find(*path) click to toggle source

recursive find starts at the node and continues to the parent

def find(*path)
  get(*path) || @parent && @parent.find(*path)
end
Also aliased as: []
get(*path) click to toggle source

looks for the path from this node DOWN. will not delegate to parent

def get(*path)
  key = path.shift
  value = @data[key.to_s]
  return value if (nil != value) && path.empty?

  value && value.get(*path)
