All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`addComparator(Traversal.Admin<S,C> traversal, Comparator<C> comparator)`	Add a `Traversal`-based `Comparator` to the holder.
`List<org.javatuples.Pair<Traversal.Admin<S,C>,Comparator<C>>>`	`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<org.javatuples.Pair<Traversal.Admin<S,C>,Comparator<C>>> 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
