The general goal for this version is to implement various features
described by these issues in our issue tracker:
-- #8963: Support for composite IDs.
- #10151: Improved Database and PersistentObject datatype support (especially
binary data).
- #10373: Several relations to the same table for PersistentObject.

Each of the issues and their proposed solutions are explained in a seperate

-Support for composite IDs (and composite properties in general) [#8963]
-=======================================================================
-
-Note: This section is not finished. Please read the discussion on the bug to
-see if it will be implemented at all.
-
-Background
-----------
-
-Currently PersistentObject only supports single primary keys for the underlying
-database structure through the definition struct
-ezcPersistentObjectIdProperty. This proposal adds a mechanism to
-PersistentObject to support primary keys that consist of several table columns.
-
-TODO: Discuss difference between composite and multi column. We want
-multicolumn keys and composite properties. Split into one more task.
-
-Design
-------
-
-::
- ezcPersistentObjectColumn
- {
- public $columnName;
- public $columnType;
- }
-
- ezcPersistentObjectIdProperty
- {
- // deprecated
- public $columnName;
- public $visibility;
-
- // ezcPersistentObjectColumn
- public $column;
- }
-
- ezcPersistentObjectMultiColumnId
- {
- // array of ezcPersistentObjectIdProperty
- public $ids;// Note: automatic text generator on the ids.
- // This is because any form of sequence
- // does not make sense. (Unless someone
- // can tell me otherwise and tell me how
- // to specify/implement that... :)
- }
-
- ezcPersistentCompositeProperty
- {
- // array of ezcPersistentObjectColumn
- public $columns;
- public $filter; // covered by different spec.
- public $propertyName;
- public $propertyType;
- }
-
- Required API changes:
- ezcPersistentIdentifierGenerator::postSave() if we want to use it to
return the ids. (Like we do now)
- ezcPersistentSession::load( $class, $id ) since $id can now be composite
- ezcPersistentSession::loadIfExist( $class, $id ) since $id can now be
composite
- ezcPersistentSession::loadIntoObject( $pObject, $id ) since $id can now be
composite
