	MetOfficeBuddyCollectorV1 (const MetOfficeBuddyCheckParameters &options, const std::vector< float > &latitudes, const std::vector< float > &longitudes, const std::vector< int > &stationIds)

void	examinePotentialBuddy (int obsIdB) override
	Check if the observation with ID `obsIdB` can be selected as a buddy of obsIdB. If so, record its ID internally. More...

void	appendBuddyPairsTo (std::vector< MetOfficeBuddyPair > &buddyPairs) const override
	Extend `buddyPairs` with MetOfficeBuddyPair objects storing the properies of all buddy pairs found since the last call to reset(). More...

void	reset (int obsIdA) override
	Prepare the object for examination of potential buddies of the observation with ID `obsIdA`. More...

Detailed Description

An implementation of the MetOfficeBuddyCollector interface intended to produce the same results as Met Office's OPS system.

A drawback of this implementation is that counters of buddies of certain types (e.g. those from the same zonal band) are sometimes incremented prematurely – before a candidate buddy has been fully vetted – and as a result the collector may sometimes fail to collect as many valid as it should.
