public interface JanusGraphSchemaType
extends JanusGraphSchemaElement

A JanusGraphSchemaType is a JanusGraphSchemaElement that represents a label or key used in the graph. As such, a schema type is either a RelationType or a VertexLabel.

JanusGraphSchemaTypes are a special JanusGraphSchemaElement in that they are referenced from the main graph when creating vertices, edges, and properties.
