Update History:
v1.0.8 ===========================================
* New "Omega" NPath engine replaces old "Alpha" Engine
- Single join path tree in sql generated by npath
- Left outer joins generated when traversing nullable columns in spans
- Support for functions
- Improved span loading
- Parameterized queries
* New ObjectQueryEnine evaluates NPath queries on lists of objects in memory
- Filters a supplied list of objects or all objects in cache
* New IContext.FilterObjects() Method
- FilterObjects(npath, type, objects) filters the passed in list of objects
- FilterObjects(npath, type) filters the objects in cache
- FilterObjects(npath, type, merginBehavior) begins by querying
the database and then continues by querying the cache,
merging the results.
* New OverLoads on IContext.GetObjects() method
* New constructors on Context allow using embedded xml mapping files
* Performance optimizations on object management
-Additional caching is used to speed up retreival of Object and Property Status
-Additional caching is used in the DomainMap (using the IMap.Fixate() method)
* New IContext.GetDataTable() method returns results in form of DataTable
* UnitOfWork updated to handle inserts with cyclic references
* All generated Sql queries are parameterized
* New IContext.AutoTransactions property (default = True)
- When true, a local transaction will automatically be used whenever a call
to context.PersistAll() is made, if the domain maps to only one
database and if the user has not already manuall started a pending
transaction with context.BeginTransaction()
* Added OnBefore- and OnAfter- events for Begin-, Commit- and RollbackTransaction
* Added ILogger interface and Logger base class for logging
* Reworked Observer system, making the ObservingAttribute obsolete
- context.AddObserver(observer) - adds observer observing context and all objects
- context.AddObserver(observer, type) - adds observer observing all objects of given type
- context.AddObserver(observer, obj) - adds observer observing object
- context.AddObserver(observer, params object[]) - adds observer observing given objects and types
- context.AddObserver(observer, observerTarget) - adds observer observing all objects, the context or both
v1.0.7 ===========================================
* New runtime subclassing of lists by Roger Johansson
- Including support for typed lists
* Both sides of bi-directional properties are now read-write
(though one side should still be marked as
read-only in the xml mapping file)
* Old inverse manager changes name to OnPersistInverseManager
(this manager uses the strategy of synching after persist)
* New OnWriteInverseManager - becomes default inverse manager
(this manager uses the strategy of synching directly on write)
* The old InverseManager class becomes a broker between the two classes
* Select which inverse manager to use by setting the new
Context.InverseManager.InverseManagerType property.
* ManagedList changes name to InterceptableList
(ManagedList is still there, and inherits from
InterceptableList, so your old code will work,
but ManagedList becomes obsolete without error)
* New IInterceptableList interface
Note: For the new features to work, you must leave your
list properties empty (not create an instance of a list class
for them as default value) since NPersist wants to create all
list class instances in your list properties. As of v1.0.7,
NPersist will fill all your list properties with InterceptableLists.
That is, declare your list member variables as:
private IList m_Employees;
not
private IList m_Employees = new ArrayList;
v1.0.6 ===========================================
* Translated the whole thing to C#
* POCO support with runtime subclassing, thanks to Roger Johansson!
* Added new overload CreateObject(id, type) method that returns new instance
(required to use this instead of old CreateObject(obj) for POCO)
* Added new assembly-name attribute to domain and class elements in xml file
(required if the name of your assembly is
different from the name of your domain)
* Changed name from IContextManager and ContextManager to just
IContext and Context (the old ones still exist but are marked
as obsolete (with no error), and just inherit from IContext
and Context)
* IContextHolder and ContextHolder are now obsolete with error
They are not needed anymore with the new POCO support
but if you want to do what you did with these before,
use the new IInterceptable and Interceptable instead
* Added IContextFactory and ContextFacory interface/class
* Moved ValidationManager from a property in context to a
property in the EventManager
* Added IObjectFactory and ObjectFactory
* Added IInterceptor and Interceptor classes
* Added IContextManager.GetConnectionString() and SetConnectionString() methods
* Added IContextManager.TryGetObject() method
* Added IContextManager.TryGetObjectByKey() method
* Added IContextFactory interface and ContextFactory base class
* Added IPersistenceEngine interface
* Fixed NPath so that:
- It now allows quotes in strings, ex:
"Select * from Employee where name = 'O''Neal'"
- It now handles strings that match reserved words, ex:
"Select * from Employee where name = 'Select'"
