Class BulkOperationCleanupAction

java.lang.Object

org.hibernate.action.BulkOperationCleanupAction

All Implemented Interfaces:

java.io.Serializable, Executable

public class BulkOperationCleanupAction
extends java.lang.Object
implements Executable, java.io.Serializable

An ActionQueue Executable for ensuring shared cache cleanup in relation to performed bulk HQL queries.

NOTE: currently this executes for INSERT queries as well as UPDATE and DELETE queries. For INSERT it is really not needed as we'd have no invalid entity/collection data to cleanup (we'd still nee to invalidate the appropriate update-timestamps regions) as a result of this query.

Constructor Detail

BulkOperationCleanupAction

public BulkOperationCleanupAction(SessionImplementor session,
                          Queryable[] affectedQueryables)

Constructs an action to cleanup "affected cache regions" based on the affected entity persisters. The affected regions are defined as the region (if any) of the entity persisters themselves, plus the collection regions for any collection in which those entity persisters participate as elements/keys/etc.

Parameters:

session - The session to which this request is tied.

affectedQueryables - The affected entity persisters.

BulkOperationCleanupAction

public BulkOperationCleanupAction(SessionImplementor session,
                          java.util.Set tableSpaces)

Constructs an action to cleanup "affected cache regions" based on a set of affected table spaces. This differs from BulkOperationCleanupAction(SessionImplementor, Queryable[]) in that here we have the affected table names. From those we deduce the entity persisters which are affected based on the defined table spaces; and from there, we determine the affected collection regions based on any collections in which those entity persisters participate as elements/keys/etc.

Parameters:

session - The session to which this request is tied.

tableSpaces - The table spaces.

Method Detail

getPropertySpaces

public java.io.Serializable[] getPropertySpaces()

Description copied from interface: Executable

What spaces (tables) are affected by this action?

Specified by:

getPropertySpaces in interface Executable

Returns:

The spaces affected by this action.

getBeforeTransactionCompletionProcess

public BeforeTransactionCompletionProcess getBeforeTransactionCompletionProcess()

Description copied from interface: Executable

Get the before-transaction-completion process, if any, for this action.

Specified by:

getBeforeTransactionCompletionProcess in interface Executable

Returns:

The before-transaction-completion process, or null if we have no before-transaction-completion process

getAfterTransactionCompletionProcess

public AfterTransactionCompletionProcess getAfterTransactionCompletionProcess()

Description copied from interface: Executable

Get the after-transaction-completion process, if any, for this action.

Specified by:

getAfterTransactionCompletionProcess in interface Executable

Returns:

The after-transaction-completion process, or null if we have no after-transaction-completion process

beforeExecutions

public void beforeExecutions()
                      throws HibernateException

Description copied from interface: Executable
