Interface INestedPersist

Interface to be implemented by objects that are to take place in a nested persist (INSERT/UPDATE to the database).

Namespace: SuperOffice.Data

Assembly: SoDataBase.dll

Syntax

public interface INestedPersist

Remarks

This interface support rather complex save operations. Through a 6-step process a set of related objects can take part of a save operation. All objects taking part of the nested save process should implement this interface.

In addition to exposing the 6-step save process, this interface also expose a method for the save process itself, and a property to check if the object is dirty (in need of an SQL UPDATE).

Properties

IsDeleted

Gets a value indicating whether this instance is deleted.

Declaration

bool IsDeleted { get; }

Property Value

Type	Description
bool	true if this instance is deleted; otherwise, false.

Remarks

This interface support rather complex save operations. Through a 6-step process a set of related objects can take part of a save operation. All objects taking part of the nested save process should implement this interface.

In addition to exposing the 6-step save process, this interface also expose a method for the save process itself, and a property to check if the object is dirty (in need of an SQL UPDATE).

IsDirty

Is the object dirty?

Declaration

bool IsDirty { get; }

Property Value

Type	Description
bool	true if dirty; otherwise, false.

Remarks

This interface support rather complex save operations. Through a 6-step process a set of related objects can take part of a save operation. All objects taking part of the nested save process should implement this interface.

In addition to exposing the 6-step save process, this interface also expose a method for the save process itself, and a property to check if the object is dirty (in need of an SQL UPDATE).

IsMarkedForDelete

Gets or sets a value indicating whether this instance is marked for delete.

Declaration

bool IsMarkedForDelete { get; set; }

Property Value

Type	Description
bool	true if this instance is marked for delete; otherwise, false.

Remarks

This interface support rather complex save operations. Through a 6-step process a set of related objects can take part of a save operation. All objects taking part of the nested save process should implement this interface.

In addition to exposing the 6-step save process, this interface also expose a method for the save process itself, and a property to check if the object is dirty (in need of an SQL UPDATE).

IsSaving

Is the nested persist in a saving state, hence disable Sentry when reading id's

Declaration

bool IsSaving { get; }

Property Value

Type	Description
bool	true if this instance is saving; otherwise, false.

Remarks

This interface support rather complex save operations. Through a 6-step process a set of related objects can take part of a save operation. All objects taking part of the nested save process should implement this interface.

In addition to exposing the 6-step save process, this interface also expose a method for the save process itself, and a property to check if the object is dirty (in need of an SQL UPDATE).

Methods

OnIdUpdate()

Update related objects with correct id's to make sure that relations are consistent before saving to the database.

Declaration

void OnIdUpdate()

Remarks

This interface support rather complex save operations. Through a 6-step process a set of related objects can take part of a save operation. All objects taking part of the nested save process should implement this interface.

In addition to exposing the 6-step save process, this interface also expose a method for the save process itself, and a property to check if the object is dirty (in need of an SQL UPDATE).

OnPreIdUpdate()

Allow for "fake id's" to be forced upon related objects.

Declaration

void OnPreIdUpdate()

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

void OnPrimaryKeyRequest(PKContainer pkContainer)

Parameters

Type	Name	Description
PKContainer	pkContainer	Collection of objects getting a primary key.

Remarks

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

OnPrimaryKeyUpdate(PKContainer)

Update primary key.

Declaration

void OnPrimaryKeyUpdate(PKContainer pkContainer)

Parameters

Type	Name	Description
PKContainer	pkContainer	Collection of objects getting a primary key.

Remarks

This interface support rather complex save operations. Through a 6-step process a set of related objects can take part of a save operation. All objects taking part of the nested save process should implement this interface.

In addition to exposing the 6-step save process, this interface also expose a method for the save process itself, and a property to check if the object is dirty (in need of an SQL UPDATE).

OnSave(BatchSave)

Add the object to the collection of objects that are to be saved within the transaction.

Declaration

void OnSave(BatchSave batchSave)

Parameters

Type	Name	Description
BatchSave	batchSave	An object holding all the objects that needs to be persisted.

Remarks

This interface support rather complex save operations. Through a 6-step process a set of related objects can take part of a save operation. All objects taking part of the nested save process should implement this interface.

In addition to exposing the 6-step save process, this interface also expose a method for the save process itself, and a property to check if the object is dirty (in need of an SQL UPDATE).

OnSaved(bool)

Called after the save operation has completed. A boolean value is passed to notify whether or not the save operation succeeded. The complete save operation is rolled back if Save operation failed.

Declaration

void OnSaved(bool bSucceeded)

Parameters

Type	Name	Description
bool	bSucceeded	True if the save operation succeeded and false if the save operation failed and rolled back.

Remarks

This interface support rather complex save operations. Through a 6-step process a set of related objects can take part of a save operation. All objects taking part of the nested save process should implement this interface.

In addition to exposing the 6-step save process, this interface also expose a method for the save process itself, and a property to check if the object is dirty (in need of an SQL UPDATE).

Save()

Save all the contained objects to the database.

Declaration

void Save()

Remarks

<p>

Save contained objects to the database:

SetSaveOwner(INestedPersist)

Force the save operation to be handled by someone else.

Declaration

void SetSaveOwner(INestedPersist saveOwner)

Parameters

Type	Name	Description
INestedPersist	saveOwner	The object to handle the save operation.

Remarks

This interface support rather complex save operations. Through a 6-step process a set of related objects can take part of a save operation. All objects taking part of the nested save process should implement this interface.

In addition to exposing the 6-step save process, this interface also expose a method for the save process itself, and a property to check if the object is dirty (in need of an SQL UPDATE).

Events

OnElementIdUpdate

Event Type

Type	Description
OnIdUpdate

Remarks

This interface support rather complex save operations. Through a 6-step process a set of related objects can take part of a save operation. All objects taking part of the nested save process should implement this interface.

In addition to exposing the 6-step save process, this interface also expose a method for the save process itself, and a property to check if the object is dirty (in need of an SQL UPDATE).
