Range (GWT Elemental 2.7.0)

All Known Implementing Classes:

JsRange
```
public interface Range
```
The Range object represents a fragment of a document that can contain nodes and parts of text nodes in a given document.

A range can be created using the Document.createRange method of the Document object. Range objects can also be retrieved by using the Selection.getRangeAt method of the Selection object.
