Package org.kie.dmn.feel.runtime.decisiontables

Class SingleValueOrContextCollector<T>

  • All Implemented Interfaces:
    java.util.stream.Collector<T,​java.util.List<T>,​java.lang.Object>
    public class SingleValueOrContextCollector<T>
extends java.lang.Object
implements java.util.stream.Collector<T,​java.util.List<T>,​java.lang.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.
