void Clear ()

Clear all fields without freeing memory, so that it avoid reallocation when reused.

bool IsCleared ()

Return true if all fields are cleared/empty.

GlobalTopologyData ComputeGlobalTopologyData (const UberStruct::InstanceMap & uber_structs, const LinkTopologyMap & links, TransformHandle::InstanceId link_instance_id, TransformHandle root)

Computes the GlobalTopologyData consisting of all TransformHandles reachable from |root|.

|root.GetInstanceId()| must be a key in |uber_structs|, and |root| must also be the first

TransformHandle in the topology vector of the UberStruct at that key.

When the function encounters a TransformHandle whose instance ID is the |link_instance_id|,

it will search for that handle in the |links| map. If a value is found, that value is treated

as the root transform for a new local topology. If this new root transform has an entry in

|uber_structs| AND the first entry of that UberStruct's topology vector matches the new root

transform, then the new local topology is folded into the return topological vector. If either

of the aforementioned conditions is false, the TransformHandle on the other end of the link

will not be included.

TransformHandles with the |link_instance_id| are never included in the final topology,

regardless of whether or not the link resolves.
