Interface ExtendedPathIterator

    public interface ExtendedPathIterator

The `ExtendedPathIterator` class represents a geometric path constructed from straight lines, quadratic and cubic (Bezier) curves and elliptical arcs. This interface is identical to that of PathIterator except it can return SEG_ARCTO from currentSegment, also the array of values passed to currentSegment must be of length 7 or an error will be thrown. This does not extend PathIterator as it would break the interface contract for that class.

Field Summary
`static int` | `SEG_ARCTO` The segment type constant for an elliptical arc.
`static int` | `SEG_CLOSE` The segment type constant that specifies that the preceding subpath should be closed by appending a line segment back to the point corresponding to the most recent SEG_MOVETO.
`static int` | `SEG_CUBICTO` The segment type constant for the set of 3 points that specify a cubic parametric curve to be drawn from the most recently specified point.
`static int` | `SEG_LINETO` The segment type constant for a point that specifies the end point of a line to be drawn from the most recently specified point.
`static int` | `SEG_MOVETO` The segment type constant for a point that specifies the end point of a line to be drawn from the most recently specified point.
`static int` | `SEG_QUADTO` The segment type constant for the pair of points that specify a quadratic parametric curve to be drawn from the most recently specified point.
`static int` | `WIND_EVEN_ODD` The winding rule constant for specifying an even-odd rule for determining the interior of a path.
`static int` | `WIND_NON_ZERO` The winding rule constant for specifying a non-zero rule for determining the interior of a path.

Method Summary
`int` | `currentSegment()`
`int` | `currentSegment(double[] coords)`
`int` | `currentSegment(float[] coords)`
`int` | `getWindingRule()`
`boolean` | `isDone()`
`void` | `next()`

Field Detail

### SEG_CLOSE

    static final int SEG_CLOSE

  The segment type constant that specifies that the preceding subpath should be closed by appending a line segment back to the point corresponding to the most recent SEG_MOVETO.

    Constant Field Values

### SEG_MOVETO

    static final int SEG_MOVETO

  The segment type constant for a point that specifies the end point of a line to be drawn from the most recently specified point.

  See Also:
    Constant Field Values

### SEG_LINETO

    static final int SEG_LINETO

  The segment type constant for a point that specifies the end point of a line to be drawn from the most recently specified point.

  See Also:
    Constant Field Values

### SEG_QUADTO

    static final int SEG_QUADTO

  The segment type constant for the pair of points that specify a quadratic parametric curve to be drawn from the most recently specified point. The curve is interpolated by solving the parametric control equation in the range (t=[0..1]) using the most recently specified (current) point (CP), the first control point (P1), and the final interpolated control point (P2).

  See Also:
    Constant Field Values

### SEG_CUBICTO

    static final int SEG_CUBICTO

  The segment type constant for the set of 3 points that specify a cubic parametric curve to be drawn from the most recently specified point. The curve is interpolated by solving the parametric control equation in the range (t=[0..1]) using the most recently specified (current) point (CP), the first control point (P1), the second control point (P2), and the final interpolated control point (P3).

  See Also:
    Constant Field Values

### SEG_ARCTO

    static final int SEG_ARCTO

  The segment type constant for an elliptical arc. This consists of Seven values [rx, ry, angle, largeArcFlag, sweepFlag, x, y]. rx, ry are the radious of the ellipse. angle is angle of the x axis of the ellipse. largeArcFlag is zero if the smaller of the two arcs are to be used. sweepFlag is zero if the 'left' branch is taken one otherwise. x and y are the destination for the ellipse.

  See Also:
    Constant Field Values

### WIND_EVEN_ODD

    static final int WIND_EVEN_ODD

  The winding rule constant for specifying an even-odd rule for determining the interior of a path. The even-odd rule specifies that a point lies inside the path if a ray drawn in any direction from that point to infinity is crossed by path segments an odd number of times.

  See Also:
    Constant Field Values

### WIND_NON_ZERO

    static final int WIND_NON_ZERO

  The winding rule constant for specifying a non-zero rule for determining the interior of a path. The non-zero rule specifies that a point lies inside the path if a ray drawn in any direction from that point to infinity is crossed by path segments a different number of times in the counter-clockwise direction than the clockwise direction.

  See Also:
    Constant Field Values
