Description
ROOT as a platform is positioned at a demanding intersection of requirements:
Data acquisition and analysis in modern HENP asks for often highly optimized
implementations, while at the same time many typical users of ROOT are
non-experts and are interested in getting correct answers to their scientific
questions easily.
The C++11 standard updated the core C++ language with a number of paradigms
which allow maintaining a user-friendly, high level of abstraction without
overly compromising efficiency, e.g. through shifting work to check type
constraints or dependencies from run time to compile time (some of which were
already proposed in TR1). New C++11 features like anonymous function objects,
automatic type deduction and very easy to use abstractions for multithreaded
and asynchronous programming put formerly advanced techniques into the reach
of non-experts.
This represents both a challenge and an opportunity for ROOT: to reduce the
potential for misuse of its libraries by baffled users, and to build on a
common language of modern C++ to communicate design decisions both internally
and externally.
Starting from typical use cases problems in representative usage patterns
will be shown and possible solutions will be outlined with a focus on
usability without compromised efficiency.
