A "builder"-style helper class for manipulating character classes represented as an array of pairs of runes [lo, hi], each denoting an inclusive inter

Wraps Character methods to be overridden for GWT.

GWT supersource for {@link Character#toLowerCase}.

Compiler from {@code Regexp} (RE2 abstract syntax) to {@code RE2} (compiled regular expression). The only entry point is {@link #compileRegexp}.

A fragment of a compiled regular expression program. @see http://swtch.com/~rsc/regexp/regexp1.html

This class exercises the GWT compiler against a small RE2J test GWT module. The purpose of the test is to break when GWT-incompatible changes are made

A single instruction in the regular expression virtual machine. @see http://swtch.com/~rsc/regexp/regexp2.html

MachineInput abstracts different representations of the input text supplied to the Machine. It provides one-character lookahead.

A stateful iterator that interprets a regex {@code Pattern} on a specific input. Its interface mimics the JDK 1.4.2 {@code java.util.regex.Matcher}.

Abstract the representations of input text supplied to Matcher.

A parser of regular expression patterns. The only public entry point is {@link #parse(String pattern, int flags)}.

An exception thrown by the parser if the pattern was invalid. Following {@code java.util.regex.PatternSyntaxException}, this is an unchecked exceptio

This class checks that the behaviour of Pattern and JDK's Pattern are same, and we expect them that way too. @author afrozm@google.com (Afroz Mohiudd

A Prog is a compiled regular expression program.

An RE2 class instance is a compiled representation of an RE2 regular expression, independent of the public Java-like Pattern/Matcher API. <p> This cl

Tests of RE2 API.

Regular expression abstract syntax tree. Produced by parser, used by compiler. NB, this corresponds to {@code syntax.regexp} in the Go implementation;

A simple reader of lines from a UNIX character stream, like java.io.BufferedReader, but doesn't consider '\r' a line terminator. @author adonovan@goo

Utilities for dealing with Unicode better than Java does. @author adonovan@google.com (Alan Donovan)

Generates Unicode data tables for RE2J. The output of this program should be written to {@code UnicodeTables.java}. Code is google-java-formatted befo
