Re: [rules-users] Drools - is dynamic change possible ?

2007-08-17 Thread pns77 

Hi,

The following is the block of code that i tried

RuleBase ruleBase = readRule();
WorkingMemory workingMemory =
ruleBase.newStatefulSession(false); // to keep reference
// Create a message object
workingMemory.insert( message );
workingMemory.fireAllRules();

When i try chaning the drl file at run time the change doesnt get
reflected. Is there anything else i need to be doing here?  Any additional
jar files ?

To have this change take effect at runtime - do i need to create a new
session for each run or do i need to retain the session - i tried both
newStatefulSession(false) and newStatefulSession() - get the same result
with both.

 Yes this can be done at runtime. The RuleBase has a reference to each of 
 the created StatefulSessions that has not called dispose() yet and will 
 push those rule changes out to each running session.

 Thanks for the response.

 Just to confirm when you say ...but you can remove a rule and add
 another
 in its place... - can this be done at runtime - i.e server is running, i
 go
 add a new rule/change the output of an existing rule. If so, can  i have
 the
 new rule take effect ?

 Also, do i need to include any specific jar file for this dynamic feature
 ?

 Am not looking at performance here - more from a
 maintenance/changeability
 point of view.

 System.out.println( message );

Re: [rules-users] programmatic manipulation of 4.0 salience?

2007-08-17 Thread Yuri de Wit 
Scott,

not sure if it fits your problem, but you may also consider using
dynamic saliences. Yesterday I was able to convert 3.x rules to use it
worked very well.

In my case, I have facts of different sizes (some are collections of
other facts, some are individual facts) and in some rules I need to
find first MxN pairs (collection facts on both sides), then Mx1 or 1xN
pairs, and only then 1x1 pairs. In other rules I need to find first
1x1 pairs, then Mx1 or 1xN pairs and only then MxN.

Instead of writting a custom ConflictResolver, what I did was to use
one dynamic salience:

salience (1000 / (c.size * t.size))

for finding smallest pairs first, and

salience (-1000 / (c.size * t.size)

for finding the largest pairs first.

The 1000 is to get around the fact that saliences are integers and not
float/double (afaik)

Hope it helps,

I guess I could add my own salience field to all my working memory objects, but it seems like 
overkill when I don't want to change the salience during a run. I just want to be able to set it as 
a constant salience before the rules are loaded and run.

You should also use the parentheses for functions, as in normal Java code:

eval ( teste() )

Of course you can add parameters etc. to your functions like this as well.

Actually that is incomplete, it should have been disabled.

The current audit view only shows data at the end when you call write(). 
The realtime audit view streams data so you can look at the execution 
flow in the audit view at debug time, i.e. mid execution.

2007-08-17 Thread Scott Reed 

For lack of any better suggestion I am getting the int salience using
Integer.parse(rule.getPriority().toString()).
Of course this is a huge hack since it depends on the undocumented toString() function returning the 
string value of the integer salience.


I am still very interested to hear how the designers thought we should use the API to get the 
salience value.

[rules-users] Re: Drools 4.0 problem: insert (drl) not reflected StatefulSession.

2007-08-17 Thread Michael Waluk 
I found my problem, in case anyone else has this same issue (until
4.0.1which may have this fixed):

The ClassObjectFilter's accept method works like this:

public boolean accept(Object object) {
return object.getClass().isAssignableFrom( this.clazz );
}

which is opposite of what I expected.  I want to find all the objects in
working memory that implement a particular interface.  So I created my own
ObjectFilter that works like you'd expect:

public boolean accept(Object object) {
return this.clazz.isAssignableFrom(object.getClass());
}

Hope it helps someone,

Re: [rules-users] programmatic manipulation of 4.0 salience?

2007-08-17 Thread Mark Proctor 
Integer.parseInt( salienceText ) is only needed if your source is a 
string, otherwise  new SalienceInteger( 10 ) is fine. Take a look at the 
SalienceInteger to understand how it works, tuple, workingMemory are 
ignored for non dynamic environments:

Re: [rules-users] programmatic manipulation of 4.0 salience?

2007-08-17 Thread Scott Reed 

Mark,
  I think you misunderstood the issue. I know how to set the salience. The problem is that the way 
to *get* the salience of a SalienceInteger is to pass in a Tuple and WorkingMemory and there is no 
explanation of where the Tuple and WorkingMemory are supposed to come from. The only way I could 
figure out how to get the salience as I did in 3.0 is to parse the toString() result value which 
bites but works for now.
  As I asked before, will it work to call IntegerSalience.getSalience(null,null) to get a constant 
salience? If so, it would be helpful to say that in the javadocs. Also helpful, perhaps, would be a 
IntegerSalience.getValue() method with no args that would wrap Salience.getSalience( null, null ).
  I find it a little troubling that the API docs are so unreliable that users are expected to read 
the source code to understand how to use it. It would make some sense if I wanted to use the dynamic 
salience programmatically but since I am only concerned with the simple, constant case, like most 
users I expect, it seems like a lot of effort and time for something that should be easy and quick.
  I can see the benefits of dynamic salience, but I would appreciate the feature more if it hadn't 
made the simple, static case more complex.

  Thanks,
Scott

2007/8/17, Michael Waluk [EMAIL PROTECTED]:

 I found my problem, in case anyone else has this same issue (until 4.0.1which 
 may have this fixed):

 The ClassObjectFilter's accept method works like this:

 public boolean accept(Object object) {
 return object.getClass().isAssignableFrom( this.clazz );
 }

 which is opposite of what I expected.  I want to find all the objects in
 working memory that implement a particular interface.  So I created my own
 ObjectFilter that works like you'd expect:

 public boolean accept(Object object) {
 return this.clazz.isAssignableFrom(object.getClass());
 }

 Hope it helps someone,
 Michael
