[GraphHopper] How to initialize my own flagEncoder?

[John Zhao]

Thanks Peter for your answer.

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

I want to it can be parsed by the program without hard code.
