Hi Mario,<div><br></div><div>In my opinion I would drop functions like the one you mentioned and reduce the number of wrappers as much as possible.</div><div><br></div><div>I think a good and useful wrapper function is one, that selects a BBOX containing start and end point and returns records with geometries.</div>
<div>Then everyone can modify it as needed. I don't think we should simplify those basic wrappers and make assumptions like naming the cost column "length" or so.</div><div><br></div><div>What do you think?</div>

<br>
The core wrapper functions have<br>
<br>
dijkstra_sp_delta_directed<br>
astar_sp_delta_directed<br>
<br>
with "length" hard coded as cost for some reason.<br>
<br>
While astar_sp_delta_cc has a cost column parameter, but all it does<br>
is call astar_sp_delta_cc_directed with<br>
reverse_cost=false,directed=false.<br>
<br>
There is also no dijkstra_sp_delta_cc with a cost column parameter, so<br>
a user has to rename the column containing the cost value to "length"<br>
to use this clipping function. Etc....<br>
<br>
Personally I am getting confused with all these functions and would<br>
like to just trim it down to dijkstra_sp_delta and astar_sp_delta with<br>
a cost column parameter along with reverse_cost and directed<br>
parameters.<br>
<br>
Opinions?<br>
<br>
Mario.<br>
