[GraphHopper] Reg: GhRequest and handling new params

[Manikanta Kondeti]

Hi,

   This is Manikanta. I've been an avid user/developer in pgrouting. After
seeing the fastness in graphhopper, I'm pretty much interested in
understanding it as a user and developer. Also I am basically new to Java,
hoping its not a problem to learn it as it looks a lot like c++. I've read
all the docs and I can clearly understand the inner underlying techniques
which makes it faster. I love the way you guys building the graph and also
contraction hierarchies stuff though its not useful for dynamic graph.

    Now I want to tweak the code and basically write a new custom weighting
class. So the first step in doing it is to tweak the GhRequest and extend a
new class from it or use the same class with additional methods and member
variables. Can you give me an overview of how to proceed? My plan is to
take a few(10) params and pass it to the custom weighting. Is it possible?
Giving me a reference link would help me a lot. Sorry if this is very basic
question. Hope you understand.

Thank you,
Mani
