How can a function return a constant reference to an object

how can a function return a constant reference to an object so that the calling party dont have rights to change it.
like this example
class obj = somefunc();
obj.changeit(); // this line lust give error saying that its read only..
somefunc()
return criticalobj;
in c++ we can achieve this by using the const pointer to the object.. how can we do this in java???

If you can read this, you're too close!

  • How can I Create return order with reference to an ARCHIVED invoice

    The standard "Reference" process does not work when the invoice has been archived. Has anyone solved this problem?

    This is because the archived document is not available in the database and the archived document can be used only for viewing the data. Normally only very old documents (like more than 7-10 years old) are archived, so I am just surprised, why a return order is created for a very old document (sales process)?

  • How can a function returning character length greater than 4000 be selected in SQL

    Hi,
    I want to know if there is a way to write a select query on a function call which returns a varchar of more than 4000 characters.
    CREATE OR REPLACE FUNCTION FUNC1
    RETURN VARCHAR2
    IS
    str VARCHAR2(32767);
    BEGIN
         str := <some string greater than 4000 char>;
          RETURN str;
    END;
    SELECT FUNC1 from dual; ---- This gives an PL/SQL numeric or value error. Character string buffer too small.
    Is there any way to resolve this?
    Thanks

    32767 is not default. The default is still 4000 for VARCHAR2. You need to set the initialization parameter MAX_STRING_SIZE= EXTENDED for 32767.
    Text from Oracle documentation
    Extended Data Types
    Beginning with Oracle Database 12c, you can specify a maximum size of 32767 bytes for the VARCHAR2, NVARCHAR2, and RAW data types. You can control whether your database supports this new maximum size by setting the initialization parameter MAX_STRING_SIZE as follows:
    If MAX_STRING_SIZE = STANDARD, then the size limits for releases prior to Oracle Database 12c apply: 4000 bytes for the VARCHAR2 and NVARCHAR2 data types, and 2000 bytes for the RAW data type. This is the default.
    If MAX_STRING_SIZE = EXTENDED, then the size limit is 32767 bytes for the VARCHAR2, NVARCHAR2, and RAW data types.

  • Can a function return more than one item or object?

    Hi I am trying to move text movies and textfields around a stage. This is a learning curve for me. I am confused by an example I have found on the internet.

    What type of object is
    var letter:Object = getLetterObject(_text.charAt(i));  // in the draw function
    as it has properties
    letter.stepDegrees = _totalAngle / numOfLetters;
    getLetterObject()
    seems to return lotts of stuff which would not be done in other languages like C
    return
    movie:movie,
    field:field,
    widthInDegrees:0,

    Hi
    I still think I need an Object parent child linkage diagram on this to get my head around it.
    It seems that things are reversed so that it is Object:value. Kind of confusing to see movie:movie.
    var letter:Object = getLetterObject(_text.charAt(i));
    letter holds the following objects
    MovieClip:Movie
    TextField:field
    widthInDegrees:0  // What is this. What type is a  widthInDegrees
    fieldWidth:field.width // Same as above
    fieldHeight:field.height  // Same as above
    And to cap it all, back in the calling function draw()
    letter.stepDegrees = _totalAngle / numOfLetters;  //  What is stepDegrees a property of? MovieClip,TextField,widthInDegrees,fieldWidth or fieldHeight
    I can understand the first two but not the last three
    For example widthInDegrees is not mentioned anywhere in the code. and
    letter.stepDegrees // implies that stepDegrees is a property of Object:letter.
    Do you throw a property and value blindly at the letter object and let flash work out which object it is a property of?
    MovieClip & TextField do not have this property. Searched the web for this information. We need an equivelent of MSDN.

  • Can oracle  function return more than one value

    Hi All
    please answer can oracle function return more than one value
    need one schenario
    regards

    Can any function, irrespective of the language, return multiple values?
    OF COURSE NOT!!
    So why do you think Oracle will now suddenly do it differently than all other languages? Never mind that it is impossible for a function (a unit/module of code) returning a memory address, to return multiple memory addresses. The machine code that does that, has not been yet been designed/implemented.
    I am continually amazed that this question is asked. It is about something so fundamental in almost every single 3rd and 4th generation language... something that is taught right at the start... the definition of what a procedure and what a function is.
    Sorry, but I simply cannot pull punches on this subject and smooth it over. There is something fundamentally wrong with your training as a programmer if you have to ask such a question about a function.
    And whatever programming skills you build on such a foundation, will be seriously lacking.
    I kindly suggest that you get back to the very basics of programming - and review and revisit until you fully understand it. There are no shortcuts in becomming a good programmer.

  • Can a function return two values???

    Hi guys can a function return more than values?

    Or even better return an Object.
    ie

  • How can I make a button that on press the object appears and on second press the object to disappear

    Hello,
    I'm quite new to flash programing, and I don't know how can I make a button that will make the object appear and disappear.Till now I have this code for the appear:
    on (press)
        _root.top1.gotoAndStop(2);
        _root.topp.gotoAndStop(2);
        _root.mm1.gotoAndStop(2);
              _root.m1.gotoAndStop(2);
    but from here I'm stuck.
    Thank you for your help

    What you can do is use the _visible property of the object to make it appear and disappear, or more correctly, use the opoosite of the _visible property.  You should not put code "on" objects, keep it in the timeline.
    If "object" is the instance name of the object you want to toggle, then in the timeline code you can use...
    object._visible = false;  // start with the object being invisible
    yourButtonName.onRelease = function(){
        object._visible = !object._visible;
    That one line in the function sets the object's _visible property to be the opposite of what it currently is.

    Using JNI your java classes can have methods implemented in C/C++.

  • HT3354 how can i use one table for reference to another

    how can i use a table for a referance to another eg when i type a word in a cell, i will like it to match the word with another table then return the information in the cell i am using

    you can use vlookup() (or any of the lookup family of functions) to locate an item based on a key value:
    Here is an example of something you can do with two tables:
    The table on the right is title "Data" and stores a list of names with age and favorite color.
    The table on the left uses the value in the first column to lookup up information in the table Data
    in the table on the left:
    B2=IFERROR(A2&" is " & VLOOKUP(A2, Data :: A:D, 2, 0)&" years old and likes the color "& VLOOKUP(A2, Data :: A:D, 3, 0), "NOT FOUND")
    I know this look complicated.  so I'll break it up into smalled pieces:
    first the "&" is called the concatenate operator and joins two strings.  like this:
    a string is a set of characters between double quotes.
    so "string 1" & "string 2" becomes "string 1string2"  or "Sam " & "Jones" becomes "Sam Jones"
    you can use cell references instead of strings directly in which case the concatenation is performed on the contents of the cells.
    so if cell A1 contains "Hi " and the cell A2 contains "There"  then A1 & A2 will result in "Hi There"
    so you could add the formula
    A3=A1 & A2
    this is short hand for select cell A3 then type everything including the A3 so that A3 contains "=A1 & A2" (omit the double quote)
    OK.  So the formula I provided concatenates several items together:
    it concatenates A2, then the string " is " then a formula, then the string " years old and likes the color " then a formula
    the two formulas (highlighted in blue) perform a lookup of the value in cell A2 in columns A thru D of the table named "Data".  If if finds the value in cell A2 in the first column of the lookup range in the table Data (column A) then it returns the value from the same row but in the second or third column.
    all that is in a function calld iserror() to trap the condition where the calue you enter in A2 does not exist in the table Data:
    You will find the Numbers users guide and function reference helpful.  You can download then from Apple here:

  • How can I pass a String by reference in java?

    Hello!
    My question is how to pass a String by reference in java.
    I tried to declare my variable, instead of using "String xxx = "f";", I used "String xxx = new String ("f");" :
    public static void main (String []args)
    String xxx = new String("f");
    StatusEnum result2 = getErrorPointStr(xxx);
         public StatusEnum getErrorPointStr(String text)
              StatusEnum testStatus = StatusEnum.PASS;
              StringBuffer buffer = new StringBuffer();
    buffer.append("123");
              text = buffer.toString();
              return testStatus;
    After calling to getErrorPointStr(String text) function, xxx = "f"
    So it does not work.
    How can I solve this? It is very important, the function will receive String and not something else.
    Thanks!

    Which is why I said:
    Which is why you only managed to change what 'text' referred to in the methodExcept that's not why. Even if String was mutable, doing text = whatever; would have the same effect; it would change what that variable refers to in the method, but it would not change the object's state.
    I meant that, since there was no way to actually change the data (ie the char[] or whatever) within the object 'text' referred to, the OP was attempting to change what 'text' referred to and hoping it would be reflected outside the method...which we know won't happen as Java is pass-by-value.\Ah, now I see.
    These by-value/by-reference threads tend to get confusing, because usually the person is passing a String, so the immutability of String tends to get in the way and just muddy the waters.

  • Can Evaluate function return object type

    Hi
    Evaluate function can be used to call db functions in OBIEE. I have a function which returns an object ( pl/sql table).
    Created a simple report in Oracle Answers and added following in one of the columns
    evaluate( 'get_ccid(%1)' as t_ccid , @{p_request})
    When I try to run this in Oracle answers, getting syntax error. If same function returns varchar or number it works well.

    evaluate( 'get_ccid(%1)' as t_ccid , @{p_request})Eakta, You syntax seems to be wrong here. What type of data your presentation variable contains here ?? You are saying its working fine with Number datatype..so can you try..somthing like below with some default value..
    EVALUATE('get_ccid(%1)',@{p_request}{2})
    OR
    EVALUATE('get_ccid(%1)' as varchar(250),@{p_request}{ABC})
    Also, refer

  • Can stored function return record type or cursor type?

    Hi everybody,
    I am working with a stored function now.
    Can the function output more that ONE result? i.e. cursor or record type.
    Thanks.
    Brigitta.

    Brigitta,
    If you are calling the stored function from SQL then the function can only return one of the base datatypes, as Murali has said. However, if you are calling the function from PLSQL you can return any complex datatype, eg:
    package test_package is
    type rec_test is
      ( col_a number
      , col b varchar2(30) );
    type tab_test is
      table of rec_test
      index by binary ineteger;
    function test_function (.....)
    return tab_test;
    end test_package;and to call this function:
    declare
    l_table test_package.tab_test;
    begin
    l_table := test_package.test_function(....);
    end;Hope that helps!
