Concept (Grakn 0.10.0 API)

All Superinterfaces:

Comparable<Concept>

All Known Subinterfaces:

Entity, EntityType, Instance, Relation, RelationType, Resource<D>, ResourceType<D>, RoleType, Rule, RuleType, Type
```
public interface Concept
extends Comparable<Concept>
```
A Concept represents anything in the graph. It provides methods to retrieve information about the Concept, and determine if it is a Type (Entity Type, Role Type, Relation Type, Rule Type or Resource Type) or Instance (Entity, Relation, Resource, Rule).
