All Known Implementing Classes:

public interface ContinuousLine
A continuous line defines a line in an exact manner, from which numerical polylines can be derived. The continuous definition is useful to accurately connect different lines, e.g. based on the direction of the point where they meet. Moreover, this direction may be accurately be determined by either of the lines. For example, an arc can be defined up to a certain angle. Whatever the angle of the last line segment in a polyline for the arc may be, the continuous line contains the final direction exactly. The continuous definition is also useful to define accurate offset lines, which depend on accurate directions especially at the line end points.
