Hey Alexandr,
If you wanted to do it using python, and you didn't have swift installed
you can use pickle and unpickle the builder. something like:
import pickle
builder = pickle.load(open('<path to builder>')
Then you'd have a python dict structure, where I think you can
'builder['devs']'
or with swift installed you can use the RingBuilder class:
from swift.common.ring.builder import RingBuilder
builder = RingBuilder.load('<path to object.builder>')
builder.devs
Where builder.devs will be a list of dictionary objects. You could then
json-ify and output for java to read or put it into an easier to pass list.
There could be a much simpler way, but I'm a Python dev, so this is what
I'd do ;)
Regards,
Matt
