Chapter 12 - VisualBasic.NET Generator

12.1 - Proof-of-concept (POC) Information        top

12.2 - Description        top

Note:

This generator can be used from within Visual Basic Express 2005 Beta. See related article.

   
   

This POC reproduces the VisualBasic.NET (VB.NET) code produced by Kathleen Dollard's generator in her article "Generate .NET Code With XSLT", published on VisualStudio Magazine.

The generator of this POC produces VB.NET classes that provide strongly typed access based on a database's XML Schema Definition. A thorough description of the generator's input and of the generated code is provided in "Generate .NET Code With XSLT".

Kathleen's generator is based on Extensible Stylesheet Transformations (XSLT), while this POC generator exploits Tefigel's XML processing and file generation capabilities.

In particular, this refactored version of the generator also exploits new Tefigel constructs, that allowed to significantly simplify the generator structure in comparison with the generator of the previous paragraph .

Purpose of this POC is to demonstrate portability of code generation across different code generators, realized with different techniques: the same input model processed by different generators produces the same code. Another purpose of this POC is to demonstrate the adaptability of the Somusar/Code Generator Building[sm] service: the POC generator reproduces the same coding style (indenting, naming convention for the identifiers) of Kathleen's code.

The XML input file used in the POC is the same as the "Simplified XML document describing schema" from Kathleen's article and is linked to from the following table.
