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.
