Class: Coradoc::Introspection::ElementCounter

Inherits:
Visitor::Base show all
Defined in:
lib/coradoc/introspection/element_counter.rb

Overview

Visitor that walks a document and counts each CoreModel node by its type key. Used by Introspection.count_element_types to back the Coradoc.document_stats API.

Typed StructuralElement / Block nodes are counted under their element_type (semantic identity). Other nodes fall back to a snake_case rendering of their class name.
