int |
currentSegment(float[] coords)
Returns the coordinates and type of the current path segment in the iteration. |
double |
getMaxDistance()
Returns the distance limit for point skipping during distance based generalization |
int |
getWindingRule()
Returns 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. |
