Class ScopeDependencySelector

java.lang.Object
  org.sonatype.aether.util.graph.selector.ScopeDependencySelector

All Implemented Interfaces:

DependencySelector

public class ScopeDependencySelector
extends java.lang.Object
implements DependencySelector

A dependency selector that filters transitive dependencies based on their scope. Direct dependencies are always included regardless of their scope. Note: This filter does not assume any relationships between the scopes. In particular, the filter is not aware of scopes that logically include other scopes.

Parameters:

excluded - The set of scopes to exclude, may be null or empty to exclude no scope.

Method Detail

selectDependency

public boolean selectDependency(Dependency dependency)

Description copied from interface: DependencySelector

Applies exclusions to the specified dependency.

Specified by:

selectDependency in interface DependencySelector

Parameters:

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

Returns:

false if the dependency should be excluded from the children of the current node, true otherwise.

deriveChildSelector

public DependencySelector deriveChildSelector(DependencyCollectionContext context)

Description copied from interface: DependencySelector

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

Specified by:

deriveChildSelector in interface DependencySelector

Parameters:

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

Returns:

The dependency filter for the target node, must not be null.
