Class ProjectionValueSerializer

java.lang.Object
org.gcube.informationsystem.resourceregistry.persistence.orientdb.queries.ProjectionValueSerializer
public class ProjectionValueSerializer extends Object
Serializes the embedded Property values projected by an _emit query as a read does.

An embedded value is serialized by PropertyElementManagement.getJsonNode(ODocument): an Encrypted value is therefore returned encrypted with the key of the Context of the request. When the caller reads the sensitive metadata identity fields redacted, a projected Metadata value is redacted too. A projected value holding no embedded value is left to the query executor.
