Class OptionalDependencySelector

java.lang.Object

org.eclipse.aether.internal.impl.scope.OptionalDependencySelector

All Implemented Interfaces:

DependencySelector

public final class OptionalDependencySelector
extends Object
implements DependencySelector

A dependency selector that excludes optional dependencies which occur beyond given level.

Important note: equals/hashCode must factor in starting state, as instances of this class (potentially differentially configured) are used now in session, but are kept in a set.

• Dependency.isOptional()

Method Details

fromRoot

public static OptionalDependencySelector fromRoot()

Excludes optional dependencies always (from root).

fromDirect

public static OptionalDependencySelector fromDirect()

Excludes optional transitive dependencies of direct dependencies.

from

public static OptionalDependencySelector from(int applyFrom)

Excludes optional transitive dependencies from given depth (1=root, 2=direct, 3=transitives of direct ones...).

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(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object
