[news.eclipse.technology.gmt] Re: [MOFScript] Many metamodels as input

[Sven Efftinge <sven@xxxxxxxxxxx>]

With oAW it is possible (and straight forward) to use multiple models 
based on multiple metamodels (which themself could be made of different 
meta metamodels).
Here is an example workflow:

<workflow>
<component class="oaw.emf.XmiReader">
  <metaModelFile value="metamodel1.ecore"/>
  <modelFile value="mymodel.metamodel1"/>
<!-- storing the first model in the slot 'model1' -->
  <outputSlot value="model1"/>
  <firstElementOnly value="true"/>
</component>
<component class="oaw.emf.XmiReader">
  <metaModelFile value="metamodel2.ecore"/>
  <modelFile value="mymodel.metamodel2"/>
<!-- storing the second model in the slot 'model2' -->
  <outputSlot value="model2"/>
  <firstElementOnly value="true"/>
</component>
<component class="oaw.xpand2.Generator">
  <metaModel class="oaw.type.emf.EmfMetaModel" 
metaModelFile="metamodel1.ecore"/>
  <metaModel class="oaw.type.emf.EmfMetaModel" 
metaModelFile="metamodel2.ecore"/>
  <!-- model1 is passed as an additional parameter -->
  <expand value="templates::Root::root(model1) FOR model2"/>
  <genPath value="main/src-gen/"/>
</component>
</workflow>

The Template file "template/Root.xpt" could look like this:


<<IMPORT metamodel1>>
<<IMPORT metamodel2>>

<<DEFINE root(RootNode1 rt) FOR RootNode2>>
  do stuff
<<ENDDEFINE>>

Sven
