Can I pass a pointer to a class?

Is there a way to copy a pointer of a data class ?
I have an event with a Student class (studentid, lastname, firstname) and I want to pass the address of the original student in the event, so that the eventListener can modify the original Student.
How can this be done?
The custom event has a var student:Student ;
when I create a new event:
var myEvent:StudentEvent = new StudentEvent('clicked');
myEvent.student = clickedStudent;
then myEvent.student is a copy of clickedStudent,
I want them to be the same object.
thanks,
steve

then myEvent.student is a copy of clickedStudent,
No it's not. It's a copy of the reference to the student.
I want them to be the same object.
They are.
clickedStudent is a pointer to the object, not the object itself.

Reg: Passing Image url through CSS Class

Hi,
How can i pass the image through Css class ?
Thanks in advance.

Hi,
I am not sure if that can be done in css file though.
I suppose you are using the backing bean for setting the skin (just read your old thread). If yes, you can add two images to your page and set the visible property according to the current skin. Something like
<af:image id="i1" source="../images/first_logo.gif" visible="#{seesionScope.currentSkin == 'First'}"/>
<af:image id="i2" source="../images/second_logo.gif" visible="#{seesionScope.currentSkin == 'Second'}"/>
If i select Second CSS file then the logo will be change according to the style class defined in First CSS file .AFAIK, the company logo would be static ;) .

How can I pass a value to the command prompt?

I was wondering how can I pass a value to the command prompt with Windows and Linux? I'm more interested in Linux's system than Windows though. Is there a way to return info from the command prompt?

Here is a snippet from http://mindprod.com/jglossexec.html that explains how in detail.
Runtime.getRuntime().exec("myprog.exe") will spawn an external process that runs in parallel with the Java execution. In Windows 95/98/ME/NT/2000/XP, you must use an explicit *.exe or *.com extension on the parameter. It is also best to fully qualify those names so that the system executable search path is irrelevant, and so you don't pick up some stray program off the path with the same name.
To run a *.BAT, *.CMD, *.html *.BTM or URL you must invoke the command processor with these as a parameter. These extensions are not first class executables in Windows. They are input data for the command processor. You must also invoke the command processor when you want to use the < > | piping options, Here's how, presuming you are not interested in looking at the output:
Runtime.getRuntime( ).exec ("command.com /E:1900 /C MyBat.bat" );
Runtime.getRuntime( ).exec ("cmd.exe /E:1900 /C MyCmd.cmd" );
Runtime.getRuntime( ).exec ("C:\\4DOS601\\4DOS.COM /E:1900 /C MyBtm.btm" );
Runtime.getRuntime( ).exec ("D:\\4NT301\\4NT.EXE /E:1900 /C MyBtm.btm" );
There are also overloaded forms of exec(),
Runtime.getRuntime( ).exec ("command.com /E:1900 /C MyBat.bat", null);
Runtime.getRuntime( ).exec ("command.com /E:1900 /C MyBat.bat", null, "C:\\SomeDirectory");
The second argument can be a String [], and can be used to set environment variables. In the second case, "C:\\SomeDirectory" specifies a directory for the process to start in. If, for instance, your process saves files to disk, then this form allows you to specify which directory they will be saved in.
Windows and NT will let you feed a URL string to the command processor and it will find a browser, launch the browser, and render the page, e.g.
Runtime.getRuntime( ).exec ("command.com http://mindprod.com/projects.html" );
Another lower level approach that does not require extension associations to be quite as well set up is:
Runtime.getRuntime( ).exec ("rundll32 url.dll,FileProtocolHandler http://mindprod.com/projects.html" );
Note that a URL is not the same thing as a file name. You can point your browser at a local file with something like this: file://localhost/E:/mindprod/jgloss.html or file:///E|/mindprod/jgloss.html.
Composing just the right platform-specific command to launch browser and feed it a URL to display can be frustrating. You can use the BrowserLauncher package to do that for you.
Note that
rundll32.exe url.dll,FileProtocolHandler file:///E|/mindprod/jgloss.html
won't work on the command line because | is reserved as the piping operator, though it will work as an exec parameter passed directly to the rundll32.exe executable.
With explicit extensions and appropriately set up associations in Windows 95/98/ME/NT/2000/XP you can often bypass the command processor and invoke the file directly, even *.bat.
Similarly, for Unix/Linux you must spawn the program that can process the script, e.g. bash. However, you can run scripts directly with exec if you do two things:
Start the script with #!bash or whatever the interpreter's name is.
Mark the script file itself with the executable attribute.
Alternatively start the script interpreter, e.g.
Runtime.getRuntime( ).exec (new String[]{"/bin/sh", "-c", "echo $SHELL"}";

Passing a float from one class to another?

ok i have an app that i have started from scratch several times on. I have a xib file containing anywhere from 3 - 10 textfields. i want to be able to pass data input in those textFeilds to another xib to display in a label, but also i want to be able to use some of that data input to also do calculations with and display those answer in additional labels on the answer.xib . i have a separate class just to store the data (datastorage.h & .m) i can successfully pass data from view1 into the datastorage and backout to view2 when the user presses the calculate button. the problem im having is that in the data storage class when im doing my calculations im using a float to hold the answer. i cant seen to find a way to push that float value from datastorage to view2. i have been searching for about 3 days now trying different things, converting the float to NSString, using an NSString instead of a float. i keep getting yellow errors no matter what i try. i even just tired a few minutes ago setting a void and float in the appdelegate, i read one forum that said you can pass a float between several viewcontrollers that way but that didnt seen to work either. does anyone have any ideas i could try? or point me in the right direction?
thanks in advance!

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.

Pointer to a class?

I have a class Dictionary
public class Dictionary
private HashMap<String, ArrayList<String>> dictionary;
private HashMap<String, ArrayList<Details>> synset;
public Dictionary()
dictionary = new HashMap<String, ArrayList<String>>();
synset = new HashMap<String, ArrayList<Details>>();
//some methods
and a class Details
public class Details
private String word;
private String type;
private String meaning;
private String w_num;
private String sense_num;
private String tag_count;
private ArrayList<String> hyponyms;
private ArrayList<String> meronyms;
public Details(String word, String type, String meaning, String w_num, String sense_num, String tag_count)
this.word = word;
this.type = type;
this.meaning = meaning;
this.w_num = w_num;
this.sense_num = sense_num;
this.tag_count = tag_count;
hyponyms = new ArrayList<String>();
meronyms = new ArrayList<String>();
The dictionary class reads a file and creates Details objects. I have a method which allows me to enter a word into the dictionary HashMap which gives an id. I can put this into the synset HashMap to retrieve it's detail object. This can is passed to the Details class where a toString() method prints the details. A detail object has two array lists, hyponyms and meronyms (related words) which give an id.
What I want to do is pass the hyponym and meronym id's back to the synset HashMap in the dictionary class and retrieve the details. It is possible by using a pointer to the synset hashmap in the Detail constructer but I don't think the Detail class should be able to access the HashMaps at this level. I want a pointer to the dictionary class itself so I can access the HashMaps using defined accessor methods. Can anyone suggest how to do this?

Details could have a method named "setDictionary" which accepts a Dictionary object, and you pass yours to it, and it keeps a reference so that it can invoke the methods when it needs to.Absolutely. In fact, if you envisage changing dictionaries at runtime, you would be well advised to provide this setter method. If a Details object must have a Dictionary to do its work, I'd still pass it in via a constructor, but there aren't any rules around this

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 a value into a page fragment?

How can I pass a value into a page fragment?
I am implementing four search screens. And the only thing different about them will be their backing bean.
So I’d like to do something like have four pages, each which retrieves its appropriate backing bean, sets that bean to a variable, and then includes a page fragment which contains the generic search page code (which will make use of that variable).
The code in the four pages would be something like this:
<?xml version='1.0' encoding='windows-1252'?>
<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="2.0"
xmlns:c="http://java.sun.com/jsp/jstl/core">
<jsp:directive.page contentType="text/html;charset=windows-1252"/>
<c:set var="searchPageBackingBean"
value="#{pageFlowScope.employeeSearchPageBean}"
scope="page"/>
<jsp:include page="./SearchPageBody.jsff"/>
</jsp:root>
At this point, what I’m seeing is that the fragment page, SearchPageBody.jsff, has no visibility of the searchPageBackingBean variable, either referencing it as #{pageFlowScope.searchPageBackingBean} or just #{searchPageBackingBean}

The following will work, assuming you are needing to access a managed bean:
Put this in the parent page:
<c:set var="nameOfSearchPageBackingBean"
value="employeeSearchPageBean"
scope="request"/>
Put this in the child, SearchPageBody.jsff:
<c:set var="searchPageBean"
value="#{pageFlowScope[nameOfSearchPageBackingBean]}"
scope="page"/>

How can we pass the select-option value to modulepool program?

hi,
how can we pass the select-option value to modulepool program ?
Because if i declared select-options in executable program and i used SSCRFIELDS to define push buttons in selection screen.
           My requirement if enter the values to select-options and press UPDATE pussbotton then i want call screen which contains tablecontrol.
           How i get select-option values to PAI of call screen for getting the data from database table to my internal table?

Oh I thought that you have selection-screen and again you are working on dialog programming.
if you want to use select-option directly in module pool then it is not possible.
but you can do other way.
create two varaiables
data : v_kun_low like kna1-kunnr,
         v_kun_high like kna1-kunnr.
use these two variables in layout ,let user knows that he can not give options like gt,lt,eq ,it will be always BT.
and also when you see normal report program,you can use multiple values in either low or high,but here it is not possibel.
use can enter only low value and high value.
when you come to program point of view
declare one range
ranges r_kunnr for kna1-kunnr.
do the coding like
r_kunnr-low = v_kun_low.
r_kunnr-high = v_kun_high.
r_kunnr-options = 'BT'.
r_kunnr-sign = 'I'.
append r_kunnr.
now you can use r_kunnr in select query ,it will work like select-option.
other than this there is no option.
Thanks

How do I create a 1d array that takes a single calculation and insert the result into the first row and then the next calculation the next time the loop passes that point and puts the results in thsecond row and so on until the loop is exited.

The attached file is work inprogress, with some dummy data sp that I can test it out without having to connect to equipment.
The second tab is the one that I am having the problem with. the output array from the replace element appears to be starting at the index position of 1 rather than 0 but that is ok it is still show that the new data is placed in incrementing element locations. However the main array that I am trying to build that is suppose to take each new calculation and place it in the next index(row) does not ap
pear to be working or at least I am not getting any indication on the inidcator.
Basically what I am attempting to do is is gather some pulses from adevice for a minute, place the results for a calculation, so that it displays then do the same again the next minute, but put these result in the next row and so on until the specifiied time has expired and the loop exits. I need to have all results displayed and keep building the array(display until, the end of the test)Eventually I will have to include a min max section that displays the min and max values calculated, but that should be easy with the min max function.Actually I thought this should have been easy but, I gues I can not see the forest through the trees. Can any one help to slear this up for me.

I didn't really have time to dig in and understand your program in depth,
but I have a few tips for you that might things a bit easier:
- You use local variables excessively which really complicates things. Try
not to use them and it will make your life easier.
- If you flowchart the design (very similar to a dataflow diagram, keep in
mind!) you want to gather data, calculate a value from that data, store the
calculation in an array, and loop while the time is in a certain range. So
theres really not much need for a sequence as long as you get rid of the
local variables (sequences also complicate things)
- You loop again if timepassed+1 is still less than some constant. Rather
than messing with locals it seems so much easier to use a shiftregister (if
absolutely necessary) or in this case base it upon the number of iterations
of the loop. In this case it looks like "time passed" is the same thing as
the number of loop iterations, but I didn't check closely. There's an i
terminal in your whileloop to read for the number of iterations.
- After having simplified your design by eliminating unnecessary sequence
and local variables, you should be able to draw out the labview diagram.
Don't try to use the "insert into array" vis since theres no need. Each
iteration of your loop calculates a number which goes into the next position
of the array right? Pass your result outside the loop, and enable indexing
on the terminal so Labview automatically generates the array for you. If
your calculation is a function of previous data, then use a shift register
to keep previous values around.
I wish you luck. Post again if you have any questions. Without a more
detailed understanding of your task at hand it's kind of hard to post actual
code suggestions for you.

Can i pass an int * to a native function?

From Java, can I pass an int pointer to the JNI?
I want the native function to assign data to an int in the Java program.
Many thanks!

838478 wrote:
Many thanks to both of you for your helpful responses. I pitched my original question somewhat disingenuously in order to be precise. My actual development issue is broader:
I have C++ API that passes many data types by reference (as pointers or references) in order to modify the passed values. If I were to wrap this API to call it from from Java it sounds as though passing each parameter as an object (e.g. Integer for int would be the cleanest way to go. Does this sound correct?
One enigma: I have to call a native function with a char * argument that returns with that char * pointing to a buffer of binary data. How should I pass back that binary buffer to Java? As a String? Your problem is not specific enough.
1. You want to create data, regardless of the type, on the native heap and pass it through java to another native method. Solution: Use a long. You have a pointer to the data (again the type does NOT matter), you cast it to a long, you return that from your first method, pass it into the second, and there you cast the long back to the pointer. The pointer can point to anything you like including complex data types.
2. You want to create data, of some complex structure, on the native heap and then access that data in java. Then you MUST map it to java types, every piece of data, of every type, specific to the type. So a native int maps to a java int (if the sizes match), a char* maps to a String, etc. You MUST create in some fashion every java data item that you need. There are NO shortcuts.

How can I pass the value to another frame?

Hi all,
The following is part of my coding of a frame. Once i click on the jButton2, the selected value will be stored into a variable named NAME and the value will be displayed by a label in same frame. At the same time, a new frame named TESTING3 will be set to visible.
private void jButton2ActionPerformed(java.awt.event.ActionEvent evt)
// TODO add your handling code here:
    String name = (String)jList1.getSelectedValue();
    jLabel1.setText(name);       //display the value in a label in same frame
    new testing3().setVisible(true);     //a new frame set to visible
}      Question: How can I pass the value to TESTING3 frame and display it on that frame?
Thanks,
ning.

just make an archive that save that variable and them get them from de clase were you save it
public class sav {
String n;
public sav {
n="";
public void addn(String x){
n=x;
public String shown(){
return n;
and them save it from the frame
sav sun = new sav();
sav.addn(f);
them call it from the other frame
sav sin = new sav();
String s = sin.shown();
label.setText(s);
and i think thats you want to do if its not please explain me better

How to pass a variable from one class to another class?

Hi,
Is it possible to pass a variable from one class to another? For e.g., I need the value of int a for calculation purpose in method doB() but I get an error <identifier> expected. What does the error mean? I know, it's a very, very simple question but once I learn this, I promise to remember it forever. Thank you.
class A {
int a;
int doA() {
      a = a + 1;
      return a;
class B {
int b;
A r = new A();
r.a; // error: <identifier> expected. What does that mean ?
int doB() {
     int c = b/a; // error: operator / cannot be applied to a
}Thank you!

elaine_g wrote:
I am wondering why does (r.a) give an error outside the method? What's the reason it only works when used inside the (b/r.a) maths function? This is illegal syntax:
class B {
int b;
A r = new A();
r.a; //syntax error
}Why? Class definition restricts what you can define within a class to a few things:
class X {
    Y y = new Y(); //defining a field -- okay
    public X() { //defining a constructor -- okay
    void f() { //defining a method -- okay
}... and a few other things, but you can't just write "r.a" there. It also makes no sense -- that expression by itself just accesses a field and does nothing with it -- why bother?
This is also illegal syntax:
int doB() {
      A r = new A();
      r.a; // error: not a statement
}Again, all "r.a" does on its own is access a field and do nothing with it -- a "noop". Since it has no effect, writing this indicates confusion on the part of the coder, so it classified as a syntax error. There is no reason to write that.

Passing a parameter from one class to another class in the same package

Hi.
I am trying to pass a parameter from one class to another class with in a package.And i am Getting the variable as null every time.In the code there is two classes.
i. BugWatcherAction.java
ii.BugWatcherRefreshAction.Java.
We have implemented caching in the front-end level.But according to the business logic we need to clear the cache and again have to access the database after some actions are happened.There are another class file called BugwatcherPortletContent.java.
So, we are dealing with three java files.The database interaction is taken care by the portletContent.java file.Below I am giving the code for the perticular function in the bugwatcherPortletContent.java:
==============================================================
public Object loadContent() throws Exception {
Hashtable htStore = new Hashtable();
JetspeedRunData rundata = this.getInputData();
String pId = this.getPorletId();
PortalLogger.logDebug(" in the portlet content: "+pId);
pId1=pId;//done by sraha
htStore.put("PortletId", pId);
htStore.put("BW_HOME_URL",CommonUtil.getMessage("BW.Home.Url"));
htStore.put("BW_BUGVIEW_URL",CommonUtil.getMessage("BW.BugView.Url"));
HttpServletRequest request = rundata.getRequest();
PortalLogger.logDebug(
"BugWatcherPortletContent:: build normal context");
HttpSession session = null;
int bugProfileId = 0;
Hashtable bugProfiles = null;
Hashtable bugData = null;
boolean fetchProfiles = false;
try {
session = request.getSession(true);
// Attempting to get the profiles from the session.
//If the profiles are not present in the session, then they would have to be
// obtained from the database.
bugProfiles = (Hashtable) session.getAttribute("Profiles");
//Getting the selected bug profile id.
String bugProfileIdObj = request.getParameter("bugProfile" + pId);
// Getting the logged in user
String userId = request.getRemoteUser();
if (bugProfiles == null) {
fetchProfiles = true;
if (bugProfileIdObj == null) {
// setting the bugprofile id as -1 indicates "all profiles" is selected
bugProfileIdObj =(String) session.getAttribute("bugProfileId" + pId);
if (bugProfileIdObj == null) {
bugProfileId = -1;
else {
bugProfileId = Integer.parseInt(bugProfileIdObj);
else {
bugProfileId = Integer.parseInt(bugProfileIdObj);
session.setAttribute(
("bugProfileId" + pId),
Integer.toString(bugProfileId));
//fetching the bug list
bugData =BugWatcherAPI.getbugList(userId, bugProfileId, fetchProfiles);
PortalLogger.logDebug("BugWatcherPortletContent:: got bug data");
if (bugData != null) {
Hashtable htProfiles = (Hashtable) bugData.get("Profiles");
} else {
htStore.put("NoProfiles", "Y");
} catch (CodedPortalException e) {
htStore.put("Error", CommonUtil.getErrMessage(e.getMessage()));
PortalLogger.logException
("BugWatcherPortletContent:: CodedPortalException!!",e);
} catch (Exception e) {
PortalLogger.logException(
"BugWatcherPortletContent::Generic Exception!!",e);
htStore.put(     "Error",CommonUtil.getErrMessage(ErrorConstantsI.GET_BUGLIST_FAILED));
if (fetchProfiles) {
bugProfiles = (Hashtable) bugData.get("Profiles");
session.setAttribute("Profiles", bugProfiles);
// putting the stuff in the context
htStore.put("Profiles", bugProfiles);
htStore.put("SelectedProfile", new Integer(bugProfileId));
htStore.put("bugs", (ArrayList) bugData.get("Bugs"));
return htStore;
=============================================================
And I am trying to call this function as it can capable of fetching the data from the database by "getbugProfiles".
In the new class bugWatcherRefreshAction.java I have coded a part of code which actually clears the caching.Below I am giving the required part of the code:
=============================================================
public void doPerform(RunData rundata, Context context,String str) throws Exception {
JetspeedRunData data = (JetspeedRunData) rundata;
HttpServletRequest request = null;
//PortletConfig pc = portlet.getPortletConfig();
//String userId = request.getRemoteUser();
/*String userId = ((JetspeedUser)rundata.getUser()).getUserName();//sraha on 1/4/05
String pId = request.getParameter("PortletId");
PortalLogger.logDebug("just after pId " +pId); */
//Calling the variable holding the value of portlet id from BugWatcherAction.java
//We are getting the portlet id here , through a variable from BugWatcherAction.java
/*BugWatcherPortletContent bgAct = new BugWatcherPortletContent();
String portletID = bgAct.pId1;
PortalLogger.logDebug("got the portlet ID in bugwatcherRefreshAction:---sraha"+portletID);*/
// updating the bug groups
Hashtable result = new Hashtable();
try {
request = data.getRequest();
String userId = ((JetspeedUser)data.getUser()).getUserName();//sraha on 1/4/05

===============================================================
In the bugwatcher Action there is another function called PostLoadContent.java
here though i have found the portlet Id but unable to fetch that in the bugWatcherRefreshAction.java . I am also giving the code of that function under the bugWatcherAction.Java
================================================
// Get the PortletData object from intermediate store.
CacheablePortletData pdata =(CacheablePortletData) PortletCache.getCacheable(PortletCacheHelper.getUserHandle(
//rundata.getRequest().getRemoteUser()));
((JetspeedUser)rundata.getUser()).getUserName()));
pId1 = (String)portlet.getID();
PortalLogger.logDebug("in the bugwatcher action:"+pId1);
try {
Hashtable htStore = null;
// if PortletData is available in store, get current portlet's data from it.
if (pdata != null) {
htStore =(Hashtable) pdata.getObject(     PortletCacheHelper.getUserPortletHandle(
((JetspeedUser)rundata.getUser()).getUserName(),portlet.getID()));
//Loop through the hashtable and put its elements in context
Set storeKeySet = htStore.keySet();
Iterator itr = storeKeySet.iterator();
while (itr.hasNext()) {
String paramName = (String) itr.next();
context.put(paramName, htStore.get(paramName));
bugwatcherRefreshAction bRefAc = new bugwatcherRefreshAction();
bRefAc.doPerform(pdata,context,pId1);
=============================================================
So this is the total scenario for the fetching the data , after clearing the cache and display that in the portal.I am unable to do that.Presently it is still fetching the data from the cache and it is not going to the database.Even the portlet Id is returning as null.
I am unable to implement that thing.
If you have any insight about this thing, that would be great .As it is very urgent a promt response will highly appreciated.Please send me any pointers or any issues for this I am unable to do that.
Please let me know as early as possible.
Thanks and regards,
Santanu Raha.

Have you run it in a debugger? That will show you exactly what is happening and why.

Can I pass a pointer to a class?
