IModel

protocol IModel : Sendable

Overview

The IModel interface provides a framework-agnostic way to access and manipulate models, similar to Eclipse ATL’s IModel. This abstraction allows transformation engines to work with different modelling frameworks whilst maintaining consistent semantics.

Design Principles

• Framework Independence: Abstract from specific ECore implementation details

• Read/Write Control: Clear separation between source (read-only) and target (writable) models

• Type Safety: Maintain Swift’s type system whilst providing dynamic model access

• Thread Safety: All operations must be safe for concurrent access

Usage Example

let sourceModel: IModel = EcoreModel(resource: sourceResource, isTarget: false)
let targetModel: IModel = EcoreModel(resource: targetResource, isTarget: true)

let elements = sourceModel.getElementsByType(personClass)
let newPerson = try targetModel.createElement(ofType: personClass)
