def ==(other)
  other.is_a?(FeatureFlag) && other.data == self.data
end

#[](key) ⇒ Object

This method allows us to read properties of the object as if it’s just a hash. Currently this is necessary because some data store logic is still written to expect hashes; we can remove it once we migrate entirely to using attributes of the class.

  • 5.5.0

parameter is unused, but may be passed if we’re using the json gem

#to_json(*a) ⇒ Object

Same as as_json, but converts the JSON structure into a string.
