List of openSortScan() Examples

Examples of openSortScan()

org.apache.derby.iapi.store.access.TransactionController.openSortScan()
Open a scan for retrieving rows from a sort. Returns a scan controller for retrieving rows from the sort (NOTE: the only legal methods to use on the returned sort controller are next() and fetch() - probably there should be scan controllers and updatable scan controllers).
In the future, multiple sort scans on the same sort will be supported (for parallel execution across a uniqueness sort in which the order of the resulting rows is not important). Currently, only a single sort scan is allowed per sort.
In the future, it will be possible to open a sort scan and start retrieving rows before the last row is inserted. The sort controller would block till rows were available to return. Currently, an attempt to retrieve a row before the sort controller is closed will cause an exception. @param id The identifier of the sort to scan, as returned from createSort. @param hold If true, this scan will be maintained open over commits. @return The sort controller. @exception StandardException From a lower-level exception.
org.apache.derby.iapi.store.access.conglomerate.Sort.openSortScan()
Open a scan controller.
The sort may have been dropped already, in which case this method should thrown an exception. @exception StandardException Standard exception policy.
