Interface Variable

Hi,
can somebode explain how succesfully create a bpm block witch Modus ForEach?
I have a multipleLine element which collects messages, now i want to send these messages seperate.
My idea was to create a block witch Modus ForEach and set the current Line property for sending with a end condition.
My Problem is that i cant set the current Line Property. The editor  requeriers at this property a Interface variable.. but i cant chosse anything, its deaktive!
Can somebody give me a hint how to create a Interface Variable ?
regards

Hi ,
You will have to create two interface variables .  Create one variable withoption multiline checked and another with unchecked . make sure the one which you define is of type multiline should be of of type which has occurance 0..unbound . Also make sure in your message type you have a variable which contains the total number of records/instances in multiline elements.
Then in your ForEach Block select the interface variable  which has only one occurance ( multiline flag is unchecked) as currentline element . This  loop will get executed till the counter = total number of records/instances in multiline elements

  • About Interface variables...

    Hello everybody.
    I am new to Java so please don't mind if my question looks trivial !
    I would like to know why interface variables can be static but interface methods cannot be static ?
    regards,
    Naveen.

    But its still not clear, why Interface variables need to be constants ? Why cant they be assigned values by the implementing classes ? Does it have to do with optimization ?because they were designed to be like that ; if you want fields to be variable, then use abstract class ; a nice example of constants that could be contained in an interface is the value of PI
    the value of PI is not supposed to change in the time, and making it variable could lead to really serious problems in the program, if a class alter its value

  • Report Report Interface Variable Values Transport

    Hi,
    I'm trying to use the report report interface for passing variable values.
    How can I pass variable values of the sender query into the reciever report?
    An example:
    - I've used the 0CALYEAR time characteristic infoobject with a suitable input variable in the sender query.
    - The sender query is used in the report (web template)
    for a chart in away that the x axis peresenting the years (is the 0CALYEAR).
    - I'm trying to pass the mentioned variable input - and no the selected year from the chart (by generically), into the reciever report queries which contained the 0CALYEAR infoobject.

    DEar Shani,
    Did you check the assignment details onceagain on the 0CALYEAR in RSBBS transaction..

  • Interface variable like in Serializable

    Hi,
    I'm searching for a way to declare a non-static variable in an interface...
    I know, that simply saying "public final int foo = 0;" doesn't work... ;-)
    But somehow, it must be possible to do something like that, at least Serializable does this!
    Does anybody know how this Interface work internally or how it could work?
    nafur

    Anyway, such a functionality must be possible (probably not via an interface but via an abstract class?) as Serializable offers that.No, it doesn't. Serializable is a marker interface. It provides no functionality whatsoever.
    I want a Interface or a superclass or anything that requires my subclass to define some variable.You'll want to rethink your design, as what you seek is not possible. Think in terms of interface as a contract that requires behavior, not data.
    How does Serializable does that?It doesn't.

  • FOREACH scenario : usage of Receiver or Interface variable

    Hi fellow ccBPMers
    I have scenario with flat files that must be read and split up into individual files.
    First file is a Header Flat File containing 4 Header records
    A xxxxxxxxxxxx
    B xxxxxxxxxxxx
    C xxxxxxxxxxxx
    D xxxxxxxxxxxx
    Second file is a Detail Flat File containing the associate Detail records
    A Line 1
    A Line 2
    B Line 1
    B Line 2
    B Line 3
    C Line 1
    D Line 1
    D Line 2
    D Line 3
    D Line 4
    This must be merged and produce another 4 files (they will be IDOCS)
    File1 :  A xxxxxxxxxxxx  with a Line 1 and 2
    File2:   B xxxxxxxxxxxx  with Line 1 and 2
    File3 :  C xxxxxxxxxxxx  with Line 1
    File4 :  D xxxxxxxxxxxx  Line 1, 2, 3 and 4
    I have considered the usage of a Block FOREACH to process a multiline container that I have set up that should contain a record for each grouping of lines.
    Now for the FOREACH the multiline element lets me choose either a Receivers (from a ReceiverDetermination step)
    OR seems that also choose an instance variable of my collected group of records. 
    Question then is :  If I choose the instance variable,  will the FOREACH simply loop through each collected group of records and send them one at a time  (if so I would not need the determine receivers step - as suggested by saphelp doco).
    I'd appreciate it if somebody could consider the scenario and provide an opinion.  Points awarded of course !
    Thanks

    Here is a description of my Integration Process.
    It has a FORK with 2 steps.  step1 to Receive a BODY and Collect into multiline HeaderContainer
    and step 2 to Receive a HEADER and Collect into multiline BodyContainer
    next has a TRANSFORMATION with source being the HeaderContainer and the BodyContainer and target CollectedHeaderandBody
    next a FOREACH Block has multiline element of CollectedHeaderandBody and current line as a CollectedLine (of the CollectedHeaderandBody)
      within the FOREACH block it will SEND the CollectedLine.
    Does that seem correct ?

  • Interface variable value

    Hi,
    Can some body will help me to understand the below code and explain the output or flow of this -
    public class Test implements A, B, C {
        public static void main(String[] args) {
            System.out.println("A = " + A);
    interface A extends B {
        public static final int A = 2 * B;
    interface B {
        public static final int B = C.C + 1;
    interface C extends A {
        public static final int C = A + 2;
    }output :
    A = 6I am not getting how it has printed the output value.
    Thanks

    Until initialization completes A has a "value" of zero. A references B, which references C, which references the (uninitialized) A.
    We'll call uninitialized value of A a prime = A'
    We'll call the initialized value of A a double prime = A''
    A' = 0
    C = A' + 2 = 2
    B = C + 1 = 3
    A'' = B * 2 = 6The value that's printed is therefore 6. But to understand this in detail you must read the JLS. But it's a toy problem; you shouldn't have this sort of "loop" initialization in the first place and the first step to "debugging" it would be to eliminate it.

  • Variable scope within an interface and some questions

    I am creating a DataStorage interface with a member variable (can I call it a member variable when it is in an interface?) called dataObject. From what I remember, and what the compiler is telling me, the scope declarations "private," or "protected" can not be used on either methods or member variables in an interface.
    Now I have another class DataInput that implements DataStorage and I want to make the dataObject private and put in accessor methods to get to the dataObject. But I also remember reading something that said, during inheritance you can not make the scope of the method (and variable?) more narrow. Meaning if a method was defined as default in the parent class, the subclass can not override that method to give it private access all of a sudden.
    Now a couple of questions with this...does that rule only apply to subclassing (that is with extends) or does it also apply to implementing interfaces. Second question, I am pretty sure that rule applies to methods that are being overriden, but does it also apply to variables in an interface...because if that is the case, I can't re-declare the variable in the class that implements the interface to be private...and then there is no way to protect that variable.
    By the way I did re-declare the variable in the subclass (implementing class) and declared it as a private, and it works...but I'm still trying to figure out the general rule.

    well if the interface variables are implicitly public static final, how come I am able to re-declare the variable name within the class that implemented the interface.
    If for example in interface Car there is a variable color, how come in class Honda implements Car, I can redeclare the variable color, and give it public access. I thought final meant final, no redeclaring...but does that not hold for static variables?

  • "interface" datatype variable??

    While working with other people's Code I found the following:
    <code>
    public interface iMyClass //the interface
    public static string str = "";
    public void setStr(String sStr);
    </code>
    and in the same package:
    <code>
    public class MyClass //the class
    private iMyClass kuku; //a variable whose datatype is an interface
    private void setStr(iMyClass); //at the interface the param is a string
    // and here an interface!?
    </code>
    Is this possible?
    I have learned the following:
    KEYWORD: interface

    which can later be provided by other (not necessarily subclass) classes.

    OK Dorceon, you are right.
    But I found the following:

    just to use the static members of the interface in the class functions this way:

    why to declare the variable kuku?
    can't I reach the interface variables this way?:

  • Same interface name in alert for the synchronous messages

    Dear Friends,
       I have configured the alert for my interfaces. In the container i have added the message id, sender interface and receiver interface variables. While the error occurs, the alert is getting triggered. But in the alert long text in both the sender and receiver interface the Same 'is_Update'(receiver interface)  is only coming.
    But in the case of asynchronous interface alerts the sender and receiver interface are coming correctly in the long text of the alert.
    Please tell me what might me the problem.
    Thanks and Regards

  • Not able to give multiline container variable in transformation step.

    Hello,
    I'm doing a simple collect pattern in BPM.
    I have three container variables, one- the source interface, second the multiline of source interface and third-the target interface.
    Now, i have block in which i have the exception and deadline steps and then a loop in which i have my receiver which collects the message and gives it to the container to keep it to the list. Outside the block i have my transformation step which takes the relevant interface mapping. When i try to give the multiline container variable the box turns red, but of give the normal source container variable it accepts it.
    If i do a check by F7, Expression must not return a multiline value.
    The scope of the container variables is maintained as Process.
    What could be wrong, please help.
    Thanks and regards,
    Akhil

    hi akhil,
    think in transformation it sees source messages and target messages.
    if u have n:1 scenario then n interfaces to one interface right
    thats is each interface will have one message type
    so if u are using interace mapping in transformation it is expecting n interface variables to one interface variable.
    it will display n source messages to one source message jsut check.
    so transformation step is expecting one n sub message types to be embedded in one message type
    <messages>
    <message 1>
    <meessage n>
    </messages>
    this one is mapped with one XML target messgae
    so if u have n different messages see that u compress them in to one message type like the above and give it in trasnformation step.
    if you have n different messages then u can alwasy go for n different interfaces to one single interface
    then u can see in tranformation step n diff source messages and one target message
    was just confused with reciever step which allows multiline receivers

  • Container Variables

    How to read the Container Varaibles or a Message Interface variable when BPM fails for example in Message Mapping for instance?
    Thanks

    Mohini,
    The container elements in the BPM can be accesed in any step of the BPM as long as they have been initialized.
    In your case, if your Mapping has an error, wrap the Transfromation step within a block and in the exception handling step, you will be able to use the Container variables defined and initialized before the exception occured including the source message to the mapping. Just use this Container element in any step including a Send Step.
    is this what you are looking at?

  • Container definition for Abstract Synchronus Interface

    I am trying the simple scenario where the bpm process consumes soap request message (opens S/A bridge). After it queries another web services and sends back synchronously soap response, closing S/A bridge.
    I've walked through different weblogs and forum posts but still not getting how the interface variables should be created in this case.
    All my abstract interfaces are synchronous, and container definition for category "Abstract type" is only for Asynchronous interfaces.
    Should I create two additional asynchronous interfaces with the same request/response message names to be able create interface variables?
    And if message names are different in both soap calls should I create 4?
    Thanks,
    Evgeni
    scenario is similar to the one described in the weblog https://www.sdn.sap.com/irj/sdn/weblogs?blog=/pub/wlg/1403 [original link is broken] [original link is broken] [original link is broken] [original link is broken] [original link is broken] [original link is broken] [original link is broken]
    but without call to the legacy system and instead of JDBC it is another webservice.

    Hi, thanks for replay,
    >So this Abstract interface is used in the Receive step of the BPM(opening of the Sync/Async Bridge).
    I've created Abs Sync interface and used it in the Receive step. My problem is I can not assign value to the Message Name in the step Properties.
    To assign value I need first create container. To create container I need provide Type, which can be selected from the list of the "Message interfaces". But the list displays only Async Abs interfaces not Sync. How I should create container for Sync Request message?
    Looking on the help link you provided. How I should create following:
    Container
       Request
         BpmPatternBridgeRequest
       Response
         BpmPatternBridgeResponse
    Kind regards,
    Evgeni.

  • OSB - How select variable used as request message in routing to buss. serv.

    I' modelling a message flow for a proxy service.
    Depending on the content of the incoming request message, a branch (conditional) is selected. In this branch the message needs to be routed to a business service.
    This business service has a different request message definition than the proxy service. Some kind of transformation is probably necessary. (not implemented yet)
    Question is how to select what variable structure (I've created a Service Interface variable for the business service) that'll be used when invoking the business service.
    Only thing I can select, is the service and the operation.
    How to continue?

    The payload for the business service needs to be in the *$body* variable. There are also other predefined variables like $header and $attachments that could make sense if your need to send SOAP Headers or attachments to the business service.

  • Class implementation for interface

    Edited by: chris_75 on Sep 7, 2010 4:22 PM

    Interfaces allow to implement highly scalable object oriented applications.
    Interface is a kind of a template for a real class which forces this class to implement methods defined in an interface.
    The main characteristics of an interfaces are:
    - they DO NOT contain any implementations (so there is nothing like INTERFACE ... IMPLEMENTATION - they have only DEFINITIONS - implementations are within classes)
    - they have only PUBLIC sections.
    Why we need an interface. The answer is simple:
    We want to handle some objects uniformly from one application compotent, whereas these objects may behave differently inside.
    Example:
    Let's say we need to build a sorting program for numbers.
    The program would have an interface variable L_RIF_SORTER of an interface LIF_SORTER. LIF_SORTER has a method definition SORT with an C_TAB changing parameter.
    Sorting application would call the sorting algorithm as follows:
    L_RIF_SORTER->SORT( CHANGING c_tab = l_tab ).
    Now is the main point:
    We want to have 2 kinds of sorting algorithms implemented, let's say BUBBLE SORT and QUICK SORT.
    To do so, we implement 2 classes: LCL_BUBBLE_SORT and LCL_QUICK_SORT.
    Both classes implement interface using the statment INTERFACES in a public section.
    The user would have to choose the algorithm from an input field. Depending on the content of this field the sorting application would instantiate one class or the other using the statement:
    CREATE OBJECT l_rif_sorter TYPE (variable_with_class_name).
    THis is the point where ABAP gets to know the real object and its type behind the interface.
    This approach is generally called the STRATEGY PATTERN. See Wikipedia for this.
    I hope I answered your question.

  • Do Java interfaces have automatic reference counting?

    I'm actually a Delphi developer trying to understand interfaces and I'm curious about the way Java implements them.
    Here is a simple Delphi psuedo-code snippet:
    var
    // interface variable
    Intf : IInterface;
    // object reference variable
    Car : TCar;
    begin
    // instantiate TCar
    Car := TCar.Create;
    // obtain IInterface interface for Car object
    Intf := Car; // the reference count for Car is now 1
    Intf :=Nil;
    // After setting Intf to nil, the reference count is decreased to 0 and Car is automatically freed.
    Car.Free; // EXCEPTION! Car was automatically freed because the only interface reference had a reference count of 0
    What would happen in Java with the above code?
    Does Java automatically reference count all objects with interfaces?
    I know Java reference counts all objects in general so they are automatically destroyed, but I'm trying to understand the difference in interface implementation.
    Thanks for any help!

    Thanks for the replies!
    Sorry about my confusion with Java...
    Does Java support interfaces? If so, can't you have a interface reference variable like I have in my Delphi code?
    Also, if Java does support interfaces, do they have any other purposes aside from creating a list of functions/methods that can be used as a contract to interact with an object?
    Interfaces seem really useful since you can have an IDriveable interface (for example), and any unrelated classes can implement it... (eg. TBoat class, TCar class, etc) even if the classes do not have a common ancestor class.
    However, in Delphi interfaces also automatically reference count so once you create an interface reference you have to be very careful so the interface doesn't automatically free the object it is pointing to...
