Class RestorePluginStateStoreTransactionCallbackDecorator

java.lang.Object
  com.atlassian.confluence.importexport.xmlimport.RestorePluginStateStoreTransactionCallbackDecorator

All Implemented Interfaces:

org.springframework.transaction.support.TransactionCallback

public class RestorePluginStateStoreTransactionCallbackDecorator
extends java.lang.Object
implements org.springframework.transaction.support.TransactionCallback

Decorates a TransactionCallback with logic to take a snapshot of the PluginPersistentStateStore before execution and restore it after execution.

The assumption here is that the given callback is performing a site import which leads to BackupImporter.deleteAllDatabaseContent() thus deleting the persisted state of the implementation. The restoration has to be performed before any #doImportInternal upgrades are performed, as any state changes in the plugin system would cause the MemoryPluginPersistentStateStore from the ConfluencePluginManager to be synchronised. Thus an implementation like this is necessary instead of implementing the PostImportTask or reacting on ImportFinishedEvent as they happen after the upgrades have been performed.

5.0
