An object of this type is returned by AllObjectsT(Boolean, Boolean) or AllObjectsT(Boolean)

Iterator of type AllObjectsT

A few extensions to improve performance of Linq for Objects queries

This is the placement manager of objects persisted using Persist(Object), it is automatically created when the first object of a type is persisted. It is the first object in the database of each type mapped Database.

Represents a Database which corresponds to file system file.

Represents a host and a directory in which a range of databases are stored. The range is a database number range.

Maintains collections of all existing DatabaseLocations.

Object maintains a list of pages accessed by a session, pages are removed from the list when there is not enough memory available. This makes such pages eligible for garbage collection while in list pages are prevented from being garbage collected.

Contains a list of possible license attributes for licensing VelocityDb class library and server

An object of this type is a base class of type returned by AllObjectsT(Boolean, Boolean) or AllObjectsT(Boolean)

Iterator for type OfType

A few extensions to improve performance of Linq for Objects queries

Base class for all persistent capable classes except for embedded objects which do not need to be subclasses of this class.

Each Database consist of a number of variable sized pages. A page can be compressed and may be encrypted and contains one or more objects. Page compression is controlled by the DatabaseLocation of the Database containing a page. Each page has a PageInfo that provides info about a page and can be updated to turn on/off compression and encryption for a specific page.

Maintains string references to Pages within a Database

Each Page has a PageInfo that provides info about a page and can be used to turn on/off compression and encryption for a page.

Internally Used within VelocityDB and its extensions

This class is used when deciding where to place a new object persistently. That is we have a choice of database number, page number and page number. There is other ways to control the placement including ObjectsPerPage, PagesPerDatabase, and it is also possible to override Persist(Placement, SessionBase, Boolean, Boolean, QueueIOptimizedPersistable).

Tracks references to this object and signals ReferentialIntegrityException if unpersisted before while still being referenced.

When a persistent object is opened, all its referenced objects are opened as well. In order to limit the number of opened objects, you need to use this class. A reference from an instance of this class will not cause the referenced object to be opened. It will be opened when you ask for it.

This is the base class for all weak references.

Deprecated, use WeakIOptimizedPersistableReference instead (so name conflict can be avoided) When a persistent object is opened, all its referenced objects are opened as well. In order to limit the number of opened objects, you need to use this class. A reference from an instance of this class will not cause the referenced object to be opened. It will be opened when you ask for it. The Type of the weak referenced object, must be OptimizedPersistable

The object identifier containing a 32 bit database part, a 16 bit page part and a 16 bit page part. These parts are combined into a 64bit unsigned number Id.

The short object identifier containing a 16 bit page part and a 16 bit page part. This is used for short references within a single databases.

add optimized persistence by implementing this interface. We provide OptimizedPersistable as a base class that implements this interface.

Maintains a set of all References to this object

Choices for object caching

Flag bits for a persistent object

Selection of choices foe Page compression.

Use desEncrypted for encrypted pages, set encryption private key in DatabaseLocation. Use noEncryption when no encryption is desired. Other choices in this enum are not yet publicly available. Other kinds of encryption can be provided upon request. We can even make the interface public allowing application defined encryption.
