Usage

From source file:ClassComparator.java

 * Checks, whether the given classes are comparable. This method will return
 * true, if one of the classes is assignable from the other class.

 * @param c2
 *          the second class to compare
 * @return true, if the classes share a direct relation, false otherwise.
