Защищенные методы

Метод	Описание
AfterSaveEntities ( Dictionary saveMap, List keyMappings ) : void	Called after the entities have been saved, and all the temporary keys have been replaced by real keys. The base implementation calls AfterSaveEntitiesDelegate, or does nothing if AfterSaveEntitiesDelegate is null.
BeforeSaveEntities ( Dictionary saveMap ) : List>.Dictionary	Called after BeforeSaveEntity, and before saving the entities to the persistence layer. Allows adding, changing, and removing entities prior to save. The base implementation returns the result of BeforeSaveEntitiesDelegate, or the unchanged saveMap if BeforeSaveEntitiesDelegate is null.
BeforeSaveEntity ( EntityInfo entityInfo ) : bool	The method is called for each entity to be saved before the save occurs. If this method returns 'false' then the entity will be excluded from the save. The base implementation returns the result of BeforeSaveEntityDelegate, or 'true' if BeforeSaveEntityDelegate is null.
BeginTransaction ( System isolationLevel ) : IDbTransaction
BuildJsonMetadata ( ) : String
CloseDbConnection ( ) : void	Internal use only. Should only be called by ContextProvider during SaveChanges. Closes the DbConnection used by the ContextProvider's implementation.
CreateEntityInfo ( ) : EntityInfo
CreateEntityInfoFromJson ( dynamic jo, Type entityType ) : EntityInfo
HandleSaveException ( Exception e, SaveWorkState saveWorkState ) : bool
InitializeSaveState ( Newtonsoft.Json.Linq.JObject saveBundle ) : void
LookupEntityType ( String entityTypeName ) : Type
OpenDbConnection ( ) : void	Internal use only. Should only be called by ContextProvider during SaveChanges. Opens the DbConnection used by the ContextProvider's implementation. Method must be idempotent; after it is called the first time, subsequent calls have no effect.

Описание методов

AfterSaveEntities() защищенный Метод

Called after the entities have been saved, and all the temporary keys have been replaced by real keys. The base implementation calls AfterSaveEntitiesDelegate, or does nothing if AfterSaveEntitiesDelegate is null.

protected AfterSaveEntities ( Dictionary saveMap, List keyMappings ) : void
saveMap	Dictionary	The same saveMap that was returned from BeforeSaveEntities
keyMappings	List	The mapping of temporary keys to real keys
Результат	void

BeforeSaveEntities() защищенный Метод

Called after BeforeSaveEntity, and before saving the entities to the persistence layer. Allows adding, changing, and removing entities prior to save. The base implementation returns the result of BeforeSaveEntitiesDelegate, or the unchanged saveMap if BeforeSaveEntitiesDelegate is null.

protected BeforeSaveEntities ( Dictionary saveMap ) : List>.Dictionary
saveMap	Dictionary	A List of EntityInfo for each Type
Результат	List>.Dictionary

BeforeSaveEntity() защищенный Метод

The method is called for each entity to be saved before the save occurs. If this method returns 'false' then the entity will be excluded from the save. The base implementation returns the result of BeforeSaveEntityDelegate, or 'true' if BeforeSaveEntityDelegate is null.

protected BeforeSaveEntity ( EntityInfo entityInfo ) : bool
entityInfo	EntityInfo
Результат	bool

BeginTransaction() защищенный Метод
