Hi ,


I have a source MetaModel in ecore & target metaModel in ecore.

In my source Metomodel i have a Eclass LDMCoreview & it has 2 Esupertypes
LDMEntityWithAliases & LDMCoreEntityViewBase

In My target metamodle I have a Eclass LdapCoreVariantObjectClass and it
has 2 Esupertypes LdapObjectClassWithAliases & PDMCoreEntityViewBase

I created rule for

rule LDMCoreEntityViewBase_2_PDMCoreEntityViewBase {
from
v_left : LdmMetaModel!LDMCoreEntityViewBase
to
v_right : PdmModel!PDMCoreEntityViewBase (
childEntities <-
Set {v_left.childEntities},
childViews <-
Set {v_left.childViews}
)
}

rule LDMEntityWithAliases_2_LdapObjectClassWithAliases{
from
v_left : LdmMetaModel!LDMEntityWithAliases
to
v_right : PdmModel!LdapObjectClassWithAliases (
childAliases <-
Set {v_left.childAliases}
)
}
rule LDMCoreView_2_LdapCoreVariantObjectClass{
from
v_left : LdmMetaModel!LDMCoreView
to
v_right : PdmModel!LdapCoreVariantObjectClass(
viewAttributes <-
Set {v_left.viewAttributes},
viewNamings <-
Set {v_left.viewNamings}
)
}


If i have one Esuper Type then i can use extend (for example rule A extend
rule B) .Here i have morethan one Esupertype i don't know how to extend
morethan one Esuper type

LDM.ecore(Source Metomodel)

<eClassifiers xsi:type="ecore:EClass" name="LDMEntityWithAliases"

Venkatesh,

I can give you a definitive answer, but I've just checked the
ATL grammar and this only allows a match rule to extend
one other rule.
