- - ### Constructor Detail

    - #### MinGlobalStep

          public MinGlobalStep(Traversal.Admin traversal)

  - ### Method Detail

    - #### processAllStarts

          public void processAllStarts()

      Description copied from interface: `Barrier`
      Process all left traversers by do not yield the resultant output. This method is useful for steps like `ReducingBarrierStep`, where traversers can be processed "on the fly" and thus, reduce memory consumption.
      Specified by:
        `processAllStarts` in interface `Barrier<S extends Comparable>`
      Overrides:
        `processAllStarts` in class `ReducingBarrierStep<S extends Comparable,S extends Comparable>`

    - #### projectTraverser

          public S projectTraverser(Traverser.Admin<S> traverser)

      Specified by:
        `projectTraverser` in class `ReducingBarrierStep<S extends Comparable,S extends Comparable>`

    - #### getRequirements

          public Set<TraverserRequirement> getRequirements()

      Description copied from interface: `Step`
      Provide the necessary `TraverserRequirement` that must be met by the traverser in order for the step to function properly. The provided default implements returns an empty set.
      Returns:
        the set of requirements
