URL: http://jira.jboss.com/jira/browse/JBRULES-1430
Project: JBoss Drools
Issue Type: Feature Request
Security Level: Public (Everyone can see)
Components: All
Affects Versions: 4.0.4
Environment: all
Reporter: longDuck dong
Priority: Minor
The current design of the Function is a bit limiting. for example, if I want to write a
function to insert, update or retract facts, the current design does not support it.
According to the docs
http://downloads.jboss.com/drools/docs/4.0.4.17825.GA/html/ch06s04.html, functions are
just helper methods. It would be more powerful if the function always passes the
workingmemory to the function. This way, the functions can easily access the globals or
access the rule engine. Basically, something similar to JESS funcall
http://herzberg.ca.sandia.gov/docs/70/api/jess/Funcall.html.
It also makes it easier for developers to encapsulate common actions in the consequence in
a function and use it easily from a DSL. The pattern is well proven in CLIPS, JESS and
haley.

-------------------------------------
How would one do that from a rule, if "workingmemory" is not a reserved word in
DRL language?
http://downloads.jboss.com/drools/docs/4.0.4.17825.GA/html_single/index.h...
Would it be better for the engine to automatically pass that and have it part of the
Function interface, so that "workingmemory" doesn't have to be a reserved
word and change the parser? It's common in machine learning applications to have a
Meta rule that creates new rules. To do this in clips and JESS is trivial.
I suppose one could statically pass the workingmemory object to the functions, but that
feels a bit hack-ish.

-------------------------------------
A comment on passing the workingmemory statically to the functions. That approach
wouldn't work if a single JVM has multiple instances of Reteoo or workingmemories. It
would only work if there's only 1 Reteoo and workingmemory in the JVM.
having it part of the function interface and having the engine automatically pass
workingmemory as a parameter would be much cleaner and safer.

---------------------------------------
If you can provide a patch we'll consider it. However this requires text mangling,
which is hard to do and as users can just pass the workingmemory themselves it's low
on our priority.
By this I mean in the consequence how do you detect a function call and how do you mangle
the text to insert the workingmemory parameter at the end. This isn't something that
can be done simply with some regular expression.

Mark Proctor commented on JBRULES-1430:
---------------------------------------
Just as a reminder there is no function interface, it's just a static method call.
But you can do something like this:
function void addRule(String pkgName, String rule, RuleBase ruleBase ) {
PackageBuilder builder = new PackageBuilder();
builder.addPackgeFromDrl( new StringReader( rule ) );
ruleBase.addPackage ( builder.addPackage() );
}
rule X
when
then
String rule = "package org.drools.test\n global java.util.List list\n rule xxx\n
when\n i:Integer()\nthen\n list.add(i);\nend";
addRule( "org.domain", rule, drools.getWorkingMemory().getRuleBase() );
end
There is nothing stopping you passing drools.getWorkingMemory() and
drools.getWorkingMemory().getRuleBase() as parameters.
The extra work needed, as described above, just to achieve this isn't trivial. But we
will consider any robust patches you have.
