## org.drools.runtime.process
Interface ProcessInstance

All Superinterfaces:
  EventListener

All Known Subinterfaces:
  ProcessInstance, WorkflowProcessInstance, WorkflowProcessInstance

All Known Implementing Classes:
  ProcessInstanceImpl, RuleFlowProcessInstance, WorkflowProcessInstanceImpl

    public interface ProcessInstance

extends EventListener

A process instance represents one specific instance of a process that is currently executing. Whenever a process is started, a process instance is created that represents that specific instance that was started. It contains all runtime information related to that instance. Multiple process instances of the same process can be executed simultaneously. For example, consider a process definition that describes how to process a purchase order. Whenever a new purchase order comes in, a new process instance will be created for that purchase order. Multiple process instances (one for each purchase order) can coexist. A process instance is uniquely identified by an id. This class can be extended to represent one specific type of process, e.g. `WorkflowProcessInstance` when using a `WorkflowProcess` where the process logic is expressed as a flow chart.

  `WorkflowProcessInstance`
