Method Details

save

public DataContextChangeLog save()

Overrides:

save in class DataContext<HOMEOBJECTCLASS,CONTENTTYPECLASS>

dbDeleteAll

public void dbDeleteAll()

Description copied from class: DataContext

This method is called for completely removing the whole object - with all its sub-object. It MUST be implemented! The data context only manages these beans that are loaded in its content, so a deletion "bean by bean by bean" is not possible (without previously loading all objects...).

Specified by:

dbDeleteAll in class DataContext<HOMEOBJECTCLASS,CONTENTTYPECLASS>

checkIfObjectExistsInDB

public boolean checkIfObjectExistsInDB()

Description copied from class: DataContext

Method to be implemented by extensions: the method must check in the database if the object is available. Dependent on the result the data context will treat the home object as new object or as already existing object.

Specified by:

checkIfObjectExistsInDB in class DataContext<HOMEOBJECTCLASS,CONTENTTYPECLASS>

updateKeys

public void updateKeys()

This method is called as part of the save processing. The implementation can make sure that contained objects share the key of the home object. - In many situations objects are added to the context without a properly filled key. This method can be used to drill down the key of the home object in all the sub-objects which depend on the home object.

updateKeysOfContainedObjects

public void updateKeysOfContainedObjects()

This method is called as part of updateKeys(). DataContext implementations need to override if they provide sub objects. You do not have to override if only the home object is managed in the data context.

getHomeReferenceForDrillDown

public HOMEOBJECTCLASS getHomeReferenceForDrillDown()

updateKeysOfContainedDataContexts

public void updateKeysOfContainedDataContexts()

saveLoadedObjects

protected void saveLoadedObjects()

Description copied from class: DataContext

Actual persisting of objects - which is called during the DataContext.save() method. Extend this method in order to implement some own saving logic for all objects within the DataContext.

Overrides:

saveLoadedObjects in class DataContext<HOMEOBJECTCLASS,CONTENTTYPECLASS>

saveLoadedObjects

protected void saveLoadedObjects(CONTENTTYPECLASS key)

Description copied from class: DataContext

Part of processing in DataContext.saveLoadedObjects(). Each object type is processed, this method executes the saving per object type.

Overrides:

saveLoadedObjects in class DataContext<HOMEOBJECTCLASS,CONTENTTYPECLASS>

executeInTransaction

protected void executeInTransaction(Runnable r)

Specified by:

executeInTransaction in class DataContext<HOMEOBJECTCLASS,CONTENTTYPECLASS>

getHomeObjectContentType

protected CONTENTTYPECLASS getHomeObjectContentType()

Specified by:

getHomeObjectContentType in class DataContext<HOMEOBJECTCLASS,CONTENTTYPECLASS>

postProcessSetObject

protected void postProcessSetObject()

Overrides:

postProcessSetObject in class DataContext<HOMEOBJECTCLASS,CONTENTTYPECLASS>

postProcessAddListObject

protected void postProcessAddListObject()

Overrides:

postProcessAddListObject in class DataContext<HOMEOBJECTCLASS,CONTENTTYPECLASS>

dbDeleteHomeObject

protected void dbDeleteHomeObject()

Specified by:

dbDeleteHomeObject in class DataContext<HOMEOBJECTCLASS,CONTENTTYPECLASS>

dbDeleteAssociatedObjects

protected void dbDeleteAssociatedObjects()

Removes objects that are part of the data context - in addition to the home object. This method is an empty implementation on this level and must be implemented for all data contexts that include more than just the home object.

dbRemoveObject

protected void dbRemoveObject(Object o)

Description copied from class: DataContext

This is the method for actually removing one object that is part of the data context. Override this method following your persistence management.

Specified by:

dbRemoveObject in class DataContext<HOMEOBJECTCLASS,CONTENTTYPECLASS>

dbSaveObject

protected void dbSaveObject(Object o)

Description copied from class: DataContext

This is the method for actually saving one object that is part of the data context. Override this method following your persistence management.

Specified by:

dbSaveObject in class DataContext<HOMEOBJECTCLASS,CONTENTTYPECLASS>

performPhase2SaveInRootDataContext

protected void performPhase2SaveInRootDataContext()
