def cache_key(point_key, scope_hash)
  c_point = cache_point(point_key, scope_hash)
  c_key = Cachecataz[:get, c_point].to_s.strip
  return "#{c_key}#{Cachecataz::Config[:ns_delim]}" << c_point 
end

#cache_point(point_key, scope_hash) ⇒ Object

Determines and returns the cache_point putting i.to_s first in the scope_hash lookup because primarily using with self.attributes in rails which is string keyed

end

#cache_scope(point_key, *c_scope) ⇒ Object

Method used in the Class to defined a cachecataz namespace assigns the scope to a class instance variable with the point_key as key

Parameters:

  • point_key (Symbol) —

    the name of the cachecataz namespace

  • c_scope (Array) —

    the symbols that defined the scope of the namespace
