Class ScopeDependencySelector

java.lang.Object

org.eclipse.aether.util.graph.selector.ScopeDependencySelector

All Implemented Interfaces:

DependencySelector

public final 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.

Constructor Detail

ScopeDependencySelector

public ScopeDependencySelector(java.util.Collection<java.lang.String> included,
                               java.util.Collection<java.lang.String> excluded)

Creates a new selector using the specified includes and excludes.

Parameters:

included - The set of scopes to include, may be null or empty to include any scope.

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

ScopeDependencySelector

public ScopeDependencySelector(java.lang.String... excluded)

Creates a new selector using the specified excludes.

Parameters:

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

                                java.util.Collection<java.lang.String> included,

selectDependency

public boolean selectDependency(Dependency dependency)

Description copied from interface: DependencySelector

Decides whether the specified dependency should be included in the dependency graph.

Specified by:

selectDependency in interface DependencySelector

Parameters:

dependency - The dependency to check, 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 selector for the target node or null if dependencies should be unconditionally included in the sub graph.

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object

eq

private static <T> boolean eq(T o1,
                              T o2)

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object
