Examples of org.apache.ode.bpel.dao.ProcessInstanceDAO

org.apache.ode.bpel.dao.ProcessInstanceDAO
BPEL process instance data access object. This object serves as the root object for data related to a particular process instance; this state includes auditing events, scopes, pick/received waiters, and the serialized process instance image.
