Method Detail

saveChangesCore

protected void saveChangesCore(SaveWorkState saveWorkState)

Persist the changes to the entities in the SaveWorkState that is passed in. This implements the abstract method in SaveProcessor. After the completion of this method the saveWorkState.toSaveResult method may be called the will return a SaveResult instance. This method both persists the entities and creates the collection of KeyMappings, which map the temporary keys to their real generated keys. Note that this method sets session.FlushMode = FlushMode.MANUAL, so manual flushes are required.

Specified by:

saveChangesCore in class SaveProcessor

Parameters:

saveWorkState -

processRelationships

public void processRelationships(EntityInfo entityInfo,
                        boolean removeMode)

Description copied from class: SaveProcessor

Called for each entity to attach of detach it from any related entities.

Specified by:

processEntity

protected void processEntity(EntityInfo entityInfo)

Parameters:

entityInfo -

restoreOldVersionValue

protected void restoreOldVersionValue(EntityInfo entityInfo,
                          org.hibernate.metadata.ClassMetadata classMeta)

Restore the old value of the concurrency column so Hibernate will save the entity. Otherwise it will complain because Breeze has already changed the value.

Parameters:

entityInfo -

classMeta -

refreshFromSession

protected void refreshFromSession(SaveWorkState saveWorkState)

Refresh the entities from the database. This picks up changes due to triggers, etc. and makes Hibernate update the foreign keys.

Parameters:
