Method Detail

compare

public int compare(T instance1,
                   T instance2)

Specified by:

compare in interface java.util.Comparator<T>

compareInstances

protected abstract int compareInstances(T instance1,
                                        T instance2)

Implement method to perform the comparison. The instances passed are different and neither is null.

Parameters:

instance1 - first instance

instance2 - second instance

Returns:

return one of BEFORE, EQUAL, or AFTER.
