 org.apache.oro.text.regex.Perl5Debug
| Perl5Debug | | final public class Perl5Debug (Code) | | The Perl5Debug class is not intended for general use and should not
be instantiated, but is provided because some users may find the output
of its single method to be useful.
The Perl5Compiler class generates a representation of a
regular expression identical to that of Perl5 in the abstract, but
not in terms of actual data structures. The Perl5Debug class allows
the bytecode program contained by a Perl5Pattern to be printed out for
comparison with the program generated by Perl5 with the -r option.

| Method Summary | |
| static void | _printOperator(char[] program, int offset, StringBuffer buffer)
| | public static String | printProgram(Perl5Pattern regexp)
This method prints to a String the bytecode program contained in a
Perl5Pattern._ The program byte codes are identical to those
generated by Perl5 with the -r option, but the offsets are
different due to the different data structures used. |
| _printOperator | | static void _printOperator(char[] program, int offset, StringBuffer buffer)(Code) | | |
| printProgram | | public static String printProgram(Perl5Pattern regexp)(Code) | | This method prints to a String the bytecode program contained in a
Perl5Pattern._ The program byte codes are identical to those
generated by Perl5 with the -r option, but the offsets are
different due to the different data structures used. This
method is useful for diagnosing suspected bugs. The Perl5Compiler
class is designed to produce regular expression programs identical
to those produced by Perl5. By comparing the output of this method
and the output of Perl5 with the -r option on the same regular
expression, you can determine if Perl5Compiler correctly compiled
an expression.
Parameters:
regexp - The Perl5Pattern to print. A string representation of the bytecode program defining theregular expression. |
