Interface DependencyManager

All Known Implementing Classes:

ClassicDependencyManager, NoopDependencyManager

public interface DependencyManager

Applies dependency management to the dependencies of a dependency node.

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.

context - The dependency collection context, must not be null.

Returns:

The dependency manager for the dependencies of the target node or null if dependency management should no longer be applied.
