Method Detail
currentSegment
public int currentSegment(float[] coords)(Code)
Returns the coordinates and type of the current path segment in the iteration. The return value is the path segment type: SEG_MOVETO, SEG_LINETO, SEG_QUADTO, SEG_CUBICTO, or SEG_CLOSE. A float array of length 6 must be passed in and may be used to store the coordinates of the point(s). Each point is stored as a pair of float x,y coordinates. SEG_MOVETO and SEG_LINETO types will return one point, SEG_QUADTO will return two points, SEG_CUBICTO will return 3 points and SEG_CLOSE will not return any points.

See Also:   QuadIterator.SEG_QUADTO
See Also:   QuadIterator.SEG_CUBICTO
See Also:   QuadIterator.SEG_CLOSE



currentSegment
public int currentSegment(double[] coords)(Code)
Returns the coordinates and type of the current path segment in the iteration. The return value is the path segment type: SEG_MOVETO, SEG_LINETO, SEG_QUADTO, SEG_CUBICTO, or SEG_CLOSE. A double array of length 6 must be passed in and may be used to store the coordinates of the point(s). Each point is stored as a pair of double x,y coordinates. SEG_MOVETO and SEG_LINETO types will return one point, SEG_QUADTO will return two points, SEG_CUBICTO will return 3 points and SEG_CLOSE will not return any points.

getWindingRule
public int getWindingRule()(Code)
Return the winding rule for determining the insideness of the path.
See Also:   QuadIterator.WIND_EVEN_ODD
See Also:   QuadIterator.WIND_NON_ZERO



isDone
public boolean isDone()(Code)
Tests if there are more points to read. true if there are more points to read



next
public void next()(Code)
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.
