How can I pass an object to a function by value?

Hi
I have a function with an argument. this argument is an object. I don't want to alter this object. But java passes this object by reference and some fields in this object are altered after function return.
How can I pass this object by value and keep my original data unbroken?
thanks for any help

How can I pass this object by value and keep my original data unbroken?How you approach it is likely to depend on how much control you have over the code in question. If it's legacy code and has been badly designed, there's probably very little you can do to protect existing code short of a complete refactoring.
What you could do as an interim measure is:
1. Create an immutable wrapper to your existing mutable class.
2. Create new methods that replicate the existing ones, but take the immutable class instead.
3. Deprecate the old methods.
This won't break client code, but they will now get warnings when they compile and you can add documentation to point them to the new class/methods.
If you are in control of the code (especially if you're still in the design stages), you've got several options:
1. As Dr.Clap says, make your class immutable (probably best).
2. If this isn't possible, create mutable and immutable variants of your class. This is often best achieved by hanging them both from an interface.

How can i pass the PROPERTY_FALSE as string

Hi,
How can i pass the PROPERTY_FALSE & PROPERTY_TRUE as string to
     Set_Item_Property('MY_BLOCK.MY_ITEM',ENABLED,PROPERTY_FALSE);
my requirement is to write a procedure like enable_fields(P_PROERTY_VALUE ..) that enable or disable many items based on the value that i pass.
Set_Item_Property('MY_BLOCK.MY_ITEM',ENABLED,P_PROERTY_VALUE );
Thanks in advance.

Infact , property_false and property_true are not strings, They are constants with values 5 and 4 respectively.
So where ever you want to have property_false, pass 5
and property_true , pass 4
But usually we dont follow this method , as the value of the constants may vary from version to version.
So in your procedure say, pass 1 for enable and 2 for disable
procedure (................, p_property number) is
m_set_enable number ;
Begin
If p_property = 1 then
   m_Set_enable := property_true;
else
   m_Set_enable := property_false;
end if;
set_item_property('item1',enabled,m_set_enable);

How can I pass an empty array to a parameter of type PLSQLAssociativeArray

How can I pass an empty array to a parameter of type PLSQLAssociativeArray in VB? I defined the parameter like this
Dim myArray() as String = new String() {}
Dim myPara as new Oracle.DataAccess.Client.OracleCollectionType.PLSQLAssociativeArray
myPara = 0
myPara.Value = myArray
When I execute my stored procedure giving the above parameter, I got error saying OracleParameter.Value is invalid.
I have tried to give it the DBNull.Value, but it doesn't work either.
Note: everything works fine as long as myArray has some item in there. I just wonder how I can make it works in case I have nothing.
Thank you,

How can i pass the Input value to the sql file in the korn shell ??

Hi,
How can i pass the Input value to the sql file in the korn shell ??
I have to pass the 4 different values to the sql file and each time i pass the value it has to generate the txt file for that value like wise it has to generate the 4 files at each run.
can any one help me out.
Raja

Can you please more elaberate., perhaps you should more elaberate.
sqlplus is a program. you start it from the korn shell. when it's finished, processing control returns to the korn shell. the korn shell and sqlplus do not communicate back and forth.
so "spool the output from .sql file to some txt file from k shell, while passing the input parameters to the sql file from korn shell" makes no sense.

How can i pass more than 1 param to servlet to show blob image

Hi
my servlet expects 2 param to SELECt an image from a blob column
public class ImageBlobServlet extends HttpServlet {
private static final String CONTENT_TYPE = "text/html; charset=windows-1252";
public void init(ServletConfig config) throws ServletException {
super.init(config);
public void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException,
IOException {
response.setContentType(CONTENT_TYPE);
String ImageId = request.getParameter("id");
String TipImg = request.getParameter("tip");
OutputStream os = response.getOutputStream();
Connection conn = null;
try {
Context ctx;
ctx = new InitialContext();
DataSource ds = (DataSource)ctx.lookup("java:/comp/env/jdbc/rhDS");
conn = ds.getConnection();
PreparedStatement statement = conn.prepareStatement("select FIT from " +
"RHH_FOTOS IMG " +
"where IMG.IDASSO = ? and IMG.TIM_COA = ?");
statement.setInt(1, new Integer(ImageId));
statement.setString(2, TipImg);
To display the image i tried to use:
<af:image id="ot1"
*source="/imageblobservlet?id=#{bindings.Con.inputValue}?tip=#{"EMP"}"*
shortDesc="Foto"/>
but i receive all content in the get of first param.
String ImageId = request.getParameter("id");
How can i pass one more then 1 param in EL.
Thanks in advance

Hello,
seems to me you're using wrong separator for the second param into your URL:
<af:image id="ot1" source="/imageblobservlet?id=#{bindings.Con.inputValue}
tip=#{"EMP"}" shortDesc="Foto"/>
I think it should be:
<af:image id="ot1" source="/imageblobservlet?id=#{bindings.Con.inputValue}
tip=#{"EMP"}" shortDesc="Foto"/>

How can I pass arguments from one MIDlet to another MIDlet

Hi everybody !
Can anybody help me in knowing that how can I pass the parameters from one
MIDlets to another one in same application.
I am devloping a application in which I am using more than two MIDlet and I
want to transfer Parameter from one MIDlet to another one.
I just explain what I have done....
I made a MIDlet "A" and "B" in the same project using NetBeans IDE.
In MIDlet "A" I create the Object of MIDlet "B" so that the constructor of
MIDlet "B" is called and parameter can be transferred.
But when I run the program it shows me two MIDlet on the screen, that I
doesn't need.
Suggestion are most welcome....
Thanks in advance
Regards
Bhagwat

If you create two MIDlet in a midlet suite, it will display as you mentioned means you can't change the display style.

How can I pass data generated in a SubVI inside a Case Structure out of the Case Structure?

Hello,
I am using a USB 2701 to control a heater. I have three SubVIs that are all working properly on their own. I'd like to use an Enum to select which of the SubVIs is running at a given time. The problem is that no data is passing out of the case structure. How can I pass the temperatures and heater outputs acquired by the SubVIs to the main VI? I've attached my some of my code below. I can't attach more than 3 files, but you can see how the main VI is configured. Like I said, the SubVIs are working individually, so you shouldn't really need to look at them.
Thank you,

CJones,
You might check a couple of things.
Your HeaterTCD... VI has a While loop with a stop button condition. HeaterTCD pass out values only when it finishes running. If it doesn't pop open the front panel (which usually doesn't happen when running a SubVI) you could run into a stuck loop because you don't have access to the Stop button. This could appear in the form of no data being passed out (because the SubVI never stops running). The primary VI opens the HeaterTCD VI, starts it, and waits for the VI to finish and pass final values .
Secondary note: Unless you want your SubVI panel (which probably isn't open when running the main VI) to update continuously, consider moving your Temperature Graph and Temperature oC indicators outside the while loop. Pass final values to them via a tunnel, since the main VI will only read their values after the loop finishes running, anyway.
It might help to add error management to HeaterTCD like you have for RampHeater. If you connect error lines with Error Outs to your main VI, that will help tell if there is an error somewhere that is preventing info output.
RampHeater SubVI has the same issue with the stop button. It is also probably getting stuck in the While loop waiting for a manual push of that SubVI's Stop button.
An easy way to test this would be to set up a logic circuit so that when the While loop iteration counter reaches a certain number, it registers True and sends it to the conditional. I know this isn't what you want to do long-term, but if that lets your SubVI return outputs it means that the SubVI was just never stopping.
Hope that helps.

How can I pass multiple condition in where clause with the join table?

Hi:
I need to collect several inputs at run time, and query the record according to the input.
How can I pass multiple conditions in where clause with the join table?
Thanks in advance for any help.
Regards,
TD

If you are using SQL-Plus or Reports you can use lexical parameters like:
SELECT * FROM emp &condition;
When you run the query it will ask for value of condition and you can enter what every you want. Here is a really fun query:
SELECT &columns FROM &tables &condition;
But if you are using Forms. Then you have to change the condition by SET_BLOCK_PROPERTY.
Best of luck!
