Class: AMON::Metadata

Inherits:
DocumentPart show all
Defined in:
lib/amon/metadata.rb

Overview

TODO:

This doesn’t yet support arbitrarily nested metadata, so you can’t have JSON like so:

"metadata": {
  "foo": {
    "bar": "baz"
  }
}

And then access:

object.metadata.foo.bar # => "baz"

However, in the meantime you could do:

object.metadata.foo[:bar] # => "baz"

(As the JSON is full parsed into a nested hash.)

Metadata associated with a Device. The metadata section of an AMON document can have an arbitrary number of fields, so this class uses ‘method_missing` to look them up and respond appropriately.
