- - ### Field Detail

    - #### INSTANCE

          public static final DependencyGraphTransformer INSTANCE

      A ready-made instance of this dependency graph transformer which can safely be reused throughout an entire application regardless of multi-threading.

  - ### Constructor Detail

    - #### NoopDependencyGraphTransformer

          public NoopDependencyGraphTransformer()

      Creates a new instance of this graph transformer. Usually, `INSTANCE` should be used instead.

  - ### Method Detail

    - #### transformGraph

          public DependencyNode transformGraph(DependencyNode node,
                                      DependencyGraphTransformationContext context)
                                        throws RepositoryException

      Description copied from interface: `DependencyGraphTransformer`
      Transforms the dependency graph denoted by the specified root node. The transformer may directly change the provided input graph or create a new graph, the former is recommended for performance reasons.
      Specified by:
        `transformGraph` in interface `DependencyGraphTransformer`
      Parameters:
        `node` - The root node of the (possibly cyclic!) graph to transform, must not be `null`.
        `context` - The graph transformation context, must not be `null`.
      Returns:
        The result graph of the transformation, never `null`.
      Throws:
        `RepositoryException` - If the transformation failed.
