Enumeration Type Documentation

ObjectType

enum xAODType::ObjectType

Type of objects that have a representation in the xAOD EDM.

xAOD classes identify themselves by all of them providing a function with the signature:

xAOD::Type::ObjectType type() const;

This can be used to easily identify what sort of object some generic code is dealing with, avoiding doing a lot of dynamic_cast-s instead.

Note that Doxygen doesn't allow to group enumeration variables together like it does for members of a class, that's why the grouping comments are not created according to the Doxygen rules.
