InstanceView Class

Definition

Represents a view of an instance. For example, the Execute(InstanceHandle, InstancePersistenceCommand, TimeSpan) method implementations return an InstanceView object that provides a view into the instance data in the persistence store.

public ref class InstanceView sealed
public sealed class InstanceView
type InstanceView = class
Public NotInheritable Class InstanceView
Inheritance
InstanceView

Remarks

Each InstanceView object is associated with an InstanceHandle. For an InstanceView returned from InstanceStore.Execute, the associated handle is the one passed to Execute. For an InstanceView returned from InstancePersistenceContext.InstanceView, the associated handle is the one passed to TryCommand.

An InstanceHandle may have zero or more InstanceView objects associated with it at any given time. InstanceView objects returned from InstanceStore.Execute are immutable and represent a snapshot of the known instance state after the successful execution of that command. InstanceView objects returned from InstancePersistenceContext are mutable and represent the current known instance state as it is being updated during the execution of the command. (If the command ultimately fails, this intermediate state is discarded).

Properties

InstanceData

Gets instance data as a dictionary of names and values.

InstanceDataConsistency

Gets the consistency status of the InstanceData property.

InstanceId

Gets the identifier (ID) of the instance as a GUID.

InstanceKeys

Gets the instance keys as a dictionary of instance key identifiers and associated InstanceKeyView objects.

InstanceKeysConsistency

Gets the consistency status of the InstanceKeys property.

InstanceMetadata

Gets the metadata of an instance as a dictionary of names and InstanceValue objects.

InstanceMetadataConsistency

Gets the consistency status of the InstanceMetadata property.

InstanceOwner

Gets the owner of the instance.

InstanceOwnerMetadata

Gets the metadata for an instance owner as a dictionary of names and values.

InstanceOwnerMetadataConsistency

Gets the consistency status of the InstanceOwnerMetadata property.

InstanceState

Gets the state of the instance (Unknown, Uninitialized, Initialized, or Completed).

InstanceStoreQueryResults

Gets a collection of InstanceStoreQueryResult objects. The collection is automatically reset to empty each time a command is executed against the associated instance handle.

IsBoundToInstance

Returns a value that indicates whether the associated instance handle is bound to an instance.

IsBoundToInstanceOwner

Returns a value that indicates whether the associated instance handle is bound to an instance owner.
