Detailed Description

template<typename... MHRWStatsCollectors>
class Tomographer::MultipleMHRWStatsCollectors< MHRWStatsCollectors >

A simple MHRWStatsCollector interface which combines several stats collectors.

A MHRandomWalk object expects one instance of a MHRWStatsCollector (see MHRWStatsCollector Interface); in case you wish to provide several stats collectors, you should use a MultipleMHRWStatsCollectors instance which combines all your preferred stats collectors.

The obscure variadic templating of this class should not scare you—it's relatively straightforward to use:

// some stat collectors
MyStatCollector1 statcoll1(..);
MyStatCollector2 statcoll2(..);
MyStatCollector3 statcoll3(..);

// we combine them into one single "stat collector interface", which we can then
// give as argument to the MHRandomWalk object:
MultipleMHRWStatsCollectors<MyStatCollector1,MyStatCollector2,MyStatCollector3>
    multistatcollector(statcoll1, statcoll2, statcoll3);

MHRandomWalk<...> myrandomwalk(..., multistatcollector,...);
// now, the random walk will call the callbacks in `multistatcollector', which
// will relay the callbacks to all the given stat collectors `statcoll*'.

The number of stat collectors that were defined is accessible through the constant enumeration value NumStatColl.
