ROOT::Detail::TRangeStaticCast< T > Class Template Reference

template<class T>
class ROOT::Detail::TRangeStaticCast< T >

TRangeStaticCast is an adaptater class that allows the typed iteration through a TCollection.

This requires the collection to contains element of the type requested (or a derived class). Any deviation from this expectation will only be caught/reported by an assert in debug builds.

This is best used with a TClonesArray, for other cases prefered TRangeDynCast.

The typical use is:

for(auto bcl : TRangeStaticCast<TBaseClass>( *tbaseClassClonesArrayPtr )) {
assert(bcl && bcl->IsA()->InheritsFrom(TBaseClass::Class()));
... use bcl as a TBaseClass*
}
for(auto bcl : TRangeStaticCast<TBaseClass>( tbaseClassClonesArrayPtr )) {
assert(bcl && bcl->IsA()->InheritsFrom(TBaseClass::Class()));
... use bcl as a TBaseClass*
}
