Selector and Arrays...

Example:
We have a PublicObject, which has an attribute call members, this attribute is a publicobjectarray.
Now we want to search for all publicobjects, that have a special person included in the members-attribute.
How is it possible to realize that with a selector?

This cannot be done using Selectors. You will
need to use the search API (oracle.ifs.beans.Search) to do this.
Selectors will work in cases where search
involves one table (in most cases that translates to one iFS class) only. Because
of the way array type attributes are represented in iFS, you will need to use search api.

All the xml and arrays are getting NULL Problem

Hello guys
I am working on a project which uses xml loading, e4x and array manipulation extensively, and it was going good but now I got stuck on a strange problem. Whole code was fine and application was working and responding in a desired way, but then mystourisly it stopped working and started to retun NULL values to almost all the actionscript (internal) Arrays and XML varibales.
Now Whenever i load xml file and assign the loaded values to internal xml variables, internal values get only NULL instead of data.
Same is the situation with Arrays, I created some components in mxml, and when i passed them to arrays by reference, code gets compiled successfully, but again Array has only null values [that code was working fine too]

Loops and Arrays help

Hi,
I'm a freshman in college and new to java. I am completely lost and really need help with a current assignment. Here are the instructions given by my teacher...
Building on provided code:
Loops and Arrays
Tracking Sales
Files Main.java and Sales.java contain a Java application that prompts for and reads in the sales for each of 5 salespeople in a company. Files Main.java and Sales.java can be found here http://www.ecst.csuchico.edu/~amk/foo/csci111/labs/lab6N/Main.java
and here http://www.ecst.csuchico.edu/~amk/foo/csci111/labs/lab6N/Sales.java It then prints out the id and amount of sales for each salesperson and the total sales. Study the code, then compile and run the program to see how it works. Now modify the program as follows:
1. (1 pts) Compute and print the average sale. (You can compute this directly from the total; no new loop is necessary.)
2. (2 pts) Find and print the maximum sale. Print both the id of the salesperson with the max sale and the amount of the sale, e.g., "Salesperson 3 had the highest sale with $4500." Note that you don't necessarily need another loop for this; you can get it in the same loop where the values are read and the sum is computed.
3. (2 pts) Do the same for the minimum sale.
4. (6 pts) After the list, sum, average, max and min have been printed, ask the user to enter a value. Then print the id of each salesperson who exceeded that amount, and the amount of their sales. Also print the total number of salespeople whose sales exceeded the value entered.
5. (2 pts) The salespeople are objecting to having an id of 0-no one wants that designation. Modify your program so that the ids run from 1-5 instead of 0-4. Do not modify the array-just make the information for salesperson 1 reside in array location 0, and so on.
6. (8 pts) Instead of always reading in 5 sales amounts, allow the user to provide the number of sales people and then create an array that is just the right size. The program can then proceed as before. You should do this two ways:
1. at the beginning ask the user (via a prompt) for the number of sales people and then create the new array
2. you should also allow the user to input this as a program argument (which indicates a new Constructor and hence changes to both Main and Sales). You may want to see some notes.
7. (4 pts) Create javadocs and an object model for the lab
You should organize your code so that it is easily readable and provides appropriate methods for appropriate tasks. Generally, variables should have local (method) scope if not needed by multiple methods. If many methods need a variable, it should be an Instance Variable so you do not have to pass it around to methods.
You must create the working application and a web page to provide the applications information (i.e., a page with links to the source code, the javadoc and an object model) to get full credit. You can use the example.html's from the last two labs to help you remember how to do this.
I'm not asking for someone to do this assignment for me...I'm just hoping there is someone out there patient and kind enough to maybe give me a step by step of what to do or how to get started, because I am completely lost from the beginning of #1 in the instructions.
Any help would be much appreciated! Thank you!

First ask the person who gave this asignment as to why do you require two classes for this , you can have only the Sales.java class with main method in it . Anyways.
Let Main.java have a main method which instanciates a public class Sales and calls a method named say readVal() in Sales class.
In the readVal method of sales class define two arrays i.e ids and sales. Start prompting the user for inputting the id and sales and with user inputting values keep storing it in the respective arrays .. Limit this reading to just 5 i.e only 5 salesPerson.
Once both the arrays are populated, call another method of Sales class which will be used for all computations and output passing both the arrays.
In this new method say Compute() , read values from array and keep calculating total,average and whatever you want by adding steps in just this loop. You can do this in readval method too after reading the values but lets keep the calculation part seperate from input.
You must create the working application and a web page to provide the applications information (i.e., a page with links to the source code, the javadoc and an object model) to get full credit. You can use the example.html's from the last two labs to help you remember how to do this. I think this is ur personal stuff , but if you want to use web page , you probably will require to use servlet to read values from the html form passed to the server.

How Both View Selector and Column Selector in one report dashboard section

Can we use a view selector and column selector inside a report in one section of the dashboard?
env: obiee 10g
Appreciate any links and pointers
Thanks in Advance
Kris

hi kris,
Can we use a view selector and column selector inside a report in one section of the dashboard?Here view selector is nothing but having multiple views and selecting depends on what end user want to see.You are saying in a single report in once section only.
If it is a single report you can go with using a column selector.
Note:-View selector and column selector combination can be used.....but it looks wierd as you need to select view at the same time the corresponding column.
UPDATED POST
Yes you can have it by creating different compound layouts with pivots in it.
Cheers,

Capturing the row selector and perform logical delete

Hi All ,
I add a tabular report in one of my page .But in the MULTI_ROW_DELETE button I like to capture the checkbox (row selector) and fire a PL/SQL anonymous block where rather than performing actual row delete it will update a database field and perform some sort of logical delete .
Now my problem is I cant able to capture that what are the rows need to be logically deleted :
DECLARE
vRow BINARY_INTEGER;
BEGIN
FOR i IN 1 .. apex_application.g_f01.COUNT
LOOP
vRow := apex_application.g_f01(i);
update test123 set delete_flag='y' where col2=vRow ;
end loop;
end;
Its throwing error .Can anyone help on this pls how to write the pl/sql code to perform the logical delete.
Thanks in advance ,
Regards,
Debashis.

Guys ,
Got the solution by searhcing several of the therads from Denes...
Create the checkbox from Form page :
htmldb_item.checkbox(1,t.USERNAME) DeleteItem,
and then captured it as :
FOR i in 1..HTMLDB_APPLICATION.G_F01.count
LOOP
UPDATE table1 set DELETE_FLAG='Y'
WHERE USERNAME = HTMLDB_APPLICATION.G_F01(i);
END LOOP;
Cheers,

OBI Column selector and Condition step

In OBI 11.1.1.6.2 I have an analysis which contains a column selector, a pivot table and a regular table. The pivot table uses the fields of the column selector.
In this configuration it is not possible to add a condition step to the regular table. Only when removing the column selector view it is possible to add a condition step.
I know that it is possible to create a dashboard that uses two analysis: one pivot table with the column selector and one regular table with the condition step. But this is not what I want.
I am not sure if this is a works as designed thing, or that it is a bug. If it's works as designed, than I would have expected a message that it is not allowed to add a condition step when a column selector is present.
Does anybody have experience with this?
Thanks,
Bas

Hi there !
Thanks for your help but I managed to get it working. For references purposes, I`ll post it here.
My problem now is this :-
How can I issue another SQL statement and store the results in the same array?
Pls note . One Sql per table so, that`s the issue ?
Can someone help with a followup code ?

// for every record instance aRow
aRow = new String[numColumns];
// store in aRow the values of the record
for(int i=0;i<numColumns;i++)
aRow[i] = rset.getString(i+1);
//When aRow is full store it in the vector
allRows.addElement(aRow);
// when the rset finished print all the Vector

is there ay posibilities to show view selector ad column selector in a single row?
Please help on this..its going nearly a week..

NXT Flatten to String Not Working with Clusters and Arrays

Hello,
My name is Joshua and I am from the FIRST Tech Challenge Team 4318, Green Machine. We are trying to write a program that will write to a configuration file and read it back. The idea is that we will be able to write to a config file from our computer that will be read by our autonomous program when it runs. This will define what the autonomous program does.
The easiest way to do this seems to be flattening a data structure to a string, saving it to a file, and then reading back and unflattening it. The issue is that the flatten to string and unflatten from string VIs don't seem to work with arrays and clusters on the NXT. It does work when running on the computer. We've tried arrays, clusters, clusters in arrays and arrays in clusters, none seem to work. Thinking it was something to do with reading the string from a file, we tried bypassing the file functionality, still not working. It does work with basic data types though, such as strings and numbers.
No error is thrown from what we can tell. All you get is a blank data structure out of the unflatten VI.
The program attached is a test program I've been working on to get this functionality to work. It will display the hex content of what is going into the file, coming out of the file, and then the resulting data from the unflatten string, as well as any errors that have been thrown. The data type we are using simulates what we would like to store. There is also a file length in and out counter. The out file is a little larger because the NXT write file VI adds a new line character on to the end (thus the use of the strip white space VI). This character was corrupting even basic data types saved to file.
I would like to know if there is a problem with what we are doing, or if it is simply not possible to flatten arrays on the NXT. Please ask if you have any questions about the code. Thank you in advanced!
Joshua

Hi jfireball,
This is a very interesting situation. Take a look at what kbbersch said. I also urge you to post in the FTC Forums. You posted your question to the general LabVIEW forums, but by posting to the FTC Forums, you will have access to others that are using the NXT hardware.

Strange behaviour of "And array Elements"

If u connect an empty boolean array to "And Array Elements" function, The output is "True" !. Is this correct?. Is there something wrong ?. Please Help.

Hi J.A.C
This is correct.This is an explanation I've found: "This behavior is intentiional, and stems from elementary Boolean logic. The Boolean algebra primitives are analogous to numeric operations are integers. Just as the identity element for addition is 0, and for multiplication, 1; the identity for Boolean OR is FALSE, and for AND, TRUE. For example, x^0 == 1; that is, x times itself zero times is by definition 1. For the same reason boolean x ANDed with itself zero times is TRUE."
If this is not acceptable for your application, then just use the "Array Size" VI first to check if you've an empty Array (Array size=0) and then you can pass or not the array to the "And Array Elements" function.
Hope this helps.

Performance of System.arraycopy and Arrays.fill

I have some code where I call a function about 1,000,000 times. That function has to allocate a small array (around 15 elements). It would be much cheaper if the client could just allocate the array one single time outside of the function.
Unfortunately, the function requires the array to have all of its elements set to null. With C++, I would be able to memset the contents of the array to null. In Java, the only methods I have available to me are System.arraycopy() and Arrays.fill().
Apparently, Arrays.fill() is just a brain-dead loop. It costs more for Arrays.fill() to set the elements to null than it does to allocate a new array. (I'm ignoring possible garbage collection overhead).
System.arraycopy is a native call (that apparently uses memcpy). Even with the JNI overhead, System.arraycopy runs faster than Arrays.fill(). Unfortunately, it's still slower to call System.arraycopy() than it is to just allocate a new array.
So, the crux of the problem is that the heap allocations are too slow, and the existing means for bulk setting the elements of an array are even slower. Why doesn't the virtual machine have explicit support for both System.arraycopy() and Arrays.fill() so that they are performed with ultra-efficient memsets and memcpys and sans the method call and JNI overhead? I.E. something along the lines of two new JVM instructions - aarraycpy/aarrayset (and all of their primitive brethern).
God bless,

A newly allocated array begins its life with null in its elements. There is no need to fill it with null.
As Michael already stated, I'm not redundantly resetting all of the elements to null. Here's some code that demonstrates my point. You'll have to replace my PerfTimer with your own high performance timer. (i.e. sun.misc.Perf or whatever) Also note that the reason I'm only allocating half the array size in allocTest is to more accurately model my problem. The size of the array I need to allocate is variable. If I allocate the array outside of the function, I'll have to allocate it at a maximum. If I allocate inside the function, I can allocate it at exactly the right size.import java.util.*;
public class AllocTest {
private static final int count = 100000;
public static void main( String[] args ) {
    for ( int i = 0; i < 10; ++i ) {
      allocTest();
    double allocStartTime = PerfTimer.time();
    allocTest();
    double allocTime = PerfTimer.time() - allocStartTime;
    for ( int i = 0; i < 10; ++i ) {
      copyTest();
    double copyStartTime = PerfTimer.time();
    copyTest();
    double copyTime = PerfTimer.time() - copyStartTime;
    for ( int i = 0; i < 10; ++i ) {
      fillTest();
    double fillStartTime = PerfTimer.time();
    fillTest();
    double fillTime = PerfTimer.time() - fillStartTime;
    System.out.println( "AllocTime (ms): " + allocTime / PerfTimer.freq() * 1000 );
    System.out.println( "CopyTime (ms): " + copyTime / PerfTimer.freq() * 1000 );
    System.out.println( "FillTime (ms): " + fillTime / PerfTimer.freq() * 1000 );
private static void allocTest() {
    for ( int i = 0; i < count; ++i ) {
      Object[] objects = new Object[ 8 ];
private static void copyTest() {
    Object[] objects = new Object[ 15 ];
    Object[] emptyArray = new Object[ 15 ];
    for ( int i = 0; i < count; ++i ) {
      System.arraycopy( emptyArray, 0, objects, 0, emptyArray.length );
private static void fillTest() {
    Object[] objects = new Object[ 15 ];
    for ( int i = 0; i < count; ++i ) {
      Arrays.fill( objects, null );
}I getH:\>java -cp . AllocTest
AllocTime (ms): 9.749283777686829
CopyTime (ms): 13.276827082771694
FillTime (ms): 16.581995756443906So, to restate my point, all of these times are too slow just to perform a reset of all of the elements of an array. Since AllocTime actually represents dynamic heap allocation its number is good for what it does, but it's far too slow for simply resetting the elements of the array.
CopyTime is far too slow for what it does. It should be much faster, because it should essentially resolve to an inline memmove. The reason it is so slow is because there is a lot of call overhead to get to the function that does the actual copy, and that function ends up not being an optimized memmove. Even so, one on one, System.arraycopy() still beats heap allocation. (Not reflected directly in the times above, but if you rerun the test with equal array sizes, CopyTime will be lower than AllocTime).
FillTime is unbelievably slow, because it is a simple Java loop. FillTime should be the fastest, because it is the simplest operation and should resolve to an inline memset. Fills should run in single-digit nanosecond times.

Append variable and array items after a record array search

I would like to update a variable and array item after a record array search, and wanted to know what would be the best way of carrying it out in Javascript.
In this case, if a match is found between the variable and area item, then the postcode item should be appended to the variable.
The same needs to be done for the array items, but I reckon that a for loop would work best in this scenario, as each individual item would need to be accessed somehow.
Btw due to the nature of my program, there will always be a match. Furthermore, I need to be able to distinguish between the singleAddress and multipleAddresses variables.
Hopefully this code explains things better:
// before search
var singleAddress = "Mount Farm";
var multipleAddresses = ["Elfield Park", "Far Bletchley", "Medbourne", "Brickfields"];
// this is the record which the search needs to be run against
plot = [{
postcode: "MK1",
area: "Denbigh, Mount Farm",
postcode: "MK2",
area: "Brickfields, Central Bletchley, Fenny Stratford, Water Eaton"
postcode: "MK3",
area: "Church Green, Far Bletchley, Old Bletchley, West Bletchley",
postcode: "MK4",
area: "Emerson Valley, Furzton, Kingsmead, Shenley Brook End, Snelshall West, Tattenhoe, Tattenhoe Park, Westcroft, Whaddon, Woodhill",
postcode: "MK5",
area: "Crownhill, Elfield Park, Grange Farm, Oakhill, Knowlhill, Loughton, Medbourne, Shenley Brook End, Shenley Church End, Shenley Lodge, Shenley Wood",
// after search is run then:
// var singleAddress = "Mount Farm, MK1"
// var multipleAddresses = ["Elfield Park, MK5", "Far Bletchley, MK3", "Medbourne, MK5", "Brickfields, MK2"]

3d3d3d is for red but you have a blackish and color2 is for green but you have it white the rest should be the default colors. it uses the same colors only it changes the vairiant of the color you choice there or normally moc uses colors such as green blue and such which will call your console colors for those respective fields I know moc has /user/share/moc/themes/ that you can edit or make your own for instance copy one and edit it. I think htop uses the same color count which is 8 but with so green will be white when you use urxvt. 8 for normal colors 16 for bright dark and urxvt is 256 which is 16 but can use any of the 256 colors for 16.
just to clarify you have commented out your colors 4-15 and your green and red is weird, and htop aswell as moc is 8 bit. moc theme_yellow_red is default for background so it will use urxvts background
Haahaha, that is simple. And it works!!!

Loops and arrays

Hi
I'm trying to write a loop that does the following :-
Takes an array of index values that applies to a string adds one to the value of the index and then returns the character in this position.
There are only four types of character within the string so I have tried to solve it with the following code:-

I'm trying it this way but it does'nt seem to work - I've only succeeded in confusing myself - any tips would be much appreciated

Sorry, I should have explained it better.
The situation I've got is something like this:-
I've got a string that looks something like this
'aactgctcct'
next - I've got four different arrays, each corresponding to the index of each character a, c, t and g
so they look something like this
indexa = {0,1}
indexc = {2,5,7,8}
indext = {3,6,9}
indexg = {4}
I am presently stuck at the next part - for which I have to return the character that is to the immediate right of the index value in the string that was analysed initially.
e.g. for indexa ;
0 = a
1 = c
for indexc;
2 = t
5 = t
7 = c
8 = t
etc
I don't know if this makes my predicament any clearer - I'm a genetics student this java is very new to me - I'm kinda muddling through but this bit has got me stumped !!!
