Class Arc2D.ArcIterator

java.lang.Object
  java.awt.geom.Arc2D.ArcIterator

All Implemented Interfaces:: PathIterator

Enclosing class:: Arc2D

static final class Arc2D.ArcIterator
extends java.lang.Object
implements PathIterator

This class is used to iterate over an arc. Since ellipses are a subclass of arcs, this is used by Ellipse2D as well.

Field Summary

private int current
          The current iteration.

private double extent
          The extent angle, in radians (not degrees).

private double h
          The height of the bounding box.

private int limit
          The last iteration.

private double start
          The start angle, in radians (not degrees).

private int type
          The arc closure type.

private double w
          The width of the bounding box.

private double x
          The x coordinate of the bounding box.

private AffineTransform xform
          The optional transformation.

private double y
          The y coordinate of the bounding box.

Constructor Summary

Arc2D.ArcIterator(Arc2D a, AffineTransform xform)
          Construct a new iterator over an arc.

Arc2D.ArcIterator(Ellipse2D e, AffineTransform xform)
          Construct a new iterator over an ellipse.

Method Summary

int currentSegment(double[] coords)
          Put the current segment into the array, and return the segment type.

int currentSegment(float[] coords)
          Put the current segment into the array, and return the segment type.

int getWindingRule()
          Return the winding rule.

boolean isDone()
          Test if the iteration is complete.

void next()
          Advance the iterator.
