- Constructor Detail
  - DefaultDependencyNode
```
public DefaultDependencyNode(Dependency dependency)
```
    Creates a new node with the specified dependency.
    
    Parameters:
    
    dependency - The dependency associated with this node, may be null for a root node.
  - DefaultDependencyNode
```
public DefaultDependencyNode(Artifact artifact)
```
    Creates a new root node with the specified artifact as its label. Note that the new node has no dependency, i.e. getDependency() will return null. Put differently, the specified artifact will not be subject to dependency collection/resolution.
    
    Parameters:
    
    artifact - The artifact to use as label for this node, may be null.
  - DefaultDependencyNode
```
public DefaultDependencyNode(DependencyNode node)
```
    Creates a mostly shallow clone of the specified node. The new node has its own copy of any custom data and initially no children.
    
    Parameters:
    
    node - The node to copy, must not be null.
- Method Detail
  - getChildren
```
public List<DependencyNode> getChildren()
```
    Description copied from interface: DependencyNode
    
    Gets the child nodes of this node. To conserve memory, dependency nodes with equal dependencies may share the same child list instance. Hence clients mutating the child list need to be aware that these changes might affect more than this node. Where this is not desired, the child list should be copied before mutation if the client cannot be sure whether it might be shared with other nodes in the graph.
    
    Specified by:
    
    getChildren in interface DependencyNode
    
    Returns:
    
    The child nodes of this node, never null.
  - setChildren
```
public void setChildren(List<DependencyNode> children)
```
    Description copied from interface: DependencyNode
    
    Sets the child nodes of this node.
    
    Specified by:
    
    setChildren in interface DependencyNode
    
    Parameters:
    
    children - The child nodes, may be null
  - getDependency
```
public Dependency getDependency()
```
    Description copied from interface: DependencyNode
    
    Gets the dependency associated with this node. Note: For dependency graphs that have been constructed without a root dependency, this method will yield null when invoked on the graph's root node. The root node of such graphs may however still have a label as returned by DependencyNode.getArtifact().
    
    Specified by:
    
    getDependency in interface DependencyNode
    
    Returns:
    
    The dependency or null if none.
  - getArtifact
```
public Artifact getArtifact()
```
    Description copied from interface: DependencyNode
    
    Gets the artifact associated with this node. If this node is associated with a dependency, this is equivalent to getDependency().getArtifact(). Otherwise the artifact merely provides a label for this node in which case the artifact must not be subjected to dependency collection/resolution.
    
    Specified by:
    
    getArtifact in interface DependencyNode
    
    Returns:
    
    The associated artifact or null if none.
  - setArtifact
```
public void setArtifact(Artifact artifact)
```
    Description copied from interface: DependencyNode
    
    Updates the artifact of the dependency after resolution. The new artifact must have the same coordinates as the original artifact. This method may only be invoked if this node actually has a dependency, i.e. if DependencyNode.getDependency() is not null.
    
    Specified by:
    
    setArtifact in interface DependencyNode
    
    Parameters:
    
    artifact - The artifact satisfying the dependency, must not be null.
  - getRelocations
```
public List<? extends Artifact> getRelocations()
```
    Description copied from interface: DependencyNode
    
    Gets the sequence of relocations that was followed to resolve the artifact referenced by the dependency.
    
    Specified by:
    
    getRelocations in interface DependencyNode
    
    Returns:
    
    The (read-only) sequence of relocations, never null.
  - setRelocations
```
public void setRelocations(List<? extends Artifact> relocations)
```
    Sets the sequence of relocations that was followed to resolve this dependency's artifact.
    
    Parameters:
    
    relocations - The sequence of relocations, may be null.
  - getAliases
```
public Collection<? extends Artifact> getAliases()
```
    Description copied from interface: DependencyNode

    getAliases in interface DependencyNode
    
    Returns:
    
    The (read-only) set of known aliases, never null.

    Parameters:
    
    aliases - The known aliases, may be null.
  - getVersionConstraint
```

```
    Description copied from interface: DependencyNode
    
    Gets the version constraint that was parsed from the dependency's version declaration.
    
    Specified by:
    
    getVersionConstraint in interface DependencyNode
    
    Returns:
    
    The version constraint for this node or null.

    The parsed version or null.
  - setVersion
```
public void setVersion(Version version)

    Specified by:
    
    setOptional in interface DependencyNode
    
    Parameters:
    
    optional - The optional flag, may be null.
