Overview

Single dispatch point mapping a JP record's type string to the correct Openphar::Models::JP::* subclass.

JP's HTML parser already produces a type string (e.g., "CrudeDrugMonograph"); the classifier trusts it and maps to the JP-specific subclass. Falls back to JP::Monograph for unknown type strings.

MECE invariant: every type string in TYPE_MAP classifies to exactly one subclass; every other input falls back to the base.

.classify(type_string:, name: nil) ⇒ Class

Returns a subclass of Openphar::Models::JP::Monograph.

Parameters:

  • type_string (String, nil) —

    Harmonized type string from the parser.

  • name (String, nil) (defaults to: nil) —

    Monograph name (for name-based heuristics, deferred).

Returns:

  • (Class) —

    a subclass of Openphar::Models::JP::Monograph
