Object Node created inside class Node

public static class Node
protected static final Node EXTERNAL= new Node();
Can somebody do this? Shouldn't you first define a class and then create an object of it?
Thanks

Can somebody do this? I suggest you try it and find out.
Shouldn't you first define a class and then create an object of it?Yes.
The class is created when you compile the code.
The object is created when you run the program.
So there is no problem.

  • Creating custom class instances for XML nodes

    Hi guys,
    I'm trying to load an external XML document in my application
    and create an instance of a custom class for each node in the XML
    based on the value of some of their elements. The instances created
    will eventually end up in a DataGrid by the way. The problem I'm
    having is there seems to be many ways of doing small parts of this
    and I have no idea how to make them all gel. Initially I'm using
    HTTPService to load the XML file but I've seen people just use an
    XML object. Then, after that, I initially set the loaded XML to an
    ArrayCollection but others have used XMLList or XMLListCollection.
    I've no idea what's the best way to do this.
    Eventually, when I've created all of these instances by
    looping over the XML and creating them how will I make them
    bindable to the data grid? I'm guessing I'll have to group them
    somehow...
    Any help would be greatly appreciated. Thanks

    Hey Tracy,
    That is exactly what I was talking about in a previous post
    you replied to
    http://www.adobe.com/cfusion/webforums/forum/messageview.cfm?catid=585&threadid=1344350
    Anyhow, Below is some code I created to do what your saying
    somewhat dynamically. The idea being you can have many different
    object types that you may want to populate with data from XML. In
    my case I am using e4x as the result type from my web services. At
    present I have about 6 different classes that call this function.
    I'd love to get some opinions on the function. Good bad or
    ???? Any improvements etc????

  • BRF+ Deleting functions within object nodes

    Hi Experts,
    We are a large FMCG company and are implementing SAP Master Data Governance module for managing our material master data.
    Hence, we have chosen BRF+ as the business rule engine to drive SAP MDG. SAP MDG version is EHP5
    To create a ruleset, I initially create an object node within the 'Trigger tab' in the catalog. This object node is created with a naming convention DERIVE_ENTITY_ATTRIBUTE. I have then successfully created a function within the object and defined a ruleset as well.
    Now if I delete the object node; it gets deleted from the trigger function tab. However if I create a new object node with a similar function, the system does not allow me to create the function as it throws a warning message stating that the function still exists.
    Hence I wanted to know HOW DO I DELETE THE FUNCTION if the Object node for that function has already been deleted?
    Is there any option to search the function and delete it?
    Thanks in advance

    Hi Carsten,
    Where do you actually restore an object though?  I don't see a button on the UI. 
    I have deleted an object by mistake, but since I don't have versioning turned on I cannot do a version restore.  However I can still see the deleted object since it's only logically deleted?
    If you do not have versioning turned on is it then impossible to restore?
    Thanks,
    Lee

  • Unable to expand table (or 'any' object) node - permissions issue?

    I am the dba for a database and hence have access to the system user. When I connect to the db through SQL Developer, I can expand the table node under any user and list tables. As I can with any object node.
    I now want to create an admin user that has restricted capabilities, one of which will be to view objects, such as tables etc..
    (I will ultimately do this via a role to allow multiple users to have the admin capabilities, but for now have just created an admin_user userid).
    However, when I connect to the database using this admin_user userid, I am unable to expand any object node.
    I have played with different permissions, granting 'select any dictionary', 'select_catalog_role', 'select on dba_tables' but the user still can not view any objects via the appropriate node. eg. attempting to go to Other Users - username - Tables just shows nothing. (There are no filters).
    However the admin_user can run a SQL command to view the tables. eg. Select * from dba_tables, will list all tables for all users within the database. So they DO appear to have the appropriate access.
    So why can't they see the tables in the tables node?
    Is there some piece of configuration within SQL Developer itself that I have overlooked?
    Cheers

  • How to create an object within the same class???

    hi im just a newbie
    i v been always creating an object from the main class..
    but how to create an object inside the same class??
    i got main and students class
    the main got an array
    Students[] stu = new Students[]
    and i got
    stu[i] = new Students(id,name);
    i++;
    but i wanna do these things inside the Students class..
    i tried ..but i got errors.....
    how to do this
    .

    javaexpert, :)
    I really have no idea what you are trying to do since you say you've always been creating an object from the main class, yet you always want to create an object inside the same class.
    I'll assume that you have an object in the main class that you are trying to access from the Students class.
    If you are trying to access objects that are contained within the main class FROM the Students class, then know that there are two ways of doing so, one being static, and the other dynamic (look up definitions if unclear):
    1.) make the objects in the main class both static and public and access the the objects using a convention similiar to: Main.object; It's important to note that Main is the name of your main class, and object is a static object. There are better ways of doing this by using gettter/setter methods, but I'll omit that tutorial.
    2.) Create a new instance of the main class and access the objects using a similiar fashion: Main myInstance = new Main(); myInstance.myObject;
    You should really use getter and setter methods but I'll omit the code. In terms of which approach is better, step one is by far.
    I don't mean to be condecending, but you should really brush up on your programming skills before posting to this forum. This is a fundamenetal concept that you will encounter time and time again.

  • Assignment of Materials to Cost Object Nodes in Cost Object Hierarchy

    We have defined a Cost Object Hierarchy. In the Cost Object Hierarchy , there are multiple cost object nodes. These cost object node represents each Prodcution line.
    There is a requirement that any material can be produced in any production line.
    The issue I am facing is if I am assiging one material to one Production line, and again if I am trying to assign the same material to other production line, the system is not allowing me to assign it.
    How Can I resolve this issue.
    kindly help.
    regards

    Hi
    Ideally, each prod line should be represented by a Production Version in PP... You can assign a combination of Material + Prod Version to each Cost Obj Node... You cant assign just a Material No to more than 1 node
    The Prod Version Field might appear in Grey Mode.. But, it will allow you to select the Prod Version in that Field....
    You can also use BADI workorder_update to check while creating production order that the Prod Version being used in the Prod Order must be assigned to Cost Obj Node... Cost Obj Nodes are stored in the table CKPE

  • How to create a new object for a particular class?

    Hi,
      Can anybody please tell  the steps for creating a new object for a particular class.
    Thanks,
    Sreeja

    Declare the object as TYPE REF TO the class and use the CREATE OBJECT statement to create an object.
    DATA <obj_name> TYPE REF TO <class_name>.
    CREATE OBJECT <obj_name>.
    Please mark points if the solution was useful.

  • Garbage collection of objects created inside a method

    I have method and inside the method I create new Objects I mean I instantiate objects using new and call some methods on these objects.
    once the method execution is completed and control goes to caller of the method will all the object created inside the method will be garbage collected ?
    here with code
               public List<StgAuditGeneral> getAudits(
              List<StgAuditGeneral>  audits= new ArrayList<StgAuditGeneral>();
                  for(Map<String, String> result :results ){
                   audits.add(new MapToObject<StgAuditGeneral>() {
                        @Override
                        public StgAuditGeneral getObject() {
                                             StgAuditGeneral  stg= new StgAuditGeneral();
                             return stg;
                   }.getObject());
              }in the above method I cam creating tons of objects wil they be garbage collected immediatedly after jvm leaves the method ?

If and when they are actually collected is something we can't know or control, and generally don't care about. The only guarantee is that everything that can be collected will be collected before an OutOfMemoryError is thrown. So from our perspective, once it's eligible for collection, it is effectively collected.
    If you pass references to those objects to something else that holds onto them after the method ends, then they are still reachable, and not eligible for collection.
    However, you almost never need to even think about whether something is eligible for GC or not. It works pretty intuitively.

  • Can I create a Class object without the VM?

  • How to create an object of our own class by using Class.forName()??

    how to create an object of our own class by using Class.forName()??
    plzz anser my qustion soon..

    Class.forName does not create an object. It returns a reference to the Class object that describes the metadata for the class in question--what methods and fields it has, etc.
    To create an object--regardless of whether it's your class or some other class--you could call newInstance on the Class object returned from Class.forName, BUT only if that class has a no-arg constructor that you want to call.
    Class<MyClass> clazz = Class.forName("com.mycompany.MyClass");
    MyClass mine = clazz.newInstance();If you want to use a constructor that takes parameters, you'll have to use java.lang.reflect.Constructor.
    Google for java reflection tutorial for more details.
    BUT reflection is often abused, and often employe when not needed. Why is it that you think you need this?

  • Document(object, node-set)

    Using xsql 1.0.4.1, I'm having some trouble using the document(object, node-set) function defined in the XSLT 1.0 recommendation, sect 12.1:
    http://www.w3.org/TR/xslt#function-document
    I have a tag in my source xml document which contains a reference to another xml document. I want to construct an XPath expression for this other xml document. The path to the other xml document is specified relative to the source document.
    I'm doing something like this:
    Source Document:
    <blah>
    <some-tag redirect="answer.xml" />
    </blah>XSL:
    <xsl:template match="blah/some-tag">
    <xsl:variable name="redir" select="document(@redirect, / )" />
    <xsl:apply-templates select="$redir//somepath" />
    </xsl:template>
    ...However, Oracle XSLT always comes back with the following error:
    XSL-1013: Error in expression 'document(@redirect, / )'.I also get this error if I try
    document(@redirect, document(''))which is given as an example on pg 446 of Steve's book (but not what I want, since it resolves relative to the stylesheet).
    document(@redirect)works fine, but again is not what I want.
    Am I doing something wrong?
    Brian

    This is Oracle Bug# 1722555, hopefully which will be fixed in the 9.0.1.0.0 release. Currently the two-argument version of the document() function is not recognized properly.

  • Dynamically create a class based on database tables

    I am trying to build a database and tables on the fly, and save to the harddisk(done). Then I need to create a class using the info from the tables on the fly.
    For example,
    I built a database BANK, and a table Customer,
    Customer
    ID
    Phoneno
    Address
    Could I create a class named CUSTOMER (table name)
    dynamically, and have ID, PHONENO, ADDRESS,as the attributes of the class?
    Could anyone help or show the direction?
    Cheers.

    You could use a HashMap, and use the String keys "Customer", "ID", etc, and if you have primitive values like an int, you just wrap it inside Integer or any of the other wrapper classes, because HashMap only works with objects.
    Then you can use an ArrayList to hold all the records (one record is one HashMap as described above).

  • How to return Values from Oracle Object Type to Java Class Object

    PersonObjectType p = new PersonObjectType();
    p.load_object(4);
    There is a reocrd in the database with id = 4 and the function will execute successful. But if i try to use "p.getVorname()" i always get "NULL". Can someone tell me how to do that?
    Thanks a lot.
