Speed of class-enhancer

Hello,
on enhancing classes (using the appropriate ant-task) I found out that
it is somewhat slow. Since the model I enhance has almost 300 classes
things will take a while.
My question: Is there a possibility to speed-up class-enhancement (other
than using a faster machine ;-)
Regards,
Andreas

My question: Is there a possibility to speed-up class-enhancement (other
than using a faster machine ;-)Unfortunately enhancement just has a lot of work to do, what with parsing
the XML metadata and parsing the class bytecode and such. One thing:
running the enhancer on a list of class names will be faster than running
it on a list of .jdo files, which in turn will be faster than running it on
a list of .class files. Other than that, though... sorry.
Don't mind, I thought about something like that. But I didn't want to
miss some hidden switch and haven't asked for it :-)
But concerning the names: Currently I apply the ant-task on jdo-files
using an embedded fileset. How to provide a list of file-names within
the task? Or does this work only for the enhancer class directly?

Andreas

Limitations of Class Enhancement

Hi Experts,
In Enhancement Framework, if we do class enhancement and add a method to our class. What will be the restrictions or limitations of the added method and the class?

Sangeeta.

Hi sangeetha,
The class doesn't create any notification by which can be detected if .

When does the SD speed rating/class come into play?

Let's say now that I've recorded a video on a class 10 chip, throw it in my computer and for whatever reason have put it on a class 2(or 4, 6, etc) chip to transfer somewhere else. Okay now at the moment where I put that video on the lower class chip did I lose any quality?
Can anyone breakdown why these speed ratings/classes are important?
Thanks for the time and help guys.

Class 10 is unnecessary for AVCHD video including 1080/50p.
Panasonic recommend using Class 4.
I believe the situation is something like that pertaining to the old Mini-DV tapes.
You could buy standard tapes or Pro tapes, the latter being far more expensive.
The inference was that the tapes were formulated differently.
In actual fact both tapes were the same!
So why the difference in name and price?
Well all tapes suffer from occasional dropouts and manufacturers test samples from their batches.
If the samples from one batch shows normal amounts of dropouts, they class that as a standard quality tape.
If the samples show less dropouts than normal, the whole batch is classed as Pro quality.
However, it's quite possible that the samples tested were not representative of the whole batch and you could end up paying Pro prices for standard quality.
I believe the situation is the same with SD card speeds.
The Class 10 are supposedly guaranteed to achieve those speeds.
The rest are just as fast but are not guaranteed.
In any case, as I said at the beginning, if you are using an AVCHD camera, Class4 is more than good enough.
Don't waste money on Class 10.

Class Enhancement without a .jdo file

Is it possible to do a byte code enhancement using the KODO APIs passing in
a data structure containing the .jdo metadata file information without
having to explicitly create a .jdo file?
I'm looking at using the enhance() method of JDOEnhancer class and it looks
like I have to have a .jdo file on disk. Is there any way to avoid it?
In my enviornment I read information from a master metadata file, use that
to generate Java code, invoke the compiler on it and now I'd like to invoke
the enhancer on the class files - i'd like to do all this one shot. Since I
have all the information needed in memory, I don't want to create a .jdo
file and have the enhancer read that file.
Thanks
Vijay

Vijay-
You do always need the .jdo metadata file for your classes; the JDO
specification requires it. Note, though, that you could just have a
single top-level package.jdo file that holds the metadata for all your
classes, so that you would only need to create a single file.
Technically, I suppose you could use a custom ClassLoader that overrides
getResourceAsStream() (since this is the way we locate .jdo metadata
files for classes), and return a textual stream of the contents of the
..jdo metadata. It might work, but we advise against it, since using
custom ClassLoaders can introduce very tricky problems that are
difficult to debug.

BSP Controller Class Enhancement - calling problem while execution

Hi all,
We are having a requirement in the EREC-Publication.
We have to insert 2 Droop-down fields on screen providing the F4 help for them.
BSP is modified to add the required fields.
Also, the Controller class methods are enhanced so that the given F4 list table is populated.
Here the issue is, when we call the BSP application a fresh and go to the required page, F4 help gets populated and the list is displayed. This means that the Enhancement is also being called. - Confirmed after inserting a break-point.
Then if i navigate to "Previous page" or "Initial page" using the link that is generated by the SAP Standard. Then when i come back to the same page again. the Enhancement for filling the F4 help list is not called and as a result the F4 help remains empty...
Is there any solution for the same i am not able to figure out what is exactly going wrong?
Thanks and Regards,
Kunjal Patel

Hi Sharmila,
The BSP Application in concern is a SAP Standard and hence, we need to enhance the same.
What you say is correct that we need to do it in the DoInit method. However, as far as possible Modification of SAP Standard code should be avoided. For the same, we have used the Implicit Enhancement point to enhance the required Method of the class.
This Enhancement is not called every time the class method is called. Hence, the worry.
Any suggestions?
Thanks and Regards,
Kunjal Patel

How to enter Enhancement Mode of ABAP OO Classes: Add Methods, Pre-Methods.

Hello,
do you know how to enter the enhancement mode of the class builder?
I want to enhance a standard global ABAP OO class by implicit enhancements for inserting methods, attributes or pre- and post-methods - as described in <a href="http://help.sap.com/saphelp_nw70/helpdata/en/58/4fb541d3d52d31e10000000a155106/content.htm">Online help</a>.
I start the SE24 on my NW 7.0, but there is no menu Edit-> Enhancement Operations-> Enhance Class/Interface as written in <a href="http://help.sap.com/saphelp_nw70/helpdata/en/86/b83142680d5c33e10000000a155106/content.htm">Online Help</a>.
When I press the Display button, there is no enhancement button (the spiral), and the sub entries of menu Edit-> Enhancement Operations, like Insert Pre-Method are inactive (gray).
In SE80 I don't find them too. The only implicit enhancements I found are on the beginning and end of methods implementation code.
Do you have experience enhancing classes?
Best regards
Michael Umlauff

Hallo Michael,
You first have to go in se80 or se24
Then menu Class-> Enhance
Then you will be able to use Edit-> Enhancement Operations-> Insert Pre-Post Methodes

Walter

Do you see the problem if you just enhance the class from the
command-line "jdoc" tool?
Also, if you just don't initialize the log, do you still see the
problem (e.g., making it a lazy initialization via some static
getLog() method)?

This seems to be a problem that happens under some classloader

Do you have a special <classloader> element for your <enhance> target?
If so, does it still occur if you remove it (conversely, does it still

How to enhance exception class based on CX_ROOT

I have created an exception class based on CX_ROOT (or CX_STATIC_CHECK, CX_DYNAMIC_CHECK). Now, I need to enhance its "constructor" method with my own parameters. How can I do this? Currently system does not allow this. But, I have seen many other exception classes enhanced the way I want? Any idea?
Any pointers will be helpful.
Regards, Neetu

Hello Neetu
Two steps are required to get additional IMPORTING parameters in the CONSTRUCTOR method of your exception class:
(1) Create exception IDs (tabstrip Texts )
Example: ID=ZCX_SDN_CLASS, text=Invalid data type for field &FIELD& on screen &SCREEN& &REPORT&
(2) Add corresponding instance attributes (read-only) to your exception class
Examples: attributes FIELD, SCREEN, REPORT
Now the CONSTRUCTOR has the additional IMPORTING parameters FIELD, SCREEN and REPORT.
If you raise your exception class using id=ZCX_SDN_CLASS then the wildcards (e.g. &FIELD& in the text) will be replaced by IMPORTING parameter FIELD.
Regards
Uwe

Eight-Class Model QoS for voice and video

One of the QoS recomendation in the SRND "Enterprise QoS" is to create a Eight-Class QoS Model utilizing a seperate priority queue for voice and video.
It says that even though you have only one physical priority queue, that LLQ has an implicit policer that allows for time-division multiplexing of the single priority queue. This implicit policer abstract the fact that there is essentially a single LLQ within the algorithm and, thus, allows for the "provisioning" of multiple LLQs.
My question is if anyone has tried this and if there are any limitations on the platforms that can support this "dual-LLQ design."

Design guide which is basically the QoSDesign recommendation bible.
http://www.cisco.com/univercd/cc/td/doc/solution/esm/qossrnd.pdf
It has a large section for WAN recommendations...while you may not
need to follow one of these Based on my understanding what what you
have for a link (DS3) and what you are trying to accomplish, I
believe the following section would be a good place to start.
- WAN Aggregator QoS Design
- WAN Edge Classification and Provisioning Models
- High Link Speed QoS Class Model
- Eight-Class Model

Syntax error when creating Overwrite method - implicit enhancement

Hi,
I am working at a customer site, and need to implicitly enhance certain methods. I would like to create an Overwrite Method for the following class/method:
CL_CRM_MKTDEF_DEFAULTS_PERSIST -> HEADER_WITH_KEY_EXITS_IN_DBASE( )
I proceeded in the following way:
Open class CL_CRM_MKTDEF_DEFAULTS_PERSIST in class builder (SE24)
Select menu path Class -> Enhance
Create, or select, enhancement implementation ZCRM_MKTDEF_PRD
Select method HEADER_WITH_KEY_EXITS_IN_DBASE, select menu path Edit -> Enhancement Operation -> Add Overwrite Method
Click on u201CNavigation to Overwrite Exitu201D
After navigating to the Overwrite Exit, I click on "Check" to perform a syntax check (notice, I have not yet implemented any code. Everything so far has been done by the wizard).
Now, I get the following error:
Enhancement Implementation ZCRM_MKTDEF_PRD
Unable to interpret "IS_DEFAULTS_ATTR". Possible causes: Incorrect
spelling or grammar.
When I create Overwrite methods for any other method in the same class, the same error does NOT occur. As far as I can tell, there is nothing special about this method that should cause this error.
I would greately appreciate any help that any of you could give me on this one.
thank you and best regards,

How to use Enhancement Framework in ECC 5.0 and 6.0

hi
is there any good tutorials on enhancement framework? i have gone through the help but its not very clear. if anyone has stepby step guide will be useful.
~Suresh

This is an old question... but i think it is very useful for the developers if anyone search it and find my answer relevant like it with immediate effect.....
What is Enhancement Framework?????????
Enhancement Framework is the new paradigm to bring all enhancement techniques under one roof. It can also be switched using Switch Framework. The following are different enhancement technologies available under this framework.
• Source Code Enhancement
• Function Group Enhancement
• Class Enhancement
• Kernel-BADI Enhancement
Semantically related enhancement options are grouped under a ‘Simple Enhancement Spot’. ‘Composite Enhancement Spot’ contains one or more of Simple and other Composite Enhancement Spots. On the other hand (implementation side), various related implementation elements are grouped under a ‘Simple Enhancement Implementation’. A ‘Composite Enhancement Implementation’ can contain one or more of Simple and other Complex Enhancement Implementations.
1.Source Code enhancement
Whenever enhancement needs to be incorporated directly into the ABAP source code, this technology shall be provided. Implementing this technology is also called as Source Code Plug-In. There are two types of Source Code enhancements possible.
• Implicit enhancement option
• Explicit enhancement option
>>>Implicit enhancement option
Throughout the ABAP system, enhancement options are automatically available at certain pre-defined places. Some of the implicit options are:
• At the end of all the programs (Includes, Reports, Function pool, Module pool, etc.), after the last statement
• At the beginning and end of all FORM subroutines
• At the end of all Function Modules
• At the end of all visibility areas (public, protected and private) of local class
******Note that, in order to implement any of these Source code enhancements, you need to be in the ‘Change Enhancement mode’ (the spiral icon available in the editor). Technically the source code plug-in implementations are stored in a separate include program and not as part of the original source program.***********
>>>>Explicit enhancement option
The Implicit enhancement options are provided at specific source code places explicitly by SAP (Note that these enhancement definitions can also be created by partners and customers in their code).
There are two types of Explicit Enhancement options available. One which can be provided at a specific place - called Enhancement Point, and another which can be used to replace a set of statements – called Enhancement Section. For this, we now have two new ABAP statements, viz.
• ENHANCEMENT-POINT
• ENHANCEMENT-SECTION
When the Enhancement-Section is implemented, only the implementation gets executed and the original code doesn’t get executed. This is a new technique, which didn’t exist previously in any of the old ways of enhancing, to exclude any standard SAP code from execution. Because of this, there can be only one active implementation of an Enhancement-Section. On the other hand, there can be multiple active implementations of an Enhancement-Point, in which case all the implementations will be executed with no guarantee in the order of execution.
we mainly use above framework .......if nybody need further and more information let me knw...

Proper way to use data throughout a class?

I know global variables aren't a thing in c#, as that goes against the rules.
So I have a couple of functions and subroutines (pardon my vocabulary if it isn't canon). I use a simple array to transfer data back and forth. Is this the proper way to do this? As in most efficient, readable, and expandable?
class Program
static void Main()
bool[] MotorPosition = new bool[4];
MotorPosition[0] = true;
MotorPosition[1] = false;
MotorPosition[2] = true;
MotorPosition[3] = false;
while (true)
MotorPosition = UpdateMotorPosition(MotorPosition);
DisplayMotorPosition(MotorPosition);
System.Threading.Thread.Sleep(64);
static bool[] UpdateMotorPosition(bool[] MotorPosition)
bool[] NewMotorPosition = new bool[4];
for (int x = 0; x < 4; x = x + 1)
NewMotorPosition[x] = !MotorPosition[x];
return NewMotorPosition;

Absolutely amazing! I learn something new every day. I wonder when programming will cease to amaze me.
using your example jdweng, I was able to add a counter to your code and move the motor position to the test class; as well as add another motor by instancing the class again!
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace ConsoleApplication1
class Program
static int Main(string[] args)
Test test = new Test();
test.Initialize(); //Assigns initial value to MotorPosition
Test test2 = new Test();
test2.Initialize(); //Assigns initial value to MotorPosition
while (true)
if (test.MotorUpdateCount == 40) Console.ReadLine(); //pauses at 40 to make it easy to see output upto that point
if (test.MotorUpdateCount > 1000) return -1; //ends program
test.MotorPosition = test.UpdateMotorPosition(test.MotorPosition); //updates motor 1 position
test.DisplayMotorPosition(test.MotorPosition); //displays motor 1 position
if (test.MotorUpdateCount > 20) //at count 20, engages motor 2
test2.MotorPosition = test2.UpdateMotorPosition(test2.MotorPosition); //updates motor 2 position
test2.DisplayMotorPosition(test2.MotorPosition); //displays motor 2 position
System.Threading.Thread.Sleep(128); //slows the loop down to reasonable speed
public class Test
public int MotorUpdateCount = 0;
public bool[] MotorPosition = new bool[4];
public void Initialize()
MotorPosition[0] = true;
MotorPosition[1] = false;
MotorPosition[2] = true;
MotorPosition[3] = false;
public bool[] UpdateMotorPosition(bool[] MotorPosition)
bool[] NewMotorPosition = new bool[4];
for (int x = 0; x < 4; x = x + 1)
NewMotorPosition[x] = !MotorPosition[x];
MotorUpdateCount = MotorUpdateCount + 1;
return NewMotorPosition;
public void DisplayMotorPosition(bool[] MotorPosition)
string CombinedDisplay = null;
for (int x = 0; x < 4; x = x + 1)
CombinedDisplay = CombinedDisplay + MotorPosition[x].ToString();
Console.WriteLine(CombinedDisplay);
Console.WriteLine(MotorUpdateCount.ToString());

Implementing a MousePressListener as a separate class

I've got a MousePressListener inner class (i.e. MouseListener that listens for MousePressed event) within a MouseApplet class. I want to implement this inner class as a class of its own. I suspect that I'm going to need to store a reference to the MouseApplet object in the Listener class and also include a constructor in this Listener that sets the reference to the MouseApplet class.
The logic's coming, but can't think of the syntax. Any ideas?
Thanks.

don't bother - just make your MouseApplet implement MouseListener
it saves you coding, memory, speed and class file size.
