UnitOfWork2 Class

UnitOfWork2 class. Can collect actions to perform on the entities/entity collections specified. Will not perform these actions until Commit(transaction) is called. A UnitOfWork is meant to make development easier. It will not prohibit the developer to persist the actions also using other methods. Adapter Specific.

Properties

	Name	Description
	CommitOrder	Gets / sets the Commit Order of the various blocks the unit of work groups the elements in.
	IsEmpty	Gets whether the unit of work is empty
	OptimizedSerialization	Obsolete. Gets / sets the OptimizedSerialization flag. Default: true. When set to false, the serialization logic will simply serialize all entities inside the unit of work. When set to true, the unit of work will first calculate the save queues, which weeds out entities which aren't changed and won't be saved anyway, so these don't have to be sent over the wire.

Methods

	Name	Description
	AddCallBack(Delegate, UnitOfWorkCallBackScheduleSlot, Object)	Adds the call back passed in, to the slot specified with the parameters specified.
	AddCallBack(Delegate, UnitOfWorkCallBackScheduleSlot, Boolean, Object)	Adds the call back passed in, to the slot specified with the parameters specified.
	AddCollectionForDelete	Adds the collection with entities for deletion.
	AddCollectionForSave(IEntityCollection2)	Adds the collection with entities for saving. No recursion and no refetch are done for these entities.
	AddCollectionForSave(IEntityCollection2, Boolean, Boolean)	Adds the collection with entities for saving.
	AddDeleteEntitiesDirectlyCall(String, IRelationPredicateBucket)	Adds a DeleteEntitiesDirectly call to be scheduled during Commit. It is called right after the last entity has been deleted but before the post delete callbacks are called.
	AddDeleteEntitiesDirectlyCall(Type, IRelationPredicateBucket)	Adds a DeleteEntitiesDirectly call to be scheduled during Commit. It is called right after the last entity has been deleted but before the post delete callbacks are called.
	AddForDelete(IEntity2)	Adds the passed in entity for deletion.
	AddForDelete(IEntity2, IPredicateExpression)	Adds the passed in entity for deletion.
	AddForSave(IEntity2)	Adds the passed in entity for saving. No refetching will be applied.
	AddForSave(IEntity2, IPredicateExpression)	Adds the passed in entity for saving. No refetching will be applied.
	AddForSave(IEntity2, Boolean)	Adds the passed in entity for saving.
	AddForSave(IEntity2, IPredicateExpression, Boolean)	Adds the passed in entity for saving.
	AddForSave(IEntity2, IPredicateExpression, Boolean, Boolean)	Adds the passed in entity for saving.
	AddUpdateEntitiesDirectlyCall	Adds an UpdateEntitiesDirectly call to be scheduled during Commit. It is called right after the last entity has been updated but before the pre delete callbacks are called.
	Commit(IDataAccessAdapter)	Commits this unit of work. It will first add all entities in the added collections to the correct bins, then it will start by first inserting all new entities, then saving all updates and then performing the deletes.
	Commit(IDataAccessAdapter, Boolean)	Commits this unit of work. It will first add all entities in the added collections to the correct bins, then it will start by first inserting all new entities, then saving all updates and then performing the deletes.
	CommitAsync(IDataAccessAdapter)	Async variant of Commit(IDataAccessAdapter). Commits this unit of work. It will first add all entities in the added collections to the correct bins, then it will start by first inserting all new entities, then saving all updates and then performing the deletes.
	CommitAsync(IDataAccessAdapter, Boolean)	Async variant of Commit(IDataAccessAdapter, Boolean). Commits this unit of work. It will first add all entities in the added collections to the correct bins, then it will start by first inserting all new entities, then saving all updates and then performing the deletes.
	CommitAsync(IDataAccessAdapter, CancellationToken)	Async variant of Commit(IDataAccessAdapter). Commits this unit of work. It will first add all entities in the added collections to the correct bins, then it will start by first inserting all new entities, then saving all updates and then performing the deletes.
	CommitAsync(IDataAccessAdapter, Boolean, CancellationToken)	Async variant of Commit(IDataAccessAdapter, Boolean). Commits this unit of work. It will first add all entities in the added collections to the correct bins, then it will start by first inserting all new entities, then saving all updates and then performing the deletes.
	ConstructSaveProcessQueues	Constructs the save process queues for insert and update actions. These queues are constructed from the entities added to this UoW for save either individually or in a collection. Call this method to determine what the sequence will be for the insert and update actions executed during Commit(). Commit() uses this method as well as well as the serialization/deserialization logic, to avoid sending large object graphs with few changes.
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetCollectionElementsToDelete	Gets the UnitOfWorkCollectionElement2s with the collections which are added with AddCollectionForDelete, in a new List. To remove a collection, call RemoveCollectionFromUoW(IEntityCollection2)
	GetCollectionElementsToSave	Gets the UnitOfWorkCollectionElement2s with the collections which are added with AddCollectionForSave, in a new List. To remove a collection, call RemoveCollectionFromUoW(IEntityCollection2)
	GetEntityElementsToDelete	Gets the UnitOfWorkElement2s with the entities which are added with AddForDelete, in a new List. To remove an entity, call RemoveFromUoW(IEntity2)
	GetEntityElementsToInsert	Gets the UnitOfWorkElement2s with the entities which are added with AddForSave and which are new, in a new List. To remove an entity, call RemoveFromUoW(IEntity2)
	GetEntityElementsToUpdate	Gets the UnitOfWorkElement2s with the entities which are added with AddForSave and which are not new, in a new List. To remove an entity, call RemoveFromUoW(IEntity2)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetInsertQueue	Gets the insert queue, which is a list of ActionQueueElement(of IEntity2) objects which have been placed in the insert queue. This queue is empty unless ConstructSaveProcessQueues has been called, or Commit has been called, which calls ConstructSaveProcessQueues under the hood. If this method is called after Commit, and Commit succeeded, the entities in the queue returned are saved succesfully. Calling Reset will not clear the queues, only ConstructSaveProcessQueues or Commit will.
	GetObjectData	Populates a SerializationInfo with the data needed to serialize the target object.
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	GetUpdateQueue	Gets the update queue, which is a List of ActionQueueElements(Of IEntity2) objects which have been placed in the update queue. This queue is empty unless ConstructSaveProcessQueues has been called, or Commit has been called, which calls ConstructSaveProcessQueues under the hood. If this method is called after Commit, and Commit succeeded, the entities in the queue returned are saved succesfully. Calling Reset will not clear the queues, only ConstructSaveProcessQueues or Commit will.
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	RemoveCollectionFromUoW	Removes the specified entity collection from this UnitOfWork.
	RemoveFromUoW	Removes the specified entity from this UnitOfWork. If the entity is in an added collection, the entity will later on still be added.
	Reset	Resets the inner contents of this unit of work.
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Explicit Interface Implementations

	Name	Description
	IXmlSerializableGetSchema	This method is reserved and should not be used. When implementing the IXmlSerializable interface, you should return null (Nothing in Visual Basic) from this method, and instead, if specifying a custom schema is required, apply the XmlSchemaProviderAttribute to the class.
	IXmlSerializableReadXml	Generates an object from its XML representation.
	IXmlSerializableWriteXml	Converts an object into its XML representation.
	IUnitOfWorkCoreAddCollectionForDelete	Adds the collection with entities for deletion.
	IUnitOfWorkCoreAddCollectionForSave(IEntityCollectionCore)	Adds the collection with entities for saving. No recursion and no refetch are done for these entities.
	IUnitOfWorkCoreAddCollectionForSave(IEntityCollectionCore, Boolean, Boolean)	Adds the collection with entities for saving.
	IUnitOfWorkCoreAddForDelete	Adds the passed in entity for deletion.
	IUnitOfWorkCoreAddForSave(IEntityCore)	Adds the passed in entity for saving. No refetching will be applied. Save is recursive.
	IUnitOfWorkCoreAddForSave(IEntityCore, Boolean)	Adds the passed in entity for saving. No refetching will be applied. Save is recursive.
	IUnitOfWorkCoreCommit(ITransactionController)	Commits this unit of work. It will first add all entities in the added collections to the correct bins, then it will start by first inserting all new entities, then saving all updates and then performing the deletes. This order can be controlled by the constructor of the unit of work which allows users to define a different work order.
	IUnitOfWorkCoreCommit(ITransactionController, Boolean)	Commits this unit of work. It will first add all entities in the added collections to the correct bins, then it will start by first inserting all new entities, then saving all updates and then performing the deletes. This order can be controlled by the constructor of the unit of work which allows users to define a different work order.
	IUnitOfWorkCoreCommitAsync	Async variant of Commit(ITransactionController) Commits this unit of work. It will first add all entities in the added collections to the correct bins, then it will start by first inserting all new entities, then saving all updates and then performing the deletes. This order can be controlled by the constructor of the unit of work which allows users to define a different work order.
	IUnitOfWorkCoreReset	Resets the inner contents of this Unit of work object
