Need information on string encoding

Between NSStrings.h and CFStringEncodingExt.h there are scads of encodings listed but I haven't been able to find any detailed information on them. Does anyone know where I can get such information?
A secondary question: is there a simple way of including 8-bit ASCII into a string in my code? For instance, if I want to say NSString *x; x = @"ß=√π"; how can I do it?

What sort of information do you want? That isn't a small topic.
Unless you need to read any of those wacky string encodings (such as if you were writing a web browser with compatibility with web sites from 1993) you don't need to worry about any of them except for UTF-8. UTF-8 will handle 95% of your needs. MacOS X resource files and Java text uses UTF-16 for another 4.8% of your needs.
A secondary question: is there a simple way of including 8-bit ASCII into a string in my code? For instance, if I want to say NSString *x; x = @"ß=√π"; how can I do it?
You put that string into a resource file (which is encoding using UTF-16) and then load it using NSLocalizedStringFromTable.
You cannot use 8-bit data in a source file. This is a limitation of the GCC compiler and has nothing to do with a Mac.

Need information about interfaces and namespaces in actionscript 3.0

Hi,
I need information about actionscript interfaces and
namespaces, I'm preparing for ACE for Flash CS3 and I need to learn
about this subjects and I can not find resources or simple examples
that make these subjects understandable.
Anybody can help me!
Thanks a lot.

Interfaces (cont.)
Perhaps the most useful feature of interfaces is that you not
only can define the data type but also method signature of the
class that implements this interface. In other words, interface can
define and enforce what methods class MUST implement. This is very
useful when classes are branching in packages and team of
developers works on a large application among others.
The general syntax for an Interface with method signatures is
written the following way:
package{
public interface InterfaceName {
// here we specify the methods that will heave to be
implemented
function method1 (var1:dataType,
var2:datType,…):returnType;
function method2 (var1:dataType,
var2:datType,…):returnType;
To the previous example:
package{
public interface IQualified {
function method1 ():void;
function method2 ():int;
Let’s write a class that implements it.
If I just write:
package{
public class ClassOne extends DisplayObject implements
IQualified {
public function ClassOne(){}
I will get a compilation error that states that I did not
implement required by the interface methods.
Now let’s implement only one method:
package{
public class ClassOne extends DisplayObject implements
IQualified {
private function method1():void{
return;
public function ClassOne(){}
I will get the error again because I implemented only one out
of two required methods.
Now let’s implement all of them:
package{
public class ClassOne extends DisplayObject implements
IQualified {
private function method1():void{
return;
private function method2():int{
return 4;
public function ClassOne(){}
Now everything works OK.
Now let’s screw with return datatypes. I attempt to
return String instead of void in method1 in ClassOne:
private function method1():String{
return “blah”;
I am getting an error again – Interface requires that
the method1 returns void.
Now let’s attempt to pass something into the method1:
private function method1(obj:MovieClip):void{
return;
Oops! An error again. Interface specified that the function
doesn’t accept any parameters.
Now rewrite the interface:
package{
public interface IQualified {
function method1 (obj:MovieClip):void;
function method2 ():int;
Now compiler stops complaining.
But, if we revert the class back to:
private function method1():void{
return;
compiler starts complaining again because we don’t pass
any parameters into the function.
The point is that interface is sort of a set of rules. In a
simple language, if it is stated:
public class ClassOne implements IQualified
it says: “I, class ClassOne, pledge to abide by all the
rules that IQualified has established and I will not function
correctly if I fail to do so in any way. (IMPORTANT) I can do more,
of course, but NOT LESS.”
Of course the class that implements an interface can have
more that number of methods the corresponding interface requires
– but never less.
MORE means that in addition to any number of functions it can
implement as many interfaces as it is desired.
For instance, I have three interfaces:
package{
public interface InterfaceOne {
function method1 ():void;
function method2 ():int;
package{
public interface InterfaceTwo {
function method3 ():void;
package{
public interface InterfaceThree{
function method4 ():void;
If our class promises to implement all three interface it
must have all four classes in it’s signature:
package{
public class ClassOne extends DisplayObject implements
InterfaceOne, InterfaceTwi, InterfaceThree{
private function method1():void{return;}
private function method2():int{return 4;}
private function method3():void{return;}
private function method4():void{return;}
public function ClassOne(){}
Hope it helps.

Determine String encoding

Hello folks,
I have a problem with converting data to UTF-8.
My task involves a Oracle database table with a long field.
First of all, the data in this table can be Chinese/Japanese/English/Korean encoded.
So when I retrieve the data, I will need to invoke:
String localStr = new String(rs.getBytes(CONTENT_INDEX),"SJIS");
String utf8Str = new String (localStr.getBytes("SJIS"), "UTF8");
where rs is java.sql.ResultSet
Then I will need to store the utf8 String to a new database table.
Since the default encoding is "ISO8859_1" and that I have no idea whether the data is
Chinese/Japanese/English/Korean encoded, how can I make the proper conversion?
Since the data is in Long Field and I will have to use getBytes() to get the data and
convert it to the local encoding.
So I am asking if there is any way that I can determine what these bytes'
original encoding was?
Is there anything in Character class that I can make use of??
Pls help.

Thank your for your replies.
My problem is that I have no idea whether the row of data I am getting is either Big5/SJIS/KSC5601/ISO8859_1 encoded, everything stores in one table while no column is used for indicating the encoding used.
My client needs to upgrade their content management system which only able to interpret UTF8 data. So the old data needs to convert to UTF8 and store in a new table.
E.g. SJIS (Japanese) to UTF8 to SJIS (again when shown on browser)
Now the problem is that how to find out that these bytes are SJIS encoded originally???

JPA string encoding

How can I tune the String encoding in JPA ?
In some cases I need UTF8 encoding, in some cases I need UTF16.
What annotation/attributes do we assign values to ?
How do we do this? Thanks.

String encoding in the database.
Why - because it is the right thing to do: I have decided that.still not clear, what does that have to do with JPA? that's something you would configure in your database, using database specific tools. the java layer doesn't really care how the database stores the strings.

I need Information about Grid

Hello,
The first, i don't speak english very well.... ;)
the company for which work has 3 seats now, but is going to open 5 more.
All these seats are small, and the cost to install Oracle in each one of them is very elevated.
i would like to know to me if Grid Computing can help me centralizing everything in a Seat. The scalability is something very important. and i need have several instances of BD oracle up...
I need information...
Yo can write me to [email protected]
Thanks in advance

Hi.
By seat, I assume you mean site or location.
It's difficult to answer this type of question as it depends on so many factors. Personally, I would always go for the centralized solution. This way you don't need to worry about replication or distribution of data. Those things are always a nightmare.
RAC is great for high availability, and it will allow you to increase your horsepower as and when you need it, but you still need to consider your performance erquierments up front.
Of course, centralization comes with it's own set of problems. Are you going to connect to the central server via the web, VPN, leased line? What happens when the connection is unavailable?
There is just so much to consider...
Cheers
Tim...

The last 12 months' worth can be obtained via your on-line MyVerizon account; look under View Bill and use the drop-down to select the appropriate bill. Anything prior to the past 12 months would need to be obtained via Customer Service; there is a charge (I believe $5 per copy, but I'm not sure).
