Detailed Description

A safe iterator on jet constituents.

Modifying the signal states of jet constituents may be dangerous as it can accidentally leave the state undefined for subsequent algorithm. This implementation is safe. This iterator is a simple copy of the iterator 4mom with the desired state. It should be enough for most use case. If access to the real constituent is necessary, this is still possible throug JetConstituentIterator::get_real_constit()
