Methods
GetFacadingItems()
Implement this method to expose items that needs to be persisted.
Declaration
protected abstract IEnumerable<INestedPersist> GetFacadingItems()Returns
| Type | Description |
|---|---|
| System.Collections.Generic.IEnumerable<INestedPersist> | Collection of items that needs to be persisted. |
OnIdUpdate()
Update related objects with correct id's to make sure that relations are consistent before saving to the database.
Declaration
protected override void OnIdUpdate()Overrides
OnPreIdUpdate()
Allow for "fake id's" to be forced upon related objects.
Declaration
protected override void OnPreIdUpdate()Overrides
Remarks
In order to figure out which objects taking part of the nested save operation that actually needs to be saved, this method allows for "fake id's" to be forced upon related objects. Upon receiving the "fake id", the objects receiving such an id can determine if they needs to be persisted (e.g. saved) to the database. However, the fake id's forced upon related objects must be set to correct id's in the OnIdUpdate method taking place later in the save operation.
OnPrimaryKeyRequest(PKContainer)
Allow the object to add itself to a collection of requests for primary keys.
Declaration
protected override void OnPrimaryKeyRequest(PKContainer pkContainer)Parameters
| Type | Name | Description |

When implementing this method, add yourself to the collection if you need a new primary key.
OnPrimaryKeyUpdate(PKContainer)

Declaration
protected override void OnPrimaryKeyUpdate(PKContainer pkContainer)Parameters
| Type | Name | Description |

Add the object to the collection of objects that are to be saved within the transaction.
Declaration
protected override void OnSave(BatchSave batchSave)Parameters
| Type | Name | Description |
