While trying and playing around with Typhoon DI, I realized that LazySingleton scope is not working as expected meaning lazy properties are injected even before they are used. Being more concrete I created a TyphoonAssembly as follow :
public class AppAssembly : TyphoonAssembly {
public dynamic func knight() -> AnyObject{
return TyphoonDefinition.withClass(Knight.self){
(definition) in
definition.injectProperty("name", with: "Dragon")
definition.injectProperty("horse")
definition.scope = TyphoonScope.LazySingleton
}
}
public dynamic func horse() -> AnyObject{
return TyphoonDefinition.withClass(Horse.self){
(definition) in
definition.injectProperty("color", with: "red")
definition.scope = TyphoonScope.LazySingleton
}
}
}
where Knight is NSObject and has validateProperties function
class Knight:NSObject {
var name:String?
var horse: Horse?
func validateProperties(){
if name != nil{
println("Name not nil")
}
if horse != nil{
println("Horse not nil")
}
}
}
After activating assembly and getting knight from it, calling validateProperties function always print Name not nil and Horse not nil even these properties are never used in my code. Am I missing something here or simply lazy injection does not work same as Swift lazy stored properties do?
