Description
User Story (Required on creation):
For generated graph of tables and literal expresions, we need to return not only the decision result of the final decision, but also a map of all intermediate results.
I built a spike for this here: I build a spike for this here: https://github.com/jangalinski/dmn-literal-expression-spike
Functional Requirements (Required before implementation):
Currently the DefaultDmnEngine creates the DmnDecisionContext via "new" ... so in order to hook into the default behavior, I have to implement my own engine configuration, which builds my own engine implementation and than calls my own decision context ... where I just collect results inside the for loop ...
By switching to an interchangeable factory + interface for the dmnDecisionContext (keeping the default implementation) I would just have to register my custom context, not re-implementing the engine and its configuration.
Technical Requirements (Required before implementation):
Introduce an Interface for DefaultDmnDecisionContext (wonder why there is non ... all other classes in the den-engine module that start with Default are ... default implementations of an interface ...) and a factory that can create such instance.
