Examples of org.apache.cayenne.map.Relationship

org.apache.cayenne.map.Relationship
Defines a relationship between two entities. In a DataMap graph relationships represent "arcs" connecting entity "nodes". Relationships are directional, i.e. they have a notion of source and target entity. This makes DataMap a "digraph".
