• How to implement a list linked in oracle?

  Hi all
  I want to know if there is a way to implement a list linked in oracle?
  Thanks in advance
  Naama

  Oracle built the collections (nested table, associative arrays) will act as lists related to you. They already have the pointer to the previous values and following, built in. It's been long since I worked with linked lists, but I can't think of anything that they could do a nested table or associative array failed.

  Small example of using a table as a nested list chained:

  DECLARE
       TYPE nt_t
       IS
            TABLE OF PLS_INTEGER;
       nt nt_t := nt_t(1,3,5,7,9);
       i PLS_INTEGER;
  BEGIN
       -- delete some elements
       nt.delete(3);
       nt.delete(4);
       -- walk list forward
       i := nt.FIRST;
       WHILE i is not null
       LOOP
            dbms_output.put_line(nt(i));
            i := nt.next(i);
       END LOOP;
      -- walk list backwards
       i := nt.LAST;
       WHILE i is not null
       LOOP
            dbms_output.put_line(nt(i));
            i := nt.prior(i);
       END LOOP;
  END;
  

• How to implement the list of values

  Hello
  
  I use Jdeveloper 11 g.
  
  Now I have two attribute LOV. an attribute is a continent and a country. If I select a continent, the country attribute is a list of the countries of a particular continent (another country is not showing the user). If I select the second attribute medium Asia countries like China, India, Russia, pakisthan only shows. other countries there has no need to display this attribute. (Apply a model layer itself) How to do this, give an idea.

• Implementation of collapsible list, cannot set field

  Hello

  I implement foldable list by using managers and field:

  -When the cell is developed, a data provider returns a list of the fields to add as the child cells, and they are inserted into the vertical field Manager.

  -When the cell is reduced, the child fields are removed from the Manager of the vertical.

  -The data provider is fetch field on the web properties, so it is an asynchronous process

  Everything works well except:

  -For the passage to the next screen and back n trying to expand, collapse of the cells, the JDE console says:

  WARNING cannot field layot, insufficient height or width

  And new fields are added to the Manager of you but not drawn on the screen

  Help, please

  Thank you very much

  Sorry for reply late cos I was on vacation.

  My problem is solved without changing the code of the user interface (my managers already had vertical scrolling properties) defined.

  The problem was related to the operation of the network and the listeners.

  Sorry for the confusion.

  Although every thing is good, but I always get warnings and I don't know why.

  Thanks again.

• Is it possible to define an exceptions list of cookies that will not be deleted and disable any cookie?

  I installed firefox to clear all cookies when firefox is closed, and this is how I want to keep it. However, there are a handful of sites where I don't want the cookie to be deleted. I also want cookies from these sites to update when I visit websites, so I can not simply copy them to another folder.
  Is it possible for me to implement a list of exceptions to the rule "delete all cookies in closing?
  Thank you
  Chris

  In Options-> Privacy .

  1. In the section accept cookies , set keep until: I close Firefox. This will make all cookies expire when Firefox is closed.
  2. Add domains you want to keep to the Exceptions list, choose "allow". (example: "mozilla.com")
  • If you use the feature delete history Firefox closing , make sure "Cookies" is not checked in the settings..., as this setting overrides your Exceptions list and delete all cookies when leaving.

• effective horizontal lists with scroll

  Hello

  I have a group of images which I want to display in a horizontal list, the size of the list will vary depending on what option a user selects.

  However, I'm not sure of the best way to implement a list if I have a large number of images to provide an it, therefore generating a lot of areas that need to be drawn.

  My idea of making the effective list:

  -Store the images in a circular table.

  -Display the first 3 images on the screen in3 views that are visible to the user (for example <-- img1=""  ="" img2=""  ="" img3="" --="">)

  -Keep a record of what is exposed...

  -When a user scrolls left or right the next/previous image in the table is displayed.

  For example scrolling right once will give me ( <--  img2=""  img3="" img4="" --="">)

  For example scrolling left 3 times from the point above will give me ( < --="" img(n-1)=""  img(n)=""  img1="" --=""> )

  and so on...

  What would be the best way to do what above, or are there better ways?

  I would be grateful if someone could direct me to the relevant documentation, methods of the api should I use as well.

  Is there already a method in the api that can recycle the views in the same way...?

  I would be grateful for any help.

  Thanks in advance.

  Answer:

  PictureScrollField:

  "A slider component that draws a line of images that can be the object of one scroll from side to side using the trackball or touch gestures. The images drag horizontally to align the focus vertically centered image. Images decelerate they approach their new position to give a lively effect. There are also several configurable effects to highlight the image update.

  All images are awarded the same amount of space on the cursor (as defined by imageWidth of the manufacturer and the imageHeight settings). Images may differ from this size, in which case the scroll field behaves as follows:

  Images are NOT resized. If they are larger than the allocated drawing area they are center aligned and cropped to fit the allotted area. If it is smaller than the drawing area allocated, they are centered in the allocated area. »

• Complex drop-down list

  I want to implement a drop-down list with 20-50 points, and each line item will have a fairly complex together information to display, including images and text loaded from the web, text and images loaded from the device.

  I searched a bit on the forums and noticed people had two main approaches.

  Custom VerticalFieldManager or a custom ObjectListField where they replace the drawListRow function.

  With regard to the application of something as they are only two options I have? And in terms of performance, which one would be better to implement a list 20 + points, where each line has a fairly complicated layout?

  Thank you.

  I use the objectlistfield in virtually all applications, so I wrote my own extension of the listfield class. It offers many advantages, for example to add a vector, define a vector, customization of the color of the setting to the point or the extraction of the selected object. can not share the code of course, but it is otherwise difficult to perform and easy to improve them if necessary.

  I would recommend that you take an hour or two and implement an objectlistfield as desired, can save a lot of time later.

  With regard to the different heights: you can use the hidden setRowHeigt (index, height) method, but I wouldn't recommend it.

• Drop-down list LOV shooting required field validation

  Hello
  
  I use Jdev 11.1.1.6.
  My VO is based on entities. I have 3 domains in this VO as F1, F2, F3
  3 fields are required.
  F1 has Combo Lov-based model implemented. List attribute LOV lookupId returned to F1 and the attribute List lookupDesc at F2.
  F2 is mandatory and can be changed. Idea is that the default text returned by lov and then user can update the description.
  
  Scenario 1: does not work >
  During execution, in mode, create when I try to select a value for this lov combo, it triggers the validation of required field for F2 (only for F2 and F3 not) and does not display the list of values. I can't do to show the list to enter some data in F2.
  < af:inputComboboxListOfValues > a autoSubmit = 'true' and immediate = "false" and a partialTriggers F2 = "id of F1".
  
  Scenario 2: < work >
  For test purposes, if I do unalterable F2 it works perfectly but F2 is editable and mandatory as well.
  < af:inputComboboxListOfValues > a autoSubmit = 'true' and immediate = "false" and a partialTriggers F2 = "id of F1".
  
  Scenario 3: < work >
  On other pages, I've implemented combo lov where the lov is implemented on the reference field and the return value only the Id column and not in any other field. This scenario works perfectly, even with the mandatory fields on the page.
  < af:inputComboboxListOfValues > a autoSubmit = 'true' and immediate = "false".
  
  
  Thank you
  JAI

  Try to remove F2 partialTrigger (a partialTriggers = 'F1 id'),
  and join valueChangeListener on F1, in which you can refresh partially F2 (in code)
  Of course, do autoSubmit F1.

  Scenario 1:
  During execution, in mode, create when I try to select a value for this lov combo, it triggers the validation of required field for F2 (only for F2 and F3 not) and does not display the list of values. I can't do to show the list to enter some data in F2.
  a autoSubmit = 'true' and immediate = "false" and a partialTriggers F2 = "id of F1".

• Cache.get (Object) when using the list and Arrays.asList as keys

  Hello
  
  I saw a problem when doing the cache.get (object) with the list. Here's my test.
  
  NamedCache cohCache = CacheFactory.getCache ("Test");
  
  Key is a list
  Key list = new ArrayList();
  Key.Add ("A");
  
  cohCache.put (key, 1);
  
  System.out.println ("Get with Arrays.asList:" + cohCache.get (Arrays.asList ("A")));
  System.out.println ("list:" + cohCache.get (key));
  System.out.println ("list is equal to Arrays.asList:" + Arrays.asList("A").equals (key));
  
  Actual output:
  
  Get with Arrays.asList: null
  List is equal to Arrays.asList: true
  Download list: 1
  
  Expected results:
  
  Get with Arrays.asList: 1
  List is equal to Arrays.asList: true
  Download list: 1
  
  
  Arrays.asList("A") and the key are equal but consistency does not return the value. I thought that, in cache.get (object) consistency returns if object.equals (key) is true.
  
  Any idea?

  Hi Eric,.

  There is a slight misunderstanding in how you think that the works of coherence.

  For clustered caches Coherence does not return the value of the object key of equals to the key specified when caching, object instead, it returns When serialized forms of the key used to and used to get equal to one another.

  If you use no POF, then most of the time Java serialization is used to serialize the objects of key, and in any case if you don't use of POF, and the name of the serialized object class is in the serialized form.

  Now, the thing is that the key that you put in is a java.util.ArrayList. The key that you have tried to get with is a java.util.Arrays.ArrayList.
  It's two different classes, so the serialized forms that store the name of class implementation (which is true in this case) cannot be the same. So consistency is not going to put initially entrance the key that it uses (the serialized form) is actually different from the original key, so there is no entry for the key used in the get() method, and correctly you get back null.

  On the other hand, the two implementations ArrayList implement equals as defined in AbstractList, requiring not only the types of implementation of lists be the same, they apply just that the relation to the object is also a list, so two lists containing the same elements in the same order are equal as long as equals() on AbstractList is concerned, that's why your equals() check evaluates to true even if the types of implementation are different.

  Best regards

• Code folding list

• get (int index) method. in the list linked?

  In the linked list, there is a get (int index) method. Linked list does not use the index. It's just group of objects link where each link contains the following address. Here, my question is when api doc reference get element at index 2 here what it means get the next object of link?

  JavaFunda wrote:
  Thank you baftos. Actually my intention by the question is just to clear the fundamental band, which here means the index is not related to array sort index?

  A list is a classified as Collection. This means that what is implemented, a list has a 1st element element and a 2nd and so on up to however many elements is in the list. In other words, if you loaded, add (B), (C) add, you know that you can reference A as "the element at index 0" and C as "element at index 2. And you know that when you iterate over this list, items will come out in this order. (Note that with other Collections, such as whole, it is not true).

  This index peut correspond directly to the index in a table, but it should not. The mapping between the abstract index which is exposed publicly and the actual mechanism that implements it is a detail that we, users of the list, do not know or care. In an ArrayList, Yes, this index is the index in the array of support.

  But in LinkedList, there is no table support. So there must be a different mechanism to implement making reference to an element by index. LinkedList, i.e. Since the beginning of the list and the following pointers, such as let's go, until our count reached the index 'next' wanted. That is why the journey of a LinkedList with the get() method is O(N^2).

• Problem with &lt; Mx:List &gt;

  Hello

  I had a problem with the list control in flex. I'm trying to implement a list of a few names where the user can select each name by clicking on the item in the list. My question is if the list with the same name then not able to select the items in the list. (The same reversal isn't the case)

  Here is the code:

  ? XML version = "1.0" encoding = "utf-8"? >

  " < = xmlns:fx s:Application ' http://ns.Adobe.com/MXML/2009 "

  If the list of the various inputs, then I can roll over each item and select the wanted item. But if the list with the same name and then everything goes wrong.

  Is there anyway to fix this? Help, please

• Free / Smooth Scrolling list magnetic

  Hello

  How you would implement a list which smooth rolls (without attachment).

  The user must be able to scroll freely, but when it stops view list should align slightly (as trhe magnetic lines) to its line.

  ensure visual consistency (always display whole lines) is always maintained.

  Kinda like a "wheel of Fortune".

  Idea?

• List of States causing the change of State of scrolling

  Hello
  I need a list where each line can be enlarged/reduced to show/hide the additional data. I need to use something like a control list for performance (i.e. cannot use repeaters), and I've implemented a solution provided here:
  http://weblogs.Macromedia.com/pent/archives/2006/04/a_list_itemrend.html
  However on this solution when extending the first 3 lines and then start scrolling, the States change. The same happens on my own custom solution. I tried to put in place currentStateChanging event to pick up the target of the event but you do not. I don't know why this happens, but starting to think it's a matter of Flex that don't have a resolution?
  
  Any ideas or suggestions on how to implement my list or popular explanations?
  Thank you
