Usage

From source file:Main.java

 * the given {@link Object}, the method returns {@code true}.
 *
 * @param collection The collection to iterate recursively.
 * @param o          The object to look for in the collection.
 *
 * @return {@code true} if the object was found anywhere within the collection or any of its sub-collections.
