#valid? ⇒ Boolean

Override this method in your Configurable (optional)

Called once during evaluation of the config file. Return true if valid, false otherwise

A convenience method ‘complain’ is available that will print out a message and return false, making it easy to report multiple validation errors:

def valid?
  valid = true
  valid &= complain("You must specify the 'pid_file' attribute for :memory_usage") if self.pid_file.nil?
  valid &= complain("You must specify the 'above' attribute for :memory_usage") if self.above.nil?
  valid
end

Returns:

  • (Boolean)
