virtual

Add options to string input for getopt_long.

Implemented in vg::subcommand::GroupedOptionGroup, and vg::subcommand::OptionGroup< Receiver >.

parse()

virtual bool vg::subcommand::BaseOptionGroup::parse ( int  option_id, const char *  optarg  )

pure virtual

Parse the given option ID, with the given value if needed. Return true if we matched the ID, and false otherwise.

Implemented in vg::subcommand::GroupedOptionGroup, and vg::subcommand::OptionGroup< Receiver >.

preset()

virtual bool vg::subcommand::BaseOptionGroup::preset ( const BaseValuation &  entry )

pure virtual

Apply a preset value to its option. Returns true if it was found, and false otherwies.

Implemented in vg::subcommand::GroupedOptionGroup, and vg::subcommand::OptionGroup< Receiver >.

print_options()

virtual void vg::subcommand::BaseOptionGroup::print_options ( ostream &  out, OptionFormat  format = OptionFormat::CLI  ) const

pure virtual

Print all options set, in the given format.

Implemented in vg::subcommand::GroupedOptionGroup, and vg::subcommand::OptionGroup< Receiver >.

query()

virtual bool vg::subcommand::BaseOptionGroup::query ( BaseValuation &  entry ) const

pure virtual

Fill in entry with the value of the correspondign option, if we have that option. If so, return true.

Implemented in vg::subcommand::GroupedOptionGroup, and vg::subcommand::OptionGroup< Receiver >.

set()

virtual bool vg::subcommand::BaseOptionGroup::set ( const BaseValuation &  entry )

pure virtual

Apply a value to its option. Returns true if it was found, and false otherwies.

Implemented in vg::subcommand::GroupedOptionGroup, and vg::subcommand::OptionGroup< Receiver >.

set_option_value()

template<typename T >

void vg::subcommand::BaseOptionGroup::set_option_value ( const std::string &  option, const T &  value  )

inline

Allow the user to manually set an option value.
