Mixed/Double cache event listener events
Hi all,
Doing some very basic testing here now as we see what we can only assume to be strange behaviour.
Let's start with something simple:
package com.test;
import com.tangosol.net.CacheFactory;
import com.tangosol.net.NamedCache;
import com.tangosol.util.MapEvent;
import com.tangosol.util.MapListener;
public class RunKeyListener1 {
public static void main(String... args) {
NamedCache myCache = CacheFactory.getCache("my-cache");
myCache.addMapListener(new MapListener() {
@Override
public void entryUpdated(MapEvent event) {
System.out.println("Key Update: Old: " + event.getOldValue() + ", New: " + event.getNewValue());
@Override
public void entryInserted(MapEvent event) {
System.out.println("Key Insert: Old: " + event.getOldValue() + ", New: " + event.getNewValue());
@Override
public void entryDeleted(MapEvent event) {
System.out.println("Key Delete: Old: " + event.getOldValue() + ", New: " + event.getNewValue());
}, "Key1", false);
myCache.put("Key1", 1L);
myCache.put("Key1", 2L);
myCache.remove("Key1");
Running this with default settings we get as expected this output:
Key Insert: Old: null, New: 1
Key Update: Old: 1, New: 2
Key Delete: Old: 2, New: null
All good so far, so let's add another listener on the same node, but now let's do a simple event transformer (which doesn't do anything actually):
Event transformer code:
package com.test;
import com.tangosol.util.MapEvent;
import com.tangosol.util.MapEventTransformer;
public class VoidTransformer implements MapEventTransformer {
@Override
public MapEvent transform(MapEvent event) {
Object oldValue = event.getOldValue();
Object newValue = event.getNewValue();
MapEvent newEvent = new MapEvent(event.getMap(), event.getId(),
event.getKey(), oldValue, newValue);
return newEvent;
Updated test code:
package com.test;
import com.tangosol.net.CacheFactory;
import com.tangosol.net.NamedCache;
import com.tangosol.util.MapEvent;
import com.tangosol.util.MapListener;
import com.tangosol.util.extractor.IdentityExtractor;
import com.tangosol.util.filter.LessFilter;
import com.tangosol.util.filter.MapEventFilter;
import com.tangosol.util.filter.MapEventTransformerFilter;
public class RunKeyListener2 {
public static void main(String... args) {
NamedCache myCache = CacheFactory.getCache("my-cache");
myCache.addMapListener(new MapListener() {
@Override
public void entryUpdated(MapEvent event) {
System.out.println("Key Update: Old: " + event.getOldValue() + ", New: " + event.getNewValue());
@Override
public void entryInserted(MapEvent event) {
System.out.println("Key Insert: Old: " + event.getOldValue() + ", New: " + event.getNewValue());
@Override
public void entryDeleted(MapEvent event) {
System.out.println("Key Delete: Old: " + event.getOldValue() + ", New: " + event.getNewValue());
}, "Key1", false);
MapEventFilter mapEventFilter = new MapEventFilter(MapEventFilter.E_ALL, new LessFilter(IdentityExtractor.INSTANCE, 50L));
MapEventTransformerFilter transformerFilter = new MapEventTransformerFilter(mapEventFilter, new VoidTransformer());
myCache.addMapListener(new MapListener() {
@Override
public void entryUpdated(MapEvent event) {
System.out.println("Filter Update: Old: " + event.getOldValue() + ", New: " + event.getNewValue());
@Override
public void entryInserted(MapEvent event) {
System.out.println("Filter Insert: Old: " + event.getOldValue() + ", New: " + event.getNewValue());
@Override
public void entryDeleted(MapEvent event) {
System.out.println("Filter Delete: Old: " + event.getOldValue() + ", New: " + event.getNewValue());
}, transformerFilter, false);
myCache.put("Key1", 1L);
myCache.put("Key1", 2L);
myCache.remove("Key1");
I would expect the output from this to be:
Key Insert: Old: null, New: 1
Filter Insert: Old: null, New: 1
Key Update: Old: 1, New: 2
Filter Update: Old: 1, New: 2
Key Delete: Old: 2, New: null
Filter Delete: Old: 2, New: null
Instead I get this:
Filter Insert: Old: null, New: 1
Key Insert: Old: null, New: 1
Filter Insert: Old: null, New: 1
Key Insert: Old: null, New: 1
Filter Update: Old: 1, New: 2
Key Update: Old: 1, New: 2
Filter Update: Old: 1, New: 2
Key Update: Old: 1, New: 2
Filter Delete: Old: 2, New: null
Key Delete: Old: 2, New: null
Filter Delete: Old: 2, New: null
Key Delete: Old: 2, New: null
Similarly, changing the filtered listener to a lite listener this is the output:
Key Insert: Old: null, New: null
Filter Insert: Old: null, New: null
Key Insert: Old: null, New: 1
Filter Insert: Old: null, New: 1
Key Update: Old: null, New: null
Filter Update: Old: null, New: null
Key Update: Old: 1, New: 2
Filter Update: Old: 1, New: 2
Key Delete: Old: null, New: null
Filter Delete: Old: null, New: null
Key Delete: Old: 2, New: null
Filter Delete: Old: 2, New: null
Seems like the events are doubling up. Any clues?
All running with default config and 3.7.1.4.

Error trying to register a Java event listener
I'm trying to register a java event listener in 11g with the following piece of code:
DECLARE
b BOOLEAN := FALSE;
BEGIN
b := DBMS_XDB.createFolder('/public/resconfig');
b := DBMS_XDB.createResource(
'/public/resconfig/hr_event.xml',
'<ResConfig xmlns="http://xmlns.oracle.com/xdb/XDBResConfig.xsd"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.oracle.com/xdb/XDBResConfig.xsd
http://xmlns.oracle.com/xdb/XDBResConfig.xsd">
<event-listeners default-language="Java">
<listener>
<description>Category application</description>
<schema>HR</schema>
<source>xdbproject.OpenOfficeEventHandler</source>
<language>Java</language>
<events>
<Post-Create/>
<Post-LinkIn/>
</events>
</listener>
</event-listeners>
<defaultChildConfig>
<configuration>
<path>/public/resconfig/hr_event.xml</path>
</configuration>
</defaultChildConfig>
</ResConfig>');
END;
This results in the following error message
ORA-31146: Ugyldig lytterkilde HR.xdbproject.OpenOfficeEventHandler
ORA-06512: ved "XDB.DBMS_XDB", line 174
ORA-06512: ved line 5
which translates to Invalid listener source.
My class is loaded in the HR schema, and implements the XDBRepositoryEventListener
Does anybody have a suggestion to what I'm doing wrong, or how I can find out what makes my class invalid as a listener source?Check if it validates against the restrictions set in the XML Schema (Appendix A, Oracle XMLDB Developers Guide):

How to write a multi threaded Cache Event Listener
I have a distributed data cache called tokenCache for my application. I have also added a mapListener to this cache to listen to a particular kind of events.
tokenCache.addMapListener((MapListener) new TokenCacheListenerBean(), new MapEventFilter(tokenFilter), false);
So bascially everytime a token (The domain object of this cache) is updated the entryUpdated() method in my EJB TokenCacheListenerBean is invoked.
The issue I have though is that, from what I observe on running my code is that the Cache Listener is single threaded. So if two Token Objects on my tokenCache are updated,
lets say Token Object A and Token Object B one after the other, the entryUpdated() method in my EJB is invoked for Token Object A and once the invocation is complete
then the entryUpdated() method is invoked again for Token Object B(). At a given point of time there is only one instance of TokenCacheListenerBean EJB. Is there a way to
make this happen in multi-threaded manner ?
Is there a configuration setting somewhere which allows multiple CacheListeners to be instantiated at a given point of time ?

asdlCache.remove(asdlID);
jcaBean.provision(provisionAsdl, newToken.getTokenID());
logger.info(ConnectionManager.printTokenCache());
logger.info(printASDLCache());
}Here is what I am asking!
I have added 2 listeners (Listener A and Listener B) which each listen on for changes made to 2 different token Cache Objects (Token A and Token B).
for (i = 0; i < 2 ; i++) {
Token tokenAdded = new Token(UUID.randomUUID().toString(),TOKEN_AVAILABLE, networkID);
tokenCache.put(tokenAdded.getTokenID(), tokenAdded);
tokenCache.addMapListener((MapListener) new TokenCacheListener(), tokenAdded.getTokenID(), false);
Now assume that updates are made to Token A and Token B simuntaneosly.
Why do i observe in my diagnostic messages that only one Listener is invoked at a given point of time.
Which means I see Listener A getting invoked and then once invocation of Listener A is complete I see Listener B bieng invoked.
Ideally I would want both listeners to be invoked simultaneously rather than in a one off fashion.
Here is the code for my token cache Listener

Hello guys,
I'm working in a project with HTML5 and Cache Manifest for Android or IOS device. The files was cached nicely for both devices, but, when I add event listener to the cache application on android device, it doesn't callback and the cache status stay 0.
My code example is: http://gist.github.com/felipehaack/c858e416e7187763739d
I really appreciate some helpI've sent this to our test team and they're taking a peek. I know we tested it in the past and it worked.

Adding an event listener to combo box
I am working on a mortgage calculator and I cannot figure out how to add an event listener to a combo box.
I want to get the mortgage term and interest rate to calucate the mortgage using the combo cox. Here is my program.
Modify the mortgage program to allow the user to input the amount of a mortgage
and then select from a menu of mortgage loans: 7 year at 5.35%, 15 year at 5.50%, and
30 year at 5.75%. Use an array for the different loans. Display the mortgage payment
amount. Then, list the loan balance and interest paid for each payment over the term
of the loan. Allow the user to loop back and enter a new amount and make a new
selection, with resulting new values. Allow user to exit if running as an application
(can't do that for an applet though).

public static void main(String[] arguments) {
MortgageCalculator mor = new MortgageCalculator();The OP already did this to both JComboBoxes.
mochatay, here is a new actionPerformed method for you to use.
I've improved a few things here and there...
1) You can't just cast the ActionEvent's source into a JComboBox!
What if it was a JButton that fired the event? Then you would get ClassCastExceptions (I'm sure you did)
So check for all options, what the source of the ActionEvent actually was...
2) You can't assume the user will always type in valid data.
So enclose the Integer and Double parse methods in try-catch brakcets.
Then you can do something when you know that the user has entered invalid input
(like tell him/her what a clumsy idiot they are !)
3) As soon as user presses an item in any JComboBox, just re-calculate.
I did this here by programmatically clicking the 'Calculate' button.
Alternatively, you could have a 'calculate' method, which does everything inside the
if(command==calculateButton) if-block.
This will be called when:
a)calculateButton is pressed
b)when either of the JComboBoxes are pressed.
public void actionPerformed (ActionEvent event)
Object command = event.getSource ();
if (command == calculateButton) //calculates mortgage payment
int year = 0;
double rate = 0;
double mortgage = 0;
double interest = 0;
/* If user has input invalid data, tell him so
and return (Exit from this method back to where we were before */
try
year = Integer.parseInt (mortgageTerm.getSelectedItem ().toString ());
rate = new Double (interestRate.getSelectedItem ().toString ()).doubleValue ();
mortgage = new Double (mortgageAmount.getText ()).doubleValue ();
interest = rate / 100.0 / 12.0;
catch (NumberFormatException nfe)
/* Display a message Dialogue box with a message */
JOptionPane.showMessageDialog (this, "Error! Invalid input!");
return;
double monthly = mortgage * (interest / (1 - Math.pow (interest + 1, -12.0 * year)));
NumberFormat myCurrencyFormatter;
myCurrencyFormatter = NumberFormat.getCurrencyInstance (Locale.US);
monthlyPayment.setText (myCurrencyFormatter.format (monthly));
else if (command == clearButton) //clears all text fields
/* Better than setting it to null (I think) */
mortgageAmount.setText ("");
//mortgageTerm.setText(null);
//interestRate.setText(null);
monthlyPayment.setText ("");
else if (command == exitButton) //sets exit button
System.exit (0);
else if (command == mortgageTerm)
/* Programmatically 'clicks' the button,
As is user had clicked it */
calculateButton.doClick ();
else if (command == interestRate)
calculateButton.doClick ();
//JComboBox mortgageTerm = (JComboBox) event.getSource ();
//String termYear = (String) mortgageTerm.getSelectedItem ();
}Hope this solves your problems.
I also hope you'll be able to learn from what I've indicated, so you can use similar things yourself
in future!

I'm having some trouble trying to figure out how this event listener will work.
The main application is building an arrayCollection of a calendarDay custom components which is displayed by a DataGroup.
Within each calendarDay custom component i may create an arrayList of a DriverDetailComponent custom components displayed within the calendarDay by a DataGroup.
If a user double clicks on the DriverDetailComponent that is two layers in I would like to change states of the main application. I'm having trouble figuring out what item in the main application to set the listener on. Please help.
I can't figure out how to post the below as scrollable code snips so this is very long.

Event Listener dispatcher giving an ClassCast Exception in C++ 3.6.1
Hi,
I have attached a Event listener to underlying NamedCache and when I update the cache entry I didn't get any alerts. But When I checked the
coherence log I found following Exception available. But I'm not doing any sort of Casting as mentioned below.

Only difference of above exception coming program is this c++ library is loaded true JNI and relevant event listener is added during a JNI method call. Please explain me why this exception is coming. I have attached the relevant code as well.

Error ocurring when Event Listener methode in "for statement" is called
Hy guys,
I would be gratefull if somebody could answer me how can I
call a method from flex in "for statement", that is actually in my
remote service implemented. I call the method loadAssetsResult()
(event listener method in my action script) and get a collection of
objects back. In the same method I want to iterate throught this
collection and call another method from remote service, that is
specified for this object. Problem is when I call this remote
method inside of this loop statement. I get the error when I write
my code like following one:
public function loadAssetsResult(event:ResultEvent):void {
for (i=0; i<event.result.length; i++) {
a = new Asset();
a.longName = event.result
.longName;
a.shortName = event.result.shortName;
a.isin = event.result
.isin;
a.nsin = event.result.nsin;
a.currentDayClose = event.result[0].currentQuote.dayClose;
//Schluskurs
assets.addItemAt(a, i);
RO.getIndicatorCollection(i);
DataBinding();
When I comment the row: RO.getIndicatorCollection() it works,
of course without these additional data that I get from that
method. I need to call this method inside loop statement (for each
object), but I don't know how, without getting this error?
please somebody help me with some ideas
br
SheilaKris,
First of all you should increase the value of logging-config/character-limit element in tangosol-coherence.xml to see the message entirely. The default setting is 4096 which is not enough to see your exception text.
When you do that I believe you will see that the actual exception is java.lang.ClassNotFoundException indicating that the node that has the listener installed doesn't know about the class that is being put into the cache and could be easily fixed as shown here: http://www.tangosol.com/faq-coherence.jsp#classnotfound
Please let me know if that doesn't help.

When I open up iphoto and click on the events tab then double click on an event, it used to show minis of all the photos in that event. Now it shows only one photo at a time. How do I get it back? Can you help?
On the bottom bar of the window (on the left iPhoto 11, on the right in other versions) note the slider. Drag it left.

I am trying to create a small game got most of the functionality, apart from one aspect how would you code an Listener event that would take into account that if any two pawns on a chessboard were on the same line in any direction then that row would become highlighted and the user could not place any more pawns on that row?
I know a wee bit about �if� and �else� statements but I have no idea how you would create code that would carry out the above function.
Any help would be great

javax.el.MethodExpression
(signature must match public void processAjaxBehavior(javax.faces.event.AjaxBehaviorEvent event) throws javax.faces.event.AbortProcessingException)
Try dropping the boolean return value & adding the throws. I'm running Apache's MyFaces and it's perfectly fine with your method signature, but maybe your JSF implementation isn't.
Also, you running with javax.faces.PROJECT_STAGE set to Development? Maybe some useful server-side error you're not seeing. You probably should also create your own ExceptionHandler to dump stack traces to the console/logs if you haven't done so already as well.
And lastly, you sure all your code's published to the server? If you're still stuck, then the best thing to do is to make this page as simple as possible, put just 1 checkbox w/o all the table/repeats/etc. to help you eliminate other possibilities.

Can't remove event listener from Image
I'm clearly missing something and would appreciate some help. I'm trying to run an event handler when an Image completes loading, then remove the handler so that it won't run again should the image be reloaded later.
The problem that I'm having is that the event handler simply wont' go away, despite calling removeEventListener on the Image object.
The following example demonstrates the problem (the example doesn't actually do anything useful...it's just the shortest example to demonstrate the problem). (To run the app, you'll have to provide any ol' JPEG file named "myImage.jpg" in the "src" directory of your project).
What I expect to happen is :
1) on startup, the image loads and loadComplete() runs.
2) loadComplete removes the event Listener so that subsequent re-loads won't re-fire the handler. I only want the handler to run once.
3) "loadComplete" shoudl be displayed in the Debug console.
4) A button click should display only "Changing Image" in the Debug console
What I get instead is that the loadComplete handler isn't removed, and every time I click the button, loadComplete runs when the image is re-loaded (i.e., every button click results in both "Change Image" AND "loadComplete" being displayed in the Debug console).

</mx:Application>Hi,
You can remove only event listeners that you added with the addEventListener() method in an ActionScript block. You cannot remove an event listener that was defined in the MXML tag, even if it was registered using a call to the addEventListener()method that was made inside a tag attribute.
Check this page for reference.

I'm trying to assign a mouseclick event listener to a simplebutton nested within a movie clip's later frames, starting at frame 2 and up. This card, however, is not added to my game until later, and when the player clicks on it/turns it over.
There are four files involved in this program:
#1 The main actionscript file, which corresponds to
#2 my dreamQuester .fla file.
#3 my artifactCard file movieClip's corresponding .as file,
#4 my combo1.as file corresponding to a an instance of a simpleButton named combo1 that is already
nested --and this instance is already named-- inside/as a child of said artifactCard movieclip.
What I've done so far isn't working:
In my main dreamQuester.as file, when a player clicks on an artifactCard, its MOUSE_DOWN event
listener takes them to this function (clickArtCard), where the trouble is at:
// player clicked on the artC card--which is a child of posArt1 on stage--to turn card over:
function clickArtCard(a_event:MouseEvent) {
var thisArtCard:artifactCard = (a_event.target as artifactCard);
thisArtCard.gotoAndStop(unclickedArt1); // go to frame number of artifact
// card where combo1 button is.
thisArtCard.removeEventListener(MouseEvent.CLICK,clickArtCard);
thisArtCard.buttonMode = false;
trace("combo1.combo is:" + combo1.combo);
trace("posArt1.artC.combo1 is:" + posArt1.artC.combo1);
posArt1.artC.combo1.addEventListener(MouseEvent.MOUSE_DOWN, comboClickedWHO);
when the artC card--the static public instance of artifactCard--is clicked, it only gets to the
trace("posArt1.artC.combo1 is:" + posArt1.artC.combo1); which returns this error message:
TypeError: Error #1010: A term is undefined and has no properties.
at MethodInfo-61()
So do how would I declare a static public variable of this simpleButton at the start of my main .as
file to make it defined to get a mouseDown actionListener into my pre-existing-and-named-instance
combo1 simpleButton?
perhaps there is a way, while the debug movie program is running, to click on the simpleButton and see exactly
what it's parent heirarchy is, to see the name of all parents above the simpleButton incase they are
different then what I think?
(just in case, I was hoping to squeeze a zip file containing these files to be less than 9MB incase someone was willing to look at my files to see what I've done so far, but 9 megs is just too big! even though all graphics I've imported where turned into vector graphics with trace bitmap. I wish there was a way to check the file size of each symbol in Flash CS4, here...)
Thank you so much for any help!
~EthanJust use a
stage.addEventListener(KeyboardEvent.KEY_DOWN, keyPressed);
function keyPressed(event:KeyboardEvent):void {
//trace(event.keyCode);
if(event.keyCode == ???){
// play the sound
Where I show the "???" you would replace with the keyCode for the key you want pressed for that sound. To determine the keyCode you can use the trace line that I have commented out.
Note that when testing in Flash you often need to disable the keyboard shortcuts in the Flash Player in order to be able to use alot of the keys. You will find this option in the Control menu options in the player. -
How can I check if a function is or is not called from the event listener? in Flash CS4 (AS3)
Hi,
I came across a little problem.
I put an event listener inside a for loop and the for loop inside a function.
I want the for loop to end as soon as the event listener inside the for loop calls its function.
Here is the general code for a better picture.
Code:
this.addEventListener(Event.ENTER_FRAME, function#1);
function function#1(event:Event):void{
if(something is true){
for(var i = 0; i < numOfmy_mcs; i++){
this["my_mc_"+String(i)].addEventListener(MouseEvent.CLICK, function#2);
function function#2(e:Event):void{
//do something cool here
Thank you for any help!kglad wrote:
that for-loop (if it executes), defines listeners for interactive objects. that will complete long before any object is clicked.
Well yes but it does it again and again (frames per second times seconds = number of times it goes through the code if i'm not mistaken), because it is inside a function, and through testing i found out that it works like this:
Example:
there are 5 my_mc's in my project: (my_mc_0, my_mc_1, my_mc_2, my_mc_3, my_mc_4)
if i click my_mc_0 function#2 is called and executed. BUT only after the loop finishes (i know this from tons of testing)...which is unnecessary since you cannot click two places at once. This might not be a problem in this example because i am only using 5 my_mc's buy if i use 500000000 my_mc's it would make a lot of difference.
is there a way to stop the loop if the function is called?
...maybe there is a better way to write it, the only alternative i know that works is if i manually write every single listener and this also is logical in this example but as i said next to impossible if the numbers get bigger.
-Note
I didn't specify this earlier but function#2 makes the if statement false so it wont jump back into it.
Thank you for the help I really appreciate it!

Library Cache Pin Wait Event (within the context of APEX)
Hello,
Firstly -
Oracle Version: 10.2.0.4.0
Apex Version: 3.0.1.00.08
Okay, my colleague (no really! This isn't one of those "Ahem ... A friend of mine has contracted something nasty +downstairs+..."-type questions) is having problems compiling a package (using TOAD incidentally, but it's the same in SQL Developer).
I've searched the forum and the web for a bit of help on what's maybe happening here and it appears to be related to a concurrency conflict with the package definition - from what I can understand it's a case of the package is in use by another session, therefore another session cannot alter it at the same time (which makes sense)
"What does this have to do with APEX?"... well, he is working on this package using the following methodology:
1. Compile the package body/spec (as necessary - body more often obviously)
2. run an apex page which uses the code in a process, which may or may not result in the error page being displayed
3. Making changes to the package body/spec
repeat steps 1-3 ad nauseum...
He is the only user directly accessing the schema (and the only user accessing the page via APEX too, although I appreciate this isn't quite the same thing).
I was wondering if, due to the architecture of APEX (the use of session pools etc), the state of a package might be being retained in some manner, thus resulting in this library cache pin wait event? If so, is there anything I can do to mitigate against this occurring?
p.s. the only difference I can see between this particular package and any other package in the schema is that this one interacts with blobs (including making references to the wwv_flow_files view) - with blobs being passed as parameters between procedures (thus potentially creating temporary blobs which may or may not being closed).
Any ideas?
p.p.s. there are also no DBMS_SCHEDULER jobs or anything that might potentially be running the code incidentally...

The problem seems to have 'resolved itself' over the weekend incidentally (although I don't believe anything truly resolves itself in this manner - something must have changed). -
How to get "double click" as an event in Module Pool
Dear Experts,
Being new to ABAp, I am struck in a problem.
I want to get double click as an event in my module pool program.
On the screen I have two input/output fields. The attributes of them are as below:
1) 1st I/O field Attributes:
Name: WA_AUFN-A
Dropdown: List box
Display: Resp. to DblClk = Checked
1) 2nd I/O field Attributes:
Name: IT_AUF-A
Dropdown: No drop down box
Display: Resp. to DblClk = UN- Checked
I get some data populated in 1st I/O field in list display.
My Requirement:
As I select one of the data from the 1st I/O field and double click on it, then what I want is that the same selected data
should appear in the 2nd I/O field.
So I want to know how can I capture "Double click as an event".
Can any1 help me out.
Regards
ChandanHi Chandan,
below is the explanation.
for example if u have 2 screen fields VBAK-VBELN & VBAK-VKORG.
VBAK-VBELN has some value say 1000. based on this one u have to fill VBAK_VKORG.
Data: l_f_field like HELP_INFO-DYNPROFLD,
l_f_value like vbak-vbeln.
case pick.
GET CURSOR FIELD l_f_field.
with this u will get to know on which field user is double clicked. so, in this case l_f_filed will have a value of VBAK-VBELN
if l_f_field = ''VABK-VBELN' and
l_f_value = '1000'. "this is optional, based on ur requirement
VBAK-VKORG = '0780'. "fill here
endif.
endcase.
Let me know if it is not clear.
Regards,
Prasad
