ATLModule

struct ATLModule

Overview

An ATL module is the root container for a transformation specification, containing source and target metamodels, helper functions, transformation rules, and module-level configuration. ATL modules define unidirectional transformations from source models to target models using declarative matched rules and imperative called rules.

Overview

ATL modules follow a structured approach to model transformation:

• Source models: Read-only input models conforming to source metamodels

• Target models: Write-only output models conforming to target metamodels

• Helpers: Reusable functions that extend OCL with custom operations

• Matched rules: Declarative transformation rules triggered automatically

• Called rules: Imperative transformation rules invoked explicitly

Example Usage

let module = ATLModule(
    name: "Families2Persons",
    sourceMetamodels: ["Families": familiesPackage],
    targetMetamodels: ["Persons": personsPackage],
    helpers: ["familyName": familyNameHelper],
    matchedRules: [member2MaleRule, member2FemaleRule]
)
