### Text Overview

The classes that are part of the Open Class Text Framework enable the creation, storage, querying ,and modification of text strings.

The primary classes provided by the Text Framework are:

- IText, a variable-length styled string class you can use for storing styled or unstyled international text. The IText class is optimized for text of any length, from short strings to large text data segments. The length of an IText string is limited chiefly by hardware and operating system constraints (the theoretical limit is four billion characters). For ease of use and consistency, IText stores style data along with character data so that you can use styled characters throughout the Open Class environment.
- ITextBoundary, which implements methods for locating boundaries of characters, words, lines, and sentences.
- IString, which can be useful when you do not require the style and international text capabilities provided by IText.
- Style classes, which can be applied to individual characters, ranges of characters, or paragraphs.
- Iterator classes, which provide access to the character data in IText objects.
