Help needed to understand JLS �15.14

Can someone please help me to understand JLS �15.14 (http://java.sun.com/docs/books/jls/third_edition/html/expressions.html#15.14), it says:
Postfix expressions include uses of the postfix ++ and -- operators. Also, as discussed in �15.8, names are not considered to be primary expressions, but are handled separately in the grammar to avoid certain ambiguities. They become interchangeable only here, at the level of precedence of postfix expressions.
PostfixExpression:
Primary
ExpressionName
PostIncrementExpression
PostDecrementExpression
Questions:
1. According to documentation above, "Primary" & "ExpressionName" are also considered as "PostfixExpression". Can someone please explain with some grammar examples?
2. The statement "They become interchangeable only here, at the level of precedence of postfix expressions." What is exactly interchangeable? Where can I find the level of precedence of postfix expressions?
Thank you for your time.

Well I wouldn't consider myself any expert in language grammars and thus I don't really want to take any position considering this spec. Even though I know how to use the ++ and -- operators, this kind of documentation always remains cryptic :)

Help needed to understand business process irrespective of SAP

Hello all,
I am an engineer with specialization in electronics and telecommunication. The topic of RFID is thus fascinating for me hence,I have been reading SAP AII for some time now. The components of RFID like tags, readers and communication between them is known to me upto some extend but the business process that SAP AII supports/ implements/ automates are new to me because of which I miss the big picture of SAP AII.
The material I have been reading on SAP AII describes many such process e.g. goods issue, goods return, slap and Ship, logistic process etc. I find it difficult to comprehend these business processes as I think they are described mainly in jargons/ terms (jargon for me) like "delivery processing", "delivery document", "Shipping document", "handling unit", "outbound and inbound process", "goods posting" and numerous similar terms. Moreover I think the explanation is SAP specific.
I feel I should take a top down approach to understand SAP AII and for this I first need to understand the business process in generic/ standard terms. Once they are clear I guess I would be able to understand SAP RFID solution.
I request you all to guide me. Am I taking the right approach? If yes please help me understand the basic business process. Pointers to some good douments or any other resource explaining standard business process will definately help.
Thank You

Hi Gaurav,
You are very correct that being a technical person you find difficulty in understanding jargon terms of SAP.
Let me explain you the scenario:
There are two sides to SAP
1) Functional - Understanding of Business Processes
Here there are two parts:
a) Business Process With Respect To SAP AII - These processes generally deals with RFID technology that happens in warehouses, disribution centers and are close to technological world. These deal only with SAP AII
b) Business Process With Respect To SAP R/3 - These processes deals with SAP AII when integrated with backend systems like SAP R/3, SAP WM or other systems. These talk about the end to end scenario of RFID. Like you pointed out, delivery processing, etc.
Understanding of Core that is part a above and a bit basics about b will be very helpful.
2) Technical - Understanding SAP AII
Here also two parts are there:
a) Understanding RFID as a technology with SAP AII - Deals with understaning technological viewpoints on RFID and mapping it to SAP AII. Example Devices, Tags, Device Controllers, Middlewares and their representation in SAP AII.
Most important is above part
b) Understanding Technological part of SAP itself - For example, ABAP, BAPI, BADI etc.
So this is how it works. You are going very correct and follow above things.
Please revert if you have any specific questions.
Thnks

Help needed in understanding the code.

Hi All,
I am just trying to understand the Java code in one Self Serice page. However, I am having tough in understanding the CO code. In the prosessRequest class, I have the below code.
oapagecontext.putTransactionValue("AddAssignmentInsertRowFlag", "N");
oaapplicationmodule.getTransaction().commit();
As soon as, oaapplicationmodule.getTransaction().commit();
gets executed, its calling some other class. Not sure what is being called, but i can see the log messages that its executing some other class which actually does the calls to DB APIs and inserting data into main tables.
Can you please explain me what is being called to make DB API calls. I would greatly appreciate your help.
Thanks in Advance!

Hi Rani,
As soon as the transaction is commited the methods in the VORowImpl Class are called.
You can check in the VORowImpl class and search for the log messages.
Thanks,

Help needed in understanding the concept of hierarchical queries

I really need help in this matter. I have a flafile containing about 4000 rows. It is from my supplier, it's structure is as follows:
create table Flatfile
(Pgroup varchar2(30),
Pclass varchar2(30),
Manufacturer varchar2(30),
Article varchar2(30),
Price Number(6,2));
Insert into Flatfile Values
('Application Software','Database Software','Oracle','Oracle 10G',115);
Insert into Flatfile Values
('Application Software','Database Software','Microsoft','MS SQL Server 2000',200);
Insert into Flatfile Values
('Application Software','Spreadsheet Software','Microsoft','Excel',100);
Insert into Flatfile Values
('Monitor','15"','Acer','Acer 15"" TFT superscreen',199);
Insert into Flatfile Values
('Monitor','15"','Sony','Sony R1500 flat',225);
Insert into Flatfile Values
('Monitor','17"','Philips','Philips Flatscreen',250);
Insert into Flatfile Values
('Monitor','19"','Viewsonic','Viewsonic PLasma Monitor',275);
Insert into Flatfile Values
('Processor','AMD','AMD','FX-55',600);
Insert into Flatfile Values
('Processor','Intel','Intel','P4 3 GHZ',399);
My goal is to make a hierarchical query with the start with and connect by clauses. From what I have read is that I need to normalize the data of the flatfile.
How do I achieve a table which I can query so that the query will represent the hierarchy that exists. Namely
Pgroup
++Pclasse
Application Software
++Database Software
++Spreadsheet Software
So a 2-level hierarchy. I'd like to understand this simple concept first. I built on the knowledge that I gain. So the questions are:
1.What do I need to do to make the table so that I can use a hierarchical query on it?
2. How should the query syntax be?
3. Is it also possible to get the data in the hierarchical query sorted asec?
I would only like to use the simple structures of the start with and connect by clauses first. I've read there are some new additions to 10G. The problem with the examples used by the tutorials is that the tables are already made so that they are suitable for hierarchical queries. I hope to understand it by this example. And take it a step further.
Sincerely,
Pete

Primarily hierarchy query serves to process tree-like structures which RDBMS simulates using through parent-child relation, often in a single table (see famoust
EMP table where employee can have the manager who is an employee at the same time).
In your case it could look like:
SQL> select pgroup, pclass from flatfile;
PGROUP                         PCLASS
Application Software           Database Software
Application Software           Database Software
Application Software           Spreadsheet Software
Monitor                        15"
Monitor                        15"

Help needed in understanding conversion alghorithm from byte to hex

Hi, I'm studying the following code:
public static char[] byteToHex(byte[] data) {
char[] retValue = new char[data.length * 2];
int value = 0;
int highIndex = 0;
int lowIndex = 0;
for (int i = 0; i < retValue.length; i++) {
    value = (data[i] + 256) % 256;
    highIndex = value >> 4;
    lowIndex = value & 0x0f;
    retValue[i * 2 + 0] = hexTable[highIndex];
    retValue[i * 2 + 1] = hexTable[lowIndex];
return retValue;
}There are few things (the most important) which I don't understand about the above code.
I understood that what's returned has got double size related to what's passed in because a char takes 16 bits while a byte takes 8.
1) I don't understand why each byte must be first added 256 and then % with 256 (returning the same value - Is this to eliminate negative values?)
2) I do understand that each byte is transformed in two hexadecimal values: one is the highIndex (first 8 bits) and the second is the lowerIndex (last 8 bits) and that each value is tranformed in its hexadecimal value from the array of hex values.
3) What I don't really understand is why the highIndex is calculated as: value >> 4
and the lowest index is calculated as value 0x0f (is this last also to eliminate negative values?)
If someone could clarify this for me, I'd be very grateful.
Thanks.
Marco

So, does this mean that we add 256 to eliminate the sign?No. You need the whole line to convert a signed byte into an int between 0 and 255.
A simpler way to do this would be
value = data[i] & 0xFF;
This moves down the higher bits so that it turnsinto lower bits. i.e. we need it to >be between 0 and
15.
Is this shifted of 4 because Math.pow(2, 4) = 16.0?Doing in this case, x >>4 is the same as x / 16
This leaves only the lowest 4 bits.Is the following what happens?There are no char values produced. Using 0000 as an example is not a good idea as you can change it in many ways and it is still 0000
>
Received as initial value:
byte: 0000 0000
What we need to obtain:
char: 0000 0000 0000 0000
The first 4 bits of the above byte are shifted of 4
positions to find the hexadecimal equivalent (if from
2 I want to get to 16 I have to do the opposite of
powering a number by 4); The last four bits of the
byte are extracted because of the '&' operator with
0x0f (which in binary is 1111 - Therefore all the '1'
are kept)?Yes.

But....Power gone?;-)
Okay back to topic: I read this from somewhere: SAP SRM enables the full range of supply and procurement activities, closing the loop from strategy stage to execution. SAP SRM will help you optimize operations and put together a world-class supply and procurement operation, with a scalable platform and an easy-to-use business user interface that enables processes in the following key areas:
For switching in SRM you must have basic knowledge of SAP enterprise buyer and SAP solution manager where as few basic knowledge of MM would also helpful. The must is Domain knowledge towards Management skills not towards MM configuration.
All The best.

Desperate help needed in understanding SPRY accordion CSS

hello everybody
like many out there im stumbling through some home/self tuition on DW. I've recently checked out the spry accordion. It all went well up to the part where I wanted to improve the outlook of the accordion. I luckily found some templates on the adobe site with an accordion with the general idea as to how I would like an accordion to look, or at least a platform for future ideas. (Design #2 at: http://www.adobe.com/devnet/dreamweaver/?view=samples )
I've had a look through the code and have found great difficulty understanding a few of the div classes that are contained within it, i.e. what they are attributed to etc.
Here is the HTML and the Spry CSS docs that I downloaded from the link above:

I'n terms of the <div class="accordion_340_tab"> i'm really not sure what these mean. I know the label title is situated within them (at least i think they are!!) but i dont quite understand what they are doing or mean. There is no reference to them in any of the code/ CSS sheets i downloaded.
Plus, i'm not quite sure what the two <div style="clear:both;"></div> are clearing.
I know these will be really basic questions and I apologise for having to trouble you but any help would be really really appreciated

Heya, I hope my response will help.
First off, I'd like to say that you are correct in being unable to find the " <div class="accordion_340_tab"> " anywhere in the project. I went through and checked all the code and couldn't find a reference anywhere. Also, I downloaded the project from your link, deleted the <div class="accordion_340_tab"> as well as the </div> right after the TELLUS PROIN EU ERAT" (as the opening div and closing div work together and must be added or deleted together) and it had absolutely no impact from what I could see in internet explorer 8 and firefox.
Therefore, I believe, that it was originally intended to do something or in fact did something but they took that out and then forgot to take out the div. Even within the internal .js file I couldn't find a reference. Maybe they forgot to upload a third stylesheet. Either way, it appears to work just fine without it.
"I'm not quite sure what the two <div style="clear:both;"></div> are clearing."
In regards to this, this div style tag is a less frequently used tag that can divide content. Do you know what the HR tag in html is? If not, try putting a <hr> tag (just like that, by itself) in your web page somewhere. HR stands for Horizontal Rule- it makes a horizontal line across the page. This div style clear both tag is basically an invisible HR that helps separate different divs or content or whatever else is on the page. Think of it as an invisible page break.
"I know the label title is situated within them (at least i think they are!!) but i dont quite understand what they are doing or mean."
You should check out some CSS tutorials for the basics, but in a nutshell I'll go ahead and explain what I believe you are having trouble with.
Let's put it this way:
HTML is the core of your web page. It is the content and substance.
CSS is the style of your web page. It is the color, alignment, and format of your page.
The "div" tag by itself is simply <div>. However, you MUST close a div tag somewhere on the page with a </div> A div tag by itself, however, will do absolutely nothing. How do you get it to do something? By making a CSS rule, the two most common of which are known as a "div id" and "div class".
The differences between div id and div class are pretty small- div id is mainly used for a div tag that will only be used once on the web page. Div classes are used for something that will be repeated, in this case, the accordion tabs.
Therefore, when you see something like <div id="content"> text blah blah blah </div>, then you know that the "text blah blah blah" is your content, and that content is being modified to the specifications of the id "content". Where is this "content" div? This is what you as the designer make (or there will already be one in a template) and can usually be found in an external STYLESHEET, which holds all of your css rules, and is then linked to the main web page's html document (where your content is) with a link tag in the header of the html, usually right after the title and before the end of the <header> tag. You will find <link href="example.css" rel="stylesheet" type="text/css" /> but with a different name in the part i put as "example.css"
Within that css document you have different things you can do. Let's say I want to make one div id and one div class. I want to name the ID "example1" and the class "example2". It would look something like this (note that you must ALWAYS start an ID with # and a class with a period)
#example1 {
width: 450px;
margin:auto;
color: #fff;
.example2 {
width: 900px;
margin: 10px;
color: #000;
I hope this helped.

Help needed in understanding GridBagLayout situation

I have a JPanel with a JInternalFrame and a few JPanels inside of it. The JPanel is using GridBagLayout.
When a user moves the JInternalFrame inside of the panel what is happening exactly? How is it moving the frame with relation to the Layout? It doesn't appear to be bound by the Layout. When the user drags the frame to a new location what methods are being invoked?

Having looked at the JXMapViewer which extedns XJPanel and XJPanel extends JPanel.
so if you want to get notified you need to add ComponentListener to the instance of JXMapViewer to get notificed when the following happens

Help need to understand After Effects Rendering

Hi There
I have just built my first editing pc.
I want to do Editing in Premiere and AE.
I understand it is best to share the load over 3 drives, and so i have
C: SSD - OS/programs
H: 1 TB HDD - media
F: 500GB EXternal Hard drive - renders
in premiere pro i have made it so i read of the media of H: and render to F:
BUT in after effects i am having trouble understand all this disk cache and confirmed media cache business.
I want to have my renders/previews go onto F: as i dont want my SSD to full up!
what i want to know is where do i allocate the disk cache, confirmed media cache, and the data base stuff.
or does after effects delete renders itsself afterwards.
if anyone could help or give me a simple answer as to what these disk cache and media cache things are in AE that would be amazing
Also when i hit space bar to play in AE it goes green for a few seconds then it leaves the bar behind blue!
dont understand
would appriciate any hep

Thank for for all your help.
So tell me if im now right.
When working in AE, I should:
1.Import media that is on its own drive (in this case H:)
2. Have my disk cache set on the SSD (C:) and maybe put it at a limit of 5-10 gb if I dont want it to take up much room.
3. Not worry about ram previews taking up space as they only occupy my 8gb of ram temporarily, whilst im working in AE.
4. Export/Render to My other drive (F:) when done.
Has my understanding improved?... or am I still being a wally.
Regards

Help needed in understanding the Java code.

Hi All,
I have recently started learning the Java language. I came across this example and had a problem in understanding the output of the program. I could follow that if the continue statement is present in the below program the output is "Found 9 p's in the string" . But if the continue statement is removed I could not understand why the output would be "Found 35 p's in the string" .Is it because of the spaces and characters other than p... (eter ier icked a eck of ickled eers)
Example-----------------------
The continue statement skips the current iteration of a for, while , or do-while loop. The unlabeled form skips to the end of the innermost loop's body and evaluates the boolean expression that controls the loop. The following program, ContinueDemo , steps through a String, counting the occurences of the letter "p". If the current character is not a p, the continue statement skips the rest of the loop and proceeds to the next character. If it is a "p", the program increments the letter count.
class ContinueDemo {
public static void main(String[] args) {
String searchMe
= "peter piper picked a " +
"peck of pickled peppers";
int max = searchMe.length();
int numPs = 0;
for (int i = 0; i < max; i++) {
// interested only in p's
if (searchMe.charAt(i) != 'p')
continue;
// process p's
numPs++;
System.out.println("Found " +
numPs + " p's in the string.");
Here is the output of this program:
Found 9 p's in the string.
To see this effect more clearly, try removing the continue statement and recompiling. When you run the program again, the count will be wrong, saying that it found 35 p's instead of 9.

The answer is already in your example - "The unlabeled form skips to the end of the innermost loop's body and evaluates the boolean expression that controls the loop."
It unloads the current loop iteration when condition is matching. Loop is again starting from boolean expression inside loop declaration.

Help needed in understanding what Python is and ho...

Hi All,
I have read about python and i dont quite grasp the entire technical language behind it but there are some apps that i would like to install on my E71 but they require python. I have tried to download python form sourceforge but it has never worked. Thank you all for your assistance.
Solved!
Go to Solution.

Python is an interpreted programming language.
For Python applications to run, you need to install the Python runtime first.
For the E71, download the SIS file for S60 3rd Edition or S60 3rd Edition Feature Pack 1 (FP1) from:
http://sourceforge.net/project/showfiles.php?group_id=154155&package_id=171153&release_id=644640

Help needed to understand Threads and GC

I have a question about threads
I have a class where my main method is written
public class Main {
    public static void main(String[] args) {
        SomeObject someobject = new SomeObject();
        ThreadClass obj = new ThreadClass();
        obj.set(someobject);
        Thread t1 = new Thread(obj);
        t1.setName("MyThread");
        t1.start();
}Another class
public class SomeObject
    String name = "xyz";
    public void doSomething()
        System.out.println("Done");
}And a runnable class
public class ThreadClass implements Runnable
    SomeObject temp;
    public void set(SomeObject fsTemp)
        temp = fsTemp;
    public void run()
        while(true)
            System.out.println(temp.name);
            temp.doSomething();
            try{Thread.sleep(100);}catch(Exception e){}
}Now when I run this application, once the thread is started "MyThread" the main thread would die, I want to know that if the main thread dies, will the objects created in the main method will be garbage collected??

First of all think yourself: Did you try to run your application? What happened? ?What is the conclusion? Is the Thread object garbage collected?
If you answered the questions above:
Thread objects are kind of special. A reference to the Thread object still exists when the Thread still runs (the run method is executed). This is done because stopping a Thread during its execution is not at all secure. Whenever the run method ends (the Thread is done) the garbage collector will remove the Thread object and all the references needed in there.

Help needed to understand GOTC in Time Evaluation

Hi,
I've been trying to get GOTC to work in Time Evaluation and haven't been successful. I've spent weeks on this. I've checked all the related documentation and posts but they do not help.
My requirement is: at the end of a week, differences of planned working hours and actual working hours are calculated and if the hours are greater than 0, GOTC will be triggered. I'm copying the standard rule TPO7.
As you can see, I put in the hours using operation HRS and trigger the retrocalculation while using time type 0928. Time type 0928 has the day balance set as without cancellation.
I've then configured it so that the retrocalculation will take place on a Sunday, if the condition is met.
On Monday of the same week when retrocalculation is triggered, I do not see 0928 in the internal table TES at all. According to the documentation, my time type 0928 should increase by the number I've set via HRS and I could also access it from the table TES on the Monday, but this doesn't happen.
Does anyone have any ideas? What am I doing wrong?
Thanks in advance.

Hi Jack,
did you go through my blog on GOTC.
http://aspireopenmic.com/2013/06/27/sap-time-evaluation-correct-weekly-overtime/
I am using this function to go to beginning of the work week. So in your case on the last day of the work week, when you determine the difference of planned vs. actual is > 0 then store this in a time type (daily balance) and trigger GOTCWWnnnn - nnnn is your time type that has the difference.
This will start re-evaluation on the day 1 of work week. Here you can read the correction time type nnnn using HRS=Dnnnn. Either you do the required recalc on day 1 and reset the nnnn balance to 0 or carry it forward to the next day...so on day 2 you can read using HRS=Lnnnn and ADDDDnnnn for the current day.
The main thing is to remember is to reset the value of your correction time type to "0" when you are done with it for re-evaluation purpose. This will prevent an infinite loop. Hope this helps.

Help needed to understand an example in livedoc

Hi,
Below is what I pasted from livedoc - an example of using
events. However, since I am new to flex, I don't understand how I
use this. How can I run this example? Thanks!
package {
import flash.display.Sprite;
import flash.display.DisplayObject;
import flash.events.*;
public class KeyBoardEventExample extends Sprite {
private var bgColor:uint = 0x00CCFF;
private var size:uint = 80;
public function KeyBoardEventExample() {
var child:Sprite = new Sprite();
child.graphics.beginFill(bgColor);
child.graphics.drawRect(0, 0, size, size);
child.graphics.endFill();
addChild(child);
stage.focus = child;
child.addEventListener(KeyboardEvent.KEY_DOWN,
keyDownHandler);
child.addEventListener(KeyboardEvent.KEY_UP, keyUpHandler);
private function keyDownHandler(event:KeyboardEvent):void {
trace("keyDownHandler: " + event.keyCode);
trace("ctrlKey: " + event.ctrlKey);
trace("keyLocation: " + event.keyLocation);
trace("shiftKey: " + event.shiftKey);
trace("altKey: " + event.altKey);
private function keyUpHandler(event:KeyboardEvent):void {
trace("keyUpHandler: " + event.keyCode);
}

I wanted to know how I can use these examples to learn. The
livedoc didn't tell how to use the examples. I did understand it is
a class.
So it seems that readers have to build something that import
this class to run and see the result of the example?
