What does enum constant do?

Hi
I have a program that I need to understand. There are enum constants at many places and I do not know what they do. When I find all instances it shows me many with other different named enum constants. Like enum "Read Queue" and "Initialize" are two enums and both are of the same instances. Can someone tell me what exactly an Enum is.
Thanks

Enum is an "enumerated" datatype.
You have values of 0, 1, 2, .... But those values are meaningless. (Is "read queue" value #1? Intialize value 0?) So meaningful names are given to each of the values. So if you want to initialize, you just have to pick that item in the enum rather than remembering an arcane number.
A constant is a specific value. Note: when working with enums, it is HIGHLY recommended that they be typedef's so that if you ever need to add an item to an enum, that all instances of the constans get that new item added to it automatically.
I would recommend looking at the online LabVIEW tutorials

What does "Illegal Constant Pool Type" error signify ?

Hello,
I have developed an application on a windows system that connects to a database, places values onto an object, and displays on a screen. When I run on a windows environment everything works fine. When I export to my external server, which is linux system, I get an "Illegal Constant Pool Type" error.
What does this mean and how can I rectify?
The error message can be found at:
http://www.blazingvibes.com/blazinvibes/indexhome.jsp
Thank you all for your help.

No idea since I can't see the error or code.
And I don't know about anyone else but I don't click on links unless I know the source, so its current location isn't going to help in that matter.
Presumably you are doing printStackTrace() so the location of the error is obvious.

My Iphone 4s is plugged in charging after it has fully died. Instead of the apple appearing and staying constant on the screen...the apple is blinking. What does this mean and how do I get the phone to charge/turn back on.

- Try:
iOS: Not responding or does not turn on
- Next try letting the battery fully drain. After charging for a least an hour try again
- Last, make an appointment at the Genius Bar of an Apple store, it appears you have a hardware problem.

Any possible workaround to use annotations that require an enum constant...

I am doing code generation and following the generation gap pattern (http://www.research.ibm.com/designpatterns/pubs/gg.html). For JPA i add a few annotation like @Table or @Inheritance to the generated-once client class and not the always-generated base class. However the problem is that if the values of those annotations change, it doesnt get reflected in the generated-once code, since its only generated once - the 1st time and never touched again.
So was trying in some way to get the annotations be on the base class thats always generated and did whats mentioned in this newsgroup post http://www.eclipse.org/newsportal/article.php?id=79805&group=eclipse.platform#79805
However it doesnt work since java doesnt like non enum constants in the annotation.
I wonder if there is some approach people have come across to address this kind of problem? (apart from say generating an orm.xml always to put annotations in there)

Thats what I am generating. One class is getting split into two. One always generated, while the other generated once.
You are still missing the point of the pattern.
The pattern is
<Class that is NOT generated> becomes <generated class> <manual class>
And as I already said the fact that you have another generated class doesn't mean that you can't apply the pattern to second class.
Consider this UML diagram where A --> B means A extends B
4 Files get generated
1] ABase extends B (always generated)
2] A extends ABase (generated-once)
3] BBase (always generated)
4] B extends BBase (generated once)
It is 2 and 4 that will get the annotations for JPA - @Entity, @Table and @Inheritance.
1 and 3 will get @MappedSuperclass.
So my problem above that I mention applies to the Child (A or B) and not Parent (ABase or BBase)
The seperation into functional units are joined by inheritance.
Java doesnt have partial class methodology.
So inheritance joins the 2 functional units.That entire explanation doesn't matter. Actually the pattern doesn't matter either.
Code generation, all code generation is simple.
You take 'source', run it through a 'tool' and the output is 'code'.
For that to work you MUST have 'source' and a 'tool' that produces the 'code' that you want. If one of those pieces is missing you can't use code generation.
The variations on that are infinite. The only limitation is complexity and that at some point you reach a point of diminishing returns where it costs more to do the code generation (including maintainance) than it does to do it manually.
So your options are
1. Find some way to generate it all.
2. Find some way to seperate some of the code out so some can be generated and the other is manual (and this is sort of the point of the pattern.)
3. Do it manually.
There is no magic. I would also like to suggest that you forget about the pattern entirely. It is clever but it is more of a intro to code generation and you appear to be limiting the possibilities by that pattern and you do not need to do that.

What does the open file dialog do 'under the hood' and is there a way to simulate it

What does the open file dialog do 'under the hood' and is there a way to simulate it?
I have a bug in my code (that I've posted about before, here) which I can't fix at the moment, but I do have a workaround.
Briefly, the bug:
I call a dll from a function node, to initialise and run a spectrometer. If I start up the PC, LabVIEW and run my vi the code runs without complaint, the first call to the dll to initialise the spectrometer doesn;t return an error but the spectrometer is not detected either.
I've tried various solutions, see the link above, and none work
The workaround:
If, at any time before running the code containing the function node I open an 'open file' dialog window, select the dll and click ok/hit enter then everything is fine. When I run the main code the spectrometer is detected.
I use an express vi to open the file dialog, I specify the start path and file name as constant inputs and just click ok/hit return when the dialog pops up. I don't do anything with the dialog outputs. In fact the vi that contains the open file dialog can be run before the project containing the bug is even open.
I have to do this everytime I turn the PC on.
So, either
1) Can somewone suggest a fix for the original bug?
2) What is the easiest way to simulate the enter keypress when the open file dialog pops up
or
3) Can someone tell me what the open file dialog does under the hood that somehow causes the dll to work and can it be simulated in straight LabVIEW
I suspect that the dll itself is dodgy ( I have in the past talked to the supplier but not got very far, and I will try again but I would like a quick, temporary solution too). I'm guessing that the file dialog is making some kind of check on the file, and possibly registering its presence with the OS (winXP). I tried using the file/folder exists vi to see if checking the file like that worked but no luck.
Any help greatly appreciated.

Hi David
I am very conscious about thread hijacking but this sounded like my issue so I hope you dont mind me asking about your issue. I am hoping that you have a spectrometer from the same vendor as me and its not just me seeing an Error 1097 issue. My spectrometer is from a company called Stellarnet.
So far I have unable to get it to work with other VIs. There is one condition where I can get it to work but its no good for me.
Case 1
I open the VI in a fresh labview environment with no other VIs in memory. The code runs with no issue.
Case 2
Labview is not opened. I double click the spectrometer VI in windows explorer. The VI opens but it fails to run resulting in Error 1097. Personally, I dont see the difference between this and Case 1 above and yet it fails.
Case 3
If I already have other VI's in memory and try to load the spectrometer VI and run it fails with Error 1097. This case is the one that most important to me. I have a test executive that will load test VIs dynamically and I can't get this to work. Same problem Error 1097.
I wanted to share what I have seen with you and to let you know that maybe somebody else has the same issue. I am convinced its the DLL but the vendor dis-agreed saying it was LabVIEW. I couldn't convince him otherwise.
Thanks in advance
David

What does the "S" mean in reference to lenses? EF-S vs EF lens?

I have both a digital camera, the 60D, and recently acquired an EOS 1N 35mm film camera. I have bought lenses for my 60D but not the 1N film camera....was told that my 18-55mm lens for my 60D would not be interchangeable with the 1N? So, EF-S vs EF lens, what is the S and what does it indicate? What does the "S" mean in reference to lenses? EF-S vs EF lens?
Thanks.....I am just getting started in photography and do not know all the different terms....
James

In the simlpest of terms think of the S as standing for SMALL sensor. The sensor in crop bodies is much smaller in physical size than the area your film camera needs covering with when the shutter opens. An EF S lens won't allow light to cover the full area in the film or FF body. This allows smaller & cheaper lenses but at the expense of limiting their use.

What does $ sign in a class name signifies

I have downloaded a project as a jar file(zip), when I unzipped it it gave me two files
SchoolQadBase.java( Which has Class defn and methods)
SchoolQadBase$RecordType.java(this has a Record type defined it).
What does the $ sign in the class name signifies?
Can I just include the RecordType in my SchoolQadBase.java and delete the other file?
If I rebuilt the project does that affect any of my functionality.
SchoolQadBase$RecordType.java
public enum RecordType
CUSTOMER, END_USER, SHIP_TO, SALES_ORDER;
private String value;
public String getValue()
    return this.value;
My Java class SchoolQadBase.java
package org.atcc.erpproxy.model;
import java.io.Serializable;
import java.util.Date;
public class ErpQADBase extends AbstractErpObject
implements Serializable
   private String rollNumber = "";
   private String department1 = "";
private String department2 = "";
private String room = "";
   private RecordType recordType;
public RecordType getRecordType() {
    return this.recordType;
public void setRecordType(RecordType recordType) {
    this.recordType = recordType;
}

What does the $ sign in the class name signifies?It signifies that it is an inner class
Can I just include the RecordType in my SchoolQadBase.java and delete the other file?Definitely not

NSURLErrorDomain error -1012. What does this mean?

I'm trying to make a call to an OData resource using the OData iOS SDK and every call gives me this error code:
The operation couldn’t be completed. (NSURLErrorDomain error -1012.)
What does NSURLErrorDomain error -1012 mean?
Thanks!

Most of these kinds of things are in the documentation - from the Foundation Constants Reference:
`Returned when an asynchronous request for authentication is cancelled by the user.
This is typically incurred by clicking a “Cancel” button in a username/password dialog, rather than the user making an attempt to authenticate.`

How to avaoid java.lang.IllegalArgumentException: No enum const class

The exception will be raised by valueOf, which (quite correctly) throws it if the String you pass to it doesn't match any of the enum constants.

Don't avoid it, process it. What do you want your code to do if the string doesn't match any of your enum constants? Whatever it is, stick it in a catch clause.

What does it mean (and how do I fix) my light is solid amber?

I plugged my Time Capsule in, but the light stays amber - what does this mean and how can I fix it?

Normally on start up, the Time Capsule should flash green for a second, then display solid amber for 15-20 seconds and then...if the settings are correct....the light will turn to green. If there is a problem at this point,the amber light will normally blink slowly.
If the light stays solid amber, this indicates that the Time Capsule has "locked up" and may have possibly experienced an internal component failure.
Power down the Time Capsule for at least 15 minutes
Hold in the reset button and keep holding the reset button in for another 10 seconds as you plug the power back in to the Time Capsule
Release the reset button and see if Time Capsule will go through the normal start up sequence
If you get a slow blinking amber light after approximately 30 seconds, you can now reconfigure the Time Capsule again using AirPort Utility
If you try the factory default reset sequence above a few times and the light remains constant amber, I'm afraid that you'll need to take the Time Capsule to an Apple store to let them have a look.

What does compiler error " import test; `.`expected" mean ?

Hi,
I have a compiler error for following lines. There is a file called Const.java and this file is located on the same directory with the file I intend to compile. However, it seems compiler looks for an import package...
What does "import test;" command mean ? What is missing in following source code ?
c:\test> javac -classpath ./ -d ./ *.java one/*.java
Error :
test2.java:1: '.' expected
import test;
^
Source :
(c:\test\test.java)
class test
     public static void main(String[] args)
          System.out.println("Hello World!");
(c:\test\one\test2.java)
package one;
import test;
class test2
     public static void main(String[] args)
          System.out.println("Hello World!");

Source :
(c:\test\test.java)
class test
     public static void main(String[] args)
          System.out.println("Hello World!");
Since you have no package statement in here, then it is said to reside in the default package. This means, (I believe) that you will not need to use an import statement to use this class. However, if I am wrong, which you can find out in testing, another solution would be to include all you classes in the same package, in this class have both source files start with the line :
package one;Hope this helped.

LV 8.5.X: Enum Constant, Number of Elements

Hello,
I want to determine the number of elements of an enum constant, is
that possible at all?
Thanks and greetings,

What is the thing behind indexing 2?

That is buried inside the LabVIEW data-type definition:
Enumerated 8-Bit Integer
In the following example of an enumerated 8-bit integer for the items am, fm, and fm stereo, each group of characters represents a 16-bit word. The space enclosed in quotation marks (" ") represents an ASCII space.
0016 0015 0003 02a m02 fm 09f m" " st er eo
0016 indicates 22 bytes total. 0015 indicates an enumerated 8-bit integer. 0003 indicates there are three items.
Here's the VI I was talking about.

Where 1 =1, Where 1 = 2, what does it mean?

Could anyone roughly tell me what does it mean?

Yes, create table t1 as select * from t where 1=2 will create a copy of t with no data in it. IT would take about as long to do it that was as it would to do it explicitly as:
CREATE TABLE t1 (col1 NUMBER, col2 VARCHAR2(10));copying the column list from t. The size of the table used in the select is not material because Oracle is smart enough to know that 1=2 will not return any rows from the selected table so will not even try.
Any equality condition of constants will work the same as 1 = 1 e.g. 'fred' = 'fred' or 1999545678342 = 1999545678342. Similarly, any inequlity predicate will work the same as 1=2 e.g. 'fred = 'barney' or 1999545678342 = 66

What is a constant selection?

What is a constant selection?

Hi,
In the Query Designer, selections are used to determine the data to be displayed at query runtime.
Navigation and filters are used to alter/ change these selections.
The Constant selection function marks this selection as a Constant in the Query Designer.
This constant selection is not affected by the navigation and filter.
In short, the selection does not/ cannot be changed.
It remains a Constant
Hope this helps...

What does ACL mean in Verify Permissions?

I have been having problems since upgrading from Panther to Leopard on December 12 of 08. I think I have the majority of them addressed... I am running the disk utility and verifying and repairing permissions 2 times per month, emptying caches almost every day, and zapping the PRAM in order to address constant freeze-ups on startup... sometimes at the blue screen and sometimes the wheel just keeps turning, turning, turning, etc., but it still happens daily. Any ideas why on this one?
Now I am getting this message when verifying permissions:
ACL found, but not expected on "Applications/Utilities"
ACL found, but not expected on "Applications"
ACL found, but not expected on "Library"
What does ACL mean and why is it not expected?
Any answers? It would be appreciated.

Hi! Most have found that if they download the new combo update and reapply the update the acl messages in repair permissions disappear and the report will be clean for the first time. Tom
