I need to test if a tag is a folder :

```auto
TagPath tagPath = TagPathParser.parseSafe("default",fullTagPath);
```

According to SDK javadoc,  
com.inductiveautomation.ignition.common.sqltags.model, Interface TagPath,

`isFolder()` is Deprecated.,

```auto
TagProp getProperty()
```

Returns the type of property in the tag that this path is referencing. If this path represents a folder, this will be null. If the path points just to a tag, this will return TagProp.Value (the default property)

But with a tag folder path, `tagPath.getProperty()` doesn’t return null (client and designer scope).  
I missed something or there is another way to test if a TagPath is a folder or not 🤔

The Javadoc on `TagPath#isFolder()` says that you must now get the actual item/tag pointed to by the path and check its type.

`Tag#getType()` returns a `TagType` enum, and you can check to see if it’s `TagType.Folder`.

Yes, but how can I obtain a Tag object from a TagPath object ?

Depends on the scope you’re in I guess. In the Gateway the `TagManager` from `GatewayContext#getTagManager()` has `getTag(TagPath)` on it.

I’m in the client scope, client context provide getTagManager too. Thanks a lot for your help 👍

</div>

with **Ignition 8.1** getTag doesn’t exist anymore.  
Is there another way to determine if a TagPath is a Folder ?

You would read the `NodeDescription` property and then check the `TagObjectType` returned by `NodeDescription::getObjectType`.

Only `browseAsync` seems to return NodeDescription, is there another way to read `NodeDescription` ?

Yeah, read it with `readAsync`. Append the NodeDescription property to your original TagPath:

```auto
val descriptionPath: TagPath = tagPath.getChildPath(RuntimeTagProps.NodeDescription)

```
