Exception: Eeml::Exceptions::MissingNode

Inherits:
BadEeml show all
Defined in:
lib/eeml/exceptions.rb

Overview

A structured exception which holds info about what was missing and from where. Note: Some reasons we don’t just hold everything in an unstructured exception message:

  1. some bits might be useful for dev but not for the public,

  2. testing is simplified by having the missing node name recorded explicitly (rather than in a human-readable, changeable string).
