Abstract interface for the extrapolation of a helix to the closest approach to a line.

| typedef Basic3DVector<float> HelixLineExtrapolation::PositionType |
The types for position and direction are frame-neutral (not global, local, etc.) so this interface can be used in any frame. Of course, the helix and the plane must be defined in the same frame, which is also the frame of the result.

pure virtual |
Returns the direction along the helix that corresponds to path length "s" from the starting point. As for position, the direction at the closest approach (if it exists!) is given by direction( pathLength(line) ).
Implemented in HelixExtrapolatorToLine2Order, and IterativeHelixExtrapolatorToLine.
|
pure virtual |
Propagation status (true if valid) and (signed) path length along the helix from the starting point to the closest approach to the point. The starting point is given in the constructor.
Implemented in HelixExtrapolatorToLine2Order, and IterativeHelixExtrapolatorToLine.

|
pure virtual |
Returns the position along the helix that corresponds to path length "s" from the starting point. If s is obtained from the pathLength method the position is the destination point, i.e. the position at the closest approach (if it exists!) is given by position( pathLength(line) ).
Implemented in HelixExtrapolatorToLine2Order, and IterativeHelixExtrapolatorToLine.
