Class ConflictMarker

java.lang.Object

org.eclipse.aether.util.graph.transformer.ConflictMarker

All Implemented Interfaces:

DependencyGraphTransformer

public final class ConflictMarker
extends java.lang.Object
implements DependencyGraphTransformer

A dependency graph transformer that identifies conflicting dependencies. When this transformer has executed, the transformation context holds a Map<DependencyNode, Object> where dependency nodes that belong to the same conflict group will have an equal conflict identifier. This map is stored using the key TransformationContextKeys.CONFLICT_IDS.

Method Detail

transformGraph

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

After the execution of this method, every DependencyNode with an attached dependency is member of one conflict group.

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.
