Class to store and execute Packet ACL transactions. Such a transaction is a sequence of Packet ACL commands that should executed atomically.
This is also used as the container class for all access to the ACLs maintained by the FEA.
A map of pending transactions is maintained to facilitate rollback.
| typedef TransactionManager::Operation Operation | Operation |
| enum { MAX_TRANS_PENDING = 16, MAX_OPS_PENDING = 200, TIMEOUT_MS = 10000 } |
| PaTransactionManager (EventLoop& e, PaTableManager& ptm,
uint32_t max_pending = MAX_TRANS_PENDING)
| PaTransactionManager |
| const string& error ()
| error |
[const]
Returns: string representing first error during commit. If string is empty(), then no error occurred.
| inline size_t retrieve_max_ops ()
| retrieve_max_ops |
[const]
Returns: maximum number of pending operations in a transaction allowed by this class.
| inline PaTableManager& ptm ()
| ptm |
[const]
Returns: the PaTableManager associated with this PaTransactionManager.
| inline PaBackend* get_backend ()
| get_backend |
[const]
Returns: pointer to the current PaBackend in use.
| bool set_backend (const char* name)
| set_backend |
Returns: true if the named PaBackend was successfully constructed. The currently active PaBackend, if any, will be freed, only if construction was successful.
