Package org.eclipse.aether.util.graph.manager

Class DefaultDependencyManager

java.lang.Object

org.eclipse.aether.util.graph.manager.DefaultDependencyManager

All Implemented Interfaces:

DependencyManager

public final class DefaultDependencyManager
extends java.lang.Object
implements DependencyManager

A dependency manager managing dependencies on all levels supporting transitive dependency management.

Note:Unlike the ClassicDependencyManager and the TransitiveDependencyManager this implementation applies management also on the first level. This is considered the resolver's default behaviour. It ignores all management overrides supported by the MavenModelBuilder.

Since:

1.4.0

Method Detail

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.

getKey

private java.lang.Object getKey(Artifact a)

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object
