InstanceView Class

Definition

Namespace:

System.Runtime.DurableInstancing

Assembly:

System.Runtime.DurableInstancing.dll

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