Execute nested method calls from Method object

I need to make a call to following method -

testObj.getA().getB().getC().getD();

Above, testObj.getA() returns object A which has a method getB(), which returns object B that has method getC(), which returns object C and it has method getD().

How can I invoke it using reflection? If I try Method object as following -

Method m = testObj.getClass().getMethod("getA().getB().getC().getD(), null));

Above fails saying the method is not found. Any suggestions?

Get all object with particular trait in scala

Given this code:

trait A[T]{
  val name: String
  val inner: T
}

object B extends A[String]{
  val name = "objB"
  val inner = "5"
}

object C extends A[Int]{
  val name = "objC"
  val inner = 5
}

object D{
  val name = "objD"
}

I want to get all inheritors of trait A:

Map("objB" -> B, "objC" -> C)

Is it possible with reflection? Can this map be generated at compile time?

How to call setOnInstalledPackaged always

I have this code but the method packageInstalled It does not work when I update some apks, it is as if it were never called.

        ApplicationManager am;
        am = new ApplicationManager(contexto);
        am.setOnInstalledPackaged(new OnInstalledPackaged() {

            public void packageInstalled(String packagName, int returnCode) 
            {
                  if (returnCode == ApplicationManager.INSTALL_SUCCEEDED)
                {
                    // CODE
                }
                 else
                 {
                    // CODE
                 }
            }

        });

Final self class for generics, in method signature, in Swift

I have a BaseObject model that defines common behaviour I want to share across all my data entities. It has a method like this:

class BaseObject {
    static func fetch(block: ((Results<BaseObject>) -> Void)) {
        // networking code here
    }
}

Naturally, I need the signature of this method be dynamic enough so that a model of class Products

class Products: BaseObject { //...

yields a Results<Products> list instead of Results<BaseObject>. I don't want to re-implement the fetch method in every subclass, because, save for the exact final subclass name used in the body and in the signature, it would be identical.

I cannot use Self:

Do I have any options at all?

java : dynamic code creation from database content using reflection

I am trying to replace static code in my application using reflection. Object relational mappers need to use reflection to instantiate objects from databases without knowing in advance what objects they're going to use. Can I find some examples and information regarding this as I am naive(not worked before) about using reflection. Any help is appreciated.

PS: I don't have working knowledge of reflection concepts, went through some documentations.

Android make higher level API call without targeting a high level SDK

I need to dim the navigation bar in my app targeting API 10. I cannot target 14, capable of that, because my app starts behaving too slow after that single change. Is there another way to do that? i.e. reflection, or using an external helper app as a service, Or maybe something else?

asp.net dnxcore50 load assembly by file path

How do you load an assembly in asp.net under dnxcore50 (DNX Core 5.0)?

I have a Lib/FooLibrary.dll path in the directory where my asp.net 5 app lives, but i cannot seem to find any way of loading the assembly via reflection

My ultimate goal is to use reflection to load the assembly and get some MethodInfos in order to do some light-weight code generation.
