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.

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 the cache. |

createDao(ConnectionSource connectionSource,
Class<T> clazz)
Helper method to create a Dao object without having to define a class. |

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. |

NOTE: It is better to use the DatabaseTable.daoClass() and have the DaoManager construct the DAO
if possible.
