> Depending on the Siddhi query, events received from Siddhi either contain a *non-primitive data structure*, e.g. for the trend detection [1] it is a LinkedList,
> Returned Siddhi event looks like this: 
> {code:java}
> Event{timestamp=1590427035172, data=[[24661], [10], [c], [1590427035166]], isExpired=false}{code}
>  or
> contain a *primitive data structure*, e.g. for the numerical filter (siddhi) [2] as an Integer.
> Returned Siddhi event looks like this:
> {code:java}
> Event{timestamp=1590427127153, data=[24753, 36, b, 1590427127149], isExpired=false}{code}
>  
> Now, in the wrapper when trying to convert to a StreamPipes event in the 
> {code:java}
> toSpEvent(...){code}
> method this fails due to casting error.
