Best way to order dependent objects

I have a Group object which has a List of Monitor objects. A monitor object
has a name. I'd like the monitor objects to be ordered by name. What is
the simplest way to do this? I can't use the setOrdering method because I'm
not using a query when I call the Group's getMonitors() method. I looked at
the ordered extension but I don't understand it. I tried it like this:
<class name="MonitorGroup"
identity-type="datastore"
> 
<field name="monitors"
> 
<collection
element-type="Monitor"
> 
</collection>
<extension vendor-name="kodo"
key="ordered"
value="true">
</extension>
</field>
</class>
But I still get this warning when I run my application:
WARN MetaData - The field "monitors" in class "MonitorGroup" implements the
java.util.List type, but does not specify an "ordered" metadata extension.
This means that the order of this list will not be maintained. In a future
release of Kodo JDO, fields of List types will be ordered by default.
BTW are Lists ordered in 2.5 or is this scheduled for 3.0?
Thanks,
Michael

Patrick,
In the past I suggested to add Collection Comparator support to JDO.
And I believe you planned to discuss it on JDO spec panel. Did it go
anywhere?
I also use TreeSet and comparable in most cases (just be careful to fully
initialize and never change all collection member fields which are used in
compareTo() or you will have wrong sort order). I would prefer comparators
to implementing comparable because comparable is "global thing" (you want
your comparable interface implementation to be universal and useful outside
of owning collection) while for your collection sorting can be and often is
owner specific

Best way to do a Object which holds a collection of another object type.

Best way to do a Object which holds a collection of another object type. The best place for data in a database is.. no real surprise.. in tables. If that data is temporary of nature, global temporary tables cater for that.
Storing/caching data using PL/SQL requires very expensive private process memory (PGA) from the server. This does not scale.
I'm writing a caching object to store another object. Irrespective of how l33t your haxor skillz are, you will not be able to code as a sophisticated, performant and scalable PL/SQL data cache, as what already exists (as the database buffer cache) in Oracle.
The cache is only valid for a session, so I want a store the data in a nested table.Not sure how you take one (session local data) to mean the other (oh, let's use a nested table).
Session local data can be done using PL/SQL static variables. Can be done using name-value pairs residing in a context (Oracle namespace). Can be done using a global temporary table.
The choice is dependent on the requirements that need to be addressed. However, the term +"caching+" has very specific connotations that say that a global temporary table is likely the best suited candidate.

Best way to make a object details page

I have a dataTable, built with a sessionBean List. We have to make a link "show detail" in each row, and redirect to a new jsp showing selected row object details.
Whats the best way to retrive the object selected?
a commandLink with param (haschcode value) and search in list isn`t possible because is a sessionBean..
I have some ideas but not with JSF....
thanks

1) Bind h:dataTable to an UIData property in main backing bean.
2) Add a h:commandButton or h:commandLink to a column and bind it with an action method in main backing bean.
3) In the main backing bean action method simply retrieve the row object byRowObject selectedRowObject = (RowObject) uiDataProperty.getRowData();and navigate to some display details page.
4) In the display details page just access the data by #{mainManagedBean.selectedRowObject.someProperty} and so on.

Best way to populate an object

This is more of a coding convention question. I was wondering what is the best or industry standard way to populate an object.
If there's a method that returns an object is it better to pass an empty object (just declared) into the method, have the method populate the object and then just use the object
e.g. Object foo;
populateObject(foo);
foo.getProperty();
or
have the method return a newly populated object
e.g. Object foo = populateObject();
foo.getProperty();
thanks

It's better to pass in an object as an argument when performance is important. You can pass in the same object instead of creating new objects for each call to getProperty().
It's better to return a newly populated object when the caller does not know what class of object will be returned. The getProperty() method could return a subclass of Object.
As is often the case, the answer is: it depends.

Best way to MouseDrag multiple objects around a scene.

So I am having a little trouble trying to drag 3 Box's in a scene.
Originally I had it set up where each was relocated to an x,y translated Z and set to a HWD. Then I figured I would, instead of the mouse click on the box itself, be in the root. From there I would look through all of the root.getChildren() then made that see if it contained the x,y position.
Then from knowing which of my root Children I clicked I did root.getChildren.get(current).setOnDragged to figure out which one was dragged.
The code itself worked except for finding which box I was on.
The issue I find is that I onyl have getX, getSceneX, and getScreenX. X, and SceneX produce the same value, and ScreenX is useless. I tried then to do event.getX() - root.getLayoutX() to make the contains function to work, but it wasn't working and would require me to change up more things. getLayoutX() was = 0 since I didn't set the root location, only the locations of the box's.
From there I kept wondering if there was a better way. Then I thought maybe to loop through every element in my root or in an arrayList(Which is what I used, but realized the root.getchildren should work like the original) but the problem is it keeps only registering the last one in the list, so it just loops and that's it.
So what I want to know is, what would be the best way to figure out what object I'm in?
Originally I use the contains(Swing) but Swing is different, and now especially since we can register mouseEvents to each node, shouldn't we know exactly which one we are on, just by looping through each of them? I figure that's easier than having to check every single mouse position contained within, especially if I have 10000 things to check?

I slightly modified your code for 3D.
- added a pointlight
- added a phong material
- the rectangle changed to a box
- the circle changed to a sphere
- add scene.setCamera(new PerspectiveCamera(false));

Best way to restore "deleted objects" container's ACLs?

Hi,
I haven noticed, when using the the LDP for reading the security description of "Deleted Objects" container that LDP returns to me "Error: Security: No Such Attribute <16>". Should it be readable or not? At least all other environments
I can read it.
And if it should be readable, then what is the best way to fix it? Take the ownership, and etc... If I take the ownership, then I assume some ACLs are reseted and installations like Exchange and Lync requires domain preparations, right?

AFAIK, deleted objects lose their ACL.

A handy class to know about but not really what I'm after.

Connection connection = Tools.setUpConnectionToDB(url,userName,pwd, this);

Best way to order dust jacket by itself (without book)?

I just received my first hardcopy book that I ordered through Aperture. Just my luck, I discovered a typo in my text on the dust jacket, which I missed the 3 times I proofread it on-screen.
I didn't see a way of ordering the dust jacket by itself. I suppose I could print to PDF and get it printed locally somewhere, but there doesn't seem to be a way of specifying pages to print (e.g. the first two pages and last two pages).
Otherwise I'll use white-out?

I don't understand your issue. Where do you need code in wdDoModifyView() to configure a LinkToAction? Just create an action with a text/icon, assign it to the "onAction" event and the LinkToAction is complete.
The usage of context elements for data binding has for example the advantage that you can use the same context element for controlling properties of different UI elements. Using context mapping you can also control UI elements in different views.
In the given use-case you could for example compose your screen from different views and control the enabled/visibility state with one commen supply function which would be implemented in the component controller or some custom controller. If you would use wdDoModifyView() and direct access to UI elements you had to write code inside each view controller.

Best way to determine what objects has been selected in a Collection?

Hi all
I´m currently developing an application where a user can create a PDF based on the choices made from multiple collections.
Each collection contatins 10-50 items, and there are about 8 different collections with objects.
Checkboxes are used to select items from these collections.
I´m wondering how I would best determine what choices have been made, and if would be good to remove all objects from
a collection that has NOT been chosen?
Currently, it looks like this (exemple for one collection, but same solution is used for all collections)
private Collection<Texture> textureList = new ArrayList<Texture>();
private ArrayList<Texture> textureResult = new ArrayList<Texture>();
          for (Texture t : textureList) {
               if (t.isSelected()) {
                    textureResult.add(t);
          }After this iteration, textureResult is used to create the PDF.
This PDF contains lists with dynamic frames, so I need to now how many
items was selected before creating the PDF.
Wondering if this is the best/most efficient way to do this though?
Maybe it doesn´t matter all that much with lists this small, but I´m still curios :-)
I guess you could do something like this aswell
          while (textureList.iterator().hasNext()) {
               Texture t = (Texture) textureList.iterator().next();
               if (!t.isSelected()) {
                    textureList.iterator().remove();
          }Any suggetions?

Or do you know how to do that and you're asking how to keep track of those selected items in the Collection?
I don't do GUIs, so I can't help with the first two, but for the third, you could create a new collection holding just the selected ones, or remove the unselected ones from the original Collection.
and if would be good to remove all objects from
a collection that has NOT been chosen?That's entirely up to you. If you create the original Collection when the user makes his selection, and only need it to survive one round of selection, that may be fine. But if you need to get back to the original collection later, and it's expensive to create, then you might want to just create a second collection and add items from the original to it if they're selected.

Best way to creat an OBJECT in OM

Hi All,
As i know there are multiple options available to create Objects for OM,
Now what is the best possible way to create number of Objects in OM Out of the following.
PPOCE
PPOC_OLD,
PP01,
PO03,PO10,PO13
Please guide.

You need to understand 3 core things to have good understanding of OM..
1) Objects
2) Relationships
3) Attributes
Each element of your org. structure is an Object. It is related with another object and it has certain attributes..
Org. Unit, Position and Person are different examples of objects each of which has its own attributes.. when you link them together it forms your org. strcture..
To depict very basic structure, you can use "Simple Maintenance" option.
You can use "Expert Mode" to define attributes of the objects..
And to do both activities at one place, you can do so through "Org. & Staffing" interface..
So organizational and Staffing interface is in detailed and coprehensive you may use it for better understandings.
The following are the detail transaction you may use .

Best way to import all objects into work repository located on a new master respository

Hi,
We have two separate master repositories, one for all development work repositories (Development, ST, UAT, IAT), and one for Production.
What would be the best approach to export and import all objects from the Dev Repository into the Prod Work Repository located on the Prod Master Repository.
Internal Ids of all work repositories are different.
We have tried putting everything into a solution and exporting that, but that did not work when we tried to import it.
We successfully exported and imported a single scenario, however this is not very practical as we have over 500 scenarios.
All suggestions welcome,
Thanks,
Nic

Thanks,
But we want to keep Dev Work Repositories separate to Prod Work Repositories on their respective Master Repositories.
So our end result will have:
1) All Development Work Repositories located in the Development Master Repository on the Development server.
2) The Production Work Repository located on the Production Master Repository on the Production Server.
3) The ability to update a Solution or similar in Development with all changes to any objects.
4) The ability to import the Solution into the Prod Work Repo on the Prod Master Repo and execute via a load plan.
Is this possible?

Best way to add new objects to a Group?

I have been trying to figure out how to keep things organized in the timeline. Which is very important when you get very complicated. If I pick a group and then an obj and hit the group tool, it makes a new group instead of just having it added to the original. The only work around I have found is to ungroup the first group and then everything is nested in the new group. That is a pain.......I would love to just select an object with my middle mouse, just drag it into a group in the timeline. Or is there an easier way?

OpenCL: best way to resize memory objects

I'm a beginner in OpenCL and I have a question about memory management (like 99.99% of noob questions about OpenCL, I guess...). I enqueue the kernel for execution inside a loop in the host code; at each iteration the size of the buffers used for memory objects passed as kernel arguments is different. Currently, I do something like this using the C++ wrapper API (which BTW I find much more easy to use than the C interface, that nevertheless seems to be the most used interface yet):
// Set platform, kernel, queue etc.
for (int i = 0; i < nIterations; i++){
// Set buffer sizes and fill them
// OpenCL section
cl::Buffer clBuffer1 = cl::Buffer(context, CL_MEM_READ_ONLY | CL_MEM_USE_HOST_PTR, bufferSize1*typeSize1, (void *) &(buffer1[0]));
cl::Buffer clBuffer2 = cl::Buffer(context, CL_MEM_USE_HOST_PTR, bufferSize2*typeSize2, (void *) &(buffer2[0]));
cl::Buffer clBuffer3 = cl::Buffer(context, CL_MEM_WRITE_ONLY | CL_MEM_USE_HOST_PTR, bufferSize3*typeSize3, (void *) &(buffer3[0]));
kernel.setArg(0, clBuffer1);
kernel.setArg(0, clBuffer2);
kernel.setArg(0, clBuffer3);
queue.enqueueNDRangeKernel(kernel, cl::NullRange, cl::NDRange(someValueForRange), cl::NullRange);
queue.enqueueMapBuffer(clBuffer2, CL_FALSE, CL_MAP_READ, 0, bufferSize2*typeSize2);
queue.enqueueMapBuffer(clBuffer3, CL_TRUE, CL_MAP_READ, 0, bufferSize3*typeSize3);
// Do something with retrieved data
I'm sure there are thousands of less-than-sub optimal memory access patterns in the code above, but for the moment I'm facing this issue: is there a way to modify the size of the cl::Buffer objects without having to reinstantiate them at each iteration of the loop? I fear that this constinuous create/destroy of cl::Buffer objects causes a full reallocation of memory on the CL device at each loop iteration, potentially degrading the overall performance. I think that also a size modification (a' la STL, to be more clear) could result in some memory reallocation, but hopefully less frequently. Or is it better to statically define oversized buffers outside the loop and play with the size arguments of enqueueMapBuffer inside the loop to transfer only the needed range of data to the GPU at each iteration of the loop?
Sorry for the possibly confusing question but as I said I'm a noob with OpenCL and this particular kind of problem seems to be not very common. Thanks.

Hi
First a vector drawing will not work on the web unless you convert it too svg, (only supported on 40% of browsers IE requires a plug-in) or use it within flash. You will have to convert it to gif / jpeg / png. If you convert to png this will retain the transparency for you.
As to the size, then resizing should be done in illustrator or similar then exported into photoshop or fireworks, and from these use your export for web option, and optimize the image.
