[news.eclipse.modeling.gmt.amw] Re: [ATL] KM3 metamodel extension

[Marcos Didonet Del Fabro <marcos.didonet-del-fabro@xxxxxxxxxxxxxx>]

Hello,

You can use the generic editor, as if you were creating a complete KM3 
metamodel. However, the editor will indicate syntax errors, since it 
cannot refer to the extended elements.

We have a typical case of metamodel extension when using the AMW 
plug-in. We define an extension like that:

class Attribute extends WLinkEnd {
}

The WLinkEnd class is defined in a core weaving metamodel. In this 
particular case, it is not necessary to set up any path, because the 
core metamodel is extended automatically when using the AMW tool.

Regards,

Marcos.
