public class Range
extends java.lang.Object

This class is the central class of the HWPF object model. All properties that apply to a range of characters in a Word document extend this class. It is possible to insert text and/or properties at the beginning or end of a range. Ranges are only valid if there hasn't been an insert in a prior Range since the Range's creation. Once an element (text, paragraph, etc.) has been inserted into a Range, subsequent Ranges become unstable.
