ai.grakn.kb.internal.concept

Class SchemaConceptImpl<T extends SchemaConcept>

java.lang.Object

ai.grakn.kb.internal.concept.ConceptImpl

ai.grakn.kb.internal.concept.SchemaConceptImpl<T>

Type Parameters:

T - The leaf interface of the object concept. For example an EntityType or RelationshipType or Role

All Implemented Interfaces:

Concept, SchemaConcept, ContainsTxCache, ConceptVertex, Comparable<Concept>

Direct Known Subclasses:

RoleImpl, RuleImpl, TypeImpl

public abstract class SchemaConceptImpl<T extends SchemaConcept>
extends ConceptImpl
implements SchemaConcept

Schema Specific Concept

Allows you to create schema or ontological elements. These differ from normal graph constructs in two ways: 1. They have a unique Label which identifies them 2. You can link them together into a hierarchical structure
