Examples of org.teiid.query.metadata.QueryMetadataInterface

org.teiid.query.metadata.QueryMetadataInterface
This interface defines the way that query components access metadata. Any user of a query component will need to implement this interface. Many of these methods take or return things of type "Object". Typically, these objects represent a metadata-implementation-specific metadata ID.
