org.gcube.informationsystem.resourceregistry.queries.json.base.standalone.JsonQueryEntitySchema

public class JsonQueryEntitySchema
extends JsonQueryElement

Translates a JSON query subtree representing an entity Type definition (ResourceSchema or FacetSchema).

Entity Type definitions are flat, standalone vertex records with no graph relations to traverse relative to each other: always the entry point of the query, hence extending JsonQueryElement directly rather than JsonQueryERElement.
