def create_reflection(macro, name, options, datastax_rails)
  klass = options[:through] ? ThroughReflection : AssociationReflection
  reflection = klass.new(macro, name, options, datastax_rails)
  self.reflections = reflections.merge(name => reflection)
  reflection
end

#reflect_on_all_associations(macro = nil) ⇒ Object

Returns an array of AssociationReflection objects for all the associations in the class. If you only want to reflect on a certain association type, pass in the symbol (:has_many, :has_one, :belongs_to) as the first parameter.

Example:

Account.reflect_on_all_associations             # returns an array of all associations
Account.reflect_on_all_associations(:has_many)  # returns an array of all has_many associations
