Performs an equality test based on a point on this line defined
by
k as in getPoint(double) and another given
point. |
boolean |
equals(Object o)
Overridden to reflect equality of abstract values (data object) as
opposite to object identity.
|
PlanePoint |
getPoint(double k)
Returns the point of this line defined by
k . |
