Detailed Description🔗

template <typename IceoryxTerminal ,
typename ExternalTerminal >
class iox::gw::Channel;

A data structure representing a channel between Iceoryx and an external system.

The class couples related iceoryx and external interfaces that communicate with eachother to form the communication channel. These interfaces are conceptualized as channel "Terminals".

The structure holds pointers to the instances of the terminals. The terminals can be created and managed externally, in which case the structure only serves as a means of coupling the two. This can be achieved by simply calling the constructor with pointers to them.

Alternatively, the class can manage the terminals internally in a static object pool, automatically cleaning them up when the channel is discarded. This can be achieved via the Channel::create method.
