DependencyTraverser (Maven Artifact Resolver 1.3.2 API)

All Known Implementing Classes:

AndDependencyTraverser, FatArtifactTraverser, StaticDependencyTraverser
```
public interface DependencyTraverser
```
Decides whether the dependencies of a dependency node should be traversed as well.
Note: Implementations must be stateless.
Warning: This hook is called from a hot spot and therefore implementations should pay attention to performance. Among others, implementations should provide a semantic equals() method.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`DependencyTraverser`	`deriveChildTraverser(DependencyCollectionContext context)`	Derives a dependency traverser that will be used to decide whether the transitive dependencies of the dependency given in the collection context shall be traversed.
`boolean`	`traverseDependency(Dependency dependency)`	Decides whether the dependencies of the specified dependency should be traversed.

- Method Detail
  - traverseDependency
```
boolean traverseDependency(Dependency dependency)
```
    Decides whether the dependencies of the specified dependency should be traversed.
    
    Parameters:
    
    dependency - The dependency to check, must not be null.
    
    Returns:
    
    true if the dependency graph builder should recurse into the specified dependency and process its dependencies, false otherwise.
  - deriveChildTraverser
```
DependencyTraverser deriveChildTraverser(DependencyCollectionContext context)
```
    Derives a dependency traverser that will be used to decide whether the transitive dependencies of the dependency given in the collection context shall be traversed. When calculating the child traverser, implementors are strongly advised to simply return the current instance if nothing changed to help save memory.
    
    Parameters:
    
    context - The dependency collection context, must not be null.
    
    Returns:
    
    The dependency traverser for the target node or null if dependencies should be unconditionally traversed in the sub graph.
