Use Class Hierarchy or Alphabetical List * or Compound List * to find the class you are interested in. For example, to find BreakIterator, * you can go to the Alphabetical List, then click on * "BreakIterator". Once you are at the class, you will find an inheritance * chart, a list of the public members, a detailed description of the class, * then detailed member descriptions.
* *Use Module List or File Members * to find a list of all the functions and constants. * For example, to find BreakIterator functions you would click on * File List, * then find "ubrk.h" and click on it. You will find descriptions of Defines, * Typedefs, Enumerations, and Functions, with detailed descriptions below. * If you want to find a specific function, such as ubrk_next(), then click * first on File Members, then use your browser * Find dialog to search for "ubrk_next()".
* * *The API References for each release of ICU are also available as * a zip file from the ICU * download page.
