Class podio::RelationRange

template<typename ReferenceType> class RelationRange

A simple helper class that allows to return related objects in a way that makes it possible to use the return type in a range-based for loop.

Public Types

using ConstIteratorType = typename std::vector<ReferenceType>::const_iterator

Public Functions

RelationRange() = delete

inline RelationRange(ConstIteratorType begin, ConstIteratorType end)

inline ConstIteratorType begin() const: begin of the range (necessary for range-based for loop)

inline ConstIteratorType end() const: end of the range (necessary for range-based for loop)

inline size_t size() const: convenience overload for size

inline bool empty() const: convenience overload to check if the range is empty

inline ReferenceType operator[](size_t i) const: Indexed access.

inline ReferenceType at(size_t i) const: Indexed access with range check.
