- the trivial one: traverse to all neighbor MeshObjects of the start MeshObject
- traverse to the neighbor MeshObjects whose relationships with the start MeshObject are blessed with a given RoleType
- traverse a number of TraversalSpecifications in sequence
- traverse a number of TraversalSpecifications in parallel, and return the superset of all destination MeshObjects.
Also applies to a start MeshObjectSet. The destination MeshObjectSet is the superset of all destination MeshObjectSets obtained if the Traversal was performed with each member of the start MeshObjectSet individually.
