[jboss-jira] [JBoss JIRA] (DROOLS-5061) DMN codegen DMNContext and DMNResult

[Matteo Mortari (Jira)]

     [ https://issues.redhat.com/browse/DROOLS-5061?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Matteo Mortari updated DROOLS-5061:
-----------------------------------
    Description: 
A codegen facility is required to generate statically code strongly typed for the input/output of a DMN model, considering also the data types defined inside the DMN model as ItemDefinition. 

Surface and interface common to:
* BPMN integration: when invoking DMN from BPMN, the return of the evaluation is a Map and not the domain model
* Kogito/OpenAPI/Swagger: when using the codegenerated version, annotation shall explain the swagger API the expected input/output type of the REST request for DMN
** for Quarkus based, use RegisterForReflection annotation
** use MP validation for allowedvalues 
* DMN Editor: when importing a Java Class in the editor, it shall use the user-supplied Java Class 

Documentation:
* the programmatic use of the generated classes, directly, is DISCOURAGED
* if anything, a programmatic use will eventually be stable by making use of the available interfaces in kie-dmn-core
