How to reference Parameter.ZERO with Ruby Builder?

[Michael Rimov]

Hi All,

I've never really played with the Ruby language or builder, but since
I've had compilation performance problems with Groovy, I've been
writing a scripting language comparison test case to get an idea of
where all the different builders stood with each other
performance-wise.

However, I've been unable to figure out how to reference
Pararameter.ZERO from Ruby. Currently my test case looks like this:
@Test
public void testParameterZero() {
Reader script = new StringReader("" +
"import org.picocontainer.Parametern" +
"n" +
"container{n" +
" component(:class => java.util.ArrayList,
:parameters => Parameter::ZERO)n" +
" component(:class => java.util.HashSet,
:parameters => Parameter::ZERO)n" +
"}n"
);
PicoContainer pico = buildContainer(script, null,
ASSEMBLY_SCOPE);
assertNotNull(pico.getComponent(ArrayList.class));

assertNotNull(pico.getComponent(HashSet.class));
}
However, I get a CyclicDependencyException much as if I hadn't
specified Parameter.ZERO in the first place. Any clues?

Thanks :)

Well the Ruby capability is not as advanced as the Groovy one. Dave
Astels has me on a promise to do some pairing one lunch time to work
through it and make it more idiomatically correct. How's your Ruby
Mike ?

If you're running the same builder script over and over, the JRuby one
should me progressively more preferment.
