Class Method Details

.const_missing(name) ⇒ Object

Const missing hook to look up deprecated constants defined with deprecate_constant. Emits a warning to the logger and returns the replacement constant. Will call super, most likely causing an exception for the missing constant, if name is not found in the deprecated_constants collection.

    new_const[:replacement]
  else
    super
