Migration Guide

Acceleo 2.x to 3.x equivalences

Miscellaneous

Acceleo 2 Expression Acceleo 3 Expression (OCL)
<%metamodel http://www.eclipse.org/uml2/2.0.0/UML%> [module module_name('http://www.eclipse.org/uml2/2.0.0/UML')/]
<%import module.mt%> [import module/] or [import org::eclipse::acceleo::mypackage::module/]
<%import service.java%> Services no longer need to be imported
<%list + object%> [list->including(object)/]
<%list1 + list2%> [list1->union(list2)/]
<%string + object%> [string + object/]
<%list - object%> [list->excluding(object)/]
<%list1 - list2%> [list1->asSet() - list2->asSet()/] (Note that this no longer keeps duplicates, which is not strictly equivalent to Acceleo 2)
<%list1 \p\p list2%> [list1->union(list2)/]
<%list && object%> element = object)/]
<%list1 && list2%> [list1->iterate(element; result : Sequence(T) = Sequence{} if list2->includes(element) then result->including(element) else result endif)/]
<%list1 == list2%> [list1 = list2/]
<%list1 != list2%> [list1 <> list2/]
<%object != object%> [object <> object/]
<%! boolean%> [not boolean/]

EObject Services

Acceleo 2 Expression Acceleo 3 Expression (OCL)
<%x.eAllContents%> [x.eAllContents()/]
<%x.eAllContents("EClass")%> [x.eAllContents(EClass)/]
<%x.eClass%> [x.eClass()/]

<%x.eResourceName%>
<%x.getRootContainer%> [x.ancestors()->last()/]
<%load("//UML2_LIBRARIES/UML2PrimitiveTypes.library.uml2")%> No direct equivalent : Acceleo 3 accepts more than one model element as arguments of a generation. An alternative would be to use a custom Java service for this need.
