DependencyGraphTransformer

All Known Implementing Classes:

ChainedDependencyGraphTransformer, ConflictIdSorter, ConflictMarker, ConflictResolver, JavaDependencyContextRefiner, NoopDependencyGraphTransformer
```
public interface DependencyGraphTransformer
```
Transforms a given dependency graph.
Note: Implementations must be stateless.
Warning: Dependency graphs may generally contain cycles. As such a graph transformer that cannot assume for sure that cycles have already been eliminated must gracefully handle cyclic graphs, e.g. guard against infinite recursion.

`DependencyNode`	`transformGraph(DependencyNode node, DependencyGraphTransformationContext context)`	Transforms the dependency graph denoted by the specified root node.

  - transformGraph
```
DependencyNode transformGraph(DependencyNode node,
                              DependencyGraphTransformationContext context)
                       throws RepositoryException
```
    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.
    
    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.
