Method Detail

compare

public int compare(Object o1,
                   Object o2)
            throws ClassCastException

Compares two Objects for equality, but only when both Objects are in fact Fields. Each Field's getDeclaringClass() and getName() methods are called, and their String representations concatenated. The resulting Strings are compared to each other using the String.compareTo(java.lang.String) method, and its result is returned.

Specified by:

Parameters:

o1 - the first Field

o2 - the second Field

Returns:

-1 if o1 < o2, 0 if o1 == o2 or 1 if o1 > o2

Throws:
