Classes:

• AwkCompiler: The AwkCompiler class is used to create compiled regular expressions conforming to the Awk regular expression syntax. It generates AwkPattern instances upon compilation to be used in conjunction with an AwkMatcher instance. AwkMatcher finds true leftmost-longest matches, so you must take care with how you formulate your regular expression to avoid matching more than you really want. The supported regular expression syntax is a superset of traditional AWK, but NOT to be confused with GNU AWK or other AWK variants. Additionally, this AWK implementation is DFA-based and only supports 8-bit ASCII. ...
• AwkStreamInput: The AwkStreamInput class is used to look for pattern matches in an input stream (actually a java.io.Reader instance) in conjunction with the AwkMatcher class. It is called AwkStreamInput instead of AwkInputStream to stress that it is a form of streamed input for the AwkMatcher class to use rather than a subclass of InputStream. AwkStreamInput performs special internal buffering to accelerate pattern searches through a stream. You can determine the size of this buffer and how it grows by using the appropriate constructor. If you want to perform line by line matches on an input stream, you should ...
• AwkPattern: An implementation of the Pattern interface for Awk regular expressions. This class is compatible with the AwkCompiler and AwkMatcher classes. When an AwkCompiler instance compiles a regular expression pattern, it produces an AwkPattern instance containing internal data structures used by AwkMatcher to perform pattern matches. This class cannot be subclassed and cannot be directly instantiated by the programmer as it would not make sense. It is however serializable so that pre-compiled patterns may be saved to disk and re-read at a later time. AwkPattern instances should only be created through ...
• AwkMatcher: The AwkMatcher class is used to match regular expressions (conforming to the Awk regular expression syntax) generated by AwkCompiler. AwkMatcher only supports 8-bit ASCII. Any attempt to match Unicode values greater than 255 will result in undefined behavior. AwkMatcher finds true leftmost-longest matches, so you must take care with how you formulate your regular expression to avoid matching more than you really want. It is important for you to remember that AwkMatcher does not save parenthesized sub-group information. Therefore the number of groups saved in a MatchResult produced by AwkMatcher ...
• AwkMatchResult: A class used to store and access the results of an AwkPattern match. It is important for you to remember that AwkMatcher does not save parenthesized sub-group information. Therefore the number of groups saved in an AwkMatchResult will always be 1.
