Examples of org.apache.derby.iapi.store.access.TransactionController.openSort()

org.apache.derby.iapi.store.access.TransactionController.openSort()
Open a sort controller for a sort previously created in this transaction. Sort controllers are used to insert rows into the sort.
There may (in the future) be multiple sort inserters for a given sort, the idea being that the various threads of a parallel query plan can all insert into the sort. For now, however, only a single sort controller per sort is supported. @param id The identifier of the sort to open, as returned fromcreateSort. @return A sort controller to use for inserting. @exception StandardException From a lower-level exception.
