A quick update on LLBLGen Pro
You might have heared about the DAL generator I released
last year, LLBLGen,
which as a surprise to me, became a worldwide success (over
25,000 downloads). I'm currently busy developing its big
brother LLBLGen Pro, which should be released later this
summer. As a quick update on what this successor is capable
of, some lines of example code which uses some
generated code (entities, collections) that is produced with
an alpha version of LLBLGen Pro.
It loads a
collection of entity objects (that's right, normal entity
classes) of the type OrderDetail, from the Northwind
database, which contain references to the product with
ID '24', binds it using databinding to a datagrid in a form,
which allows full editing of the OrderDetail objects, and
after that, all changed objects are saved using an embedded
transaction to the persistent storage using a single line of
code. I think it's pretty neat :) Of course this is one of
the many ways to retrieve / construct entity objects using
the O/R mapper code generated by LLBLGen Pro. More updates
later on.
OrderDetailCollection collection = new OrderDetailCollection();
ProductEntity product = new ProductEntity(24);
// ...
collection.GetMulti(null, product);
DatabindTester dbtester = new DatabindTester();
dbtester.OrderDetailEntities = collection;
dbtester.ShowDialog();
// ...
// in the dialog:
public OrderDetailCollection OrderDetailEntities
{
get { return _orderDetailEntities; }
set
{
_orderDetailEntities = value;
binderGrid.DataSource = _orderDetailEntities;
}
}
private void saveButton_Click(object sender, System.EventArgs e)
{
_orderDetailEntities.SaveMulti();
}
All queries are generated dynamicly, all code is using several patterns like the DAO pattern and the strategy pattern. Everything is developed internally using interfaces.
