DynamicModelDataStore

public DynamicModelDataStore()

Method Details

save

public Set<?> save(SaveContext context)

Description copied from interface: DataStore

Saves a collection of entity instances.

Specified by:

save in interface DataStore

Overrides:

save in class AbstractDataStore

Returns:

set of saved instances

loadOne

protected @Nullable Object loadOne(LoadContext<?> context)

Specified by:

loadOne in class AbstractDataStore

loadAll

protected List<Object> loadAll(LoadContext<?> context)

Specified by:

loadAll in class AbstractDataStore

countAll

protected long countAll(LoadContext<?> context)

Specified by:

countAll in class AbstractDataStore

saveAll

protected Set<Object> saveAll(SaveContext context)

Specified by:

saveAll in class AbstractDataStore

deleteAll

protected Set<Object> deleteAll(SaveContext context)

Specified by:

deleteAll in class AbstractDataStore

collectChanges

protected AttributeChanges collectChanges(Object entity,
 EntityChangedEvent.Type type)

The dynamic entity entry does not track which attributes changed, so an update reports every stored attribute as changed and old values are not available. A deletion reports the last values, so that listeners can see references of the removed instance.

publishEntityChangedEvent

protected void publishEntityChangedEvent(Object entity,
 EntityChangedEvent.Type type,
 AttributeChanges changes)

loadAllValues

protected List<Object> loadAllValues(ValueLoadContext context)

Specified by:

loadAllValues in class AbstractDataStore

countAllValues

protected long countAllValues(ValueLoadContext context)

Specified by:

countAllValues in class AbstractDataStore

beginLoadTransaction

protected Object beginLoadTransaction(boolean joinTransaction)

Specified by:

beginLoadTransaction in class AbstractDataStore

beginSaveTransaction

protected Object beginSaveTransaction(boolean joinTransaction)

Specified by:

beginSaveTransaction in class AbstractDataStore

commitTransaction

protected void commitTransaction(Object transaction)

Specified by:

commitTransaction in class AbstractDataStore

rollbackTransaction

protected void rollbackTransaction(Object transaction)

Specified by:

rollbackTransaction in class AbstractDataStore

getTransactionContextState

protected AbstractDataStore.TransactionContextState getTransactionContextState(boolean isJoinTransaction)

Description copied from class: AbstractDataStore

Invoked after AbstractDataStore.beginLoadTransaction(boolean).
Override this method to create AbstractDataStore.TransactionContextState implementation and store required data in it.

Specified by:

getTransactionContextState in class AbstractDataStore

getName

public String getName()

Description copied from interface: DataStore

This data store instance name with which it is registered in Stores.

setName

public void setName(String name)

Description copied from interface: DataStore

Sets this data store instance name with which it is registered in Stores.
