Usage

From source file:RectUtils.java

/**
 * Unions the pair of source <code>Rectangle2D</code> objects and puts the
 * result into the returned <code>Rectangle2D</code> object. This method
 * extends the Rectangle2D version by checking for null parameters, the
 * returned value will also be <code>null</code> if the two input
 * rectangles are <code>null</code>
 * /*  ww w  .ja v a2 s .  c  om*/
