Detailed Description

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.
