Constructor Details

PolygonIterator

public PolygonIterator(Polygon2D pl,
 AffineTransform at)

Create a new iterator over the given polygon and with the given transform. If the transform is null, that is taken to be the same as a unit Transform.

Method Details

currentSegment

public int currentSegment(double[] coords)

Get the current segment

Specified by:

currentSegment in interface PathIterator

currentSegment

public int currentSegment(float[] coords)

Get the current segment

Specified by:

getWindingRule

public int getWindingRule()

Return the winding rule. This is WIND_NON_ZERO.

Specified by:

getWindingRule in interface PathIterator

isDone

public boolean isDone()

Test if the iterator is done.

Specified by:

isDone in interface PathIterator

next

public void next()

Move the iterator along by one point.

Specified by:

next in interface PathIterator
