DynamicEObject

struct DynamicEObject

Overview

This type provides a basic object implementation that can represent instances of any EClass. Feature values are stored in a dictionary and accessed reflectively.

Usage

In a complete EMF implementation, code generation would create specific typed classes for each EClass. This dynamic implementation serves as a fallback and for testing.

Example

let employeeClass = EClass(name: "Employee")
let nameAttr = EAttribute(name: "name", eType: stringType)

var employee = DynamicEObject(eClass: employeeClass)
employee.eSet(nameAttr, "Alice")

if let name = employee.eGet(nameAttr) as? EString {
    print("Employee name: \(name)")
}

JSON Serialization

DynamicEObject conforms to Codable and can be serialized to/from JSON. The JSON format matches pyecore’s format:

{
  "eClass": "http://package.uri#//ClassName",
  "attributeName": "value",
  "referenceName": { ... }
}
