<br>
if you load GH from extracted files you setup the GraphHopper
class the same way as you would when doing the import.<br>
I.e. you will have to configure the GraphHopper class identical as
you did for the import.<br>

<div>I mean "combne" is if I have something inside
properties like:</div>
<div>graph.flagEncoders=xxxcar|speedFactor=5.0|speedBits=5|turnCosts=true,
bike, mtb, foot<br>

<div>I want to it can be parsed by the program

<div>Hi,<br>
<br>
I'm not sure what you mean with 'combine'.
You can mix Java API and read from config
too e.g. via<br>
<br>
graphHopper.init(CmdArgs.readFromConfig(..))<br>
graphHopper.setEncodingManager(new
YourFlagEncoder(), new CarFlagEncoder(),
...)<span><br>

JavaScript (TeaVM) and iOS, and for them
we need to avoid some stuff.<br>

<div>Hi John,<br>
<br>
if you have a custom
flagencoder why not just call<br>
new EncodingManager(new
YourFlagEncoder()) ?<br>
<br>
Reflections was abandoned due
to portability reasons but
also it is not really
necessary here, especially as
you use it as a library and
you have a custom flag encoder
anyway.<br>
<br>
