Method Detail

compare

public int compare(Object o1,
                   Object o2)

Compares this object with the specified object for order. Returns a negative integer, zero, or a positive integer if the first argument is less than, equal to, or greater than the specified object. The SubInfo are compared by their transformation name. This implementation is not consistent with the SubInfo.equals(Object) method. Hence, should not be used in sorted Sets or Maps.

Specified by:

compare in interface Comparator

Parameters:

o1 - is the first object to be compared.

o2 - is the second object to be compared.

Returns:

a negative number, zero, or a positive number, if the object compared against is less than, equals or greater than this object.

Throws:

ClassCastException - if the specified object's type prevents it from being compared to this Object.
