- Method Detail
  - apply
```
public void apply(Traversal.Admin<?,?> traversal)
```
    Specified by:
    
    apply in interface TraversalStrategy<TraversalStrategy.OptimizationStrategy>
  - endsWithElement
```
public static final boolean endsWithElement(Step<?,?> currentStep)
```
  - applyPrior
```
public Set<Class<? extends TraversalStrategy.OptimizationStrategy>> applyPrior()
```
    Description copied from interface: TraversalStrategy
    
    The set of strategies that must be executed before this strategy is executed. If there are no ordering requirements, the default implementation returns an empty set.
    
    Specified by:
    
    applyPrior in interface TraversalStrategy<TraversalStrategy.OptimizationStrategy>
    
    Returns:
    
    the set of strategies that must be executed prior to this one.
  - instance
```
public static MessagePassingReductionStrategy instance()
```
