Class recompile


public class recompile
extends java.lang.Object

'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,

    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);
