Public abstract interface FilterConfig

public abstract interface FilterConfig
what is this class actually . is it abstract class or interface?

An interface is always totally abstract ???Yes, all methods of an interface can be declared abstract but you don't have to because that's understood. An interface can carry no implementation. It contains only abstract methods and static variables. Also everything is automatically public so you don't have to point that out specifically.

  • Public abstract interface I{

    Interface are totally abstract by default so what is the need of abstract in
    public abstract interface I{
    ........}does this have any functionality........

    I believe it's entirely redundant.
    I believe that the "public" part is also entirely
    redundant.
    Check the language spec to be sure.Abstract is redundant--all interfaces and their methods are implicitly abstract.
    Public is redundant for interface methods--they're always public--but not for the interface itself. You can have package-scope interfaces. Not sure about private ones.

    What is an "abstract interface" ?

    All interface's are implicitly abstract so declaring an interface abstract is a bit pointless.

  • Method in abstract interface

    Suppose I have an abstract interface which has one method:
    public abstract interface IParent {
      public void setSignal(int signal);
    }And I have a concrete interface inherited from IParent which also have one method:
    public interface IChild extends IParent {
      public void setSpeed(int speed);
    }If I define a class which implements IChild it only asks me to implement setSpeed method.
    public class Test implements IChild {
    }Why it does not ask me to implement setSignal method of IParent interface?

    Suppose I have an abstract interface which has one method:
    Every interface is implicitly abstract.
    public void setSignal(int signal);
    Every method declaration in the body of an interface is implicitly public.
    And I have a concrete interface inherited from IParent which also have one method:
    Every interface is implicitly abstract.
    If I define a class which implements IChild it only asks me to implement setSpeed method.'It' being what?
    Why it does not ask me to implement setSignal method of IParent interface?I have no idea what 'it' you're talking about, but the Test class will not compile.

  • Interface v/s Abstract Interface

    I am bit confused in one place during the declaration of Interface. as you know I can define a Inteface in two way,
    a) public interface InterfaceTest {
         public void test();
    b) public abstract interface InterfaceTest {
         public abstract void test();
    In first case I declare a normal Interface and in second case done with a abstract keyword. Both are working in a same manner.
    But when Java allow us to declare it in two ways, the their must be a reason behind the scene.
    Can you explain me the reason behind this tow type of Interface declaration

    Can you explain me the reason behind this tow type of Interface declaration JLS says:
    Every interface is implicitly abstract. This modifier is obsolete and should not be used in new programs.

  • Use of abstract interface

    I have a series of questions....... Go through.
    What is the use of abstract interface in java ?
    What is the use of static object in java ?
    What is the use of abstract key word to variables ?
    Object reference passed to method are final. Can ' t we change it ?

    class Testing {
         int i;
    public class RefFinal {
       public static void f ( Testing t1, Testing t2) {
           Testing temp;
           temp=t1;
           t1=t2;
           t2=temp;
           System.out.println("value of i in t1 =" +t1.i);
           System.out.println("value of i in t2 =" +t2.i);

  • Internal class implementing interface extending abstract interface :P

    Confused ha? Yeah me too. RIght here it goes.
    Theres an abstract interface (abstractIFace) that has for example method1() method2() and method3(). There are two other interfaces iFace1 and iFace2 that extend abstractIFace. Still with me? :P iFace1 only uses method2() whereas iFace2 uses method1(), method2() and method3(). Internal classes implementing these are then used. The reason is so that when returning an object one method can be used that will return different types of objects. But this doesnt work. It says that all the classes in the abstractIFace must be used/implemented but I only want method2() in iFace1 and all in iFace2.
    Just say what the f*ck if this is too confusing cos i think it is and i did a crap job explaining!! :P

    public interface IFace {
        void method1();
        void method2();
        void method3();
    public class Test {
        private static class Class1 implements IFace {
            public void method1() {
                System.out.println("method1");
            public void method2() {
                System.out.println("method2");
            public void method3() {
                System.out.println("method3");
        private static class Class2 implements IFace {
            public void method1() {
                throw new UnsupportedOperationException();
            public void method2() {
                System.out.println("method2");
            public void method3() {
                throw new UnsupportedOperationException();
        public static IFace createObject(boolean flag) {
            return flag ? (IFace) new Class1() : new Class2();
    }

  • Java.lang.AssertionError: Can not find generic method public abstract

    I just downloaded the JDev 11g and trying to test the JEE web app. Below is my install:

    JEE Web Project
    EJB 3.0
    Steps taken:
    1. Created an entity bean from a table.

    3. Create sample Java client to use the facade (Right-click on the session facade, and choose New sample Java Client from the context menu)
    4. Run the session facade
    5. Run the Java client
    I got the following error.
    java.lang.AssertionError: Can not find generic method public abstract java.util.List<com.oracle.orm.model.ejb.persistence.Hosttags> queryHosttagsFindAll() in EJB Object
    I checked the methods in the beans and interfaces, they are all there. Any idea?
    Thanks.

    I have a customer that has this problem.
    We wrote me that:
    we got a java.lang.NoSuchMethodException while the method exist even in the generated (by WLS) stub.
    when we change the interface by putting a "list" instead of list <> then it works.
    hope it can help, but should be great know why.

  • Public API/Interface name to import the payment information against invoice

    Hi,
    I want to get the Oracle supported Public API/Interface name to import the payment information against invoices(because there is a need to importing payment data against closed invoices from 11.5.5 to R12). Since I am not getting any standard oracle supported method, I am using the API AP_PAY_INVOICE_PKG.AP_PAY_INVOICE but while running it I am getting the following error:-
    Payment API Error =ORA-20001: APP-SQLAP-10000: ORA-28115: policy with check option violation
    occurred in
    AP_AIP_TABLE_HANDLER_PKG.Insert_Row <-AP_PAY_INVOICE_PKG.ap_pay_insert_invoice_payments<-AP_PAY_INVOICE_PKG.ap_pay_invoice<-.
    Regards,

    The below query will meet your requirement, but payment amount won't matches with some cases see below .
    1) Check Payment/EFT Payment for more than one invoice we will pay that time invoice amount is
    not equal to payment amount, Payment amount is greater than Invoice Amount.  This will be controlled in Report level.
    if you develop report using this query, there you can control this issue.
    SELECT aia.vendor_id, aps.vendor_name, aia.invoice_id, aia.invoice_num,
           aia.invoice_date, aia.invoice_currency_code, aia.payment_currency_code,

  • Difference between abstract interface and normal interface

    Hello Friends,
    What is the Difference between abstract interface and normal interface?....

    What is the Difference between abstract interface and
    normal interface?....The difference is that you didn't follow convention in the first case. All interfaces are implicitly abstract so you don't have to declare them as such.

  • BPM, abstract interface unavailable

    Hello,
    I want to build a business process. Therefore I need some container elements. One container element has the type abstract interface. The message interface is defined in some namespace of some software component. But unfortunately I can't select this message interface in the dialog. Of course I have already activated my change list. I also refreshed the CPA cache, but this doesn't help a lot. What can I do in order to see this abstract interface.
    Thank you very much,
    Oliver

    Hallo Oliver,
    XI currently only allows BPM to use interfaces within the same software component or within a software component with which you have a based on relationship defined.
    I think, that this does not make too much sense, but that's the answer we got to an according OSS message.
    Best Regards

  • BPM Abstract Interface for IDOC?

    Hi all,
    I am doing an IDOC XI File scenario with BPM.
    I have created an Inbound Asynchronous and an Abstract Interface for the LEGACY SYSTEM(Target Message).
    I didn't create any Abstract interface for the IDOC(Source message).
    I am getting this error:
    <b>"Expression must return the interface type DEBMAS.DEBMAS06.DEBMAS06".</b>
    Do I need to create an Abstarct Interface for the IDOC?
    According to the above error, BPM is expecting an ABSTRACT INTERFACE Type for the IDOC.
    Experts need help from you.
    Thank you,
    Joslyn.

    That mapping is an dummy mapping between Idoc to Abstract Idoc Type. Here Sender Idoc Interface is mapped with Reciever Abstract Idoc interface.
    So inside the BPM, Abstract Idoc interface acts as a Container variable to collect the idocs.
    For simplicity-for collection of idocs
    You can see, BPMPatterns from the SAP BASIS Software Component in your XI Repository.

  • Transformation Abstract interface

    Hello , i am using a message transformation step in BPM where msg 1 thats input for this map is xml and output is being mapped to a IDOC.
    Now since in BPM i have to use abstract interfaces and how can i relate this abstract interface in transformation step with the IDOC. Can i create the abstract interface and then relate it to IDOC and use it in BPM ?
    Krishna

    Hi Krishna ,
    in message mapping just - drag and drop - the IDOC_type from your node "imported objects"
    Thats all.

  • Copy value of container (abstract interface) to an other container

    Hello,
    Is it possible to copy the value of an container (abstract interface) in BPM to an other container (abstract interface)?
    Thanks and regards
    Verena

    Hi Verena,
    If you have the entire msg that you want to want in a container then you can probably use APPEND in container operation.
    But if your msg is a part of an intermediate strucure like the one i showed in my previous posts, then you Have to use Mapping in a BPM Transformation step for the simple reason that you cannot change a message by using a container operation.
