Description

Create a new shape of JavaFX Shape to be the combined area of its current shape and the shape of the specified Shape, minus their intersection.

Demo Code


//package com.java2s;

    /**/*from   w  w w .  ja v  a 2s.co m*/
     * Create a new shape of this <code>Shape</code> to be the combined area of
     * its current shape and the shape of the specified <code>Shape</code>,
     * minus their intersection. The resulting shape of this <code>Shape</code>
     * will include only areas that were contained in either this
     * <code>Shape</code> or in the specified <code>Shape</code>, but not in
     * both.

     *     a1.exclusiveOr(a2);
