Nesting of Objects?

In structured programming languages, the code can be broken down into blocks.
The If-Then-Else statement is a block of code, and within it has nested the Test, the Then, and the Else parts of the code.
The Then and the Else parts are nested blocks which can contain more blocks of code. Objects within Objects.
Question ? Can objects be nested in this way, or an object constructed to work in this fashion?
Thank you Shadow Cat, meow

A java statement or block, which can contain many statements, does not have an intrinsic value like what you would expect with a purely functional programming language. Furthermore, java statements or blocks are not considered objects. You have to keep in mind that java syntax is derived on the heavily imperative C++ language. In your if-then-else example, the (test) portion does not contain an object at all, it must contain a boolean value, or statement that evaluates to a boolean. The (test) portion cannot contain a block of code because, as I mentioned before, code blocks do not evaluate to a value. The (then) and (else) blocks do not contain an object either, just a statement or block. This block is evaluated solely for it's side-effects. The exception to this rule is the (test) ? (then) : (else) syntax which returns a single value based on the expression in the result block.
Objects can be nested in the data-structure sense of the word. You can pass objects as parameters, get them as return values, and include them in complex data structures.

CP5 - W7 - Nested/Grouped objects - Not possible

Hi dear community,
I use Photoshop, Premiere, after effects, and many other adobe produts...
All of them have something in common, you can group or nest objects, vector based or pixel based media does not matter.
In Premiere, yoy can group a film a title and some effects into a cilp, and then use that clip as a object.
In Photoshop you can create folders under layers and use those to manage several objects at once.
But what about captivate? Even the "not to be mensioned here PowerPoint" can group objects.
Why is it so that within a company one does not reuse smart ideas and maby code?
Do not get me wrong, I love all the posibilities with captivate, but explode sometimes on the small unessesary to forget to develop things.
And to you who want to tell me about SHIFT, that is not what I am talking about
Thank you for reading!

Fill datagridview with Nested Table Object Type ???

Hello everybody, please you help me resolve my problem?
I follow this example: *(A Sample Application using Object-Relational features)* http://download-west.oracle.com/docs/cd/B14117_01/appdev.101/b10799/adobjxmp.htm
And this tutorial: *(Using Oracle User-Defined Types with .NET and Visual Studio)* http://www.oracle.com/technology/obe/hol08/dotnet/udt/udt_otn.htm
Now I have 3 Object Table: Stock, Customer and Purchase Order. With the tutorial it's OK to show the data of Stock and Customer Table [there is no nested table in], but I can't do this with table Purchase Order, the tutorial don't show how to work with Nested Table type [Missing or something ?]
When I try to display the data of table Purchase Order, I get the error:
typeName='LINEITEMLIST_NTABTYP'' is not specified or is invalid*
Follow the tutorial, I generate custom class for this UDT and get another error:
this.STOCK_REF = ((object)(Oracle.DataAccess.Types.OracleUdt.GetValue(con, pUdt, "STOCK_REF")));*
Argument Exception Unhandle: Object attribute is not mapped to a custom type member.*
Can You show me how to do this ? Show the data of the Nested Table in Visual Studio, do I have something wrong ??? Thanks and Best Regards.

I think you need to go through the tutorial more carefully. I think you are missing steps.
You are using a REF. Are you creating an object table for the objects to be stored in? Are you dereferencing the REF? This is covered by the Oracle by Example tutorial.
http://www.oracle.com/technology/obe/hol08/dotnet/udt/udt_otn.htm#t11
When you receive the nested table, it will be inside a .NET class. You can create this class by using the Create Custom Class menu item on the nested table type in server explorer.
This class will contain a ToString method and a ToXML method.
The question is, where are you attempting to display the data from this nested table? In a grid?
Does it make sense to display a nested table inside one cell of a grid? No. You would need to construct a special UI that will show the
nested table. Maybe the user clicks on the cell on the grid, which opens a new grid that displays the data. Or maybe there is a second grid on the form that always shows the nested table for the row that the first grid currently has selected.
I realize I am not providing you the code... but it sounds like you need to design a more sohisticated UI than what the tutorial is using -- one that can handle displaying one additional table per row.

How to use nested tables object in oracle form

Hello forum
How all r u ..
i need ur help guys, pls help me out...
i m using an object oriented approach to design my database by using nested tables and
varrays. it is quite done successfully.

so what is the proper way to use these type of objects to the form.
all ideas are welcomed and vry much required.

Nested Smart Objects in CS4 Win

I made a text layer and converted it to a smart object.
I copied the smart object.
When I changed the original smart object, the copy also changed. So far so good.
Then I created a second copy of the original smart object and again changed the original. The change was reflected in both the children. Still as expected.
I then combined the two offspring into another smart object. From then on, updates to the original were not replicated to the children.
By combining the children into a group instead of a smart object, changes rippled down as expected.
Is there a limit on nesting depth of smart objects to just one level? If so, where is it documented, since I have found no mention in the help file?
Otherwise, what am I doing wrong?
Thanks.
PhotoShop CS4 Win XP SP3 fully up to date.

When nesting a second time, you break the hierarchy. PS has no concept of true instancing, it merely manages hierarchies. It is utterly agnostic of what you do on the lower levels. What you do could probably be done by replacing the content of your smart objects with pre-existiing other SOed files, but depending on how many levels you plan on using, this could become pretty hairy...

Issues with click events and nested ellipse objects

I thought by now, I'd have this, but after a number of attempts, nothing is working.
Got a series of circular objects nested inside drawn using the ellipse tool in An of a sumbol called 'box' Click event in each symbol. When clicked, symbol should either hide or change CSS attributes or anything really. Tried a bunch of examples and there's four variations in my .zip file. None of them work and some are ones I've used previously. So I don't get why this isn't working and what the correct code should be. Tried getSymbol, Stage and Composition. None of them worked. So what does?

Hi, ladobeugm-
Try:
sym.$("c1").hide();
This is the same as:
sym.getSymbol("c1").getSymbolElement().hide();
sym.getStage().getComposition().getSymbol("box").$("c1").hide();
sym.getStage().getComposition().getSymbol("box").getSymbol("c1").getSymbolElement().hide() ;
Hope that helps!

Nested list object setters

I have a <nested:iterate> tag for a List of objects to provide table-like editing capabilities to their attributes (all within a <html:form> tag), which works fine. Some of those attributes are other objects though and while the getters work fine, when submitting the form the setters don't take (no errors, just doesn't set). Code looks something like this:
<nested:iterate id="idproperty" property="sampleproperty">
<nested:text name="idproperty" indexed="true" property="property1" />
<nested:nest property="property2" >
<nested:text property="nestedproperty" />
</nested:nest>
</nested:iterate>
So here property1 gets and sets fine and property2.nestedproperty gets fine, but any changes are ignored. Anyone do deep sets on properties in objects that are part of a List? Thanks.

Hi ,
I found solution be Searching SDN
Untill you do this the FM wont know which internal table is getting displayed, when it does not find anythinG , it defaults it to 1. thats why it works.
Make Sure the field catalog fieldcat-tabname = '1'.
You can see it in debugging mode.
Thanks

10.1.3.1.0 : Nested View Object sould not appear in Data Control Palette

Hello,
I have a strange behavior in JDeveloper 10.1.3.1.0.
I have two View Objects, a parent and a child, that are linked by a View Link.
Although my Application Module instanciates only the parent View Object, I can still see the child View Object in the Data Control Palette.
I've checked in JDev 10.1.3 SU5 and this behavior doesn't occur.
Is this a bug ?
Thanks,
Seb.

Hi,
I tried to reproduce but cannot. I created a m/d ViewObject that are linked by a ViewLink. I removed the detail from the master tree in the AppModule configuration so that only the master instance is left. Opening the DataControl palette, I only see the master view.
Is the project one that you upgraded from 10.1.3.0? If yes, please try and reproduce in a new workspace

Nested Remoted Objects

When using Remote Objects, I'm successfully using AMF to
transfer PHP Objects.
I have an ArrayCollection that forces the
"com.gh.vo.ContactMainViewVO" type - Works great.
My problem is when I try go another level deeper and type an
array inside of that object, it only types it as an object and not
the [ArrayElementType("com.gh.vo.ContactPhoneNumber")].
Is it possible to do this?
[Bindable]
[ArrayElementType("com.gh.vo.ContactMainViewVO")]
private var _contactsMainView:ArrayCollection;
package com.gh.vo {
import com.gh.vo.*;
import flash.net.registerClassAlias;
import mx.collections.ArrayCollection;
[RemoteClass(alias="ContactMainViewVO")]
[Bindable]
public class ContactMainViewVO {
public var contactId:int;
public var firstName:String;
public var lastName:String;
public var title:String;
public var companyName:String;
public var emailAddress:String;
[ArrayElementType("com.gh.vo.ContactPhoneNumber")]
public var phoneNumbers:Array;
package com.gh.vo {
import com.gh.vo.*;
import flash.net.registerClassAlias;
[RemoteClass(alias="ContactPhoneNumberVO")]
[Bindable]
public class ContactPhoneNumberVO {
public var contactPhoneNubmerId:int;
public var contactId:int;
public var phoneNumer:String;
public var phoneNumberType:String;
public var primaryNumber:int;

UPDATE:
I've worked around the problem by using the following (after
correcting some spelling errors *nubmer):
[ArrayElementType("com.gh.vo.ContactPhoneNumber")]
public var phoneNumbers:Array;
[ArrayElementType("com.gh.vo.ContactPhoneNumber")]
private var _phoneNumbers:ArrayCollection;
public function get phoneNumbers():ArrayCollection {
return _phoneNumbers;
public function set phoneNumbers( phoneNumbers:* ):void {
var ac:ArrayCollection = new ArrayCollection();
for each( var pNum:ContactPhoneNumberVO in phoneNumbers ) {
ac.addItem( pNum );
_phoneNumbers = ac;

DataGrid display problem (was WebService: nested return object)

I am invoking a web service which works fine.
resultFormat = "object"
the event.result = an ArrayCollection, it has two
ObjectProxys wrapping the actual objects.
I can check them in the debugger - the values are as
expected.
Person
personId:long
name:PersonName
PersonName - also wrapped in ObjectProxy
first:String
last:String
The DataGrid will corectly display the dataField="personId".
It displays dataField="name" as '[object Object]'
It displays dataField="name.first" as blank.
Am I navigating this incorrectly?
Will it not navigate complex data types?
Now do I get to the name?
Does resultFormat="object" of the WebService not work?
Must I use resultFormat="e4x"? If so, how do I navigate into
that?
(using FlexBuilder 3)

I can pare it down as far as this, which removes the
WebService from the equation:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"

<mx:Model id="testModel">

<lastName>Jones</lastName>
</name>
</root>
</mx:Model>
<mx:Script>
<![CDATA[
import mx.collections.ArrayCollection;
private function find():void {
var persons:ArrayCollection = new ArrayCollection();
persons.addItem(testModel);
grid.dataProvider = persons;
]]>
</mx:Script>
<mx:Button label="fill grid with one item"

Nested Domain Objects

Hai friends?
Am using hibernate3,
I have two classes Promotion and Grade
Class Grade {
private long gradeId;
private String gradeName;
getters/setters????.
Class Promotion {
private long promotionId;
private String promotionName;
private Grade grade;
getters/setters????.
Grade table
GRADE_ID
GRADE_NAME
Promotion Table
PROMOTION_ID
PROMOTION_NAME
GRADE_ID
Can any one suggest.. how can I map Promotion class in promotion.hbm.xml (hibernate)
Difficulty with me is that Promotion class contains Grade object ? I just need its GradeId only to promotion table..
Thanks to all

I want to nest an object behind text

Hey there
I am wanting to have the blue shape behind each of the headings. I want the text to be able to flow with the boxes, incase there are edits. How can I do this? have tried anchoring them but they don't sit under the text.
Many thanks
Mel

@Melanie – look at the position of the anchor in my example. It's not in the same paragraph with "Session 1".
And the different values for Space Before and Space After.
@Obi-wan – Using a special effect of the Effects Panel would be possible, but maybe could backfire* some day…
Or is it something else you are using?
I suppose it is after looking closely at your screenshot and the color of the hidden characters.
Could you reveal your trick? Ah. Could be:
"Soft Light"
* Using an effect like "Soft Light" is possible, but first check the Separation Preview Panel before including it into your workflow or making it a regular habit. Check the exact color for the text "Session 1" in my example. The fill color "[Black]" now wouldn't overprint anymore, because technically the text is stacked below the blue polygon. Not so in my first example with the Inline Anchor. There the text is stacked on top of the polygon!

Can we show the nested objects in Powershell?

I am adding a .NET type to Powershell session using Add-Type and then creating object of that type using New-Object. This is done as follows:
Add-Type -AssemblyName OuterObj
$a = New-Object OuterObj
Object of type OuterObj is successfully created. Now .NET type $a has a field named innerObj which is object of another .NET type innerObject. So I add "innerObject" .NET type and create an instance using New-Object.
Add-Type -AssemblyName innerObject
$b = New-Object innerObject
Object of type innerObject is also successfully created. Now I do as follows:
$a.innerObj = $b
Now when I print $a, it shows something like this:
innerObj : innerObject
Thus it does not display the contents of innerObject by default. When I go and explore, innerObj has the fields. I know Powershell does not show the nested objects by default but instead just shows their types, but is there a way I can specify that what
level of nesting of objects powershell should show by default? Is there something to specify to show 1 or 2 levels of nested objects?
Any help would be highly appreciated.

The simplest approach, if you're writing these C# classes yourself, is probably to override the class's ToString method. That way it will just display that way by default in PowerShell, without any extra effort on the scripter's part.
If that's not an option, then you can write PowerShell code to accomplish something similar. Here are examples of both:
# C# ToString version:
Add-Type -TypeDefinition @'
public class innerObject
public string Property1;
public string Property2;
public override string ToString()
return string.Format("Property1: {0}, Property2: {1}", Property1, Property2);
public class OuterObj
public innerObject innerObj;
$a = New-Object OuterObj
$b = New-Object innerObject -Property @{ Property1 = 'First Property'; Property2 = 'Second Property' }
$a.innerObj = $b
$a | Format-List
# PowerShell version using constructed property values with
# Format-List.
Add-Type -TypeDefinition @'
public class innerObject
public string Property1;
public string Property2;
public class OuterObj
public innerObject innerObj;
$a = New-Object OuterObj
$b = New-Object innerObject -Property @{ Property1 = 'First Property'; Property2 = 'Second Property' }
$a.innerObj = $b
$a | Format-List -Property @{ Label = 'innerObj'; Expression = { "Property1: $($_.innerObj.Property1), Property2: $($_.innerObj.Property2)" } }

Is there a way to detect redraw regions or at the very least when a display object is redrawn?

I have a layered window system that produces Windows 7 Aero Glass effect in Flash.
It consists of nested display objects, with overlays as so.
Root [
    GlassWindowTop [
       RenderedEffectBackground
     BackgroundForGlassWindowTop [
         GlassWindowMiddle [
           RenderedEffectBackground
        BackgroundForGlassWindowMiddle [
             GlassWindowBottom [
                RenderedEffectBackground
             BackgroundForGlassWindowBottom (e.g. the DesktopBackground)
Windows can be raised and lowered by changing their order in the hierarchy and adding new levels.
Each glass window has a designated background (containing all lower windows) . It draws to an off-screen Bitmap the region of the background that is under the window, and applies a blur filter, tint, and parallax effects to it, and then displays that as it's own background as RenderedEffectBackground.
The problem is that "RenderedEffectBackground" is a static rendering of the window background, so in order to update it in real time, I need to detect when it's background display object (e.g. BackgroudnForGlassWindowTop) or any nested display objects are rendered.
I could simply update all RenderedEffectBackgrounds from the bottom up each frame, but that would be inefficient.   Ideally, I could detect when a particular background changes (e.g. when a textfield cursor is flashing, or a MovieClip changes frames), and then only render from that object up. The rendering of course always has to take place from back to front, starting with the lowest window that has changed. If I could detect the redraw regions of the Flash Player (e.g. when a textfield cursor is flashing, or a MovieClip is playing), I could optimize this system even further by checking for layer overlaps and only rendering layers whose windows intersect the redraw regions, but obtaining that level of information would probably not be possible or logical since this this essentially needs to happen during some kind of pre render phase, which Flash may not support. Such a pre-render phase would itself be causing new redraw regions, but as long as it is processed from the bottom up, it could work.
Is there any AS3 function of the flash player that allows my code to obtain information about the display list as far as which display objects are due to be rendered, and then intercept some kind of "onRenderComplete" event for them right before rendering takes place so that I can render the higher display objects.
I originally tried to implement this as a filter, but pixel bender shaders in AS3 don't seem to allow sampling of an underlying object that would allow for blurring (i.e. the shader can access only the current point being rendered, coordinates passed to the sampling methods are ignored (this is documented behavior).
Any ideas?

The feature that shows the link you are mousing over hasn't been removed in 29. Maybe the add-on you are using to restore the add-on bar is covering it.
