  protected boolean usesOptimisticLocking

  Indicates whether the query should use optimistic locking.

Constructor Detail

• DeleteObjectQuery

  public DeleteObjectQuery()

• DeleteObjectQuery

  public DeleteObjectQuery(java.lang.Object objectToDelete)

• DeleteObjectQuery

  public DeleteObjectQuery(Call call)

Method Detail

• isFullRowRequired

  public boolean isFullRowRequired()

  ADVANCED: Return if the full row is required by the delete query. This can be set on custom delete queries if more than the objects primary key and version is required.

• setIsFullRowRequired

• getDefaultRedirector

  protected QueryRedirector getDefaultRedirector()

  INTERNAL: Returns the specific default redirector for this query type. There are numerous default query redirectors. See ClassDescriptor for their types.

  Overrides:

  getDefaultRedirector in class DatabaseQuery

                                        throws DatabaseException,
                                               OptimisticLockException

  Returns:

  object - the object being deleted.

  Throws:

  DatabaseException - - an error has occurred on the database.

  OptimisticLockException - - an error has occurred using the optimistic lock feature.

• isDeleteObjectQuery

  public boolean isDeleteObjectQuery()

  PUBLIC: Return if this is a delete object query.

  Overrides:

  isDeleteObjectQuery in class DatabaseQuery

• setObject

  public void setObject(java.lang.Object object)

  PUBLIC: (REQUIRED) Set the object required for modification.

  Overrides:

  setObject in class ObjectLevelModifyQuery

• shouldUseOptimisticLocking

  protected boolean shouldUseOptimisticLocking(java.lang.Object object)

  INTERNAL: Determines whether the query should use optimistic locking with the passed object.

• usesOptimisticLocking

  public boolean usesOptimisticLocking()

  INTERNAL: Indicating whether the query should use optimistic locking.

• prepare

  protected void prepare()

  INTERNAL: Prepare the receiver for execution in a session.

  Overrides:

  prepare in class ObjectLevelModifyQuery

• prepareCustomQuery

  protected void prepareCustomQuery(DatabaseQuery customQuery)

  INTERNAL: Set the properties needed to be cascaded into the custom query. A custom query is set by the user, or used by default to allow caching of the prepared query. In a unit of work the custom query is used directly, so this step is bypassed.

  Overrides:

• prepareForExecution

  public void prepareForExecution()
                           throws QueryException
