deriveChildManager

public DependencyManager deriveChildManager(DependencyCollectionContext context)

Description copied from interface: DependencyManager

Derives a dependency manager for the specified collection context. When calculating the child manager, implementors are strongly advised to simply return the current instance if nothing changed to help save memory.

Specified by:

deriveChildManager in interface DependencyManager

Parameters:

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.

manageDependency

public DependencyManagement manageDependency(Dependency dependency)

Description copied from interface: DependencyManager

Applies dependency management to the specified dependency.

Specified by:

manageDependency in interface DependencyManager

Parameters:

dependency - The dependency to manage, must not be null.

Returns:

The management update to apply to the dependency or null if the dependency is not managed at all.

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
