メソッドの詳細

newRQMessage4Root

RQMessage newRQMessage4Root(MessagingFramework sgmf,
                            Collection<SubRange> subRanges,
                            QueryId qid,
                            Object query,
                            TransOptions opts)

create a (subclass of) RQMessage for new range query instance.

パラメータ:

sgmf - messaging framework

subRanges - the subranges.

qid - the query id.

query - the query object.

opts - the transport options.

戻り値:

subclass of RQMessage

assignDelegate

List<SubRange> assignDelegate(Object query,
                              SubRange queryRange,
                              NavigableMap<DdllKey,Link> allLinks,
                              Collection<Endpoint> failedLinks)

split the given query range and assign an appropriate delegation node for each subrange.

パラメータ:

query - query parameter

queryRange - query range

allLinks - links (including keys) to split the query range

failedLinks - (maybe) failed links

戻り値:

subranges

assignDelegates

StrictMap<Id,List<SubRange>> assignDelegates(RQMessage msg,
                                             List<SubRange[]> closeRanges,
                                             List<DKRangeRValue<?>> rvals)

split the given query range and assign an appropriate delegation node for each subrange.

パラメータ:

msg - query message

closeRanges - List of {[predecessor, n), [n, successor}}, where n is myself.

rvals - the list to store the results.

戻り値:

the map of id and subranges.

rqExecuteLocal

void rqExecuteLocal(RQMessage msg,
                    List<SubRange> list,
                    List<DKRangeRValue<?>> rvals)

resolve (fill-in) range query results that are locally available.

パラメータ:

msg - the query message.

list - list of subranges that are locally available.

rvals - list to store the results
