  org.apache.maven.archiva.dependency.graph.DependencyGraphUtils

public class DependencyGraphUtils
extends java.lang.Object

Utilities for manipulating the DependencyGraph.

Constructor Summary

DependencyGraphUtils()

Method Summary

static void	addNodeFromModel(org.apache.maven.archiva.model.ArchivaProjectModel model, DependencyGraph graph, DependencyGraphNode fromNode) Standard way to add a model to the graph.
static void	cleanupOrphanedNodes(DependencyGraph graph) Clean out any nodes that may have become orphaned in the graph.
static DependencyGraphEdge	clone(DependencyGraphEdge edge) Create a clone of an edge.
static void	collapseNodes(DependencyGraph graph, DependencyGraphNode nodeFROM, DependencyGraphNode nodeTO) Functionaly similar to #collapseVersions(DependencyGraph, ArtifactReference, String, String), but in a new, easier to use, format.

Method Detail

addNodeFromModel

public static void addNodeFromModel(org.apache.maven.archiva.model.ArchivaProjectModel model,
                                    DependencyGraph graph,
                                    DependencyGraphNode fromNode)

Standard way to add a model to the graph. NOTE: Used by archiva-repository-layer runtime and archiva-dependency-graph tests.

Parameters:

model - the model to add

graph - the graph to add it to

fromNode - the node to add it from.

cleanupOrphanedNodes

public static void cleanupOrphanedNodes(DependencyGraph graph)

Clean out any nodes that may have become orphaned in the graph.

Parameters:

graph - the graph to check.

collapseNodes

public static void collapseNodes(DependencyGraph graph,
                                 DependencyGraphNode nodeFROM,
                                 DependencyGraphNode nodeTO)

Functionaly similar to #collapseVersions(DependencyGraph, ArtifactReference, String, String), but in a new, easier to use, format. 1) Removes the FROM edges connected to the FROM node 2) Moves the TO edges connected to the FROM node to the TO node. 3) Removes the FROM node (which is now orphaned)

Parameters:

graph - the graph to perform operation on

nodeFrom - the node to collapse from

nodeTo - the node to collapse to

clone

public static DependencyGraphEdge clone(DependencyGraphEdge edge)

Create a clone of an edge.

Parameters:

edge - the edge to clone.

Returns:

the cloned edge.
