Constructor Detail

UpdateObjectQuery

public UpdateObjectQuery()

PUBLIC: Default constructor.

UpdateObjectQuery

public UpdateObjectQuery(java.lang.Object objectToUpdate)

PUBLIC: Create an update query with the object being updated.

UpdateObjectQuery

public UpdateObjectQuery(Call call)

PUBLIC: Create an update query with the custom call.

Method Detail

executeCommit

public void executeCommit()
                   throws DatabaseException,
                          OptimisticLockException

INTERNAL: Perform an update.

Overrides:

executeCommit in class WriteObjectQuery

Throws:

DatabaseException

OptimisticLockException

executeCommitWithChangeSet

public void executeCommitWithChangeSet()
                                throws DatabaseException,
                                       OptimisticLockException

INTERNAL: Perform an update.

Overrides:

executeCommitWithChangeSet in class WriteObjectQuery

prepare

protected void prepare()

INTERNAL: Prepare the receiver for execution in a session.

Overrides:

prepare in class ObjectLevelModifyQuery

checkForCustomQuery

protected DatabaseQuery checkForCustomQuery(org.eclipse.persistence.internal.sessions.AbstractSession session,
                                            org.eclipse.persistence.internal.sessions.AbstractRecord translationRow)

INTERNAL: Check to see if a custom query should be used for this query. This is done before the query is copied and prepared/executed. null means there is none.

isUpdateObjectQuery

public boolean isUpdateObjectQuery()

PUBLIC: Return if this is an update object query.

Overrides:

isUpdateObjectQuery in class DatabaseQuery
