ECoreExecutionEngine

actor ECoreExecutionEngine

Overview

The execution engine serves as the central coordinator for model operations, providing thread-safe access to navigation, querying, and expression evaluation. It maintains performance optimisations through caching whilst ensuring consistency across concurrent operations.

Architecture

The engine follows a layered approach:

• Model Access: Unified interface to source and target models

• Navigation: Property traversal with caching and type checking

• Expression Evaluation: OCL-like expression processing

• Type Resolution: Dynamic type lookup and validation

• Performance: Intelligent caching and batch operations

Example Usage

let engine = ECoreExecutionEngine(models: [
    "source": sourceModel,
    "target": targetModel
])

let result = try await engine.navigate(from: person, property: "name")
let instances = engine.allInstancesOf(personClass)
