Macro Definition Documentation

hdtree_class_version

#define hdtree_class_version

(

VERS

)

using version = std::integral_constant<int, VERS>

define the version number for a class

Put this macro within the class declaration in order to define its version number as a class used for data serialization in hdtree. Without this macro, the version will default to zero.
