File objects.hpp¶

Core API objects.

Includes the majority of the objects that are used when using the SLAMcore API. Along with their definition, we define load_minimal, save_minimal helper functions as well as the operator<< for storing/dumping their types.

Note

Notice that the majority of the classes are suffixed with *Interface. That’s because when you get access to the corresponding instance, you do via a pointer type (namely std::shared_ptr or the class member aliases Ptr, CPtr) and not through the actual class instance.
