public abstract static class ConflictResolver.ScopeDeriver extends Object
ConflictResolver that determines the scope of a dependency in relation to the scope
of its parent.
Note: Implementations must be stateless.

ConflictResolver.transformGraph(DependencyNode, DependencyGraphTransformationContext) invocation to
allow implementations to prepare any auxiliary data that is needed for their operation. Given that
implementations must be stateless, a new instance needs to be returned to hold such auxiliary data. The
default implementation simply returns the current instance which is appropriate for implementations which do
not require auxiliary data.root - The root node of the (possibly cyclic!) graph to transform, must not be null.context - The graph transformation context, must not be null.null.org.eclipse.aether.RepositoryException - If the instance could not be retrieved.public abstract void deriveScope(ConflictResolver.ScopeContext context) throws org.eclipse.aether.RepositoryException
ConflictResolver.ScopeContext.setDerivedScope(String) to deliver the result of their calculation. If said method is
not invoked, the conflict resolver will assume the scope of the child dependency remains unchanged.context - The scope context, must not be null.org.eclipse.aether.RepositoryException - If the scope deriviation failed.Copyright © 2010-2015 The Eclipse Foundation. All Rights Reserved.
