Method Detail

save

void save(PreferenceLog entity)
Perform an initial save of a previously unsaved PreferenceLog entity. All subsequent persist actions of this entity should use the #update() method. This operation must be performed within the a database transaction context for the entity's data to be permanently saved to the persistence store, i.e., database. This method uses the EntityManager#persist operation.
 EntityManagerHelper.beginTransaction();
 IPreferenceLogDAO.save(entity);
 EntityManagerHelper.commit();
 

Parameters:
entity - PreferenceLog entity to persist
Throws:
java.lang.RuntimeException - when the operation fails

delete

void delete(PreferenceLog entity)
Delete a persistent PreferenceLog entity. This operation must be performed within the a database transaction context for the entity's data to be permanently deleted from the persistence store, i.e., database. This method uses the EntityManager#delete operation.
 EntityManagerHelper.beginTransaction();
 IPreferenceLogDAO.delete(entity);
 EntityManagerHelper.commit();
 entity = null;
 

Parameters:
entity - PreferenceLog entity to delete
Throws:
java.lang.RuntimeException - when the operation fails

update

PreferenceLog update(PreferenceLog entity)
Persist a previously saved PreferenceLog entity and return it or a copy of it to the sender. A copy of the PreferenceLog entity parameter is returned when the JPA persistence mechanism has not previously been tracking the updated entity. This operation must be performed within the a database transaction context for the entity's data to be permanently saved to the persistence store, i.e., database. This method uses the EntityManager#merge operation.
 EntityManagerHelper.beginTransaction();
 entity = IPreferenceLogDAO.update(entity);
 EntityManagerHelper.commit();
 

Parameters:
entity - PreferenceLog entity to update
Returns:
PreferenceLog the persisted PreferenceLog entity instance, may not be the same
Throws:
java.lang.RuntimeException - if the operation fails

findById

PreferenceLog findById(java.lang.String id)
find the PreferenceLog with id

Parameters:
String - id
Returns:
PreferenceLog

findByProperty

java.util.List<PreferenceLog> findByProperty(java.lang.String propertyName,
                                             java.lang.Object value,
                                             int... rowStartIdxAndCount)
Find all PreferenceLog entities with a specific property value.

Parameters:
propertyName - the name of the PreferenceLog property to query
value - the property value to match
rowStartIdxAndCount - Optional int varargs. rowStartIdxAndCount[0] specifies the the row index in the query result-set to begin collecting the results. rowStartIdxAndCount[1] specifies the the maximum count of results to return.
Returns:
List found by query

findByUserId

java.util.List<PreferenceLog> findByUserId(java.lang.Object userId,
                                           int... rowStartIdxAndCount)
Find all PreferenceLog entities with user id

Parameters:
Object - userId
int... - rowStartIdxAndCount
Returns:
List

findAll

java.util.List<PreferenceLog> findAll(int... rowStartIdxAndCount)
Find all PreferenceLog entities.

Parameters:
int... - rowStartIdxAndCount
Returns:
List
