Document

Returns an iterator object that iterates along the Shape boundary and provides access to a flattened view of the Shape outline geometry.

Usage

From source file:Main.java

public static void main(String[] args) throws Exception {
    Shape s = new Rectangle2D.Double(0, 0, 72, 72);

    PathIterator pi = s.getPathIterator(null, 2);

    while (pi.isDone() == false) {
        describeCurrentSegment(pi);//from w  w w  . ja  va2 s . com
        pi.next();
    }

}
