CodeDom

From The Oxygene Language Wiki

This is a Platform topic
Feel free to add your notes to this topic below.

The .NET framework includes a set of classes in the CodeDOM namespace, called the Code Document Object Model. These classes make it possible to generate source code for .NET languages without knowing the target language beforehand.

There are several providers included with .NET: CSharp, VB.NET and Javascript. Delphi Prism comes with its own CodeDom provider.

Another feature of the provider is to compile the input provided in the document model to a compiled assembly, either directly to memory as a dynamically loaded and generated assembly, or as an executable. ASP.NET uses this mechanism to compile the ASPX pages on demand when the user first requests them.

CodeDom is limited in the constructs that are supported and extended language features like foreach loops or language specific options are not allowed.

CodeDom also features a Code Parser, which is used by the WinForms designer to read back the generated code to a form. The CodeParser class is fairly limited in that it can only support the features exposed by the CodeDom namespace; other constructs are unsupported.
