TRangeDynCast

template<typename T>

using TRangeDynCast = ROOT::Detail::TRangeCast<T, true>

TRangeDynCast is an adapter class that allows the typed iteration through a TCollection.

The typical use is:

for(auto bcl : TRangeDynCast<TBaseClass>( *cl->GetListOfBases() )) {
    if (!bcl) continue;
    ... use bcl as a TBaseClass*
}
for(auto bcl : TRangeDynCast<TBaseClass>( cl->GetListOfBases() )) {
    if (!bcl) continue;
    ... use bcl as a TBaseClass*
}

Template Parameters

T	The new type to convert to.
