That means that moving forward along the boundary is to travel in - * such a way that the interior of the shape is to the left of the outline path - * and the exterior of the shape is to the right of the outline path. The - * interior and exterior of the shape are determined by a winding rule. - * </p> - * - * @since Android 1.0 - */ -public interface PathIterator { - - /** - * The Constant WIND_EVEN_ODD indicates the winding rule that says that a - * point is outside the shape if any infinite ray from the point crosses the - * outline of the shape an even number of times, otherwise it is inside. - */ - public static final int WIND_EVEN_ODD = 0; - - /** - * The Constant WIND_NON_ZERO indicates the winding rule that says that a - * point is inside the shape if every infinite ray starting from that point - * crosses the outline of the shape a non-zero number of times. - */ - public static final int WIND_NON_ZERO = 1; - - /** - * The Constant SEG_MOVETO indicates that to follow the shape's outline from - * the previous point to the current point, the cursor (traversal point) - * should be placed directly on the current point. - */ - public static final int SEG_MOVETO = 0; - - /** - * The Constant SEG_LINETO indicates that to follow the shape's outline from - * the previous point to the current point, the cursor (traversal point) - * should follow a straight line. - */ - public static final int SEG_LINETO = 1; - - /** - * The Constant SEG_QUADTO indicates that to follow the shape's outline from - * the previous point to the current point, the cursor (traversal point) - * should follow a quadratic curve. - */ - public static final int SEG_QUADTO = 2; - - /** - * The Constant SEG_CUBICTO indicates that to follow the shape's outline - * from the previous point to the current point, the cursor (traversal - * point) should follow a cubic curve. - */ - public static final int SEG_CUBICTO = 3; - - /** - * The Constant SEG_CLOSE indicates that the previous point was the end of - * the shape's outline. - */ - public static final int SEG_CLOSE = 4; - - /** - * Gets the winding rule, either {@link PathIterator#WIND_EVEN_ODD} or - * {@link PathIterator#WIND_NON_ZERO}. - * - * @return the winding rule. - */ - public int getWindingRule(); - - /** - * Checks if this PathIterator has been completely traversed. - * - * @return true, if this PathIterator has been completely traversed. - */ - public boolean isDone(); - - /** - * Tells this PathIterator to skip to the next segment. - */ - public void next(); - - /** - * Gets the coordinates of the next vertex point along the shape's outline - * and a flag that indicates what kind of segment to use in order to connect - * the previous vertex point to the current vertex point to form the current - * segment. - * - * @param coords - * the array that the coordinates of the end point of the current - * segment are written into. - * @return the flag that indicates how to follow the shape's outline from - * the previous point to the current one, chosen from the following - * constants: {@link PathIterator#SEG_MOVETO}, - * {@link PathIterator#SEG_LINETO}, {@link PathIterator#SEG_QUADTO}, - * {@link PathIterator#SEG_CUBICTO}, or - * {@link PathIterator#SEG_CLOSE}. - */ - public int currentSegment(float[] coords); - - /** - * Gets the coordinates of the next vertex point along the shape's outline - * and a flag that indicates what kind of segment to use in order to connect - * the previous vertex point to the current vertex point to form the current - * segment. - * - * @param coords - * the array that the coordinates of the end point of the current - * segment are written into. - * @return the flag that indicates how to follow the shape's outline from - * the previous point to the current one, chosen from the following - * constants: {@link PathIterator#SEG_MOVETO}, - * {@link PathIterator#SEG_LINETO}, {@link PathIterator#SEG_QUADTO}, - * {@link PathIterator#SEG_CUBICTO}, or - * {@link PathIterator#SEG_CLOSE}. - */ - public int currentSegment(double[] coords); - -} |
