Re: [rules-users] Custom operator
Hello,
It seems that the logic behind the "operator" drop-down list comes from
the
"org.drools.ide.common.client.modeldriven.SuggestionCompletionEngine"
and "org.drools.eclipse.rulebuilder.modeldriven.HumanReadable" classes.
That's for the "rule authoring" perspective.
I've also seen that the business rule editor involves the DrlParser
class. So, in a "rule parsing" perspective, I guess I need to find a way
to register my custom operator into the EvaluatorRegistry used by the
Eclipse plugin (and I don't know where this can be done).
Do you think I am on the right track? Is there a risk that code
modifications will involve so many classes that, in the end, adding a
custom operator to the business rule editor will be a difficult task for
someone very new to Drools (like me)?
Thanks in advance,
Best regards,
Bruno.

Hello,
I'd like to implement a custom "lucenematches" operator that would
enable writing conditions like:
$d : Doc(text lucenematches "(foo AND bar) OR roam~0.8")
As I've taken a look at the following post on athico
(http://blog.athico.com/2009/05/imperfect-evaluations.html), and seen
that the appendix B of the "Drools JBoss Rules 5.0 Developer's Guide"
book that deals with custom operators, I am rather confident that I will
find my way in implementing my operator (if not, I'll post here again :-)).
However, I wonder if it will be possible to add my "lucenematches"
operator to the "operator" drop-down list of the Eclipse's Business Rule
Editor.
Does anyone have an idea?
Best regards,
Bruno.
