Extracting properties using reflect()

mirror.swift

struct Properties {
    // someday soon these can be private
    var _name: String, _nameModificationDate: Int
    var _shape: String, _shapeModificationDate: Int
    
    init(name: String, nameModificationDate: Int,
        shape: String, shapeModificationDate: Int) {
            self._name = name
            self._nameModificationDate = nameModificationDate
            self._shape = shape
            self._shapeModificationDate = shapeModificationDate
    }
    
    func name()->String { return _name }
    func nameModificationDate()->Int { return _nameModificationDate }
    
    func shape()->String { return _shape }
    func shapeModificationDate()->Int { return _shapeModificationDate }
}


let p = Properties(name: "Fred", nameModificationDate: 1, shape: "Bob", shapeModificationDate: 2)

let mirror = reflect(p)

for i in 0..<mirror.count {
    let (name, element) = mirror[i]
    println("\(name) = \(element.value), type \(element.valueType)")
}


// prints out
// _name = Fred, type Swift.String
// _nameModificationDate = 1, type Swift.Int
// _shape = Bob, type Swift.String
// _shapeModificationDate = 2, type Swift.Int
