Detailed Description

C++ API: Regular Expressions.

The ICU API for processing regular expressions consists of two classes, `RegexPattern` and `RegexMatcher`. `RegexPattern` objects represent a pre-processed, or compiled regular expression. They are created from a regular expression pattern string, and can be used to create `RegexMatcher` objects for the pattern.

Class `RegexMatcher` bundles together a regular expression pattern and a target string to which the search pattern will be applied. `RegexMatcher` includes API for doing plain find or search operations, for search and replace operations, and for obtaining detailed information about bounds of a match.

Note that by constructing `RegexMatcher` objects directly from regular expression pattern strings application code can be simplified and the explicit need for `RegexPattern` objects can usually be eliminated.
