C++ properties and observer pattern
Introduction¶
xproperty
is a C++ library providing traitlets-style properties.
xproperty
provides an implementation of the observer patterns relying on C++ template and preprocessor metaprogramming techniques.
Properies of observed objects have no additional memory footprint than the value they hold. The assignment of a new value is simply replaced at compiled time by
the call to the validator for that property
the actual underlying assigment
the call to the observor for that property.
We also provide the implementation of an xobserved
class whose static validator and observer are bound to a dynamic unordered map
of callbacks that can be registered dynamically.
xproperty
requires a modern C++ compiler supporting C++14. The following C++ compilers are supported:
On Windows platforms, Visual C++ 2015 Update 2, or more recent
On Unix platforms, gcc 4.9 or a recent version of Clang
