Class ConflictIdSorter
java.lang.Object
org.sonatype.aether.util.graph.transformer.ConflictIdSorter
- All Implemented Interfaces:
- DependencyGraphTransformer
public class ConflictIdSorter
- extends Object
- implements DependencyGraphTransformer
A dependency graph transformer that creates a topological sorting of the conflict ids which have been assigned to the
dependency nodes. Conflict ids are sorted according to the dependency relation induced by the dependency graph. This
transformer will query the key TransformationContextKeys.CONFLICT_IDS
in the transformation context for an
existing mapping of nodes to their conflicts ids. In absence of this map, the transformer will automatically invoke
the ConflictMarker
to calculate the conflict ids. When this transformer has executed, the transformation
context holds a List<Object>
that denotes the topologically sorted conflict ids. The list will be stored
using the key TransformationContextKeys.SORTED_CONFLICT_IDS
. In addition, the transformer will store a
Boolean
using the key TransformationContextKeys.CYCLIC_CONFLICT_IDS
that indicates whether the
conflict ids have cyclic dependencies.

- 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.
- Specified by:
transformGraph
in interface DependencyGraphTransformer
- Parameters:
node
- The root node of the 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.
