Forward Declarations
hi all,
can anyone explain me abt forward declarations in PLSQL
Forward Declaration:
A forward declaration consists of a subprogram spec terminated by a semicolon.
SQL> declare
2 procedure proc1(p1 varchar2);--Forward
3 procedure proc2 is
4 begin
5 proc1('Hai');--Used here without defining
6 end;
7 procedure proc1(p1 varchar2) is[b]--defined here
8 begin
9 dbms_output.put_line(p1);
10 end;
11 begin
12 proc2;
13 end;
14 /
Hai
PL/SQL procedure successfully completed.

Forward Declaration in Class Builder
Hi All,
In the Class Builder (SE24)when i create a new Class, There is an option of Forward declaration in the Property Tab. In this, we can add Type Group Interface and Class. What is the Purpose of this forward declaration?
The F1 help does not provide any help.
Regards,
Kapil.in addition to above replies, it can be used for classes and interfaces in that case Forward declaration is equivalent to
CLASS <class_name> DEFINITION LOAD.
interface <interface_name> load
statements which are normally used in Program ( case for local classes )
use of Load from SAP docu
... LOAD
Effect
The variant with the LOAD addition loads a global class class from the Class Library. This statement was needed before Release 6.20 if you wanted to access one of the static components of class from within a program, or to declare an event handler for class before class had been loaded automatically. From Release 6.20 onwards, the LOAD addition is only needed if the compilation of an ABAP program fails because it includes recursive accesses of a globa l class. In such cases, you may be able to make the program compilable by explicitly loading the class before recursion.
Thanks,

Forward Declaration and "this" keyword
Consider this code:
class A {
private int i = 2 * this.j; // This will be calculated as 2 * 0 = 0
// private int i = 2 * j; //This code will not compile
private int j = 20;
}Why the "this" keyword is required for the j to be accessible? Though it is a forward declaration, what is the significance of "this" which gives visibility to the variable j. Please give some light to this.Though it is a forward declaration, what is the significance of "this" which gives
visibility to the variable jI don't think "this" alters the visibility of j: that is the instance variable j is in scope. However "Use of instance variables whose declarations appear textually after the use is sometimes restricted, even though these instance variables are in scope."
See "8.3.2.3 Restrictions on the use of Fields during Initialization" http://java.sun.com/docs/books/jls/third_edition/html/classes.html#287410
Using "this" you have a reference to the object being constructed with the j instance variable sill having its default value of zero.
Such instance initialisers would appear to be inherently less intelligible than using a constructor. -
Hi Experts,
Please let me know the use of forward declaration for a class. How to use that?
Thanks and Regards,
DebarshiHi,
Absolutely true matt...
you use forward declaration when you want to indicate that this component will be defined later but i am referring to this as of now.
so that it does not give any syntax/ run time error.

Can anyone kindly explain me in detail about Package forward declaration and where this is used and what's the purpose of using it.A example would be good
Thanks in advanceA subprogram declaration called a
forward declaration. It consists of the subprogram
specification in the package body .
CREATE OR REPLACE PACKAGE BODY declare_forward
IS
PROCEDURE pro(. . .); -- forward declaration
PROCEDURE pro2(. . .)
IS -- subprograms defined
BEGIN -- in alphabetical order
pro(. . .);
END;
END declare_forward; -
hi,
i have a package
CREATE OR REPLACE PACKAGE BODY pkgemp AS
FUNCTION fNeedsCpeReview(
p_order_id IN VARCHAR2 DEFAULT NULL)
RETURN product_info_tbl
is
CURSOR csr_ord_control IS
SELECT action_cd
FROM ord_control
WHERE order_id = l_order_id;
begin
select * from abc where enum=1234;
execute immediate create table abc(
enum number);
END pkgemp;
-- please forget abt the function and cursor.
-- the table 'abc' is not present in the DB
-- so we cannot execute select statement and compilation error even though we are creatign that table after 'select' statement
-- we need to do forward declarartion.
my question is how do we do a forward declaration for creating a table ?Hi,
Creating tables in procedures is rarely necessary in Oracle.
Describe what you're trying to do, and someone will suggest a good way to do it. Many people have used global temporary tables where they thought creating a table on the fly was necessary.
If you really do have to use table (abc) that may not exist at compile time, or if abc may be dropped and recreated after the procedure is compiled, then do everything that involves abc using dynamic SQL.
Remember that EXECUTE IMMEDIATE works on strings, so
execute immediate create table abc(
enum number);is incorrect, but
execute immediate 'create table abc(
enum number)';will work. -
No logical forward declared in action {0} in Web Channel
Hello
We are getting this error (No logical forward declared in action ) in CRM Web Channel when we are trying to retrieve a service order.
Any Ideas????Hello,
I would guess that this maybe due to come config in your struts-config.xml
I would check the f tansaction type that is been used and the transaction category
The only transaction category working with ICSS are:
- BUS2000116
- BUS2000120
- BUS2000112

Receiving the warning of class forward declaration
I am trying to build the Clustering Plug in project on my Leopard. I have following 2 queries -
In that project an interface class is defined as
@interface ClusteringController : NSWindowController { ....... ..... .... } @end.
And this class is used in implementation class using forward declaration as follows
@class ClusteringController;
then in one fuction it is used as follows
(long) filterImage:(NSString*) menuName {
ClusteringController *cluster = [[ClusteringController alloc] init]; [cluster showWindow:self]; return 0; }
When i try to build this project it showing a warning as follows
warning: receiver 'ClusteringController' is a forward class and corresponding @interface may not exist
Also there is 1 more warning is coming
warning: no '-updateProxyWhenReconnect' method found
This warning is coming for the following line of code
if(delegate) [delegate updateProxyWhenReconnect];
Can anybody help me to overcome these warnings?shaktirsg wrote:
And this class is used in implementation class using forward declaration as follows
@class ClusteringController;
An implementation requires an #import of the entire interface file for any class used in the code. As a rule:
Use @class when a class is used in an @interface
Use #import when a class is used in an @implementation
if(delegate) \[delegate updateProxyWhenReconnect\];
warning: no '- updateProxyWhenReconnect' method found
It looks like the compiler doesn't know the class of 'delegate'. Can we see the code that sets the 'delegate' variable? Also please let us know where updateProxyWhenReconnect is declared. Is it declared in the interface for the class to which 'delegate' belongs? If so, it might be good for us to also see that @interface file.

PLS-00323 forward declaration in PLSQL Version 10.
Hello.
I have a package which contains forward references which compiles on a 9i database.
However, when I try to compile an exact copy of the procedure on a 10g database it returns an error
"PLS-00323: subprogram or cursor 'P_PA_ACTION_START' is declared in a package specification and must be defined in the package body"
I was wondering if there were any differences in the rules concerning forward references in pl/sql 10.
Thanks in advance.

I've been following (roughly) the simple virus scanner interface that SUN provides, and adapted it into a slightly heavier weight filter that interfaces with libclamav. At first both were compiled using GCC, and I thought due to some of the weird problems I had when debugging flags were inserted, maybe Sun Studio would give better results. It hasn't, and I'm at a bit of a loss as to what to do next.
The symptom is that parts of the message just dissapear, and I see the old mime boundaries within the message body, so it seems like there's some pointer indicating where the message starts that's being corrupted by something in my code.
Interestingly, if I stop processing the message while still inside the headers, there is no problem, but that's not a very effective virus scanner if it can only look at the content type and filename of the part now is it?
This happens regardless of whether I use GCC or CC, and I'm using 0.88.1 of clamav. The output message is shown last. It should be fairly obvious what's wrong with it.
Here's my code, perhaps someone can tell me what I'm doing wrong.
** WARNING ** This IS NOT polished code, so please don't expect it to be perfect. It's clean, but includes absolute pathnames, and some other nauties that should be removed before anyone even thinks of reusing this. Once it actually works, I'll do the nessisary code cleanup, and release this to the community to do whatever anyone wants with.

Boundary_(ID_iOVR4MBjhWJn/mh7Ij+BUQ)Ok, so it's not my code. Using the virus_scanner_simple.c example from SUN, if you change the decode_inspect routine to return MTA_OK for every call (which should technically just let the message pass) it has the same behavior as my program. (Not all that suprising since mine is a derivative of said program)
That said, this now looks like a library issue. I'm using Sun Java System Messaging Server 6.2-3.04 (built Jul 15 2005) according to the SMTP prompt, and was wondering if perhaps I should apply:
http://sunsolve.sun.com/search/document.do?assetkey=1-21-118207-42-1&searchclause=6306404
The issue seems to be in the mtaDecodeMessage function, and occurs when the decode_inspect function is allowed to parse the message body, not just the message headers.
The machine is a Sun Ultra 4500 running Solaris 10. Here's the banner:
SunOS cookie 5.10 Generic_118822-23 sun4u sparc SUNW,Ultra-Enterprise
Has anyone else had similar problems using the MTA SDK? Is there anything I'm missing here (besides the above mentioned patch) that might fix this? -

DambyIf you need to call a procedure which has yet to be defined in your package, you can use forward declaration...
That means that you declare the procedure/function before the place it's going to be called (typically people do this at the top of the package) without providing a body for the code...
PACKAGE BODY ms_gen_process_email as
PROCEDURE get_email_details
p_metric_name IN VARCHAR2,
p_current_stage IN VARCHAR2,
P_ACTION in varchar2,
p_email_type_table out email_type_table

Hi all
I'm trying to build HTMLDOC as part of my larger attempt to install FOG which is a free ghost clone. I'm running into a make error 1 presumably related to the png configuration. But if it is the png conf, I'm not sure how to pinpoint what part is causing the error. Your help is kindly appreciated.

/* Special munging to support doing things the 'cygwin' way:

* PNG_BUILD_DLL -- building dll
* PNG_USE_DLL -- building an application, linking to dll
* (no define) -- building static library, or building an
* application and linking to the static lib
* 'Cygwin' defines/defaults:
* PNG_BUILD_DLL -- (ignored) building the dll
* (no define) -- (ignored) building an application, linking to the dll
* PNG_STATIC -- (ignored) building the static lib, or building an
* application that links to the static lib.
* ALL_STATIC -- (ignored) building various static libs, or building an
* application that links to the static libs.
* Thus,
* a cygwin user should define either PNG_BUILD_DLL or PNG_STATIC, and
* this bit of #ifdefs will define the 'correct' config variables based on
* that. If a cygwin user *wants* to define 'PNG_USE_DLL' that's okay, but
* unnecessary.
* Also, the precedence order is:
* ALL_STATIC (since we can't #undef something outside our namespace)
* PNG_BUILD_DLL
* PNG_STATIC
* (nothing) == PNG_USE_DLL
* CYGWIN (2002-01-20): The preceding is now obsolete. With the advent
* of auto-import in binutils, we no longer need to worry about
* __declspec(dllexport) / __declspec(dllimport) and friends. Therefore,
* we don't need to worry about PNG_STATIC or ALL_STATIC when it comes
* to __declspec() stuff. However, we DO need to worry about
* PNG_BUILD_DLL and PNG_STATIC because those change some defaults
* such as CONSOLE_IO and whether GLOBAL_ARRAYS are allowed.

Second, when you do your make, there is no reason to run it as root (until you do the make install) For the initial build, it is much safer to not use root; plus all the files in your home directory will continue to belong to use, not to root.
But, try the AUR. -
BDB vxworks 6.6 kernel port error
Hello,
I have Berkeley DB 4.7.25 compiled in kernel. When I try the example in txn_guide.c, I have got the following error:
Error opening environment: S_dosFsLib_FILE_NOT_FOUND
I'm all done.
value = 10 = 0xa
I traced the source code it fails in __rep_reset_init() when it tries to open file __db.rep.init. How can I fix this? Thanks.

How to create a Custom UIView and How to instantiate that ?
How to create a Custom UIView and How to instantiate that ?
In Flash, all we need to do is create a MovieClip and assign it a class name in the library.
Instantiation is a simple matter of:
var newclass:CustomClass = new CustomClass({initialization_data:1652});
addChild(newclass);
At this current point in time, my understanding of creating custom UIView in xcode is limited to the understanding that you have to:
1: Forward declare the class in the header.
2:
]newclass *CustomClass in @interface's {}
and THEN
@property (nonatomic, retain) newclass *CustomClass;
in the header file also.
3: Nib initialization in the implementation file in viewDidLoad and do "addSubview".
==============================
Based on my limited understanding at this point, I find the need to
@property (nonatomic, retain) newclass *CustomClass;
at the header somewhat limiting...as it denotes you must know how many instance you will create in the application before hand.
I believe I am wrong here, hence, my question is, how do I add custom UIViews with initialization codes in real time ?hi,
one workaround i could think of is using the CM views to search for content that belongs to a category and display it in a custom way.
http://www.oracle.com/technology/products/ias/portal/html/plsqldoc/pldoc904/wwsbr_api_view.html
this only allows you to search for the meta-data available in the CM views but not the content of an item that is available when doing a search.
in the next major portal release we will have a publich search API that can be used for these type of requirements. you can execute your search and format the results in the way you want.

Deep DDIC-Structure - Method to get the Comp.Type of a sub-structure
Dear colleagues,
thought the subsequent piece of coding might be helpful for the following problem:
In DDIC you have created a deep/nested Structure e.g. a complete Business Document representation like
s_doc_header type struct_doc_header
(incl.) item type tab_item
(incl) party type tab_party etc.
Now for some purpose you need to access somewhere a sub-part of this structure, e.g. the party-part. You only know (dynamically) the component name "party", but need for dynamic access also the Component Type ("tab_party") (in order to make use of a "CREATE DATA lr_reftodata TYPE (determined_comp_type)." )
The following piece of coding should help to query any start component type (here "struct_doc_header") for its embedded components.
Its a recursive use of features provided by the very nice class(set) of cl_abap_structdescr.
I implemented it as a static method.
When doing so, you need to ensure, that the TYPE-GROUP "ABAP" is linked to the class (class properties --> forward declarations),
Let me know if you find it useful.
And apologies in advance, if the same problem was already posted in the forum. I did only a rough search before due to a lag of ideas for appropriate search-strings ...
Best regards,
Rudy
