Public Member Functions | |
| AbstractControllerPool (const std::vector< ControllerInfo > &controllerList, int pingDelayInMs, int controllerTimeoutInMs) throw (DriverException, UnexpectedException) | |
| Unique constructor. | |
| virtual | ~AbstractControllerPool () |
| Clears list of controllers. | |
| virtual ControllerInfo | getController ()=0 throw (NoMoreControllerException, UnexpectedException) |
| Gets a controller using the implementation specific policy. | |
| int | numberOfAliveControllers () |
| Gets the number of controllers still known to be alive. | |
| DriverSocket * | newRegisteredSocket (const ControllerInfo &controller) throw (ConnectionException) |
| Registers the given socket to the callback so it can kill this socket when the controller is detected as failed. | |
| void | deleteRegisteredSocket (DriverSocket *socket) |
| Unregisters the given socket from the callback so it can no more be killed or deleted. | |
| void | forceControllerDown (const ControllerInfo &controller) |
| Tell the watcher that a failure has been detected on the given controller. | |
| void | controllerDown (const ControllerInfo &controller) |
| Removes this controller from the list of alive ones. | |
| void | controllerUp (const ControllerInfo &controller) |
| Adds the specified controller to the list of alive ones. | |
| void | setVdbDownOnController (const ControllerInfo &controller) |
| Informs that the given controller's vdb is no more available. | |
| bool | isVdbUpOnController (const ControllerInfo &controller) |
| Tells if the given controller VDB is available. | |
| CriticalSection & | getLock () |
| Gets a reference to the lock object used in this class. | |
| operator std::wstring () | |
| Display useful info in a string. | |
Protected Member Functions | |
| void | addRef () |
| Tells the pool that a new connection is using it. | |
| int | removeRef () |
| Tells the pool that one of its 'user' (ie. | |
| int | getRefCount () |
| Retrieves the number of references left on this instance. | |
| int64_t | getLastTimeZeroRef () |
| Returns the last time the number of references was decreased to zero. | |
Protected Attributes | |
| std::vector< ControllerAndVdbState > | alive_controllers |
| Up-to-date list of controllers that respond to pings. | |
| CriticalSection | pool_CS |
| Mutex on alive controllers. | |

| CarobNS::AbstractControllerPool::AbstractControllerPool | ( | const std::vector< ControllerInfo > & | controllerList, | |
| int | pingDelayInMs, | |||
| int | controllerTimeoutInMs | |||
| ) | throw (DriverException, UnexpectedException) |
Unique constructor.
| controllerList | the controller list on which the policy applies | |
| pingDelayInMs | Interval in milliseconds between two pings of a controller | |
| controllerTimeoutInMs | timeout in milliseconds after which a controller is considered as dead if it did not respond to pings |
| void CarobNS::AbstractControllerPool::controllerDown | ( | const ControllerInfo & | controller | ) |
Removes this controller from the list of alive ones.
Warning: This function should never be called directly, only the callback should make us of this.
| controller | the suspect controller |
| void CarobNS::AbstractControllerPool::controllerUp | ( | const ControllerInfo & | controller | ) |
Adds the specified controller to the list of alive ones.
Warning: This function should never be called directly, only the callback should make us of this.
| controller | the controller that came back |
| void CarobNS::AbstractControllerPool::deleteRegisteredSocket | ( | DriverSocket * | socket | ) |
Unregisters the given socket from the callback so it can no more be killed or deleted.
To be used when socket creation or connection failed
| socket | the socket to unregister |
| void CarobNS::AbstractControllerPool::forceControllerDown | ( | const ControllerInfo & | controller | ) |
Tell the watcher that a failure has been detected on the given controller.
This function should be called when a connection error occurs on the given controller
| controller | the controller suspected of failure |
| virtual ControllerInfo CarobNS::AbstractControllerPool::getController | ( | ) | throw (NoMoreControllerException, UnexpectedException) [pure virtual] |
Gets a controller using the implementation specific policy.
ControllerInfo of the selected controller | NoMoreControllerException | if no controller in the controller list is reachable |
Implemented in CarobNS::RoundRobinControllerPool.
| CriticalSection& CarobNS::AbstractControllerPool::getLock | ( | ) | [inline] |
Gets a reference to the lock object used in this class.
| bool CarobNS::AbstractControllerPool::isVdbUpOnController | ( | const ControllerInfo & | controller | ) |
Tells if the given controller VDB is available.
| controller | the controller to check for vdb state |
| DriverSocket* CarobNS::AbstractControllerPool::newRegisteredSocket | ( | const ControllerInfo & | controller | ) | throw (ConnectionException) |
Registers the given socket to the callback so it can kill this socket when the controller is detected as failed.
| controller | the controller to which the socket is connected |
| int CarobNS::AbstractControllerPool::numberOfAliveControllers | ( | ) |
Gets the number of controllers still known to be alive.
| int CarobNS::AbstractControllerPool::removeRef | ( | ) | [protected] |
Tells the pool that one of its 'user' (ie.
connection) doesn't use it anymore, and return the new number of references
| void CarobNS::AbstractControllerPool::setVdbDownOnController | ( | const ControllerInfo & | controller | ) |
Informs that the given controller's vdb is no more available.
| controller | the controller set vdb to down |
