Hi,
I have an scenario as below..
In a list there are some values in the order like CAR,CYCLE,CAR,BIKE,CAR
Now when (vehicle==CAR) using "from" this must match with the first CAR
skipping third and last.
How to match like that as From usually comes from backward.
Thanks
Salt

Hi Laune,
Vehicles list contains the values name and qty and the values are
car,10
jeep,20
lorry,30
car,30
Below is my implementation for that scenario which i have asked.
rule "HelloWorld_13"
salience 65523
when
$p1:Policy()
$trandet:Vehicle(name in ("CAR")) from $p1.vehicleslist
then
System.out.println($trandet.getQty());
end
The result for the above rule is
30
10
but i need 10 alone which is at the top of that list.. is that possible.?
and when googling found that if we use salience along with 'from' its
possible..
Please share your thoughts on the above.
Thanks
Salt

You'll have to separate the logic for determining that the item you
are looking for is in the list from the access to the first occurrence.
rule "find first 'car'"
when
$p1:Policy()
$carList: List( size > 0 )
from collect ( Vehicle( name == "car" )
from $p1.vehicleslist )
$first: Vehicle( ) from $carList.get( 0 )
then
System.out.println( $first );
end

You should also be able to use runtime salience:
rule "Helloworld_13"
salience ( 65535 - $list.indexOf( $trandet ) ) // lower indexes first
when
$p1 : Policy( $list : vehicleslist )
$trandet : Vehicle( name in ("CAR") ) from $list
then
...
end

Hi david,
Have doubt in the below implementation. As per my understanding the salience
are used to execute the rules in an order. The rule with higher salience
will execute first.
By the below implementation will that affect the rule execution order.
salience ( 65535 - $list.indexOf( $trandet ) ) // lower indexes first
Thanks

Correct.

salience ( 65535 - $list.indexOf( $trandet ) ) // lower indexes first
It does: indexOf returns 0, 1, 2,..., every so often, and thus the
salience values will be computed accordingly.
But as you wrote you want to fire the rule for the first "car" in your
list *only*, I suppose it isn't quite what you want.

Thanks Laune.
I thought using that salience would be helpful for below scenario but it
seems not possible.
An list contains values like
Example with dummy values
AA - 1
A - 2
B - 3
A - 4
Need to retrieve the latest success one (Failed ones - if the list contains
AA before A then that is failed)..
For the above one the result should be B and 3
Few scenarios
AA - 1
A - 2
A - 3
A - 4
B - 5
Result should be A - 3
AA - 1
A - 2
AA - 3
B - 4
A - 5
Result should be B - 4
Kindly share your thoughts on this (salience or without salience)..
Thanks

You are changing the requirements, from the first element with "car" to
something
else now, aren't you?
Just write a Java method that computes the index of a list of values
(XX-nn) that fulfils
your requirements, and then we'll continue the discussion of how to use it
in
rules.

Sorry for the confusion. Actually i am not changing the requirement. The one
you replied is perfectly working for that. This is another scenario. Anyhow
i will get back to you with java method.
Thanks

for the above java method
input values are
chars qty
AA 1
A 2
B 3
A 4
it will return 3, B
and for the below it wil be 1,A
chars qty
A 1
A 2
B 3
The above two scenarios needs to be covers in rules.
Thanks

Hi Laune,
Please find the java method below..
int statusApass=0;
int statusBpass=0;
for(int i = 0;i<policy.getList().size();i++)
{
if(policy.getList().get(i).getChar().equals("A")||policy.getList().get(i).getChar().equals("B"))
{
System.out.println("STEP`1"+policy.getList().get(i).getChar());
if(policy.getList().get(i).getChar().equals("A"))
{
statusApass =1;
for(int j=0;j<=i;j++)
{
if(policy.getList().get(j).getChar().equals("AA"))
{
statusApass=0;
}
}
}
else if(policy.getList().get(i).getChar().equals("B"))
{
statusBpass=1;
for(int z=0;z<=i;z++)
{
if(policy.getList().get(z).getChar().equals("BB"))
{
statusBpass=0;
}
}
}
}
if(statusApass==1||statusBpass==1)
{
System.out.println("policy"+policy.getList().get(i).getQty()+","+"policy"+policy.getList().get(i).getChar());
break;
}
}
Thanks

Put this code into method of Policy with the signature
List<Vehicle> getValidAB()
where the returned List either contains the element you want or is
empty. Then you can write
rule "find first 'car'"
when
$p1:Policy()
$carList: List( size > 0 )
from collect ( Vehicle( name == "car" )
from $p1.getValidAB() )
$first: Vehicle( ) from $carList.get( 0 )
then
System.out.println( $first );
end
