    params
end

fillPathParams(path, params) click to toggle source

Set :Domain and :IPs from path to params @param path [String] source data path @param params [Hash] target params @return [Hash] result params

# File lib/dnsupdater.rb, line 68

    raise Error, 'Not enough parameters!' if parts.count < 3

    params
end

Set uri info to params @param uri [Addressable::URI] source uri @param params [Hash] target params @return [Hash] result params
