- All Known Implementing Classes:
ExtractedDatabaseMetaDataImpl
public interface ExtractedDatabaseMetaData
Information extracted fromDatabaseMetaData
regarding what the JDBC driver reports as being supported or not. ObviouslyDatabaseMetaData
reports many things, these are a few in which we have particular interest.
