Element (hydra-pg 0.17.6 API)

java.lang.Object
- hydra.neo4j.model.Element

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<Element>

Direct Known Subclasses:

Element.Node, Element.Relationship
```
public abstract class Element
extends java.lang.Object
implements java.io.Serializable, java.lang.Comparable<Element>
```
Either a node or a relationship; the common supertype of the two kinds of graph element. A bare union with no fields of its own: the id and properties live on each variant. Named Element (not Entity, the driver's interface name) to avoid the Neo4j docs' use of "entity" for a node's real-world referent, and to match hydra.pg.model and the root of elementId.
