ATLResource

@MainActor final class ATLResource

Overview

ATLResource provides a container for ATL modules that integrates with the ECore resource framework. It enables loading and saving ATL modules in Eclipse ATL XMI format, supporting full roundtrip serialization.

Overview

ATL resources manage:

• ATL Modules: The transformation specification including rules, helpers, and queries

• Metamodel References: References to source and target metamodels (EPackages)

• XMI Serialization: Proper Eclipse ATL XMI format compliance

Architecture

ATLResource composes an ECore Resource actor for managing metamodel references while providing MainActor-isolated access to the ATL module. This design allows:

• Thread-safe metamodel management through the Resource actor

• Main-thread coordination for ATL module access

• Integration with ECore ResourceSet for cross-resource references

Example Usage

// Create a resource for an ATL module
let resource = ATLResource(uri: "file:///transformations/Book2Publication.atl")

// Load from XMI
try await resource.load()
if let module = resource.module {
    print("Loaded module: \(module.name)")
}

// Save to XMI
try await resource.save()
