Overview

Builds the text representation of a single property line for the attribute compartment. Encapsulates the four EA rendering rules:

1. Visibility marker (+, -, #, ~).
2. Namespace prefix on properties inherited from a
 classifier in a different package ("core::mimeType").
3. Primitive type name stripping ("xs::double" → "double").
4. Multiplicity shorthand ("[2..2]" → "[2]") and
 `{ordered}` modifier.

Stateless: each call returns a fresh line String. Pass a Lookup to enable cross-classifier resolution (namespace prefix). Without a lookup, the line is rendered as-is (backwards-compatible).

Constant Summary collapse

PRIMITIVE_TYPES =

XSD primitive types whose namespace prefix EA drops in the rendered attribute line. The full set is not yet reverse-engineered — leave empty for now so we never wrongly strip a prefix. TODO-D 47 will populate this once verified per-diagram.

Constructor Details

#initialize(property, host: nil, lookup: nil) ⇒ AttributeLineBuilder

property - the Ea::Model::Property to render host - the Ea::Model::Classifier whose compartment we're rendering (determines "inherited" status) lookup - object responding to #call(id) -> Classifier used to resolve the property's declaring classifier (defaults to no lookup).
