def fetch_identifier(name)
  val = @encoded_ids[name]
  val = LiteCable.config.identifier_coder.decode(val) unless val.nil?
  instance_variable_set(
    :"@#{name}",
    val
  )
end

#identifier ⇒ Object

Return a single connection identifier that combines the value of all the registered identifiers into a single id.

You can specify a custom identifier_coder in config to implement specific logic of encoding/decoding custom classes to identifiers.

By default uses Raw coder.
