Package org.apache.regexp
Class recompile
java.lang.Object
org.apache.regexp.recompile
'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 org.apache.regexp.recompile re1 "a*b"
produces output like this:
// Pre-compiled regular expression 'a*b' private static final char[] re1Instructions = { 0x002a, 0x0000, 0x0007, 0x0041, 0x0001, 0xfffd, 0x0061, 0x0041, 0x0001, 0x0004, 0x0062, 0x0045, 0x0000, 0x0000, }; private static final 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);
