An instance identifier. Must not be Guid.Empty. The instance handle.

Creates an instance handle. If the instance owner passed as a parameter is not null, the value is automatically bound as the new handle's instance owner. (Otherwise, no instance owner is bound, even if DefaultInstanceOwner is set.)

The owner of an instance. The instance handle. A null value indicates that the new handle should not be automatically bound to an instance owner.

An InstanceOwner object that represents the owner of an instance. Pass null as the value for this parameter to indicate that the new handle should not be automatically bound to an instance owner. An instance identifier. Must not be Guid.Empty. The instance handle.

Gets or sets the default instance owner.

The default instance owner.

Ends the asynchronous operation.

The result of the operation. An InstanceView object representing the known state of the instance after the successful completion of the command.

Ends an asynchronous operation.

The result of the operation. A persistence provider implementation should return false if it doesn't support the command passed to the BeginTryCommand method. Otherwise it should return true or throw an exception.

Ends the asynchronous operation initiated by the method.

An IAsyncResult object that was handed over to the client by the Begin method. Returns a list of objects.

Executes a persistence command synchronously. Examples of persistence commands are: and .

An instance handle. The command to be executed. The timeout value for the operation. An InstanceView object representing the known state of the instance after the successful completion of the command. If Execute was called under a transaction, this state may include uncommitted data. Once the transaction is committed successfully, the data in the InstanceView object can be considered committed

Gets all the signaled events bound to an object.

An object representing the owner of an instance. Returns an array of objects.

Gets each InstanceOwner object that is bound to a valid instance handle or has not been garbage collected.

The owner of the instance.

Invoked when an instance handle is freed.

The instance handle that was freed. The persistence provider's user context information that was returned from OnNewInstanceHandle, or null if OnNewInstanceHandle is not overridden.

Invoked when a new instance handle is created.

An instance handle. An object. This user context object will be available to the persistence provider when commands are executed using the handle, and when the handle is freed.

Resets the signaled event and removes the event from the signaled events list maintained by the instance owner.

The persistence event that was signaled earlier and to be reset. The instance owner associated with the persistence event.

An instance store invokes this method to signal an event. A workflow host that subscribes for this persistence event receives it and takes an appropriate action.

The persistence event to be signaled. The instance owner.

A persistence provider implements this method, which determines whether a particular persistence command can be executed and if the command can be executed executes it asynchronously.

The instance context. The command to be executed. Timeout value for the operation. A persistence provider implementation should return if it doesn't support the command passed as a parameter; otherwise it should return or throw an exception.

A workflow host typically invokes this method to wait for an event to be signaled.

The instance handle that is bound to the event. The time span after which the waiting operation times out. A list of objects.

Supports an extensible mechanism to provide data from an instance store. This includes data for instances, instance owners, and instance keys other than those bound to the instance handle being used. For example, a persistence provider mayprovide the owner metadata for all the instance owners in the store by passing an instance of a class derived from to the method.

Initializes an instance of the class.

Stores the information about instance data and metadata.

Initializes an instance of the class by using value object passed as a parameter.

The value object.

Initializes an instance of the class by using the value Object and the options for those values passed as parameters.

The value object. The options for the value object. For more information, see .

Gets the previously deleted value.

The previously deleted value.

Gets a value that indicates whether the object represents a deleted value.

if the object represents a deleted value; otherwise .

Gets the option for an instance value.

The option for an instance value.

Gets the instance value as an object.

The value of the instance.

Describes the consistency guarantee of the instance values contained in a specified dictionary.

Indicates that the consistency of the instance value is in doubt.

Indicates that there is no consistency guarantee.

Indicates that the consistency of the instance value is partial.

Contains options for instance values to indicate whether the instance values are write-only, optional, there are no instance values.

Indicates that there are no instance values.

Indicates that a host can function without knowing the value of this instance value.

Indicates that the instance value is write-only. The instance value can be used for administration purposes.

Represents a view of an instance. For example, the method implementations return an object that provides a view into the instance data in the persistence store.

Gets instance data as a dictionary of names and values.

The instance data.

Gets the consistency status of the InstanceData property.

The consistency (None, In Doubt, and Partial) of the instance data. InstanceValueConsistency.None indicates that the InstanceData property holds a fully populated and locked set of instance data.

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

The ID of the instance or Guid.Empty if the associated instance handle is not bound to an instance.

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

A dictionary of instance key identifiers and their associated instance key view objects.

Gets the consistency status of the InstanceKeys property.

The consistency value of instance keys. indicates that the InstanceKeys property holds a fully populated and locked set of instance keys (though not necessarily each key's metadata).

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

The metadata of the instance.

Gets the consistency status of the InstanceMetadata property.

The consistency of the instance metadata. InstanceValueConsistency.None indicates that the InstanceMetadata property holds a fully populated and locked set of instance metadata.

Gets the owner of the instance.

The owner of the instance, or if the associated instance handle is not bound to an instance owner.

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

A dictionary containing instance-owner metadata.

Gets the consistency status of the InstanceOwnerMetadata property.

The consistency of the instance owner metadata. Returns null if the associated instance handle is not bound to an instance owner.

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

The state of the instance.

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

A collection of objects.

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

if the associated instance handle is bound to an instance; otherwise, .

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

if the associated instance handle is bound to an instance owner; otherwise, .

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

if the associated instance handle is bound to an instance lock; otherwise, .
