Hello,
I am new to Java and Drools and have a doubt regarding the sequence of rules'
execution as stated below :-
Scenario:- I have a scenario wherein I have to apply multiple rules on multiple
columns coming in a file. To simulate that I created a 2-D array as follows
String[][] data = {
{"1791","8459625","78458745","20120610","20120610" },
{"1792","8459623","78458745","20120610","20120610" },
{"1793","8459624","78458745","20120610","20120610" },
{"17944","8459626","78458745","20120610","20120610"}
};
Here each column of corresponds to a member for the following class
public class DailyPLC {
private String Id; // This value will correspond to data[i][0]
private String productCode; // This value will correspond to data[i][1]
private String customerCode; // This value will correspond to data[i][2]
private String date1; // This value will correspond to data[i][3]
private String date2; // This value will correspond to data[i][4]
private int rowNumber; // The row number to keep a track of row for which
the record exists
/*Getters and Setters defined for each of them*/
}
I have to perform checks on each of the columns, and the intent is to create
all the rules that I need for the entire array and save it in a single drl
file. Also, at the execution time, all the rules should be applied - either at
once or sequentially - to all the rows of the data.
Approach:- I tried the following
1. Created an ArrayList
ArrayList<DailyPLC> alPLCArrayList = new ArrayList<DailyPLC>();
2. Iterated over the data and stored each row into a field of the object
of DailyPLC class.
3. For every iteration, added the object into the array list.
alPLCArrayList.add(plcToday); // The plcToday is the object of the DailyPLC
class
4. When executing the rules, I am adding all the items of the ArrayList
one by one and adding into the Knowledge Session.
for(DailyPLC d : alPLCArrayList)
{
ksession.insert(d);
}
Problem Faced :- The problem that I faced is that when I do FireAllRules, the
rule only validates the last record. The intent is that it should traverse the
list and give a result for all the members of the list.
Have I missed something here?
Please assist. Let me know in case you need any more information
Thanks in Advance,
Amal Gupta
