jdk.awt.geom.FlatteningPathIterator
The FlatteningPathIterator class returns a flattened view of another PathIterator object. Other Shape classes can use this class to provide flattening behavior for their paths without having to perform the interpolation calculations themselves.

->flattening-path-iteratorclj
(->flattening-path-iterator src flatness)(->flattening-path-iterator src flatness limit)Constructor.
Constructs a new FlatteningPathIterator object that flattens a path as it iterates over it. The limit parameter allows you to control the maximum number of recursive subdivisions that the iterator can make before it assumes that the curve is flat enough without measuring against the flatness parameter. The flattened iteration therefore never generates more than a maximum of (2^limit) line segments per curve.
src - the original unflattened path being iterated over - java.awt.geom.PathIterator
flatness - the maximum allowable distance between the control points and the flattened curve - double
limit - the maximum number of recursive subdivisions allowed for any curved segment - int
throws: java.lang.IllegalArgumentException - if flatness or limit is less than zero

current-segmentclj
(current-segment this coords)Returns the coordinates and type of the current path segment in the iteration. The return value is the path segment type: SEG_MOVETO, SEG_LINETO, or SEG_CLOSE. A float array of length 6 must be passed in and can be used to store the coordinates of the point(s). Each point is stored as a pair of float x,y coordinates. SEG_MOVETO and SEG_LINETO types return one point, and SEG_CLOSE does not return any points.
coords - an array that holds the data returned from this method - float[]
returns: the path segment type of the current path segment. - int
throws: java.util.NoSuchElementException - if there are no more elements in the flattening path to be returned.

done?clj
(done? this)Tests if the iteration is complete.
returns: true if all the segments have
been read; false otherwise. - boolean

get-flatnessclj
(get-flatness this)Returns the flatness of this iterator.

returns: the recursion limit of this
FlatteningPathIterator. - int
Returns the recursion limit of this iterator. returns: the recursion limit of this FlatteningPathIterator. - `int`
get-winding-ruleclj
(get-winding-rule this)Returns the winding rule for determining the interior of the path.
returns: the winding rule of the original unflattened path being
iterated over. - int

nextclj
(next this)Moves the iterator to the next segment of the path forwards along the primary direction of traversal as long as there are more points in that direction.
