  • Field Details

    • CONCRETE_STEPS

      static final List<Class<? extends Step>> CONCRETE_STEPS
      Concrete implementations of this contract that can be referenced as TinkerPop implementations.

  • Method Details

    • getMergeTraversal

      Traversal.Admin<S,Map> getMergeTraversal()

    • getMergeMapWithGValue

      default Object getMergeMapWithGValue()
      Gets the merge map from this step. If the map was originally passed as a GValue<Map>, that is returned directly. If it was originally passed as a Map or ConstantTraversal<Map>, then a Map is returned. Otherwise, the MergeMap is returned in Traversal form.

    • getOnCreateTraversal

      Traversal.Admin<S,Map> getOnCreateTraversal()

    • getOnCreateMapWithGValue

      default Object getOnCreateMapWithGValue()
      Gets the onCreate map from this step. If the map was originally passed as a GValue<Map>, that is returned directly. If it was originally passed as a Map or ConstantTraversal<Map>, then a Map is returned. Otherwise, the onCreate is returned in Traversal form.

    • getOnMatchTraversal

      Traversal.Admin<S,Map<String,?>> getOnMatchTraversal()

    • getOnMatchMapWithGValue

      default Object getOnMatchMapWithGValue()
      Gets the onMatch map from this step. If the map was originally passed as a GValue<Map>, that is returned directly. If it was originally passed as a Map or ConstantTraversal<Map>, then a Map is returned. Otherwise, the onMatch is returned in Traversal form.

    • setMerge

      void setMerge(Traversal.Admin<?,Map<Object,Object>> mergeMap)

    • setOnCreate
