Interface DependencyTraverser

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
    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 Details

    • 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.
