Modifier and Type	Method and Description
void	Fragment.addReceiveExchange(Exchange e, Fragment fragment)
void	Fragment.addSendExchange(Exchange e, Fragment sendingToFragment)
protected QueryWorkUnit	SimpleParallelizer.generateWorkUnit(OptionList options, CoordinationProtos.DrillbitEndpoint foremanNode, UserBitShared.QueryId queryId, Fragment rootNode, PlanningSet planningSet, UserSession session, BitControl.QueryContextInformation queryContextInfo)
Wrapper	PlanningSet.get(Fragment node)
QueryWorkUnit	SimpleParallelizer.getFragments(OptionList options, CoordinationProtos.DrillbitEndpoint foremanNode, UserBitShared.QueryId queryId, Collection<CoordinationProtos.DrillbitEndpoint> activeEndpoints, Fragment rootFragment, UserSession session, BitControl.QueryContextInformation queryContextInfo) Generate a set of assigned fragments based on the provided fragment tree.
protected PlanningSet	SimpleParallelizer.getFragmentsHelper(Collection<CoordinationProtos.DrillbitEndpoint> activeEndpoints, Fragment rootFragment) Helper method to reuse the code for QueryWorkUnit(s) generation
