Examples of java.awt.geom.Rectangle2D.intersectsLine()

java.awt.geom.Rectangle2D.intersectsLine()
Tests if the specified line segment intersects the interior of this Rectangle2D. @param x1 the X coordinate of the start point of the specifiedline segment @param y1 the Y coordinate of the start point of the specifiedline segment @param x2 the X coordinate of the end point of the specifiedline segment @param y2 the Y coordinate of the end point of the specifiedline segment @return true if the specified line segment intersectsthe interior of this Rectangle2D; false otherwise. @since 1.2

   * @param harness  the test harness (<code>null</code> not permitted).
