ATLStatement

protocol ATLStatement : Sendable

Overview

ATL statements provide imperative control flow within the otherwise declarative ATL framework. They are primarily used within called rules to perform sequential operations that cannot be expressed through pattern-based transformations.

Overview

Statement types include:

• Assignment statements: Variable and property assignments

• Conditional statements: If-then-else control structures

• Loop statements: Iteration over collections

• Expression statements: Standalone expression evaluation

Implementation Notes

Statements maintain Sendable conformance to enable safe concurrent execution within ATL virtual machines operating across multiple actors.
