C++ API: Regular Expressions.
The ICU API for processing regular expressions consists of two classes,
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.
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.
