Overview

Generates an XSD schema string from a parsed QEA model.

Uses ClassMapping to translate UML class names to GML types and NamespaceRegistry to declare target namespaces. Walks the model's classifiers and emits <xs:element> + <xs:complexType> pairs.

Both class_mapping and namespaces default to the EA-bundled GML fixtures when present, so callers can do Ea::Export::Xsd::Generator.call(model, target_namespace: ...) without manually loading XML fixtures.

Instance Method Details

#call(model, target_namespace:, prefix: "tns") ⇒ String

Generate an XSD schema for the given model.

Parameters:

  • model (#collections) —

    anything responding to #collections with a :packages and :objects collection (Ea::Qea::Database).

  • target_namespace (String) —

    XSD targetNamespace

  • prefix (String) (defaults to: "tns") —

    namespace prefix for the target

Returns:

  • (String) —

    serialized XSD
