Difference between org.drools.runtime.process.ProcessInstance and org.drools.runtime.process.WorkflowProcessInstance

[d.y.]

Hey guys,

I wonder what the difference between these two classes is. My guess is that WorkflowProcessInstance is an instance of a process modeled by a bpmn file and ProcessInstance is an instance of a process that contains anything from drools like decision tables or drools rules!?

Process instance is a more abstract concept about process only, not rules or decision tables. Imagine that you want to run another type of process with the engine you just need to plug that there as an implementation of ProcessInstance. For example if you want to run an instance of a process with a different set of nodes (different execution semantic) you can add your own implementation there.

Cheers
