Comparing objects for equality with UDT's

Hi.
I was wondering how Oracle does comparison for equality of objects that contains parameters of user defined types.
Suppose I have an object with a parameters whose types are:
1) number,
2) varchar2,
3) nested table type,
4) associative array
and I want to compare two such objects for equality. Would Oracle compare all parameters of this 2 compared objects field-by-field (and dig recursive to "leafs"), or would it compare only 1), 2) and doas nothing with 3) and 4)?
Must I declare an order method for such comparison?

You didn't specify a version - this is correct for 10.2, I'm not sure if it has changed in 11g.
By default it will compare for exact equality - i.e that every attribute is the same. You can also only do it in SQL, not PL/SQL. Also can only do = and <> - you cannot do < or > etc.
You need to create a MAP or ORDER method on the type to do any more sophisticated comparison (Same as in most object oriented languages). Documentation is here http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14260/adobjbas.htm#sthref211

Comparing layers for equality

Is it possible to compare two different layers to see if they are in fact the same image?
I'm actually working on a game at the moment. The game map was created by using game sprites created by other people. For example, I found 5 different pictures of trees, and copy pasted them into photoshop multiple times to create a forest. I have 100 trees in my photoshop document, but in reality, they are all made up of only 5 images. I want to save out each of these trees into a format usable by my game engine. I want to save each layer as an image, but avoid saving duplicates. Thus the need to compare layers for equality.
Is it possible to do this within a photoshop script? Thanks for any help you can provide.

but wouldn't this only work in the instance of them being on top of each other?
That bit of code presumes:
The layers are in the same document
The layers are the only two layers visible
The content of the layers is aligned.
The layers have simple content (no layer masks, vector masks, layer styles)
There may be other assumptions that I'm making, but this is all that I can think of.
For the trees/forest problem, I would iterate though the tree-layers.
Create a new document that is as large as the largest tree-layer in the forest.
Hide the background layer.
Copy the first layer to the new document.
Copy the second layer to the new doc
Do the layer comparison code from above my previous post
If the layers are the same, delete the new one.
Go to the next layer in the forest document.
Copy and compare the new layer against each layer in the new document.
Delete it if it's a dupe.
When you're done, the new document should have only the unique trees.

Comparing dates for equality using API

Hello,
I was wondering if you could help me understand if it is possible for me to compare two dates for equality.
I am looking to only compare the date and the month. So, if I am checking "today" with another objects Date for equality, it obviously fails because the compareTo and the equals method of both Date and Calendar, I think, are comparing even the timestamps.
here is something I wrote for testing, which obviously is of no use
Calendar today = Calendar.getInstance();
Calendar later = Calendar.getInstance();
later.set(Calendar.HOUR, 03);
System.out.println(today.getTime());
System.out.println(later.getTime());
if(today.equals(later)){
   System.out.println("BIG BANG");
if(today.compareTo(later)<0)
   System.out.println("Today Date is Lesser than my Date");
else if(today.compareTo(later)>0)
   System.out.println("Today Date is Greater than my date");
else
   System.out.println("Both Dates are equal");
Date today = new Date();
Date myDate = new Date();
myDate.setHours(23);
System.out.println(today);
System.out.println(myDate);
if(today.compareTo(myDate)<0)
   System.out.println("Today Date is Lesser than my Date");
else if(today.compareTo(myDate)>0)
   System.out.println("Today Date is Greater than my date");
else
   System.out.println("Both Dates are equal");
   So is then the only way left, is using the simple date formatter and going about things ?

How to convert an array collection instance to a complex object for interaction with webservice

Hi there,
I have a stubborn problem that I am trying to work out the best way to solve the problem. I am interacting with a WebService via HTTPService calling a method called find(String name) and this returns me a List of ComplexObjects that contain general string and int params and also lists of other Complex Objects. Now using the code:
ArrayCollection newOriginalResultsArray = new ArrayCollection(event.result as Array)
flex converts my complex objects results to an arraycollection so that I can use it in datagrids etc. Now up until this part is all good. My problem is when getting a single instance from the results list, updating it by moving data around in a new datagrid for example - I want to interact with the webservice again to do an create/update. This is where I am having problems - because these webservice methods require the complex object as a parameter - I am struggling to understand how I can convert the array collection instance back to my complex object without iterating over it and casting it back (maybe this is the only way - but I am hoping not).
I am hoping that there is a simple solution that I am missing and that there is some smart cookie out there that could provide me with an answer - or at least somewhere to start looking. I guess if I have no other alternative - maybe I need to get the people who built the service to change it to accept an array - and let them do the conversion.
Any help would be greatly appreciated.

Hi Bert,
According to my knowledge you can use describeType(Object) method which will return an XML... That XML will contain Properties and values just iterate through the XML and create a new Object..   Probably u can use this method...
public function getObject(reqObj:Object,obj:Object,instanceName:String,name:String=null,index:int=-1):Obj ect
            if(!reqObj)
                reqObj = new Object();
            var classInfo:XML = describeType(obj);
            var className:String = instanceName;
            if(name!=null)
                className=name+"."+className;
            if(index!=-1)
                className=className+"["+index+"]";
            for each (var v:XML in classInfo..accessor)
                var attributeName:String=v.@name;
                var value:* = obj[attributeName]
                var type:String = v.@type;
                if(!value)
                    reqObj[className+"."+attributeName] = value;
                else if(type == "mx.collections::ArrayCollection")
                    for(var i:int=0;i<value.length;i++)
                        var temp:Object=value.getItemAt(i);
                        getReqObject(reqObj,temp,attributeName,className,i);
                else if(type == "String" || type == "Number" || type == "int" || type == "Boolean")
                    reqObj[ className+"."+attributeName] = value;
                else if (type == "Object")
                    for (var p:String in value)
                        reqObj[ className+"."+attributeName+"."+p] = value[p];
                else
                    getReqObject(reqObj,value,attributeName,className);
            return reqObj;

How to convert a mesh to an object for use with pathfinder?

(I tried searching for this problem, but all that came up were a lot of posts about crash reports.)
My problem is that I've taken over a document where a lot of objects have mesh fills. I need to take these objects and convert them to black and white, and they need to be compound paths (ie have holes in them where there used to be color). But whenever I choose two objects, where one has a mesh fill, I can't use the pathfinder. I also can't expand the object with the mesh.
I've tried looking in the help files and search the web, but not found anything so far. Does anyone have the solution?
Why doesn't the pathfinder simply discard the mesh in the first place if it can't work with it? I could always undo if it's not the result I expected.

I am not sure I understand any of this bu you can in CS 5 give the mesh point colors an opacity of 0% since transparency is now supported in gradient mesh.
Or if you need a shaped whole in the gradient mesh then you can simply make a non clipped non inverted opacity mask.
Here you have a combination of the opacity set to zero for one of the mesh points and a shape used as an opacity mask.

Duplicate objects for gallery

I have tried a couple of times to duplicate objects, in
different ways, so I can later put image into the objects. The
problem is that it works in Flash but when i try it out in my
browser or my friends browser it wount work at all.
So if there is one out there that can explain this or can
point me into right directions it would be alot of help.
Kind Regards

Hi Michael,
Not really, as Coherence only compares keys for equality, not the values, when deciding where to store the objects.
What you could do however, is something along the lines of what I described in the previous post -- you could introduce an intermediary pointer/reference object that would only contain an id of your true value object:
public class MyObjectReference implements Serializable {
private static final NamedCache myObjectCache = CacheFactory.getCache("myObjectCache");
private Object id;
public MyObjectReference(Object id) {
this.id = id;
public Object getId() {
return id;
public MyObject getValue() {
return myObjectCache.get(id);
Then your code would become similar to this:
NamedCache myRefCache = CacheFactory.getCache("myReferenceCache");
NamedCache myObjectCache = CacheFactory.getCache("myObjectCache");
MyObject myObj = ...
myObjectCache.put(myObjId, myObj);
myRefCache.put(1, new MyObjectReference(myObjId));
myRefCache.put(2, new MyObjectReference(myObjId));
myRefCache.put(3, new MyObjectReference(myObjId));
Assuming your object is much bigger than its key/identifier, this approach could save you a lot of space in the cluster, as each reference object is very small, while still allowing you to access your value object using different keys and dereferencing:
MyObject myObj = ((MyObjectReference) myRefCache.get(1)).getValue();
You could replace key 1 with 2 or 3 above and the result would be the same.

Can't activate the COMPARE function for object DNL_CUST_TVAST for Adapter

Hello
I've applier OSS note 866824 to enable the exchange of the sales area flag deletion. I had to do the initial download for the customizing object DNL_CUST_TVAST but it failed because the no intial load was permitted as the data distribution was active. So I've applied note 887696 to enable the intial load for this object : I've deleted the COMPARE function for this object with transaction R3AC3. I've done the initial load for this object and now I can't add the COMPARE function : the error message is enter linked bdoc type for synchronisation load. and I don't know what to do...
if somebody can help me...
thanks a lot

Thanks for your tip but it does not work, I need to fill this field.
I just have an answer from SAP support, this value COMPARE is relevant for loading data in CDB.
there no sense to add the compare value for this object : the compare load can never be used for this object. It was a delivery error

I need help with comparing Objects of an ArrayList

Hi,
I am trying to compare a certain variable of objects which are stored in an arrayList.
for example i have a class called AuctionBid(String bidderID, BitSet itemSet, int bidValue)
and i have another class called AuctionBidFactory which creates AuctionBid objects and stores them into an arrayList
I have another Gui class which acts as a user interface where the user can create bids but then i want to compare the itemSet of the AuctionBid which is created by the user to the itemSets of the AuctionBid objects which already exist in the arrayList and if that itemSet does not exist in the arraylist then will add the new AuctionBid to the arrayList.
I have the following method in the AuctionBidFactory which is supposed to compare the itemSets of the AuctionBids in the arrayList and it does not work:
public boolean containsItem(AuctionBid auctionBid) {
          if (auctionBids.contains(auctionBid.itemSet)) {
               return true;
          return false;
where auctionBids is the arrayList where the AuctionBid objects are stored
I hope the information above is enough to see where the problem is.
many thanks

Amit, unfortunately I dont have a different object for the user bids. Basically I just have the AuctionBid(String bidder,BitSet items, int value) and the reason why im using bitSet is that im modelling a combinatorial auction where the bidder can bid on combination of items.
now when the user puts a bid that bid is added to an arrayList of ArrayList<AuctionBid>
then once all the bidings have finished i want to create autoBids for those single items only for which there are no bids. so for example lets say there are 6 items for auction and if there are the following bids in the arrayList:
AuctionBid(bidder1,{1},5)
AuctionBid(bidder2,{5},8)
i want to create autobids as follow:
AuctionBid(autoBid,{0},0)
AuctionBid(autoBid,{2},0)
AuctionBid(autoBid,{3},0)
AuctionBid(autoBid,{4},0)
and then i want to add these created bids to the same arrayList where all the bids are.
but if I use the arrayList.contains() method it will compare the whole objects to each other rather than just comparing the bitSets(items) in each bid.
so i dont know whether i can still do this without overriding the equals() method in the AuctionBid class or not

Comparing input value to array value for equality

Hi all,
I'm fairly new to java and I am finding this forum to be a great resource. I am learning more by seeing the problems others are having and the solutions. thanks ahead of time for the help.
Here is my problem.
I am using InputStreamReader and Buffered Reader to take keyboard input and add to a string ( lets call it name)
I then search an array for a match
for ( int i=0; i<array.length; i++
if ( name == array[i] )
blah blah blah
I can compile and run but my input never matches a value I know is in the array.
Do I need to do something to the input string to make it usable?
Any insight would be much appreciated

When comparing objects (including Strings) you usually want to use obj1.equals(obj2), rather than obj1 == obj2. The equals method uses semantics defined by each object to determine whether the contents are "equal". For Strings it compares the characters, for a MyEmployee class it could compare employee IDs or names, birthdates, and whatever else you decide is important.
The == operator, when used on references (anything that's not a primitive like int, float, etc.), tests whether both references refer to the same object. In your case, name and array[j] may have the same contents, but they're stored in two different String objects, so the == test fails.
Oh, and when you post code, use [ code ] blocks to format it, and don't use i as an array index (gives you italics) See

Comparing the BOM usage with the actual usage for materials.

Hi All
My client want to compare the BOM usage with the actual usage and have a report for this within a period? More specified they want to calculate the BOM usage, based on the requirement quantity from confirmation - but with out the scrap %. mulitplied with the confimed quantity of the header material.
The actual usage should be based on goods issuing from stock, either as goods issue to order (backflushing) or as goods issue to cost center.
I havent been able to indentiy a standard report for doing this - does some of you know a standard report?
- I was thinking of the following method:
Look at tabel RESB and compare it with MSEG, but I have some diferent problems with this.
- In resb there is no qty before scrap.
- The data amount from MSEG, is so huge so it is not possible to make a data search for a whole period (eg. month)
Br. M

There is one std report MCRX which gives a comparison of quanity in order and actual consumption,
if it doesnt meet your need, you may have to create a custom report.
logic can be find the quantites as per BOM for the produced quantities
issued quantities to the order
tables you may need are AUFK AUFM
AFKO, STAS STPO
MSEG, MKPO
JEST ( if you want to filter using order status)

Problem with ORA-24372 invalid object for describe

I have unresolved problem with oracle message: ORA-24372 invalid object for describe. There is the client-server application which installed on users PCs. Client application is program on Delphi 7 that installed on several users PCs which works with Oracle DB 10g server (clients on users side 8.1.7) by means ODAC 5.7. Each user by means this application works with data on Oracle server. Each group of users uses its own schema. Each of this schema has grants to select data and execute procs in the main schema. During the time of operation I modified and compiled some procs in the main schema. As the result I found some depended Invalid objects in main schema. I recompiled them. There is no invalid objects in all schemas. But when I starts application in one user place (he uses for example schema X1) I see oracle message: ORA-24372 invalid object for describe. Other users in group which uses schema X1 works without this problem. There is finite aggregate of users of schema Х1 which has this message but some users of schema Х1 has no problem. All users has identical software and there is no any invalid objects in schemas! I try to start application on my PC using schema X1 and finds ORA-24372 then I try to start application on neighbors PC and it is all ok! It happened after I recompiled main schema in the time of users operation. What should I do to resolve this problem? Where to find the source of the problem: in client or in server?

To Mr. Sven Weller
The purpose of creation X1 (X2, Х3…) was restriction of users to access objects in the Main Schema. X1 has no any objects except function that returns her name for internal purposes. X1 has many synonyms for objects in the Main schema. There is no invalid objects in X1!

Error in multiple operation with change document object for custom table

hi all,
I have developed a change document object for a custom table ZTEST and developed a report program for insertion, updation & deletion..everything works fine if I do only once ie. if I created only 1 entries. If I created 2 new entries , I am getting an Error "DUPREC:POS&Z3RL_TAB&Z3RL_TAB" and EXIT the transaction.
why I am getting this error??? is it not possible to do multiple operation with the change document???

Mapping and querying Custom Objects for a Contact with REST Api

Hello All,
We are hoping to get some details on managing DataCard set through REST APIs. Our implementation goal is to create Contacts and add Custom object for each Contact, or to be precise, add a DataCard Set for each Contact.
At the moment, to associate a DataCard Set (or Custom Object) to an existing contact, we are supplying following custom object fields during creation of Custom Object:
new CustomObjectField
                                                                name = "MappedEntityType",
                                                                dataType = Enum.GetName(typeof(DataType), DataType.numeric),
                                                                type = "CustomObjectField",
                                                                defaultValue = "0"
                                                         new CustomObjectField
                                                                name = "MappedEntityID",
                                                                dataType = Enum.GetName(typeof(DataType), DataType.numeric),
                                                                type = "CustomObjectField",
                                                                defaultValue = "<ContactId>"
Is this the correct approach? This is Based on the information provided here: http://topliners.eloqua.com/community/code_it/blog/2012/05/31/eloqua-api-how-to-mapping-a-data-card-to-an-entity.
Would the REST API allow us to query the CustomObjects using the MappedEntityId value for later updates? If so, any pointers on how we approach that?
Thanks in ad.

Either the MappedEntityID field is not available or I do it wrong, Eloqua is ignoring the field and does not map the custom record with the unique Contact ID
