MetadataStore Class

When overridden, represents a metadata store and provides methods to obtain a replica metadata object. The replica metadata object is used to access the metadata for a specific replica. This is the abstract base class for all metadata stores that use the metadata storage service API.

Methods

	Name	Description
	BeginTransaction	When overridden in a derived class, starts an explicit transaction on the metadata store that has the specified isolation level.
	CommitTransaction	When overridden in a derived class, commits an explicit transaction that has already started on the metadata store.
	Equals	(Inherited from Object.)
	Finalize	(Inherited from Object.)
	GetHashCode	(Inherited from Object.)
	GetReplicaMetadata	When overridden in a derived class, gets the ReplicaMetadata object that represents the metadata for a particular replica.
	GetSingleReplicaMetadata	When overridden in a derived class, gets the metadata for the single replica contained in the metadata store.
	GetType	(Inherited from Object.)
	InitializeReplicaMetadata	When overridden in a derived class, creates, initializes, and saves new metadata for a replica.
	IsTransactionActive	When overridden in a derived class, indicates whether an active transaction exists on the metadata store.
	MemberwiseClone	(Inherited from Object.)
	RemoveReplicaMetadata	When overridden in a derived class, removes all metadata associated with the specified replica.
	RollbackTransaction	Cancels the current explicit transaction and rolls the metadata store back to the state it was in before the transaction was started.
	ToString	(Inherited from Object.)

Remarks

This class provides a high-level abstraction of a metadata store. The class provides methods to create or get a ReplicaMetadata object that can be used to access the actual metadata for a replica. It also provides methods for starting and stopping transactions on the metadata store.

Notes to Inheritors

When you inherit from MetadataStore, you must override all of its members.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
