Partitioning is used to switch between different instances of multi-services like it is used e.g. in the event buffer tampering.
Example code: =============
Switch between buffers for data processing. Use this technique to populate e.g. different datastores in order to later compare the different results.
SmartIF<IPartitionControl> partCtrl(eventSvc()); if ( partCtrl.isValid() ) { if ( partCtrl.activate("Partition_1").isSuccess() ) { SmartDataPtr mcparts(eventSvc(), "MC/Particles"); .... work with particles from buffer "Partition 1" all data registered by code here will go to "Partition 2" } if ( partCtrl.activate("Partition_2").isSuccess() ) { SmartDataPtr mcparts(eventSvc(), "MC/Particles"); .... work with particles from buffer "Partition 2" they are NOT they same as those in buffer 1 all data registered by code here will go to "Partition 2" } }
The access to the underlying service is also possible.
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Be careful: This usage MAY NOT MODIFY e.g. the datastore by adding additional objects! This should solely by used for analysis after buffer tampering. In particular with "data on demand" this can easily have unexpected results.
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
SmartIF<IPartitionControl> partCtrl(eventSvc()); if ( partCtrl ) { IInterface* ptr = 0; if ( partCtrl->get("Partition 1", ptr).isSuccess() ) { SmartIF<IDataProviderSvc> partition(ptr); // Now we can work directly with this partition // There is no additional dispathing in the "eventSvc()". SmartDataPtr mcparts(partition, "MC/Particles"); if ( mcparts ) { } } }

00073 { return IID_IPartitionControl; }
| virtual StatusCode IPartitionControl::create | ( | const std::string & | name, | |
| const std::string & | type | |||
| ) | [pure virtual] |
Create a new partition.
If the partition exists already the existing object is returned. In this event the return code is PARTITION_EXISTS. The partition type typically contains all the information necessary to access the corresponding service, typically a pair "<service-type>/<service name>"
| name | [IN] Partition name | |
| type | [IN] Partition type |
| virtual StatusCode IPartitionControl::create | ( | const std::string & | name, | |
| const std::string & | type, | |||
| IInterface *& | pPartition | |||
| ) | [pure virtual] |
Create a new partition.
If the partition exists already the existing object is returned. In this event the return code is PARTITION_EXISTS. The partition type typically contains all the information necessary to access the corresponding service, typically a pair "<service-type>/<service name>"
| name | [IN] Partition name | |
| type | [IN] Partition type | |
| pPartition | [OUT] Reference to the created/existing partition |
| virtual StatusCode IPartitionControl::drop | ( | const std::string & | name | ) | [pure virtual] |
Remove a partition object.
If the partition object does not exists, the return code is PARTITION_NOT_PRESENT. The partition may not be used anymore after this call.
| name | [IN] Partition name |
| virtual StatusCode IPartitionControl::drop | ( | IInterface * | pPartition | ) | [pure virtual] |
Remove a partition object.
If the partition object does not exists, the return code is PARTITION_NOT_PRESENT. The partition may not be used anymore after this call. If the interface pointer is invalid, IInterface::NO_INTERFACE is returned.
| pPartition | [IN] Reference to existing partition |
| virtual StatusCode IPartitionControl::activate | ( | const std::string & | name | ) | [pure virtual] |
Access an existing partition object.
Preferred call. The activation of a partition does not change the state of the partition. It only means that any call issued to the corresponding multi-service will be redirected to the this partition - typically a service implementing the same interfaces as the multi-service.
| name | [IN] Partition name |
| virtual StatusCode IPartitionControl::activate | ( | IInterface * | pPartition | ) | [pure virtual] |
Access an existing partition object.
The activation of a partition does not change the state of the partition. It only means that any call issued to the corresponding multi-service will be redirected to the this partition - typically a service implementing the same interfaces as the multi-service.
If the interface pointer is invalid, IInterface::NO_INTERFACE is returned.
| pPartition | [IN] Pointer to the partition. |
| virtual StatusCode IPartitionControl::get | ( | const std::string & | name, | |
| IInterface *& | pPartition | |||
| ) | const [pure virtual] |
Access an existing partition object.
| name | [IN] Partition name | |
| pPartition | [IN] Location to store the pointer to the partition. |
| virtual StatusCode IPartitionControl::activePartition | ( | std::string & | name, | |
| IInterface *& | pPartition | |||
| ) | const [pure virtual] |
Access the active partition object.
| name | [OUT] Partition name | |
| pPartition | [OUT] Location to store the pointer to the partition. |
| virtual StatusCode IInterface::queryInterface | ( | const InterfaceID & | riid, | |
| void ** | ppvInterface | |||
| ) | [pure virtual, inherited] |
Query interfaces of Interface.
| riid | ID of Interface to be retrieved | |
| ppvInterface | Pointer to Location for interface pointer |
Implemented in Algorithm, AlgTool, Auditor, ConversionSvc, Converter, DataSvc, EventSelectorDataStream, MinimalEventLoopMgr, PropertyMgr, SelectStatement, and Service.
| virtual unsigned long IInterface::addRef | ( | ) | [pure virtual, inherited] |
Increment the reference count of Interface instance.
Implemented in Algorithm, AlgTool, Auditor, Converter, EventSelectorDataStream, IFactory, PropertyMgr, SelectStatement, and Service.
| virtual unsigned long IInterface::release | ( | ) | [pure virtual, inherited] |
Release Interface instance.
