void boost::program_options::abstract_variables_map::next

Sets next variable map, which will be used to find variables not found in *this.

const variable_value& boost::program_options::abstract_variables_map::operator[]

(

const std::string &

name

)

const

Obtains the value of variable 'name', from *this and possibly from the chain of variable maps.

• if there's no value in *this.
  • if there's next variable map, returns value from it
  • otherwise, returns empty value
• if there's defaulted value
  • if there's next varaible map, which has a non-defauled value, return that
  • otherwise, return value from *this
• if there's a non-defauled value, returns it.
