Table Task

This task works with tables with unique keys. It is designed to be very fast and handle large tables. It is a hardware configuration requirement for there to be enough RAM on the server workstation to hold all of the active tables.

01   public TableLookupResult process (DecisionRequest decisionRequest) 
                              throws TaskException, Exception
02   {
03      lookupKey.setKey (decisionRequest, keyFields);
04
05      try
06      {
07         userExit.setLookupKey (decisionRequest, lookupKey);
08      }
09      catch (Exception xcp)
10      {
11         throw xcp;
12      }
13
14      boolean recFound = binTable.search (lookupKey.getKey(), lookupResults.getPayload());
15
16      lookupResults.setOperationResults (recFound == true);
17      lookupResults.setRecordFound      (recFound);
18
19      if (recFound == true)
20      {
21         lookupResults.setResults (decisionRequest, payloadFields);
22      }
23
24      try
25      {
26         userExit.postLookup (decisionRequest, lookupResults);
27      }
28      catch (Exception xcp)
