How to put constructors and methods in the same list?

[mashalahmad]

I want to save methods and constructors of any class under one list.
This is sample of what Im doing
private static List<CtMethod> GetMethodsnConstructor(CtModel model){ List> Allconstructornmethods = new ArrayList<CtMethod>(); List> constructors= model.getElements(new TypeFilter<CtConstructor>(CtConstructor.class)); Allconstructornmethods = model.getElements(new TypeFilter>(CtMethod.class));
for(CtConstructor<?> constructor: constructors)
{
if(!(constructor.isImplicit())) {

		  Allconstructornmethods.add((CtMethod<?>)constructor);
	  }
  }
  return Allconstructornmethods;

}

Im saving it to Allconstructornmethods which is CtMethod Type list and getting an error at
Allconstructornmethods.add((CtMethod<?>)constructor);
as error says I canot caste constructor to methods . is there any other way ?
thanks

Both CtConstructor and CtMethod are CtExecutable so you could store them in a List<CtExecutable>.

[mashalahmad]

but how can I check which executable is constructor and which one is method?

[pvojtechovsky]

if (exec instanceof CtMethod) {
//it is method
} else {
//it is constructor
}

hey thanks
one more question. is it possible to built model of a class multiple times?
like I have a class which is changed multiple time mainly class name is same (similarly some methods) but some new code is added. Im trying to get ast of that class but im getting error model already built
im doing it this way

`
String directory = "path/to/directory";

		  		 try (Stream<Path> paths = Files.walk(Paths.get(directory))) {					
		  			 paths.skip(1)
		  			 	 .forEach(s->{
				  			 	Path path1 = Paths.get(s.toString());	 
				  				launcher.addInputResource(path1.toString()); 			  				
								CtModel model=launcher.buildModel();
								// using this model to do some calculations
		  			 	 		}); 
		  			 
				} catch (IOException e) {
				    e.printStackTrace();
				}  `

now directory has multiple version of same class. getting this error
Exception in thread "main" spoon.SpoonException: Model already built

You can use this just before building your model again:

model.setBuildModelIsFinished(false);

See:

spoon/src/main/java/spoon/reflect/CtModel.java

Line 72 in 96d3150

<T extends CtModel> T setBuildModelIsFinished(boolean buildModelFinished);

I set it but still i get the same error
Exception in thread "main" spoon.compiler.ModelBuildingException: The type RoomItems is already defined

Yes, this solution only works if you build new sources, not different versions of the same sources.
For what you want to do I think you should use the IncrementalLauncher (see https://github.com/INRIA/spoon/blob/master/src/main/java/spoon/IncrementalLauncher.java) It should allow you to build your model incrementally. @Egor18 might give you some help on this part.
