Interface | Description |
---|---|
MatchResult |
The MatchResult interface allows PatternMatcher implementors to return
results storing match information in whatever format they like, while
presenting a consistent way of accessing that information.
|
Pattern |
The Pattern interface allows multiple representations of a regular
expression to be defined.
|
PatternCompiler |
The PatternCompiler interface defines the operations a regular
expression compiler must implement.
|
PatternMatcher |
The PatternMatcher interface defines the operations a regular
expression matcher must implement.
|
Substitution |
The Substitution interface provides a means for you to control how
a substitution is performed when using the
Util.substitute method. |
Class | Description |
---|---|
PatternMatcherInput |
The PatternMatcherInput class is used to preserve state across
calls to the
contains() methods of PatternMatcher instances. |
Perl5Compiler |
The Perl5Compiler class is used to create compiled regular expressions
conforming to the Perl5 regular expression syntax.
|
Perl5Debug |
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.
|
Perl5Matcher |
The Perl5Matcher class is used to match regular expressions
(conforming to the Perl5 regular expression syntax) generated by
Perl5Compiler.
|
Perl5Pattern |
An implementation of the Pattern interface for Perl5 regular expressions.
|
Perl5Substitution |
Perl5Substitution implements a Substitution consisting of a
literal string, but allowing Perl5 variable interpolation referencing
saved groups in a match.
|
StringSubstitution |
StringSubstitution implements a Substitution consisting of a simple
literal string.
|
Util |
The Util class is a holder for useful static utility methods that can
be generically applied to Pattern and PatternMatcher instances.
|
Exception | Description |
---|---|
MalformedPatternException |
A class used to signify the occurrence of a syntax error in a
regular expression that is being compiled.

Note: The following information will be moved into the user's guide.
Here we summarize the syntax of Perl5.003 regular expressions, all of
which is supported by the Perl5 classes in this package. However, for
a definitive reference, you should consult the
perlre
man page
that accompanies the Perl5 distribution and also the book
Programming Perl, 2nd Edition from O'Reilly & Associates.
We are working toward implementing the features added after Perl5.003
up to and including Perl 5.6. Please remember, we only guarantee
support for Perl5.003 expressions in version 2.0.
By default, a quantified subpattern is greedy . In other words it matches as many times as possible without causing the rest of the pattern not to match. To change the quantifiers to match the minimum number of times possible, without causing the rest of the pattern not to match, you may use a "?" right after the quantifier.
Perl5 extended regular expressions are fully supported.
