ROOT::Internal::RPagePool::RPagePosition Struct Reference

Used in fLookupByKey to store both the absolute and the cluster-local page index of the referenced page.

This allows to do binary search for one or the other. Note that elements in fLookupByKey must have both values to be valid. If RPagePosition is used as a search key, only one of the two needs to be set.
