Overview

Base class for CIE supplement identifiers (Supplement, Corrigendum).

Like ISO/IEC/BSI/JCGM, a CIE supplement wraps its base document as a nested full identifier (+base+, a Pubid::Cie::Identifier), rather than flat base_number/base_year strings. This lets CIE supplements participate in the shared base_document / drop_supplements / matches? vocabulary relaton uses to match a citation to its base standard.

Concrete subtypes: Supplement (-SPN), Corrigendum (/CorN).

Instance Method Details

#base_document ⇒ Object

The underlying standard, with supplement layer(s) peeled recursively.

# File 'lib/pubid/cie/supplement_identifier.rb', line 29

def base_document
  base&.base_document || self
end

#drop_supplements ⇒ Object

Dropping one supplement layer yields the wrapped base identifier.

def drop_supplements
  base || self
end

#supplement_number ⇒ Object

Uniform, class-agnostic supplement interface (shared by Supplement and Corrigendum) so callers never special-case corrigenda. supplement_type and supplement_year are defined per subclass.
