TabType

An enumeration of all the tab types.

To call an enum, you call its parent class, name, and property. For example, `
DocumentApp.TabType.TAB`.

Use the `TabType` enumeration to check the type of a given element, for instance:

```javascript
const tab = DocumentApp.getActiveDocument().getActiveTab();
// Use getType() to determine the tab's type before casting.
if (tab.getType() === DocumentApp.TabType.DOCUMENT_TAB) {
  // It's a document tab, write some text to it.
  tab.asDocumentTab().setText('Hello World!');
} else {
  // There are currently no types other than DOCUMENT_TAB.
}
```
