  • Define pointcut to capture an interface but not parent or sub interfaces

    - by mR_fr0g
    I was wondering how to define a pointcut in aspecJ the captures any method of an interface but not the methods of any parent or sub interface. pubic interface A { void methodA(); } pubic interface B extends A { void methodB(); } pubic interface C extends B { void methodC(); } I would like a poincut that only catches methodB() and not methodA() or methodC(). Is there any way i can do this in a general way without listing all the sub and super interfaces in the pointcut?

  • Expanding collapsed code in Eclipse IDE

    - by rabin
    Instead of going through each (+) sign at the left and clicking them to expand the collapsed code snippets, is there a shortcut or menu item (I couldn't find it, VS has that) to expand all the collapsed code/comments at once? Thanks.

  • Searching major search engines with text such as <%#

    - by Daniel Dyson
    If I type '<%# vs <%"' into any of the major search engines, everything is stripped out except the 'vs'. I understand why they do this. I would just like to know if anyone knows of a way to escape illegal characters so that they are searched properly. I know this is not strictly a programming question, but it is relevant.

  • How to implement a tiered "selection tree" in Swing? (Or: is there an existing implementation?)

    - by Sbodd
    I need a Swing component that will let me display a tree-structured list of items, and allow the user to select or de-select an arbitrary subset of those items, with the ability to select or deselect an entire subtree's worth of components by picking that subtree's parent. (Basically, something similar to the Eclipse "Export JAR file's" dialog (an image of the relevant dialog is here - I basically want the "Select resources to export" component, but for a Swing application.) I know I can do this by creating a custom TreeCellRenderer, a custom TreeCellEditor, and a custom TreeModel - but that seems like an awful lot of work. Are there any good off-the-shelf implementations that I can use? Thanks!

  • Why is this condition never satisfied ?

    - by Patrick
    I don't know why this condition is never satisfied: I'm comparing two ArrayList values, and it is always false. if ( (Integer) results.get(rank) == (Integer) experts.get(j)) I'm debugging and I have exactly the same 2 values: 3043 and 3043 However it doesn't work. thanks

  • Works on development server but it doesn't on Google App Engine (Sessions).

    - by grep
    Hi, I have this code that works just fine on the development server but when I deploy the application, the session isn't created. What am I doing wrong? HttpSession session = req.getSession(true); session.setAttribute("loggedIn", new String("true")); Edit: The sessions are enabled. What I realized now is that the _ah_SESSION variable is not being created, not even on the development server (although it works).

    - by user3461659
    I am working in Android Studio and am trying to get the ID of the selected radio button and then store the ID in a string. Is this possible? I have tried replacing the .getText() method below with .getId() but it wont let me store it as a string: RadioGroup radioGroup = (RadioGroup) findViewById(R.id.radioGroup); radioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() { @Override public void onCheckedChanged(RadioGroup radioGroup, int checkedId) { RadioButton checkedRadioButton = (RadioButton) findViewById(checkedId); String text = checkedRadioButton.getText().toString(); Toast.makeText(getApplicationContext(), text, Toast.LENGTH_SHORT).show(); } });

  • trying to switch beginning of an array with another

    - by user1874574
    I have a problem where i am trying to swap two arrays so that they switch beginnings. example: array 1 = (1,2,3,4,5,6,7,8) and array 2 = (11,12,13,14,15,16,17,18) i want to end up with the first array being (11,12,13,14,5,6,7,8) and i want the second array to be (1,2,3,4,15,16,17,18) but for some reason i end up with 1=(11,12,13,14,5,6,7,8) and 2=(11,12,13,14,15,16,17,18) my code is provided below, what am i doing wrong? public static void Mutate(Genetic lowest, Genetic secondLowest) { int halfway = (lowest.getPopulation().length)/2; int[] one = lowest.getPopulation(); int[] two = secondLowest.getPopulation(); int[] temp = secondLowest.getPopulation(); int[] temp2 = lowest.getPopulation(); for(int i = 0; i < halfway; i++){ temp[i] = one[i]; } lowest.setPopulation(temp); for(int i = 0; i < lowest.getPopulation().length; i++){ System.out.print(temp[i]); } System.out.println(); for(int i = 0; i < halfway; i++){ temp2[i] = two[i]; } for(int i = 0; i < lowest.getPopulation().length; i++){ System.out.print(temp2[i]); } }

  • Traversing ORM relationships returns duplicate results

    - by NKing253
    I have 4 tables -- store, catalog_galleries, catalog_images, and catalog_financials. When I traverse the relationship from store --> catalog_galleries --> catalog_images in other words: store.getCatalogGallery().getCatalogImages() I get duplicate records. Does anyone know what could be the cause of this? Any suggestions on where to look? The store table has a OneToOne relationship with catalog_galleries which in turn has a OneToMany relationship with catalog_images and an eager fetch type. The store table also has a OneToMany relationship with catalog_financials.

  • Are Interfaces "Object"?

    - by PrashantGupta
    package inheritance; class A{ public String display(){ return "This is A!"; } } interface Workable{ public String work(); } class B extends A implements Workable{ public String work(){ return "B is working!"; } } public class TestInterfaceObject{ public static void main(String... args){ B obj=new B(); Workable w=obj; //System.out.println(w.work()); //invoking work method on Workable type reference System.out.println(w.display()); //invoking display method on Workable type reference //System.out.println(w.hashCode()); // invoking Object's hashCode method on Workable type reference } } As we know that methods which can be invoked depend upon the type of the reference variable on which we are going to invoke. Here, in the code, work() method was invoked on "w" reference (which is Workable type) so method invoking will compile successfully. Then, display() method is invoked on "w" which yields a compilation error which says display method was not found, quite obvious as Workable doesn't know about it. Then we try to invoke the Object class's method i.e. hashCode() which yields a successful compilation and execution. How is it possible? Any logical explanation?

  • Is this possible?

    - by Stud33
    I want to incorporate some Accelerometer code into a Android application im working and want to see if this is possible. Basically what I need is for the code to detect car acceleration motion. I am not wanting to determine speed with the code but just distinguish if the phone is in a car and has accelerated motion (Hence the car is moving for the first time). I have gone through many different accelerometer applications to see if this motion produces a viable profile to go off of and it appears it does. Just looking for something that popups a "Hello World" dialog when it detects your in the car and its moving for the first time down the street. Any help would be appreciated and a simple yes or no its possible would work. I would also be interested in compensating anyone that is capable of doing this as well. I need this done like yesterday so please let me know. Thank You, JTW
