Detailed Description

A forwarder class for std::array.

std::array persistence in Root is treated in a way that makes classes deriving from it unsuitable for automatic dictionary generation, due to rootcling not generating the dictionary for the std::array base class. More information are available on the Root forum and bug tracker:

https://root-forum.cern.ch/t/cant-generate-dictionary-for-std-array-containing-a-custom-class/32592 https://sft.its.cern.ch/jira/browse/ROOT-9943

Until a proper fix is implemented in Root, the workaround is to define a class that implements the interface of std::array by forwarding all the calls to a private std::array member, and inherit from this forwarder class. In this way std::array is no longer a base class and there's no need to generate a dictionary for it, making rootcling happy again.

The declaration of ArrayForwarder is adapted from a copy-paste of std::array shipped with gcc 8.2.1.
