Member Function Documentation

template<typename T >

accumulator_type* accumulator_type< T >::implicit_value ( const T & t )

inline

Set the implicit value for this option.

Unlike for program_options::value, this specifies a value to be applied on each occurrence of the option.

Definition at line 39 of file accumulator.h.

template<typename T >

virtual void accumulator_type< T >::parse	(	boost::any &	value_store,
		const std::vector< std::string > &	,
		bool
	)		const

inlinevirtual

Every appearance of the option simply increments the value.

There should never be any tokens.
