Discussion

Converts a string representation to a typed value. This is used during deserialisation (e.g., from XMI or JSON) to convert attribute values from strings to their proper Swift types.

Supported Conversions

EString → String
EInt → Int
EBoolean → Bool
EFloat → Float
EDouble → Double
Custom data types (uses instanceClassName for reflection)

Example

let intType = EDataType(name: "EInt")
if let value = factory.createFromString(intType, "42") as? Int {
    print("Parsed: \(value)")  // 42
}
