I followed the migration guide from http://www.eclipse.org/Xtext/documentation.html#migrating_from_1_0_x but i Could not find the alternative for the following methods in Xtext 2.3 which were present in Xtext1.0

1. NodeUtil.getNearestSemanticObject(AbstractNode node)
2. ParseTreeUtil.getLastCompleteNodeByOffset(CompositeNode node ,int offset);
3. NodeAdapter.getNodeAdapter(EObject obj);
4. NodeUtil.findASTElement(CompositeNode root);
5. NodeUtil.getRootNode(EObject obj);

Any Help will be much appreciated.

Hi in NodemodelUtils (findactualsemanticobjectfor) and inode
(getrootnode) may be some of the things you are looking for (have a
look at the java docs)

You will find replacements for everything. There is stuff that is
obsolete like getnodeadapter since the node model technically changed

Thanks Christian for your response.
I have one more doubt, There was a class in Xtext 1 as org.eclipse.xtext.MweReader which was deprecated, URIBasedReader is to be used as an alternative if i am not wrong, but i could not find an appropriate method equivalent to doValidate.

Hi as far as I remember the new class is simply called Reader

Hi,

I was successful in migrating all parts except the Editor Validations. As suggested i tried using error(String, EStructuralFeature) instead of error(String, Integer), but then i get the following error :
ERROR org.eclipse.xtext.validation.CompositeEValidator - Error executing EValidator
java.lang.IllegalArgumentException: The sources EClass 'ABC' does not expose the feature 'DEF'.

I am using it like
@Check(CheckType.FAST)
public void checkValue(final ABC abc) {
//some logiv....
error("Value does not match",Epackage.Literal.DEF);
}

Id expect something like my pack.literals.ABC__Name
Or pack.literals.ABC__somethingelse

Can you tell why you use DEF
