template<class numeric_type >

line< numeric_type > geometric::line< numeric_type >::operator+

(

const point< numeric_type > &

to_add

)

const

Definition at line 101 of file line.h.

operator+=()

template<class numeric_type >

line< numeric_type > & geometric::line< numeric_type >::operator+=

(

to_subtract

)

Adds or subtracts a point from ‘this’ line.

Definition at line 96 of file line.h.

text_form()

template<class numeric_type >

basis::astring geometric::line< numeric_type >::text_form

returns a string form of the points defining the line.

Definition at line 84 of file line.h.

References basis::astring::text_form().
