Getting hidden tokens for a model element [message #1287123]

Hello guys,
my grammar defines different hidden nodes per model element. Since it is not handled well by the serializer I need to map from model element to hidden nodes defined for it. I'm sure there's an API for this - just wasn't able to find it. Any help?

Cheers,
Paweł

And simply for accessing the node model reading wise: NodeModelUtil

and maybe (if you talk about the grammar) org.eclipse.xtext.ParserRule.getHiddenTokens()

Christian,
I meant my grammar redefines hidden nodes in a few places so WS is not always considered hidden. The Seriazlier I'm using doesn't take this into account though. So I was looking for something like ParserRule.getHiddenTokens() to hack the Serializer but this method always returns an empty list.

I'm using Xtext 2.3.1 and looks like there were some changes in this area in subsequent releases. So I'll browse more code, thanks for the pointers.

Thanks,
Pawel

I'm using the new Serializer but have customized it.

Anyways, just found the problem with ParserRule.getHiddenTokens(), now it works fine. Thanks Christian, that was exactly what I was looking for.
