CatalogRowFactory
public CatalogRowFactory(org.apache.derby.iapi.services.uuid.UUIDFactory uuidf, org.apache.derby.iapi.sql.execute.ExecutionFactory ef, org.apache.derby.iapi.types.DataValueFactory dvf, boolean convertIdToLower)
| Method Detail |
getExecutionFactory
public org.apache.derby.iapi.sql.execute.ExecutionFactory getExecutionFactory()
- Gets a ExecutionFactory
getUUIDFactory
public org.apache.derby.iapi.services.uuid.UUIDFactory getUUIDFactory()
- Get the UUID factory
getCanonicalTableUUID
public org.apache.derby.catalog.UUID getCanonicalTableUUID()
- Get the UUID of this catalog. This is the hard-coded uuid for
this catalog that is generated for releases starting with Plato (1.3).
Earlier releases generated their own UUIDs for system objectss on
the fly.
getCanonicalHeapUUID
public org.apache.derby.catalog.UUID getCanonicalHeapUUID()
- Get the UUID of the heap underlying this catalog. See getCanonicalTableUUID()
for a description of canonical uuids.
getCanonicalIndexUUID
