Method Details

persistCollection

public <T> Collection<T> persistCollection(Collection<T> beans,
 Class... lazyRelations)

this extension tries to persist new data from source db to this replication db. the method #addReplicationEntities(de.tsl2.nano.service.util.IGenericBaseService, java.util.List, java.util.List) inserts all unpersisted relations - but in an undefined order. so we have to try to persist the collection for several times. if no element was persisted in one loop, the trial and error job stops.

Specified by:

persistCollection in interface IGenericBaseService

Overrides:

persistCollection in class GenericLocalServiceBean

persistRep

protected <T> T persistRep(T bean)

persistRep

Parameters:

bean -

Returns:

persistNoTransaction

public <T> T persistNoTransaction(T bean,
 boolean refreshBean,
 boolean flush,
 Class... lazyRelations)

Specified by:

persistNoTransaction in interface IGenericBaseService

Overrides:

persistNoTransaction in class GenericReplicatingServiceBean
