Why don't has Physics.LinecastAll scripting API?

I want to get all gameObjects from point A to point B, but didn’t find LinecastAll in scripting API.

Now I use this method, maybe it’s not fine…

Vector3 point_A;
Vector3 point_B;

while ( Physics.Linecast ( point_A, point_B, out hitInfo ) )
{
     point_A = hitInfo.point + (point_B - point_A) * 0.1f;
} 

Is there any other way?
Thankes!

I know i’m like 4 years late, but for anyone who sees this later.
I believe you can use Physics.RaycastAll(point_A, point_B - point_A, Vector3.Distance(point_A, point_B));
This will do a normal raycast, but have the same effect.
