MultiDimensional Array or what????

Hi Guys
I have created an xml document that has this structure for
each child:
<work>
<client>Telstar Records</client>
<titled>Stargate Music.co.uk</titled>
<thumb>images/thumbs/stargate_sm.jpg</thumb>
<description>They were an up and coming band, i was a
designer with a passion for 3d, they met fell in love and a new
site was born. All it took was four press shots, one promo and a
lot of imagination</description>

I have succesfully created buttons and used an associative
array to compile the info for each button, woooooo aren't i
clever!!!! I have set up a path to the <images> node, but I
am stumped as to how i can pull the information from the
'workImages' variable in my getworkData() function below .
I need your help, as i would like to create buttons of the
childnodes named <image> in the xml, above you can see that
if i was successful i would have three buttons. My problem is
relating the information to the buttons and making the buttons
appear. I am not using a for loop as i would like to animate each
button using a scripted tween. as in the makeButtons() function.
Do I need to create a multidimensional array? I have included
my code below, please don't get too lost in it, i hope someone can
fathom it for me and give me an answer. My associative array is in
the function getworkData(); My function to create the 'image'
buttons is called portfolioImageCreator();
Many thanks
Jim

You could use a table of records or a record group. They both achieve similar results but with very different syntax. I am not sure if there is any difference in performance.
Record groups are good for certain things like lists populated from the database because built-ins are provided for manipulating them. If you are going to do the manipulation programatically, I personally find the syntax for tables of records less cumbersome than record groups. Learning the syntax for tables of records is also likely to be more universally useful to you as they have various uses such as passing data between procedures.
In your situation the table of records needs to exist throughout the forms session rather than just during the execution of a single pl/sql block. The way to do that is create a program unit which is a package header without a body. Declare the table in there and it can be used throughout the form.
However, if you only ever want to keep 5 records, it would probably be easier just to have 5 ordinary items in a control block on the null canvas (or global variables). When you want to record your new action just do:
:item5 := :item4;
:item4 := :item3;
:item3 := :item2;
:item2 := :item1;
:item1 := :new_stuff;
You could even construct the above in a loop using
copy(name_in('item'||i),'item'i+i)
but with only 5 items to manipulate, is it worth the bother ?
Whatever method you decide to use, you are not going to get anything simpler than 5 little assignment statements.

  • Bindind data to multidimensional Array

    I have a multidimensional Array (3D). I have some fields which I want to bind to some TextInputs:
    model.creditosConsumoModel.literaturaCredito[i][j][k]
    And here's a example of the data binding:
    text="{(model.creditosConsumoModel.literaturaCredito[4][12][0] as Apartado).texto}"
    The problem is: When I do a: model.creditosConsumoModel.literaturaCredito = new Array and I define the Array again with new data everything gets blank (all the text Inputs) and I loss the information.
    Resume: It only works the first time, but not the rest of the times.
    Thanks and regards!!!

    @Pauland
    That's what I was thinking as it was an array of arrays.
    @quebequiano
    Generally, for something like this, I make a wrapper object and set the values on that so I don't have to deal with issues like this.  I'm not sure how architecturally sound it is, but it sounds like you are trying to take small pieces of data and prepare them for your view, in which case a wrapper/adapter would provide you with the benefits of databinding.
    P.S Does your name mean "Quebecian" in spanish ?

  • Problems making windchill chart using multidimensional arrays

    Alright i am doing a program for my java class. The book doesnt tell me much and the teacher didnt either cause we had a midterm to take. Alright in this program i have to write a java program that produces a wind chill chart with temperatures from 50 to -50 degrees f in steps of 10 degrees, with wind speeds from 5 to 50mph, in steps of 5mph. The following formula may be useful.
    windchill= ((10.45+6.686112 * sqrt(windspeed)- .447041 * windspeed)/22.034)*(temperature- 91.4) + 91.4
    use for statements in your program and a function to calculate the wind chill factor at a given temperature and wind speed.
    I know im gonna have to use multidimensional arrays to do this problem, unless someone has an easier way to do it. I am really stuck. I have this so far.
    import javax.swing.*;
    public class lab7
    public static void main( String args[] )
    int a[][] = {{5,10,15,20,25,30,35,40,45,50},
    {-50,-40,-30,-20,-10,0,10,20,30,40,50}};
    System.exit(0);
    I am not even sure if that is correct but the major problem is how can i get the program to show a table with the temperature on the x coordinate at the top the wind speed on the y axis and then having the program use those arrays to calculate the windchill and put that in the table. I am really stuck and i was wondering if u guys could give me a little push in the right direction. The book doesnt say much so thats why im asking.
    Thank you everyone.

    I have no clue what i am doing right now. I am so confused it isnt even funny. I am trying something new to see what happens. The decimalformat didnt do anything for me. I have the numbers i just want to be able to put them into a chart. I wish my teacher would actually teach, and the book actually say how to do stuff.
    This is my program:
    import java.text.DecimalFormat;
    public class lab7
    DecimalFormat twoDigits = new DecimalFormat ("0.00");
    static private double windchill(double s, double t) { 
    return (((10.45 + 6.686112 * Math.sqrt(s) - .447041 * s)/(22.034))*(t-91.4) + 91.4);};
    static void print(double s, double t)
    {   System.out.print(" "+windchill(s, t));};
    static private void printRow(double s)
    { // the speed is assumed constant  
    for (double t= -50; t <= 50; t+= 10) // loop over the temperature values
    print(s, t); // print a row value
    System.out.println();};
    static private void printChart()
    {   for (double s= 5; s <= 50; s+= 5)      
    printRow(s);};
    public static void main(String args[])
    for (double t= -50; t <= 50; t+= 10) // loop over the temperature values
    {System.out.print( "   " + t);};
    System.out.println();
    System.out.println();
    for (double s= 5; s<=50; s+= 5)
    {System.out.println(s);};
    printChart();
    I am probably way off and this program is due tomorrow and i am going nuts. I tried to do it during the week and it didnt work out to well.

  • Multidimensional array and chars

    Hi again,
    My apologies in advance if i can't word my question that well, i will try and be as clear and succinct as possible and hopefully for this newbie you can apprehend what i'm trying to figure out if i come up short.
    I'm trying to write a rather large control statement with a while loop and several nested ifs inside it that ultimately returns a single character after all is said and done, and then continually concatenates that character to a string which will eventually be output to a file. The part i'm stuck at is after i've changed the two letter characters into their ASCII values. I need to make the program take those two ASCII values and use them as a reference to a character in a multidimensional array of alphabetic characters, and then that character will be what is returned at the end.
    Here's the method, thanks in advance for your time.
    public String encode( String cipherKey )
            String textToEncode = input.next();
            String encodedText = " ";
            cipherKey = cipherKey.toUpperCase();
            textToEncode = textToEncode.toUpperCase();
            openFiles();
            int numberOfChars = textToEncode.length();
            int cipherPos = 0;
            int cipherLength = cipherKey.length();
            while (input.hasNext())
                for ( int count = 0; count < numberOfChars; count++ )
                    if (Character.isLetter(textToEncode.charAt(count)))
                        cipherPos %= cipherLength;
                        int xChar = (int) textToEncode.charAt(cipherPos);
                        int yChar = (int) textToEncode.charAt(count);
                        xChar -= 65;
                        yChar -= 65;
                        if ((xChar >= 0) && (xChar <= 25))
                            if ((yChar >= 0) && (yChar <= 25))
                        return ' ';
                     encodedText = encodedText +
        return encodedText; 
        }As you can see towards the end there are some incomplete statements where i became lost.

    its there, i couldnt c&p the whole program because it went over my character limit. Yeah it did compile but couldn't invoke my encode method without a NullPointerException.
    Here are the other methods in the class....

  • Multidimensional array in jquery class/object

    I'm trying to get into javascript and jquery for a hobby project of mine. Now I've used the last 4 hours trying to find a guide on how to create class objects that can contain the following information
    Identification : id
    Group : group
    Persons : array(firstname : name, lastname : name)
    Anyone know of a tutorial that can show me how to do this?
    I found this page where I can see that an object can contain an array, but it doesn't state whether it is possible to use a multidimensional array.
    And this page just describes the object with normal values.
    Any pointers in the right direction are appreciated.

    There are no classes in JavaScript. It uses a different style of objects and what you found is indeed what you need.
    Well, it might help to think about it as a dynamic, runtime-modifiable object system. An Object is not described by class, but by instructions for its creation.
    Here you have your object. Note that you can use variables everywhere.
    var id = 123;
    var test = {"Identification": id,
    "Group": "users",
    "Persons": [{"firstname":"john", "lastname":"doe"},{"firstname":"jane","lastname":"doe"}]
    This is identical to the following code. (The first one is a lot nicer, though.)
    var id = 123;
    var test = new Object();
    test.Identification = id;
    test["Group"] = "users;
    test.Persons = new Array();
    test.Persons.push({"lastname":"doe","lastname":"john"});
    test.Persons.push({"lastname":"doe","lastname":"jane"});
    As you can see, you can dynamically add new properties to an object. You can use both the dot-syntax (object.property) and the hash syntax (object["property"]) in JavaScript.

  • JNI multidimensional Array and OpenCV

    Hello everybody,
    my first post, so lets go..
    At the moment I am writing my thesis in the filed of automatic image classification. The project is written in Java, but I wanna use the OpenCV library from Intel (http://sourceforge.net/projects/opencvlibrary/) for facedetection.
    So far I managed to call the native method from Java. What I do I parse the path of the image to be analyzed as a string to my C++ programm. The faces are being detected and written into a so called CvSeq (http://www.comp.leeds.ac.uk/vision/opencv/opencvref_cxcore.htm#cxcore_ds_sequences) which holds the coordinates of the rectangles surrounding the found faces. Until now I can only call cvSeq->total which gives me the total number of faces as ints. That integer I return to my java api.
    What I don't know is, how to return a multidimensional array (2 dimensions) where the first dim contains the path as a string to the file and the second dimension 3 integers for x,y coordinates and the lenght of each rectangle.
    Or better, I might know how to return that Array, but not how to create it.
    I know this is somewht OpenCV specific, but maybe someone knows anything. Any little help would be greatly appreciated. Thanks a lot!!!!

    Any Java array you can consider like one-dimensional array of arrays n-1 dimension. For example, you have a 3 dim. array of objects:
    Object[][][] arr = new Object[1][2][6]; It can be considered as a set of one-dimensional arrays:
    ==========================================
    |  dim   |           Type
    ==========================================
      0          1 element, an array of type �[[Ljava/lang/Object;�
      1          1 x 2 elements , an arrays of type �[Ljava/lang/Object;�
    So you can convert three-dimensional array to one-dimensional array like in C++:
    |�[Ljava/lang/Object;� | �[Ljava/lang/Object;� | �[Ljava/lang/Object;�
         6 objects                 6 objects                 6 objects

  • Question on System.arraycopy method and multidimensional array

    I'm trying to copy from single dimensional to multidimensional array using System.arraycopy method. The following is my problem.
    1) I need to specify the index of the multidimensional array while copying. Can I do that ? If yes , how???
    eg ; int a[] = new int[3];
    int b[] = new int[3][2]; I need to copy from a to b
    I tired the following and I'm getting an error.
    System.arraycopy(a,0,b[][1],0,3);
    How Can I achieve the above?? PLease Help --------------

    Java doesn't have multidimensional arrays. When you see an int[][] it's an array of arrays of ints. The arrays of ints might have different lengths like this one:int[][] arr =
    {{1,2,3,4},
    {1,2,3},
    {1,2},
    {1}
    };Do I need to say that arraycopy as you see it would fail in this case?
    If you know what kind of arrays you'll have you can simply implement your own arraycopy method (but it will not be as effecient as System.arraycopy) with a simple for-loop.

  • Synthesis bug with SV packed multidimensional array slices

    I've been using SV packed multidimensional arrays to do things like representing a bus which is many bytes wide, e.g. a 128-bit bus can be declared like this:
    logic [15:0] [7:0] myBus;
    You should be able to write "myBus[15:8]" to get the upper 64 bits (8 bytes) of this 128-bit wide packed value. However, I've found that in some expressions this produces some very buggy behavior. I've reduced it to a simplified example, with comments to show what works and what doesn't.
    `timescale 1ns / 1ps
    module sv_array_select (
    input logic sel,
    input logic [3:0] [1:0] i,
    output logic [3:0] outA,
    output logic [3:0] outB,
    output logic [3:0] outC
    // Works; equivalent to assign outA = {i[1], i[0]};
    assign outA = i[1:0];
    // Works; equivalent to assign outB = {i[3], i[2]};
    assign outB = i[3:2];
    // FAILURE
    // Synthesizes to equivalent of:
    // assign outC[2:1] = sel ? i[2] : i[0];
    // assign outC[3] = 1'bZ;
    // assign outC[0] = 1'bZ;
    assign outC = sel ? i[3:2] : i[1:0];
    endmodule
     I get this result in Vivado 2015.2 and 2013.2, haven't tried other tool versions.

    ,
    Yes, I can see that incorrect logic is getting generated by the tool.
    I will file a CR on this issue and will let you know the CR number.

  • How to save joint's coordinates into multidimensional array

    Hello everyone, 
    i have a question that's seems silly but i'm stuck in it since yesterday !
    i'm developping a small application with ms kinect sdk 1.7 and when detecting skeleton and all joints are tracked i want to save it into multidimensional array of (20,3) which are respectively the number of joints in human body and the coordinates along
    the 3 axes. 
    my goal is to calculate after that the max and the min values throught the 3 axes.. so i began with this piece of code.
    private static double[][] JointTab = new double [20][3];
    double save_joints(Skeleton first)
    foreach (Joint j in first.Joints)
    for (int li = 0; li < 20; li++)
    JointTab[li][0] = j.Position.X;
    JointTab[li][1] = j.Position.Y;
    JointTab[li][2] = j.Position.Z;
    return JointTab;
    it indicates that the method does not return a value necessary ? how could i fix this error ? 
    i will need to call the JointTab after that how can i sort each colomn with Array.Sort() method  ?
    thanks for any help ! 
    DKF

    The issue you are having is not specific to the Kinect SDK. You will need to look into your managed code construction of the array since that is not valid. There are ways to create a single array of a structure which you can then provide your own enumeration.
    You may want to look at the generic collections of .Net to see what would be best since you will way to provide some logic to the sort since the points in space will need to calculate a length.

  • Drawing multidimensional array values

    Hi all,
    Need a bit of advice about turning a multidimensional 64x64 array (consisting of doubles) into a picture(!). The array contains a large number of 0.0 values (also known as a sparse matrix). For each value in the array i want to plot a little Rectangle whose colour varies as a function of its value (the values in the array are normalised and range between 0.0 and +1.0). The location of each rectangle on the screen (or Frame/ Panel or whatever) should reflect the position of the value in the array i.e. a value at index myArray[0, 0] should appear in the top left hand corner of the screen (or whatever).
    I am not sure which way is the best to achieve this and am eager to hear some suggestions.
    Thx in advance

    I started going mental last time I thought about picturing multdimensional arrays. I got thinking along the lines that a 2D array looks like a grid, a 3D would look kinda like a cube... but then you hit 4D, and so on, and .... well, my mind just doesn't look like that.
    I think maybe the best way to visualize a massive multidimensional array would be almost like a directory structure. ie. One item can expand to have a bunch more items, which would in turn have more items. This is basically what a MD array is. And if you're talking about having to display the data, this might not be a bad arrangement, since you could actually expand/collapse single elements of the array, like a directory tree, and thus have less data cluttering your screen at one time.

  • Multidimensional arrays

    I need help in creating a program that assigns a rock star name when they enter their own name. It must assign the same name to the same user's name, but different last names when that changes.

    I have known Java since Nov 2006, but I have always dodge some of this difficult stuff. I am totally self taught and I have been learning through the Internet and a very old Java 2 book. So please speak "dumb" to me.

    Oh, grow up. If you get insulted this easily, you'll be inconsolable when you have to get a real job. I'm so sick of these children who want help but also want their genius to remain unquestioned.
    Anyway my point wasn't that you altered the image, but rather that you were careless in what you presented as data. Some of the stuff on that image couldn't possibly have worked with the code you posted. (In particular "java node" would not have even run. It wouldn't produce any output at all other than an error message.)
    Part of debugging is gathering real, useful, accurate information. And if you want help debugging you have to share real, useful, and accurate information. If you gather output and then change your code, you should at the very least make this clear.

  • Problems manipulating multidimensional arrays

    hello, I am new to java programming. I would like to know some techniques in which i can change the data within multidimensional arrays. For example, with a 2d array, (int [row][column] a), the index of the rows are the columns, and each column contains an element. I would like to know how to, for example, switch the order of the indexes of the rows and columns. So for row 1, the columns (the indexes) are 0,1,2,3. after switching the order, it would be 3,2,1,0. Is there any possible way to do this? a reply would be appreciated. Thank you.

    Carefully read the following: given a two dimensional array, we can
    define a simple wrapper:public interface ArrayWrapper {
       public int rowDim();
       public int colDim();
       public int get(int row, int col);
       public void set(int row, int col, int value);
    }... here's a very simply 'real' ArrayWrapper:public class RealArrayWrapper implements ArrayWrapper {
       private int[][] array; // what it's all about
       public RealArrayWrapper(int[][] array) { this.array= array; }
       public int rowDim() { return array.length; }
       public int colDim() { return array[0].length; } // assume a non-ragged array
       public int get(int row, int col) { return array[row][col]; }
       public void set(int row, int col, int value) { array[row][col]= value; }
    }... here's a wrapper that does nothing, given another wrapper:public class NilWrapper implements ArrayWrapper {
       private ArrayWrapper wrap;
       public NilWrapper(ArrayWrapper wrap) { this.wrap= wrap; }
       public int rowDim() { return wrap.rowDim(); }
       public int colDim() { return wrap.colDim(); }
       public int get(int row, int col) { return wrap.get(row, col); }
       public void set(int row, int col, int value) { wrap.set(row, col, value); }
    } ... and here's one that reverses all rows:public class RevRowWrapper extends NilWrapper implements ArrayWrapper {
       public RevRowWrapper(ArrayWrapper wrap) { super(wrap); }
       public int get(int row, int col) { return super.get(rowDim()-row-1, col); }
       public int set(int row, int col, int value) { super(rowDim()-row-1, col, value; }
    }... do you get the picture?

    Look in to passing user defined type back and forth to Oracle. Any type that oracle supports, you can constract on the java side and send it across. Look into the SQLData class.

  • Multidimensional Array in Indesign?

    Hey guys,
    normally in javascript I can just create a multidimensional array like so:
    myArray = [ [] ];
    and then assign values like this:
    myArray[0][0] = 'item1';
    In extendscript I get the error "undefined is not an object". Is there something I forgot about, or is this just not possible in Indesign?

    I found out it was another problem. The code works like this, but you need to define in the beginning how many arrays are in the array. Otherwise it will throw the "undefined" error.
    points = new Array(object.paths.length);
    for(i = 0 ; i<object.paths.length; i++){
        points[i] = new Array();
    This code works now, as the length of the array is exactly the length you need. And for every key you add another array, to create your two dimensional array on every key.
