NamedAssociationWrapper (Apache Zest™ (Java Edition) SDK 2.1)

java.lang.Object
- org.qi4j.api.association.NamedAssociationWrapper

All Implemented Interfaces:

Iterable<String>, AbstractAssociation, NamedAssociation<Object>
```
public class NamedAssociationWrapper
extends Object
implements NamedAssociation<Object>
```
If you want to catch calls to NamedAssociations, then create a GenericConcern that wraps the Zest-supplied NamedAssociations instance with NamedAssociationsWrapper. Override methods to perform your custom code.
