ROOT::RProxiedCollectionField::RCollectionIterableOnce Class Reference

Allows for iterating over the elements of a proxied collection.

RCollectionIterableOnce avoids an additional iterator copy (see TVirtualCollectionProxy::GetFunctionCopyIterator) and thus can only be iterated once.

Constructor & Destructor Documentation

◆ RCollectionIterableOnce()

ROOT::RProxiedCollectionField::RCollectionIterableOnce::RCollectionIterableOnce ( void * collection,
const RIteratorFuncs & ifuncs,
TVirtualCollectionProxy * proxy,
std::size_t stride = 0U )
inline

Construct a RCollectionIterableOnce that iterates over collection.

If elements are guaranteed to be contiguous in memory (e.g. a vector), stride can be provided for faster iteration, i.e. the address of each element is known given the base pointer.
