Line Constructor

Hi
I have point geometries with id and i want to construct line geometry from this. If there are only two points for a line, i can pass start X, start Y, end X, end Y to sdo_ordinate_array.
But if i have intermediate vertices for a given id, how to do this as count of intermediate vertices is uncertain.
id x y
1 x1 y1
1 x2 y2
1 x3 y3
1 x4 y4
1 x5 y5
2 x1 y1
2 x2 y2
2 x3 y3
Thanks for your help..

Syed,
OK, here is an example that I hope reflects your situation.
Firstly, I will create a table called linepoints that I think contains data like yours:
create table linepoints as
SELECT case when trunc(level / 7) = 0 then 398639 else 2215595 end as feature_id,
       row_number() over (partition by 1 order by rownum) as point_id,
       sdo_geometry(2001,null,
                    sdo_point_type(round(dbms_random.value(1,10000),3),
                                   round(dbms_random.value(1,10000),3),
                                   NULL),NULL,NULL) as pointGeom
FROM dual
CONNECT BY LEVEL < 13;
-- Result
table LINEPOINTS created.This is what linepoints contains:
select * from linepoints;
-- Results

NotSerializable error while trying to write arraylist

I am getting a NotSerializable error while trying to write an arraylist to a file.
Here's the part of the code causing problem
File temp = fileOpenerAndSaver.getSelectedFile(); // fileOpenerAndSaver is a JFileChooser object which has been created and initialized and was already used to select a file with
currentWorkingFile = new File (temp.getAbsolutePath() + ".gd");      // currentWorking file is a file object
try
     ObjectOutput output = new ObjectOutputStream (new BufferedOutputStream(new FileOutputStream(currentWorkingFile)));
     output.writeObject(nodeList); // <-- This is the line causing problem (it is line 1475 on which exception is thrown)
     output.writeObject(edgeList);
     output.writeObject(nodesWithSelfLoop);
     output.writeObject(nextId);
     output.writeUTF(currentMessage);
     output.close();
catch (Exception e2)
     JOptionPane.showMessageDialog (graphDrawer, "Unknown error writing.", "Error", JOptionPane.ERROR_MESSAGE);
     e2.printStackTrace();
} As far as what nodeList is -- it's an arraylist of my own class Node which has been serialized and any object used inside the class has been serialized as well.
Here is the declaration of nodeList:
     private ArrayList <Node> nodeList; // ArrayList to hold a list all the nodesLet me show you whats inside the node class:
private class Node implements Serializable
     private static final long serialVersionUID = -4625153386839971250L;
     /* edgeForThisNodeList holds all the edges that are between this node and another node
      * nodesConnected holds all the nodes that are connected (adjacent) to this node
      * p holds the top left corner coordinate of this node. The centre. of this node is at (p.x + 5, p.y + 5)
      * hasSelfLoop holds whether this node has a self loop.
      * **NOTE**: ONLY ONE SELF LOOP IS ALLOWED FOR A NODE.
     ArrayList <Edge> edgeForThisNodeList = new ArrayList <Edge> ();
     ArrayList <Node> nodesConnected = new ArrayList <Node> ();
     Point p;
     boolean hasSelfLoop = false;
     int index = -1;
     BigInteger id;
                 ... some methods following this....
}Here is the edge class
private class Edge implements Serializable
     private static final long serialVersionUID = -72868914829743947L;
     Node p1, p2; // The two nodes
     Line2D line;
      * Constructor:
      * Assigns nodes provided as appropriate.
      * Also calls the addEdge method on each of the two nodes, and passes
      * "this" edge and the other node to the nodes, so that
      * this edge and the other node can be added to the
      * data of the node.
     public Edge (Node p1, Node p2)
          this.p1 = p1;
          this.p2 = p2;
          line = new Line2D.Float(p1.p.x+5,p1.p.y+5,p2.p.x+5,p2.p.y+5);
          p1.addEdge(this, p2, true);
          p2.addEdge(this, p1, false);
     }Here is the error I am getting:

     I inentionally did not write the whole error stack because it was way too long and I ran out of characters. But line 1475 is where I do the writeObject call. I also goet some weird not serialized exceptions before on some other classes that are not being written to the file or are not part of the object that I am writing. I serialized those classes and now it's this unknown object that's causing problems.
Edit: The problem may be due to the JFileChooser I am using to select the file as it is a non-serializable object. But I am not trying to write it to the file and in fact am just writing the arrayLists and BigInteger as objects to the file.

java.io.NotSerializableException: javax.swing.plaf.metal.MetalFileChooserUIThat's a Swing component and it is clearly related to the JFileChooser.
I also get some weird not serialized exceptions before on some other classes that are not being written to the file or are not part of the object that I am writing.That's a contradiction in terms. If you get NotSerialzableException it means the objects are being written. So they are reachable from the objects you're writing.
Edit: The problem may be due to the JFileChooser I am using to select the file as it is a non-serializable object.JFileChooser implements Serializable, but you're right, you shouldn't try to serialize it. But clearly this is the current problem. Somewhere you have a reference to it reachable via the object(s) you are serializing.
I suspect that Node and Edge inner classes and that you aren't aware that inner classes contain a hidden reference to their containing class. The solution for serializaition purposes is to make them static nested classes, or outer classes.

Creating class instances at different depths

I have a custom class called line that takes two sets of co
ordinates and draws a line between them.
The class uses _root.createEmptyMovieClip() to make a
container to draw in to but I need it to draw in to other movies on
the stage in a similar way to createEmptyMovieClip() eg
_root.childClip1.childClip2.line=new Line(x1,y1,x2,y2);
I have tried createEmptyMovieClip(),
this.createEmptyMovieClip(), _parent.createEmptyMovieClip() etc but
with no joy.
How can my Line constructor function get the path information
from the declaration or do I have to pass it as a parameter?

Whenever I design a class, that class always takes a
target:MovieClip parameter. then I create a container for the class
inside that target. This way, I can place my class objects inside
any clip I so desire at any level.

Hows should I do this?

Ok trying a bit of programming, first in ages...
Trying to make 2 classes, Player and GameTest. Ok, what i want to do is for a prompt to ask the user for firstname, secondname, nickname etc...you will see in the code.
This is player:
import java.io.* ;
class Player
    String line, firstName, secondName, nickName;
    int    age;
    char   sex;
    // constructor
    Player( String first, String last, String nick, int age, char sex )
       firstName = first ;
       secondName = last ;
       nickName = nick ;
    BufferedReader userIn =
        new BufferedReader(
        new InputStreamReader( System.in ) );
    System.out.println("Please enter your first name:" );
    firstName = userIn.readLine();
    System.out.println("Please enter your second name:" );
    secondName = userIn.readLine();
    System.out.println("Please enter your nickName:" );
    nickName = userIn.readLine();
    System.out.println("Please enter your age:" );
    line = userIn.readLine();
    age = Integer.parseInt( line );
    System.out.println("Are you male or female?:" );
    sex = userIn.readLine();
    //put in if m=male or f=female otherwise error
    void details()
          System.out.println( "Your details: " + firstName + secondName);//and all the rest....
}This is gameTest:
class GameTest
public static void main( String[] args )
    Player player1 = new Player(
        Andrew, Schofield, Sco, 22, M);
    System.out.println( "Your details: "
        + player1.details() );
}Now instead of me typing in my details into the code, i would like to be prompted on it, so do I need all the lines of code prompting in the player class, or the game test?
My overall idea is to have like a text based story game, you know with loads of decisions which effect the way the book turns out. I want those decisions to effect characteristics which the user enters at the start, so age will increase, nickname may change etc etc, all depending on decisions in the story. I may also need to add more than 1 player, so thats why i have the player class...
Could anyone modify my code so that it will do what I want, either that or give me some simple advice to follow, as I am kind of new to java.
Any help?
Sco

Ok I seem to be stuck now. have managed to creater a player object by having the details entered into the code. I dont know how to make it so that the user can input the details himself...well I kind of do. In one of the posts I showed above, I used the readline method, but I am not sure how to get thisinfo to go into the constructor in my test class. Sorry if this doesn't make sense... Here is what i have:
import java.io.*;
class Player
// instance variables
String firstName;   // First Name
String surName;     // Second name
String nickName;   // nick Name
int age;
String line;
// constructor
Player( String first, String sur, String nick, int age )
    firstName = first;
    surName   = sur;
    nickName = nick;
    this.age       = age;
BufferedReader userIn =
        new BufferedReader(
        new InputStreamReader( System.in ) );
// methods
String details()
    String result = "\nFirst Name: "+firstName+"\nSur Name: "+surName+"\nNickname: "+nickName;
    return result;
String names()
        System.out.println("Please enter your first name:" );
        firstName = userIn.readLine();
     System.out.println("Please enter your second name:" );
     surName = userIn.readLine();
     System.out.println("Please enter your nickName:" );
     nickName = userIn.readLine();
int age()
        System.out.println("Please enter your age:" );
        line = userIn.readLine();
     age = Integer.parseInt( line );
}Now I can make each of the attributes (ie the 3 names) into seperate methods if its going to be easier?
Now I want the info it stores to replace this line of code in PlayerTest.java
Player player = new Player( "Andy", "Schofield", "Sco", 22 ); That is what I am not too sure of. If you could help that would be great.
EDIT: Actually can i just replace "Andy" with firstName, "Sco" with nickName or will that not work? Also my age keeps on coming out as 0, do I need to do something there too?
Cheers
Andy

How can I resolve StackTrace data into a Method?

Howdy,
I am aware that using StackTraceElement will get me a method name, class name, and line number.
I'd like to resolve this information to a java.lang.reflect.Method, but when method names are overloaded there is no indicator (other than line number) which signature was called.
Has this problem been solved? Does someone have code to do this? Is there some key class or field somewhere that I have overlooked?
Thanks,
=Austin

The only way I currently know of to get caller info is to get a stack trace element from the current thread, or by creating a fake Throwable. It isn't really "caller info", though, just a bit of debug. It isn't really designed to be used by your application
Sadly, stack trace elements resolve file and line number info, but I'm not aware of a Method(file, line) constructor :( so I'm wondering if anyone has already done this work.There isn't one. This isn't really what stack traces were designed for, and the Java runtime doesn't really provide what you're after. I can't honestly think what use it would be, either

Print a line after each constructor

Would one of you java gods tell me how i can print a line after each constructor that tells me that the constructor has been constructed?

I do not know why you have declared the class as abstract. Abstract class must contain at least one abstract method.
In your code, there is no abstract method.
public Employee(String name, String address, String ssn,
            String id, double salary, double pay, String cvariable)
      name = EmpName;
      address = EmpAddress;
      ssn = EmpSsn;
      id = EmpEmployeeID;
      salary = EmpYearlySalary;
      pay = computePay;
      System.out.println("Constructor created");
     }The above code works only when you instantiate the object for the class. If it is abstract class, it will not work.
Abstract class cannot be instantiated.

Aerender error: "Unable to execute script at line 95. Window does not have a constructor"

A BG Renderer user is getting this error when running aerender version 10.5.1x2:
"Unable to execute script at line 95. Window does not have a constructor"
The render proceeds but the process never completes which is preventing the rest of the BG Renderer notifications from triggering. Any idea what this error means and how to fix it?
Thanks,
Lloyd

I guess we'll have to wait for Adobe to answer what could be causing the transmission to drop on Line 95. Todd's out of the office for a month or two, but maybe someone else can shed some light.

Constructors and command lines

I would like to know how you allow command line input for a constructor created object.
For example, my patient class has a constructor that will create a patient with 5 parameters id, name, age, etc.....
public Patient(int d, String n, int a, int s, int x) {
               id = d;
               age = a;
               tl = s;
               name = n;
               timearv = x;
In my Clinic class I would like to allow a user to be able to enter details on the command line to create a patient......DON'T KNOW HOW!!!
below is what i've come up with, but of course it doesnt work.....any help would be appreciated.....
Clinic c = new Clinic();
               System.out.println("Add patient details");
               Patient x = new Patient(id, name, age, tl,timearv);

Normally you present the user with a form consisting of fields the user fills in. When the user is finished and presses an OK button you read the filled-in fields and convert them to the internal types you expect/need. This information is then used to create objects.
You can read about this in the Swing tutorial.
A simpler way is to read from the standard input like this,
http://javaalmanac.com/egs/java.io/ReadFromStdIn.html
You can convert the read Strings to numbers like this,

Trying to use this() in a constructor, not the first line

I'm currently re-writing some old code of mine that was used to create a neural network. My main contructor, originally, was
public Network(int sizeLayer1, int sizeLayer2, int sizeLayer3) Now, however, I've decided that I want to make my network a little more general, and allow any number of layers. Therefore, my revised basic constructor is
public Network(int[] sizeLayers)which expects an array of ints corresponding to the size of each layer.
However, I've got some old programs that use the old contructor which I can't change (and anyway, it's good to have the option to be able to use both). I therefore want to create a constructor that has the same signature as the old one, but simply places the values in an array and passes the array to the new constructor.
public Network(int sizeLayer1, int sizeLayer2, int sizeLayer3) {
int[] sizeLayers = {sizeLayer1, sizeLayer2, sizeLayer3};
this(sizeLayers);
}obviously won't work, because 'this' must be the first line of the constructor. How can I put my values in an array and call the new constructor?
Thanks!

Silly me -- I had been trying to do
this({sizeLayer1, sizeLayer2, sizeLayer3});but of course that wouldn't work.
Thank you very much for that reply!
However, more generally, what if I wanted to do a few lines of processing on the variables passed, like adding them together before calling this()? Is there no way to do that? What's the purpose of requiring that this() be the first line in the constructor?
Thanks!

Value set in constructor is not getting saved in button Action method

Hi All,
I am not understanding why the value set ( On Condition )in constructor is not hold in the button actoin method.
Could any body explain me on that
for this I will try to explain with sample example
I have taken a button and add a integer property in session bean.
now if session bean's property is even then I am trying to set the button value to bidNow other wise Accept Invitation.
Till this opstion everything is OK
but once I click on Button,
Constructor is doing the right job only. But I do not understand why in button action I am getting the First Value only.
public Page1() {
        // <editor-fold defaultstate="collapsed" desc="Creator-managed Component Initialization">
        try {
            if (getSessionBean1().getIntValue()%2==0)
                button1.setValue("BidNow");
            else
                button1.setValue("Accept Invitation");
            getSessionBean1().setIntValue(getSessionBean1().getIntValue()+1);
            log("In Constructor Button Value : "+button1.getValue());
        } catch (Exception e) {
            log("Page1 Initialization Failure", e);
            throw e instanceof javax.faces.FacesException ? (FacesException) e: new FacesException(e);
        // </editor-fold>
        // Additional user provided initialization code
    public String button1_action() {
        // TODO Replace with your code
        log("In Action Button Value : "+button1.getValue());
        return null;
    }and here is the log

Can u explain the reason for this

Hi Sudhakar,
Please try the following and you will get an idea as to what is happening:
1. Drag and drop a button, 2 outputText components
2. Add a property to the session bean called intValue of type int. Customize it to set it's initial value to 0
3. Add the following lines of code to the constructor
outputText1.setValue("" + getSessionBean1().getIntValue());
getSessionBean1().setIntValue(getSessionBean1().getIntValue()+1);
4. Double click on the button component to go to the button action method.
5. Add the following line of code
outputText2.setValue("" + etSessionBean1().getIntValue());
6. Save and run the application
7. Watch the values of outputText1 and outputText2 with each click of the button
Also, try the application with the following code block in the button action method:
if(getSessionBean1().getIntValue()%2==0){
button1.setValue("Bid Now");
} else{
button1.setValue("Accept Invitation");
getSessionBean1().setIntValue(getSessionBean1().getIntValue()+1);
outputText1.setValue(button1.getValue());
outputText2.setValue("" + getSessionBean1().getIntValue());
When the above code block is in the button action method the values set to button are as expected.
Hope that helps
Cheers

Passing arraylist between constructors?

Hi guys,
I've pretty new to java, and I think i'm having a little trouble
understanding scope. The program I'm working on is building a jtree
from an xml file, to do this an arraylist (xmlText) is being built and
declared in the function Main. It's then called to an overloaded
constructor which processes the XML into a jtree:
public Editor( String title, ArrayList xmlText ) throws
ParserConfigurationException
Later, in the second constructor which builds my GUI, I try and call
the same arraylist so I can parse this XML into a set of combo boxes,
but get an error thrown up at me that i'm having a hard time solving- :
public Editor( String title ) throws ParserConfigurationException
// additional code
// Create a read-only combobox- where I get an error.
String [] items = (String []) xmlText.toArray (new String[
xmlText.size () ]);
JComboBox queryBox = new JComboBox(items);
JComboBox queryBox2 = new JComboBox(items);
JComboBox queryBox3 = new JComboBox(items);
JComboBox queryBox4 = new JComboBox(items);
JComboBox queryBox5 = new JComboBox(items);
This is the way I understand the Arraylist can be converted to a string
to use in the combo boxs. However I get an error thrown up at me here
at about line 206, which as far as I understand, is because when the
overloaded constructor calls the other constructor:
public Editor( String title ) throws ParserConfigurationException -
It does not pass in the variable xmlText.
I'm told that the compiler complains because xmlText is not defined
at that point:
- it is not a global variable or class member
- it has not been passed into the function
and
- it has not been declared inside the current function
Can anyone think of a solution to this problem? As I say a lot of this
stuff is still fairly beyond me, I understand the principles behind the
language and the problem, but the solution has been evading me so far.
If anyone could give me any help or a solution here I'd be very
grateful- I'm getting totally stressed over this.
The code I'm working on is below, I've highlighted where the error
crops up too- it's about line 200-206 area. Sorry for the length, I was
unsure as to how much of the code I should post.

Sorry if this post has been a bit lengthy, any help you guys could give

Hey. Couple pointers:
When posting, try to keep code inbetween code tags (button between spell check and quote original). It will pretty-print the code.
Posting code is good. Usually, though, you want to post theminimum amount of code which runs and shows your problem.
That way people don't have to wade through irrelevant stuff and
they have an easier time helping.
http://homepage1.nifty.com/algafield/sscce.html
As for your problem, this is a scope issue. You declare an
ArrayList xmlText in main(). That means that everywhere after
the declaration in main(), you can reference your xmlText.
So far so good. Then, inside main(), you call
Editor = new Editor( "Editor 1.0", xmlText );Now you've passed the xmlText variable to a new method,
Editor(String title, ArrayList xmlText) [which happens to be a
constructor, but that's not important]. When you do that, you
make the two variables title and xmlText available to the whole
Editor(String, ArrayList) method.
This is where you get messed up. You invoke another method
from inside Editor(String, ArrayList). When you call
this(title);you're invoking the method Editor(String title). You aren't passing
in your arraylist, though. You've got code in the Editor(String) method
which is trying to reference xmlText, but you'd need to pass in
your ArrayList in order to do so.
My suggestion would be to merge the two constructor methods into
one, Editor(String title, ArrayList xmlText).

Can you create a "constructor" for movie clips?

What I'm doing:
var this_array[counter] = new monster; //monster is a movie clip
init_monster(); //set's things like .name, .x, .y, etc.
What I want to do:
var this_array[counter] = new monster();
When I add a "monster" I then call a function to "initialize" all of it's stats.
Is there a way in the creation of the object, like with a constructor, where it automatilly does it on 1 line?
I'm teaching myself and am a little stuck on this part. If I have to create a "monster class" to do what I want just say so.
Any simple examples or links to simple examples would be great. Thanks in advance.

Ok so I've made a class Monster, and I have my movie object Red_Monster
How would I go about creating the variable so it knows it's both?
The only thing I can think of is linking them together as a .variable of the other.
Example:
var this_monster[x] = new Red_Monster();
this_monster[x].stats = new Monster();
It just seems a bit slopy, it would be nice to have this_monster know it's both. Is there a way to do that?
(added)
I've gotten Monster to extend MovieClip, and this is working to use it as a movieclip.
Currently trying to change the image of the movie clip in code to Red_Monster. Is there a way to do that?
(added)
Found how to do it, sort of. Change the class linkage name to Monster instead of Red_Monster. I just have to make classes for each movie clip.
(last add, answer for anyone else)
Ok the answer is to create a Monster class that extends MovieClip. Then for each color_Monster they all extend Monster, no other code needed inside each class other then the constructor.

How can i copy line with text and image to ms word

When I insert an image in textflow using InlineGraphicElement it works, but when I copy the line with the image to MS Word it copies only the text (not the image).
How can i copy the image to MS Word?

If you want copy formatted text and image to MS Word, you need to give MS Word rtf markup, because Word can recognize rtf markup but not TLF markup.
So you need to create a custom clipboard to paste a rtf markup. It's a large feature for you, because you need a tlf-rtf converter in your custom clipboard.
TLF Custom Clipboard Example:
package
    import flash.display.Sprite;
    import flash.desktop.ClipboardFormats;

    import flashx.textLayout.elements.*;
    import flashx.undo.UndoManager;

    // and adds a handler for plain text that strips out all consonants (everything except aeiou).
