where TEntity : class, IEntityIdentifier, IEntityLastUpdate

Public Class MemoryArchive(Of TEntity As {Class, IEntityIdentifier, IEntityLastUpdate})
	Inherits TrackingArchive(Of TEntity)

Type Parameters

TEntity: The entity type to archive.

The MemoryArchive<TEntity> type exposes the following members.

Constructors

	Name	Description
	MemoryArchive<TEntity>(TransactionContext)	Construct a new instance with the provided context.
	MemoryArchive<TEntity>(TransactionContext, TrackingTypeArchiverCollection)	Construct a new instance with the provided context and type archivers.

Properties

	Name	Description
	Context	Gets the context for which to archive entities. (Inherited from TrackingArchive<TEntity>.)
	IsRunning	Gets a value indicating whether the archiver is currently archiving changes to entities in the Context. (Inherited from TrackingArchive<TEntity>.)
	MaximumQueueLength	Gets or sets the maximum length of the queue of committed transactions to be archived. If transactions are committed at a higher rate than they can be archived, the length of the queue will grow. When it reaches this maximum length, committing threads will block until the archiver catches up. Setting this value too high will result in excessive memory usage. Changes to this value while the archiver IsRunning will not take effect until it is restarted. (Inherited from TrackingArchive<TEntity>.)
	PrimitivePropertyComponents	Gets a list of the primitive components of the properties for this entity type. Each property in Properties will correspond to one or more properties in this collection. For example, a property in Properties of type JulianDate might have two properties in this collection: an integer called "Day" and a double called "SecondsOfDay". The exact relationship between Properties and this collection is dictated by the TypeArchivers being used by this archive. (Inherited from TrackingArchive<TEntity>.)
	Properties	Gets a list of archived properties for this entity type. There is one property in this collection for each property in the entity's EntitySchema<TEntity>. (Inherited from TrackingArchive<TEntity>.)
	TypeArchivers	Gets the collection of TrackingTypeArchivers that is used to archive the properties of entities. The returned instance should be considered read-only. Attempts to modify the collection of archivers will result in an ObjectFrozenException. (Inherited from TrackingArchive<TEntity>.)

Methods

	Name	Description
	ArchiveEntities	Archives a set of entities. (Overrides TrackingArchive<TEntity>.ArchiveEntities(Transaction, IEnumerable<TEntity>).)
	Clear	Clears the contents of the archive. (Overrides TrackingArchive<TEntity>.Clear().)
	Deserialize	Deserializes the archive from the provided stream.
	Dispose()	Releases any resources associated with this instance. (Inherited from TrackingArchive<TEntity>.)
	Dispose(Boolean)	Releases any resources associated with this instance. (Inherited from TrackingArchive<TEntity>.)
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetArchivedData(JulianDate, JulianDate, Int32,String[])	Retrieves archived properties for all entities over the provided time period. (Inherited from TrackingArchive<TEntity>.)
	GetArchivedData(Object, JulianDate, JulianDate, Int32,String[])	Retrieves archived properties for the provided entity over the provided time period. (Inherited from TrackingArchive<TEntity>.)
	GetArchivedInterval()	Gets the overall interval that exists in the archive for any entity. (Overrides TrackingArchive<TEntity>.GetArchivedInterval().)
	GetArchivedInterval(Object)	Gets the overall interval that exists in the archive for the specified entity identifier. (Overrides TrackingArchive<TEntity>.GetArchivedInterval(Object).)
	GetArchivedPrimitivePropertyComponents(IEnumerable<ArchivedProperty>, JulianDate, JulianDate, Int32)	Retrieves archived primitive property components for all entities over the provided time period. (Overrides TrackingArchive<TEntity>.GetArchivedPrimitivePropertyComponents(IEnumerable<ArchivedProperty>, JulianDate, JulianDate, Int32).)
	GetArchivedPrimitivePropertyComponents(Object, IEnumerable<ArchivedProperty>, JulianDate, JulianDate, Int32)	Retrieves archived primitive property components for the provided entity over the provided time period. (Overrides TrackingArchive<TEntity>.GetArchivedPrimitivePropertyComponents(Object, IEnumerable<ArchivedProperty>, JulianDate, JulianDate, Int32).)
	GetEntityPrimitivePropertyComponents	Fills an array with the archived properties of an entity. (Inherited from TrackingArchive<TEntity>.)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetMotion<T>(Object, JulianDate, JulianDate,String[])	Gets time-varying data, such as position and velocity, from the archive. (Inherited from TrackingArchive<TEntity>.)
	GetMotion<T>(Object, JulianDate, JulianDate, Int32,String[])	Gets time-varying data, such as position and velocity, from the archive. (Inherited from TrackingArchive<TEntity>.)
	GetOrientations(Object, JulianDate, JulianDate)	Gets a DateMotionCollection<T, TDerivative> representing the archived orientation, rotational velocity and rotational acceleration of the specified entity beginning at the specified time and lasting for the specified duration. (Inherited from TrackingArchive<TEntity>.)
	GetOrientations(Object, JulianDate, Int32)	Gets a DateMotionCollection<T, TDerivative> representing the archived orientation, rotational velocity and rotational acceleration of the specified entity beginning at the specified time and lasting for the specified duration. (Inherited from TrackingArchive<TEntity>.)
	GetOrientations(Object, JulianDate, JulianDate, Int32)	Gets a DateMotionCollection<T, TDerivative> representing the archived orientation, rotational velocity and rotational acceleration of the specified entity beginning at the specified time and lasting for the specified duration. (Inherited from TrackingArchive<TEntity>.)
	GetPositions(Object, JulianDate, JulianDate)	Gets a DateMotionCollection<T> representing the archived position, velocity and acceleration of the specified entity beginning at the specified time and lasting for the specified duration. (Inherited from TrackingArchive<TEntity>.)
	GetPositions(Object, JulianDate, Int32)	Gets a DateMotionCollection<T> representing the archived position, velocity and acceleration of the specified entity beginning at the specified time and lasting for the specified duration. (Inherited from TrackingArchive<TEntity>.)
	GetPositions(Object, JulianDate, JulianDate, Int32)	Gets a DateMotionCollection<T> representing the archived position, velocity and acceleration of the specified entity beginning at the specified time and lasting for the specified duration. (Inherited from TrackingArchive<TEntity>.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	Serialize	Serializes the archive to the provided stream.
	StartWriting	Starts the archiver. After this method is called, all updates to entities in the Context will be archived. (Inherited from TrackingArchive<TEntity>.)
	StopWriting	Stops the archiver. After this method is called, updates to entities in the Context will no longer be archived. This method does not return until the current queue of updates to archive has been processed. (Inherited from TrackingArchive<TEntity>.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)
	WaitForArchiveQueue	Waits for the currently queued transactions to be archived before returning. Additional committed transactions may be queued while waiting and these will NOT be waited upon. (Inherited from TrackingArchive<TEntity>.)
	WritingShutdown	Called during StopWriting(), after the last call to ArchiveEntities(Transaction, IEnumerable<TEntity>). (Inherited from TrackingArchive<TEntity>.)
	WritingStartup	Called during StartWriting(), before the first call to ArchiveEntities(Transaction, IEnumerable<TEntity>). (Inherited from TrackingArchive<TEntity>.)
