org.apache.derby.impl.store.access.BackingStoreHashTableFromScan
| BackingStoreHashTableFromScan | | class BackingStoreHashTableFromScan extends BackingStoreHashtable (Code) | | Extend BackingStoreHashtable with the ability to maintain the underlying
openScan() until the hashtable has been closed. This is necessary for
long row access. Access to long row delays actual objectification until
the columns are accessed, but depends on the underlying table to be still
open when the column is accessed.
Transactions are obtained from an AccessFactory.
