Class
AQLExecutionContext
Execution context for Acceleo Query Language (AQL) expressions.
@MainActor final class AQLExecutionContextOverview
The AQL execution context manages variables, model access, and the delegation of computation to the underlying ECoreExecutionEngine. AQL focuses on efficient querying and navigation without side effects.
Architecture
-
Coordination: Handled on
@MainActor. -
Computation: Delegated to
ECoreExecutionEngineactor.
Example Usage
let engine = ECoreExecutionEngine(...)
let context = AQLExecutionContext(executionEngine: engine)
context.setVariable("self", value: myObject)
let result = try await expression.evaluate(in: context)Topics
Initializers
?
init(executionEngine:)
Creates a new AQL execution context.
