Re: [xmlvm-users] Proper method for including native code

[Arno P. <ar...@pu...>]

those comment markers are always emitted but only used for skeleton 
classes. For skeleton classes, XMLVM will inject the implementation 
between those comment markers into the generated code. This is meant as 
an internal mechanism and shouldn't be used by a developer.

You can mark methods as 'native'. In those cases XMLVM will not emit an 
implementation and you can link a separate file to your executable that 
provides the implementation of the native methods. In this case you have 
to comply to XMLVM's name mangling and passing of parameters. As a first 
step, add a static native method to a class and compile this with XMLVM. 
The linker's unresolved external error will guide you what to do.
