Method Detail

apply

public abstract void apply(PersistentFileTransaction transaction)

Apply this update to the given transaction.

Specified by:

apply in interface DatabaseAction<PersistentFileTransaction>

Parameters:

transaction - open transaction

getDatabaseActions

public final List<SpringPersistentObjectSchemaUpdate<T>> getDatabaseActions()

Description copied from interface: SchemaUpdate

Get the action(s) that comprise this update. Ideally, individual actions should be atomic database operations, i.e., each one should either finish completely, or else leave the database in a state where it can be tried again. In any case, each action will be applied within its own transaction when transactions are supported by the database unless SchemaUpdate.isSingleAction() returns true.

Specified by:

getDatabaseActions in interface SchemaUpdate<PersistentFileTransaction>

Returns:

a list of zero or more actions to apply
