Description
I have a R script which returns a list.
FraudDetectionList <- function(debitTime,debitAmount,averageMonthlyBalance)
{
debitTimeLength <- length(debitTime)
debitAmountLength <- length(debitAmount)
i<-2
#Need to make 3 debits to trigger FraudDetection rule. Hence first condition is to see time length(Number of time history values) is greater than 2
while(debitTimeLength>2)
{
while(i<debitTimeLength)
{
SumOfDebits <- 0
k<-debitTimeLength-i
for(z in debitTimeLength:k)
{
SumOfDebits <- SumOfDebits+debitAmount[[z]]
}
if((debitTime[[debitTimeLength]]!=0) && (debitTime[[debitTimeLength]]-debitTime[[debitTimeLength-i]]<=FraudCriteria.interval) && (SumOfDebits>(FraudCriteria.debitsPercent*averageMonthlyBalance)))
{
result=list(TRUE,"FraudDetected")
return(result)
}
else
{
i <- i+1
}
}
debitTimeLength <- debitTimeLength-1
i<-2
}
result=list(FALSE,"OK")
return(result)
}
How to receive Datalist from TIBCO Enterprise Runtime for R and extract its data in a TIBCO BusinessEvents Rule/Rulefunction?
Environment
All
Resolution
Complex Data structure DataList TERR type is mapped to Object in TIBCO BusinessEvents Rule/Rulefunction. Use Object for the DataList(com.tibco.terr.TerrList) returned from TERR, and then use the Analytics.DataList.getElement catalog function to extract the list(Object[]).
See the code example below to extract elements returned from TERR in a BE Rule/Rulefunction:
See the code example below to extract elements returned from TERR in a BE Rule/Rulefunction:
Object[] TerrResult = Analytics.Engine.invokeTERRFunction("TerrEngine","FraudDetectionList",debitTime,debitAmount,averageMonthlyBalance);
Object TerrResultList = TerrResult[0];
Object[] firstElement = Analytics.DataList.getElement(TerrResultListObject, 0);
int fraudFlag = Number.valueOfString(firstElement[0]);
Object[] secondElement = Analytics.DataList.getElement(TerrResultListObject, 1);
String fraudMessage = secondElement[0];
