Detailed Description

template<typename Derived, typename index_t, bool read_only>
class Acts::TrackProxyCommon< Derived, index_t, read_only >

Common CRTP implementation shared by the various track proxy front-ends.

The derived proxy only needs to expose the component helpers, while this base class wires up the commonly used convenience methods.

Template Parameters

Derived	The proxy implementation inheriting from this base
index_t	The index type used by the proxy
read_only	Whether the proxy provides mutable access
