DiscriminatingNameMapper

java.lang.Object
- org.eclipse.aether.internal.impl.synccontext.named.DiscriminatingNameMapper

All Implemented Interfaces:

NameMapper
```
@Singleton
@Named("discriminating")
public class DiscriminatingNameMapper
extends java.lang.Object
implements NameMapper
```
Discriminating NameMapper, that wraps another NameMapper and adds a "discriminator" as prefix, that makes lock names unique including the hostname and local repository (by default). The discriminator may be passed in via RepositorySystemSession or is automatically calculated based on the local hostname and repository path. The implementation retains order of collection elements as it got it from NameMapper.nameLocks(RepositorySystemSession, Collection, Collection) method.
The default setup wraps GAVNameMapper, but manually may be created any instance needed.

    Description copied from interface: NameMapper
    
    Creates (opaque) names for passed in artifacts and metadata. Returned collection has max size of sum of the passed in artifacts and metadata collections, or less. If an empty collection is returned, there will be no locking happening. Never returns null. The resulting collection MUST BE "stable" (always sorted by same criteria) to avoid deadlocks by acquiring locks in same order, essentially disregarding the order of the input collections.
