Method Detail

predecessor

boolean predecessor(E o1,
                    E o2)

Returns true if o1 is an immediate predecessor of o2.

Parameters:

o1 - a sequence element.

o2 - a sequence element.

Returns:

true if its an immediate predecessor

successor

boolean successor(E o1,
                  E o2)

Returns true if o1 is an immediate successor of o2.

Parameters:

o1 - a sequence element.

o2 - a sequence element.

Returns:

true if its an immediate successor

isValid

boolean isValid(E o1)

Returns true if the o1 can be used in this comparator.

Parameters:

o1 - a sequence element

Returns:

true if its usable for this comparator
