Constructor Detail

GenericMapperDao

public GenericMapperDao(GenericRowMapper mapper,
                        Class<? extends PersistentEntity> clazz,
                        String table)

Method Detail

load

Returns:

array of ALL instances in persistence layer.

delete

public void delete(T t)

update

public void update(T t)

findIDsWhereCreationDateBetween

public String[] findIDsWhereCreationDateBetween(TimeStamp startTs,
