List<<any>>	getComparators() Get the comparators associated with this holder.

Method Detail

addComparator

void addComparator(Traversal.Admin<S,C> traversal,
                   Comparator<C> comparator)

Add a Traversal-based Comparator to the holder. If no traversal is needed, use IdentityTraversal.

Parameters:

traversal - the traversal to pre-process the object by.

comparator - the comparator to compare the result of the object after traversal processing

getComparators

List<<any>> getComparators()

Get the comparators associated with this holder. The comparators are ordered according to their oder of operation.

Returns:

a list of Traversal/Comparator-pairs
