| 'recompile' is a command line tool that pre-compiles one or more regular expressions
for use with the regular expression matcher class 'RE'. For example, the command
"java recompile a*b" produces output like this:
// Pre-compiled regular expression "a*b"
char[] re1Instructions =
{
0x007c, 0x0000, 0x001a, 0x007c, 0x0000, 0x000d, 0x0041,
0x0001, 0x0004, 0x0061, 0x007c, 0x0000, 0x0003, 0x0047,
0x0000, 0xfff6, 0x007c, 0x0000, 0x0003, 0x004e, 0x0000,
0x0003, 0x0041, 0x0001, 0x0004, 0x0062, 0x0045, 0x0000,
0x0000,
};
REProgram re1 = new REProgram(re1Instructions);
By pasting this output into your code, you can construct a regular expression matcher
(RE) object directly from the pre-compiled data (the character array re1), thus avoiding
the overhead of compiling the expression at runtime. For example:
RE r = new RE(re1);
