Re: [rules-users] Do really support the containsKey() function on maps?

[Wolfgang Laun]

What is the class of $ldapResponseMap.get("zimbraDomainName")? Is it really
an InputKey? And if so, how is equals() defined in this class? Does it
return true for two different objects, one inserted in Working Memory and
another one in the Map()?

Did you explore the truth of the eval expression components?

Hello Edson/Wolfgang,
Thanks for the reply.  I am stuck with 5.0.1 in our company.  Would the map
expression that you gave work with 5.0.1?  I tried to reason it out if there
is anything wrong with my logic itself, but can think of any.  Essentially,
I have a map of Map type, where I want to see if a key
is present and if so, compare the value of that key to an expected string. 
For me it sounds like a simple logic, but please correct me if I am wrong
here.  May be my logic is not correct in drools semantics

Here is what I want to do in Java terms:

if( ldapResponseMap.get("zimbraMailDeliveryAddress").equals("abc") ) {
pfMapType.setQueryFilterCheck(true);
}  else {
if( ldapResponseMap.containsKey("zimbraDomainName") ) {
if(ldapResponseMap.get("zimbraDomainName").equals("abc") {
pfMapType.setQueryFilterCheck(true);
}
}
}

Regards,
Murty.

[Edson Tirelli]

   I think your data is somehow not matching, but you can try to simplify
your rule like this (assuming Drools 5.2):

rule "transport"
   when
   $pfMapType : MapType( name  ==  "transport" )
   $inputKey : InputKey( email == true )
   $ldapResponseMap : Map( this["zimbraMailDeliveryAddress"]
== $inputKey ||
   this["zimbraDomainName"] ==
$inputKey )
   then
   $pfMapType.setQueryFilterCheck(true);
end

Hello Wolfgang,
Thanks for the quick reply.  So if equals($inputKey) is the culprit, how can
I modify the rule to make it work?  My best guess is to do something like
this:

rule "transport" 
when 
$pfMapType : MapType( name  ==  "transport" ) 
$inputKey : InputKey( email == true ) 
$ldapResponseMap : Map() 
then 
updateTransportMap($pfMapType, $inputKey, $ldapResponseMap)
end 

And then add the function updateTransportMap() to do the required checks
that I am doing in the eval above.  Do you think of any other way?

Regards,
Murty.

[Wolfgang Laun]

Try rule "transport" without the eval and print all components of the
boolean expression in the consequence. This will show you where it fails.
(My money would be on the equals($inputKey) comparisons.)

Re: [rules-users] Do really support the containsKey() function on maps?

[dvsnmurty]

Forgot to tell you.  There is no exception on the logs.  Just the rule is not
setting the flag in the THEN portion of the rule.

[rules-users] Do really support the containsKey() function on maps?

[dvsnmurty]

Hello all,
I am having trouble with the following drools file:
===
rule "vam"
when
$pfMapType : MapType( name  ==  "vam" )
$inputKey : InputKey( email == true )
$ldapResponseMap : Map()
then
$pfMapType.setQueryFilterCheck(true);
end

rule "transport"
when
$pfMapType : MapType( name  ==  "transport" )
$inputKey : InputKey( email == true )
$ldapResponseMap : Map()
eval(
($ldapResponseMap.get("zimbraMailDeliveryAddress").equals($inputKey)) ||
(($ldapResponseMap.containsKey("zimbraDomainName") == true)
&& ($ldapResponseMap.get("zimbraDomainName").equals($inputKey))) )
then
$pfMapType.setQueryFilterCheck(true);
end
===
In the above, the rule "vam" works fine.  But the rule "transport" never
works.  Could it be because of the use of containsKey() function? 
Alternatively, I tries replacing the rule "transport" with the following
with no luck still:

===

rule "transport"
when
$pfMapType : MapType( name  ==  "transport" )
$inputKey : InputKey( email == true )
$ldapResponseMap : Map()
eval(
($ldapResponseMap.get("zimbraMailDeliveryAddress").equals($inputKey)) ||
(($ldapResponseMap.keySet().contains("zimbraDomainName")) &&
($ldapResponseMap.get("zimbraDomainName").equals($inputKey))) )
then
$pfMapType.setQueryFilterCheck(true);
end

===


Appreciate your kind attention on this.

Regards,
Murty.
