public interface ProcessInstance
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.
