find out if an outlining node has an end token?

I believe there is an IsOpen property, where also the EndOffset is -1.

Hi,

Thanks for the reply.

In my case I'm not seeing this behaviour. The IsOpen property is set to true and the EndOffset has a postive integer value.

It is matching something there then. Try looking at the token at that offset.

Hi,

Thanks for the reply.

There's a line terminator at the indicated offset.

I'll give you some steps to follow so you can mimic what I'm doing. I haven't done a good job of explaining myself so far but hopefully this will help.

In the sample application:

1. Open up SDI Editor Application and change the language to SQL.
2. Select and delete the pre-loaded SQL example and hit return a few times so you have a few lines in the document.
3. Place the cursor on line 1 and type "--region" (without the quotes).

Upon typing the "n" in "region" you'll notice that an outlining node is created where the end of that outlining node is on the last but second line in the document. So if you have 5 lines in the document the end offset of the outlining node is on line 4. This is despite the fact that this particular outlining node needs "--end region" in order to close it.

Now, if you add a watch for editor.Document.Outlining.RootNode.FindNodeRecursive(0) you'll notice that the endoffset isn't -1.

Essentially I want to check whether a given outlining node has it's ending properly defined (in the above example this would be "--end region"). However, I cannot just check whether the token at the endoffset is "--end region" because it is possible that another node just happens to end in exactly the same place.

The question is, am I doing something wrong here? Or is there another way I should be doing this in order to achieve the desired result?

Thanks,

Karl

My apologies, the EndOffset will always return an offset even if there is no match. In the case where the node is a child node and has no end, it will return the end offset of the parent. In the case where the node is a root node and has no end, it will return the document length.

The way to tell if a node has an end is via the IsOpen property by itself. So if IsOpen = true then you know the EndOffset is really a "virtual" offset and doesn't indicate a token ends the node. Rather a parent node or the document end ends it.

I hope that makes sense. IsOpen will be false for all outlining nodes that have a proper end token.

Thanks a lot for the clarification. That's perfect!

I had incorrectly assumed that IsOpen referred to whether the node was collapsed or not and I never noticed that it was set to false when the node had an end.

Thanks again,

Karl

Right, an "open" node is considered to be a node that has no end. The Expanded property will tell you whether the node is expanded or collapsed.
