 | IObjectDbEsent Methods |
The IObjectDbEsent type exposes the following members.
Methods| Name | Description | |
|---|---|---|
 | DeleteT |
Deletes an object from the database by primary key.
|
| DeleteAllT |
Deletes all objects of a type from the database.
|
| Export |
Exports all data and schema information as an XML element to a stream. The shape and contents
of the XML is specific to each Object Database implementation. It is desirable that
the Export and Import(Stream) methods can exchange the XML.
|
| FindFirstByIndexT |
Finds the first object in the database with a property value that equals a search value.
|
| GetT |
Gets an object from the database by primary key.
|
| GetByIndexT |
Gets objects from the database by an index over a non primary key property.
Because non primary index values may not be unique, a set of results is returned.
|
| GetObjectNames |
Gets the names of all object types stored in the database.
|
| GetPropertyNames |
Gets the names of all properties stored in the database for a given object name.
|
| GetSchema |
Gets the internal structure of the object database as a shaped XML element.
This method is only intended to be used for debugging purposes and may only
be meaningful for implementations that use a backing storage which supports
the concept of a schema.
|
| Import |
Imports all data and schema information from an XML element in a stream. It is desirable that
the Import and Export(Stream) methods can exchange the XML.
|
| InsertT |
Inserts a single object into the database. Non identity primary key property
value(s) must be set. All public readable and writable property values of the inserted
item object are saved. An exception is thrown if the primary key already exists.
|
| InsertManyT |
Inserts a set of objects into the database using a single transaction. All public readable
and writable property values of the inserted item objects are saved. Non identity primary key
property value(s) must be set. An exception is thrown if the primary key of any item already exists.
|
| ListT |
Lists (enumerates) all objects of a type over the primary key index.
|
| ListT(SeekType, Object) |
Lists (enumerates) all objects of a type over the primary key index starting
at a specified seek position.
|
| ListByIndexT(String) |
Lists (enumerates) all objects of a type over an alternative key index.
|
| ListByIndexT(String, SeekType, Object) |
Lists (enumerates) all objects of a type over an alternative key index starting at
a specified seek position.
|
| SaveT |
Saves an object into the database, either adding the object if the primary key does not
exist, or replacing the data in an existing record with the primary key.
|
| UpdateT |
Updates data in an existing record by primary key. The primary key property value(s)
must be set to locate the record to be updated.
