void addPostCommitWork(Serviceable work)
Add to the list of post commit work that may be processed after this transaction commits. If this transaction aborts, then the post commit work list will be thrown away. No post commit work will be taken out on a rollback to save point.
This routine simply delegates the work to the Rawstore transaction.

.void closeMe(ScanManager scan)
Take whatever cleanup action is appropriate to a closed scan. It is likely this routine will remove references to the scan object that it was maintaining for cleanup purposes.
void closeMe(ConglomerateController conglom_control)
Take whatever cleanup action is appropriate to a closed conglomerateController. It is likely this routine will remove references to the ConglomerateController object that it was maintaining for cleanup purposes.
void closeMe(SortController sort_control)
Take whatever cleanup action is appropriate to a closed sortController. It is likely this routine will remove references to the SortController object that it was maintaining for cleanup purposes.
TransactionManager getInternalTransaction() throws StandardException
Start an internal transaction. An internal transaction is a completely separate transaction from the current user transaction. All work done in the internal transaction must be physical (ie. it can be undone physically by the rawstore at the page level, rather than logically undone like btree insert/delete operations). The rawstore guarantee's that in the case of a system failure all open Internal transactions are first undone in reverse order, and then other transactions are undone in reverse order.
Internal transactions are meant to implement operations which, if interupted before completion will cause logical operations like tree searches to fail. This special undo order insures that the state of the tree is restored to a consistent state before any logical undo operation which may need to search the tree is performed.
StandardException
- Standard exception policy.Transaction getRawStoreXact() throws StandardException
Access methods often need direct access to the "Transaction" - ie. the raw store transaction, so give access to it.
StandardException
- Standard exception policy.Conglomerate findExistingConglomerateFromKey(ContainerKey container_key) throws StandardException
Throws exception if it can't find a matching conglomerate for the ContainerKey.
container_key
- container key of target conglomerate.StandardException
