Module: Ea::Svg::EaEmitter::Element::HeaderLinePipeline

Defined in:
lib/ea/svg/ea_emitter/element/header_line_pipeline.rb

Overview

OCP-friendly header line pipeline. Each contributor is a stateless provider that appends 0+ lines to the output. New behaviors add a new provider to PROVIDERS without modifying existing ones.

Context (Struct) carries everything a provider might need:

classifier, diagram_package_id, visually_nested,
umldi_keyword, bounds_width, font_size,
off_canvas_parent_name

Each provider implements:

def self.call(context)  →  Array<[[text, style], ...]>
