SingleValueOrContextCollector (KIE :: Decision Model Notation :: FEEL 8.30.0.Final API)

java.lang.Object
- org.kie.dmn.feel.runtime.decisiontables.SingleValueOrContextCollector<T>

All Implemented Interfaces:

Collector<T,List<T>,Object>
```
public class SingleValueOrContextCollector<T>
extends Object
implements Collector<T,List<T>,Object>
```
Custom DT collector: it only 1 output, return the output itself. If more than 1 output, return a FEEL Context (hashmap) with name of the output and its value. From the specs: The output expression of a rule in a single output decision table is simply the rule's output entry. The output expression of a multiple output decision table is a context with entries composed from the output names and the rule's corresponding output entries.
