Inherits from UITextRange
Conforms to NSCopying
Declared in DTTextRange.h

Overview

This class represents a range of text in an DTRichTextEditorView. It is a concrete subclass of UITextRange.

A range is considered empty if start is equal to end because the length generally does not include the ending character, similar to a caret being position on the index of the ending character.
