Constructor Detail
AffineLine()Constructor
public function AffineLine(p1:YPoint, p2:YPoint, init:Boolean = true)

Creates an affine line which is defined by two points.

Parameters
p1:YPoint
 
p2:YPoint
 
init:Boolean (default = true) — An internally used switch to help handle proper instance initialization in inheritance chains where classes can have multiple constructor-like factory methods. This parameter can safely be ignored/omitted when calling the constructor.
