Class TempMetadataID

java.lang.Object
  org.teiid.query.metadata.TempMetadataID

All Implemented Interfaces:

Serializable, AbstractMetadataRecord.DataModifiable, AbstractMetadataRecord.Modifiable

public class TempMetadataID
extends Object
implements Serializable, AbstractMetadataRecord.Modifiable, AbstractMetadataRecord.DataModifiable

This class represents a temporary metadata ID. A temporary metadata ID does not exist in a real metadata source. Rather, it is used temporarily in context of processing a single query. This metadata ID can be used to represent either a group or an element depending on the constructor used. TODO: we should be using the real metadata objects, but internal and designer legacy keep us on the temp framework
