Concept (Grakn 0.16.0 API)

All Superinterfaces:

Comparable<Concept>

All Known Subinterfaces:

Entity, EntityType, OntologyConcept, Relation, RelationType, Resource<D>, ResourceType<D>, Role, Rule, RuleType, Thing, Type

All Known Implementing Classes:

RelationReified
```
public interface Concept
extends Comparable<Concept>
```
The base concept implementation.

A concept which can represent anything in the graph which wraps a tinkerpop Vertex. This class forms the basis of assuring the graph follows the Grakn object model. It provides methods to retrieve information about the Concept, and determine if it is a Type (EntityType, Role, RelationType, RuleType or ResourceType) or an Thing (Entity, Relation , Resource, Rule).
