如何通过Shark api应用获得父流程?

ExecutionAdministration ea = Shark.getInstance().getAdminInterface().getExecutionAdministration();
ea.connect(userName, password, engineName, null);

// subProcId为子流程序号

wfeas = ea.getProcess(subProcId).get_sequence_history(0);

if ( wfeas != null )
{
for ( int i = 0; i < wfeas.length; i++ )
{
if ( wfeas[i].event_type().equals("processCreated") )
{
WfCreateProcessEventAudit wpea = (WfCreateProcessEventAudit)wfeas[i];
// parentProcId 为父流程序号
parentProcId = wpea.p_process_key() == null ? "" : wpea.p_process_key();

break;
}
}
}
