Usage

From source file:Main.java

/**
 * Check if two Drawables are equal. A regular check for a Drawable equals
 * just checks for the instance reference, while this check is doing a
 * deeper equals when dealing with {@link DrawableContainer} instances. In
 * these cases, the method will run equals on each of the child drawables in
 * the container (order is importance as well).
 * // w  w  w.  j  a  v a 2s  .  c  om
 * @param d1
 * @param d2
 * @return <code>true</code> if the drawables are equal, <code>false</code>
 *         otherwise.
