=head1 SYNOPSIS
=for comment
import org.perl.inline.java.* ;
class HelpMePerl {
static private InlineJavaPerlInterpreter pi = null ;
public HelpMePerl() throws InlineJavaException {
}
static private boolean matches(String target, String pattern)
throws InlineJavaPerlException, InlineJavaException {
Boolean b = (Boolean)pi.eval("'" + target + "' =~ /" + pattern + "/", Boolean.class) ;
return b.booleanValue() ;
}
public static void main(String args[])
throws InlineJavaPerlException, InlineJavaException {
pi = InlineJavaPerlInterpreter.create() ;
String target = "aaabbbccc" ;
String pattern = "ab+" ;
boolean ret = matches(target, pattern) ;
System.out.println(

=head1 DESCRIPTION
WARNING: C<Inline::Java::PerlInterpreter> is still experimental.
The C<org.perl.inline.java.InlineJavaPerlInterpreter> Java class allows
you to load a Perl interpreter directly from Java. You can then perform
regular callbacks to call into Perl.
Z<>
=head1 USING THE org.perl.inline.java.InlineJavaPerlInterpreter CLASS
B<Installation>
Before using C<org.perl.inline.java.InlineJavaPerlInterpreter>, you must
have installed C<Inline::Java> as well as the JNI extension. Additionally,
the PerlInterpreter extension must also have been installed.
B<Finding the jar>
To be able to use the C<org.perl.inline.java.InlineJavaPerlInterpreter>
class, you must use the jar file provided by C<Inline::Java>. You can
easily locate this jar file using the following command:
% perl -MInline::Java=jar
You must then add this jar file to your CLASSPATH as you would any jar
file.
B<Basic Usage>
C<org.perl.inline.java.InlineJavaPerlInterpreter> itself extends
C<org.perl.inline.java.InlineJavaPerlCaller>. See L<Inline::Java::Callback>
for information on the callback API.
Besides that API, C<org.perl.inline.java.InlineJavaPerlInterpreter> provides
only 2 other public methods:
=over 4
=item public InlineJavaPerlInterpreter create()
throws InlineJavaPerlException, InlineJavaException
Creates a new org.perl.inline.java.InlineJavaPerlInterpreter object.
This class in a singleton.
=item public void destroy()
Destroys the Perl interpreter.
