NonPersistentObjectSpace Members

An Object Space used to manage non-persistent objects.

Constructors

Name Description
NonPersistentObjectSpace(ITypesInfo, IEntityStore) Creates a new instance of the NonPersistentObjectSpace class.
NonPersistentObjectSpace(ITypesInfo) Creates a new instance of the NonPersistentObjectSpace class.

Fields

Name Description
AllowFilterObjectsByDefault static
AutoCommitAdditionalObjectSpacesByDefault static Specifies whether a non-persistent Object Space’s CommitChanges() method forces additional Object Spaces to commit their changed persistent objects. When this property is set to true, changes to persistent objects that belong to additional Object Spaces mark the NonPersistentObjectSpace as modified. This field affects all non-persistent Object Spaces in your application if you do not specify the AutoCommitAdditionalObjectSpaces property for a particular Object Space.
AutoDisposeAdditionalObjectSpacesByDefault static Specifies whether non-persistent Object Spaces dispose of their inner Object Spaces from the AdditionalObjectSpaces collection when they dispose of themselves. This field affects all non-persistent Object Spaces in your application if you do not specify the AutoDisposeAdditionalObjectSpaces property for a particular Object Space.
AutoRefreshAdditionalObjectSpacesByDefault static Specifies whether non-persistent Object Spaces refresh their inner Object Spaces from the AdditionalObjectSpaces collection when refreshing themselves. This field affects all non-persistent Object Spaces in your application if you do not specify the AutoRefreshAdditionalObjectSpaces property for a particular Object Space.
AutoSetModifiedOnObjectChangeByDefault static Specifies whether non-persistent Object Spaces add objects to the ModifiedObjects collection when these objects raise the PropertyChanged event. This field affects all non-persistent Object Spaces in your application if you do not specify the AutoSetModifiedOnObjectChange property for a particular Object Space.
CompositeKeyPropertyType static For internal use. Inherited from BaseObjectSpace.
ThrowExceptionForNotRegisteredEntityType static Certain Object Space methods have the Type parameters. This static field indicates whether these methods throw the ArgumentException when a passed type is not registered in the Object Space Provider’s entity store. Set this field to true to diagnose issues related to the incorrect use of the Object Space type (for example, when a persistent Object Space is used to manipulate non-persistent objects). Inherited from BaseObjectSpace.
UseKeyComparisonToDetermineIdentity static For internal use.
