Macro Definition Documentation

GTSAM_CONCEPT_GROUP_INST

#define GTSAM_CONCEPT_GROUP_INST

(

T

)

Value:

template class gtsam::IsGroup<T>;

Macros for using the IsGroup.

• An instantiation for use inside unit tests
• A typedef for use inside generic algorithms

NOTE: intentionally not in the gtsam namespace to allow for classes not in the gtsam namespace to be more easily enforced as testable

GTSAM_CONCEPT_GROUP_TYPE

#define GTSAM_CONCEPT_GROUP_TYPE

(

T

)

Value:

typedef gtsam::IsGroup<T> _gtsam_IsGroup_##T;
