Module: Ea::Svg::EaEmitter::Compartment::PackageContents

Defined in:
lib/ea/svg/ea_emitter/compartment/package_contents.rb

Overview

Package-contents compartment. Renders the package's child classifiers and sub-packages as a list of "+ Name" rows in the body, matching EA's package-on-diagram rendering. Each row also draws a small per-type icon to the left of the text (Enumeration gets a list-style icon; other classifiers get the "folded paper" silhouette).
