---|---|
int |
currentSegment(double[] coords)
Returns the coordinates and type of the current path segment in the iteration.
|
int |
getWindingRule()
Return the winding rule for determining the interior of the path.
|
boolean |
isDone()
Tests if the iteration is complete.
|
void |
next()
Moves the iterator to the next segment of the path forwards along the primary direction of traversal as long as there are more points in that
direction.
