    - #### addStrategies

          public TraversalStrategies addStrategies(TraversalStrategy<?>... strategies)

      Description copied from interface: `TraversalStrategies`
      Add all the provided `TraversalStrategy` instances to the current collection. When all the provided strategies have been added, the collection is resorted.
      Specified by:
        `addStrategies` in interface `TraversalStrategies`
      Parameters:
        `strategies` - the traversal strategies to add
      Returns:
        the newly updated/sorted traversal strategies collection

    - #### removeStrategies

          public TraversalStrategies removeStrategies(Class<? extends TraversalStrategy>... strategyClasses)

      Description copied from interface: `TraversalStrategies`
      Remove all the provided `TraversalStrategy` classes from the current collection. When all the provided strategies have been removed, the collection is resorted.
      Specified by:
        `removeStrategies` in interface `TraversalStrategies`
      Parameters:
        `strategyClasses` - the traversal strategies to remove by their class
      Returns:
        the newly updated/sorted traversal strategies collection

    - #### toList

          public List<TraversalStrategy<?>> toList()

      Description copied from interface: `TraversalStrategies`
      Return all the `TraversalStrategy` singleton instances associated with this `TraversalStrategies`.
      Specified by:
        `toList` in interface `TraversalStrategies`

    - #### getStrategy

          public <T extends TraversalStrategy> Optional<T> getStrategy(Class<T> traversalStrategyClass)

      Description copied from interface: `TraversalStrategies`
      Return the `TraversalStrategy` instance associated with the provided class.
      Specified by:
        `getStrategy` in interface `TraversalStrategies`
      Type Parameters:
        `T` - the strategy class type
      Parameters:
        `traversalStrategyClass` - the class of the strategy to get
      Returns:
        an optional containing the strategy instance or not

    - #### applyStrategies

          public void applyStrategies(Traversal.Admin<?,?> traversal)

      Description copied from interface: `TraversalStrategies`
      Apply all the `TraversalStrategy` optimizers to the `Traversal` for the stated `TraversalEngine`. This method must ensure that the strategies are sorted prior to application.
      Specified by:
        `applyStrategies` in interface `TraversalStrategies`
      Parameters:
        `traversal` - the traversal to apply the strategies to

    - #### clone
