calculatesCrossingsPathIteratorPathShadow
static int calculatesCrossingsPathIteratorPathShadow(int crossings, PathIterator2afp<?> iterator, BasicPathShadow2afp shadow, CrossingComputationType type)
Accumulate the number of times the path crosses the shadow extending to the right of the second path. See the comment for the SHAPE_INTERSECTS constant for more complete details. The return value is the sum of all crossings for both the top and bottom of the shadow for every segment in the path, or the special value SHAPE_INTERSECTS if the path ever enters the interior of the rectangle. The path must start with a SEG_MOVETO, otherwise an exception is thrown. The caller must check r[xy]{min, max} for NaN values.- Parameters:
crossings
- is the initial value for crossing.iterator
- is the iterator on the path elements.shadow
- is the description of the shape to project to the right.type
- is the type of special computation to apply. Ifnull
, it is equivalent toCrossingComputationType.STANDARD
.- Returns:
- the crossings.

The direction it slides (to the "left" or to the "right") will be chosen to meet the criteria specified by the two boolean flags as described below. Only one direction will allow the method to meet both criteria.
- If the

@Pure default PathIterator2afp<IE> getPathIterator(double flatness)
Description copied from interface:Path2D
Replies an iterator on the path elements.Only
PathElementType.MOVE_TO
,PathElementType.LINE_TO

types are returned by the iterator.The amount of subdivision of the curved segments is controlled by the flatness parameter, which specifies the maximum distance that any point on the unflattened transformed curve can deviate from the returned flattened path segments. Note that a limit on the accuracy of the flattened path might be silently imposed, causing very small flattening parameters to be treated as larger values. This limit, if there is one, is defined by the particular implementation that is used.
The iterator for this class is not multi-threaded safe.
