The WfPRocessMgrImpl implements the WfProcessImpl interface. The con-
structor takes a process definition as an argument. All the methods are quite
simple since they are getters and setters. Most of the methods defined by
JFlow in this and other interfaces are like these.
package WfEngine;
...
class WfProcessMgrImpl implements WfProcessMgr {
private Vector instances;
private WfProcessDefinition definition;
private process_mgr_stateType state;
private String description;
WfProcessMgrImpl(WfProcessDefinition definition) {
This.definition # definition;
state # process_mgr_stateType.enabled;
instances # new Vector();
