java.lang.Objectcom.j256.ormlite.dao.DaoManager
public class DaoManager
Class which caches created DAOs. Sometimes internal DAOs are used to support such features as auto-refreshing of foreign fields or collections of sub-objects. Since instantiation of the DAO is a bit expensive, this class is used in an attempt to only create a DAO once for each class.
NOTE: To use this cache, you should make sure you've added a DatabaseTable.daoClass()
value to the
annotation to the top of your class.

Method Summary | ||
---|---|---|
static void |
addCachedDatabaseConfigs(Collection<DatabaseTableConfig<?>> configs)
This adds database table configurations to the internal cache which can be used to speed up DAO construction. |
|
static void |
clearCache()
Clear out all of internal caches. |
|
static void |
clearDaoCache()
Clear out our DAO caches. |
|
static
|
createDao(ConnectionSource connectionSource,
Class<T> clazz)
Helper method to create a DAO object without having to define a class. |
|
static
|
createDao(ConnectionSource connectionSource,
DatabaseTableConfig<T> tableConfig)
Helper method to create a DAO object without having to define a class. |
|
static
|
lookupDao(ConnectionSource connectionSource,
Class<T> clazz)
Helper method to lookup a DAO if it has already been associated with the class. |
|
static
|
lookupDao(ConnectionSource connectionSource,
DatabaseTableConfig<T> tableConfig)
Helper method to lookup a DAO if it has already been associated with the table-config. |
|
static void |
registerDao(ConnectionSource connectionSource,
Dao<?,?> dao)
Register the DAO with the cache. |
|
static void |
registerDaoWithTableConfig(ConnectionSource connectionSource,
Dao<?,?> dao)
Same as registerDao(ConnectionSource, Dao) but this allows you to register it just with its
DatabaseTableConfig . |
|
static void |
unregisterDao(ConnectionSource connectionSource,
Dao<?,?> dao)
Remove a DAO from the cache. |

public static <D extends Dao<T,?>,T> D lookupDao(ConnectionSource connectionSource, DatabaseTableConfig<T> tableConfig)
public static void registerDao(ConnectionSource connectionSource, Dao<?,?> dao)
NOTE: By default this registers the DAO to be associated with the class that it uses. If you need to
register multiple dao's that use different DatabaseTableConfig
s then you should use
registerDaoWithTableConfig(ConnectionSource, Dao)
.
NOTE: You should maybe use the DatabaseTable.daoClass()
and have the DaoManager construct the DAO
if possible.
public static void unregisterDao(ConnectionSource connectionSource, Dao<?,?> dao)
public static void registerDaoWithTableConfig(ConnectionSource connectionSource, Dao<?,?> dao)
registerDao(ConnectionSource, Dao)
but this allows you to register it just with its
DatabaseTableConfig
. This allows multiple versions of the DAO to be configured if necessary.
