Method Detail

compare

public int compare(Object o1,
                   Object o2)

Compares two Class values in terms of specificity; the more specific class is said to be "smaller" than the more generic one hence the Object class is the "largest" possible class. When two classes are not comparable (i.e. not assignable from each other) in either direction a NotComparableException will be thrown. both input objects should be Class values otherwise a ClassCastException will be thrown.
