Class EntityAliases

java.lang.Object

java.util.AbstractMap<K,V>

java.util.HashMap<String,String>

org.tentackle.model.EntityAliases

All Implemented Interfaces:

Serializable, Cloneable, Map<String,String>

public class EntityAliases
extends HashMap<String,String>

Holds aliases for entities.
Allows mapping of names used in relations or inheritance to map to entity names, for example, to simplify refactoring.

Example:

    <entityAliases>
       Port = LogisticNode,
       ManifestVoyage = Voyage
    </entityAliases>
 

The alias goes to the left of the equal sign. It will be mapped to the right side.
