Tree Structure V Linear List
I am designing a new program and am examining the various data structures that are available for use. This program I am desiging is basically a database, with various attributes of and employee - eg Name, Id, dept etc.
What are the advantages & disadvantages of using the tree structure to store this data instead of using the standard linear list?
Many Thanks
Ok, if you're a programmer or even maybe a software engineer you SHOULD definetly know what the advantages and disadvantages are. Heck, you should even know what the runtime complexity, in standard "Big-Oh" notation, of a search for each structure.

Linear List or tree structure?
I am quite new to Java and am studying various data structures. What are the adavanatages over using the binary search tree to a standard linear list?
Many Thanks
AlanShort answer: speed.
Long anwer: a binary search tree is a balanced tree, i.e. for every node N in the tree and its left and right subtrees L and R respectively, the number of nodes in L and R are (about) equal.
This implies that after every comparison, half of the remaining nodes can be safely ignored and need not be compared. After the first comparison in a tree storing n nodes, n/2 nodes can be safely ignored; after the second comparison n/4 nodes can be ignored. So, searching a binary tree takes O(2log(n)) steps at most.
Compare this with a linear list storing n elements. After the first comparison (if the value wasn't found) you still have to search n-1 elements, after the second comparison, still n-2 elements have to be checked. So, searching a linear list takes O(n) steps at most.

// Call method again (recursion) to get the child itemsHi,
According to your post, my understanding is that you want to custom action for context menu in "Site Content and Structure" in SharePoint 2010.
In "SiteManager.aspx", SharePoint use MenuItemTemplate class which represent a control that creates an item in a drop-down menu.
For example, to create or delete the ECB menu for a list item in
"Site Content and Structure", we can follow the steps below:
To add the “My Like” menu, we can add the code below:
<SharePoint:MenuItemTemplate
UseShortId=false
id="OLListItemLike"
runat="server"
Text="My Like"
ImageUrl="/_layouts/images/DelItem.gif"
ClientOnClickNavigateUrl="https://www.google.com.hk/"
/>
To remove the “Delete” menu, we can comment the code below:
<SharePoint:MenuItemTemplate
UseShortId=false
id="OLListItemDelete"
runat="server"
Text="<%$Resources:cms,SmtDelete%>"
ImageUrl="/_layouts/images/DelItem.gif"
ClientOnClickScript="%SmtObjectDeleteScript%"
/>
The result is as below:

Do you have [red hair|http://www.dennisthemenace.com/]? ;-)
My advise with the tree structure is pretty short and sweet... make each node remember
1. it's parent
2. it's children
That's how the file system (inode) actually works.
<quote>
The exact reasoning for designating these as "i" nodes is unsure. When asked, Unix pioneer Dennis Ritchie replied:[citation needed]
In truth, I don't know either. It was just a term that we started to use. "Index" is my best guess, because of the
slightly unusual file system structure that stored the access information of files as a flat array on the disk, with all
the hierarchical directory information living aside from this. Thus the i-number is an index in this array, the
i-node is the selected element of the array. (The "i-" notation was used in the 1st edition manual; its hyphen
became gradually dropped).</quote> -
How to create a tree structure using list items(tlist)
HI every one,
As we know how to create a tree structure using Hierarchy item type.
We have a requirement to create The same tree like structure using List Item(Tlist)
I would be so appreciated If you send with an example
Thanks
RangaReddyHi all
Any one help me please
Actually our client requirement is creation of tree structure using list item,similar to what we used in oracle Application(FNDSCSGN) form.We did the tree structure using hierarchy tree using Htree and Ftree.It working excelently.For client requirement, we want to use list item.How PJC(Pluggable Java Components) is useful for using list item(Tlist).I can't understand how it is useful.
Do you have any example please help me.

How to get Tree structure in JSP page?
Hi,
I would like get data from the database and display the data in tree structure with the check boxes at each nodes on a jsp page with out using any third party tools. how can i do that? Do i require any new tags to fulfill this requirement?
can any one help me out by sending any example code?
thanks in advance.
Regards,
ReddyOnce you have the data in a list or something, can't you just use <c:forEach> and then output standard nested <ul> and <li> tags to give the tree structure.

JPA - tree structure mapping with toplink essential
I'll try to explain it correctly.
I store a tree structure in a database. I have just two tables:
Node which contain a id , and some other info.
Tree which contain a parent and child
parent and child are ids from node.
Since each node can have several childs, and each node can have several parents, I had try a @ManyToMany relationship without sucess.
Here one small example of my tries :
@Entity
@Table(name="node")
public class Node {
@Id private int id;
private List<Node> childs;
private List<Node> parents;
@ManyToMany
@JoinTable(name="Tree")
public List<Node> getParents(){
return parents;
@ManyToMany(mappedBy="parents")
public List<Node> getChilds(){
return childs;
}But I always got several error.
Anyone have a working example that look like mine ?
Even after googling for several hours I still find nothing.
If it helps, I use toplink essential for my persistance layer.Please see http://www.oracle.com/technetwork/middleware/toplink/index-085257.html for information on TopLink JPA support.
So as of TopLink 11, you will need to use EclipseLink's org.eclipse.persistence.jpa.PersistenceProvider as the provider class for JPA support, which is in the eclipselink.jar.

How to create tree structure in abap
hi,
I am mohan. Please send the how to create the tree structure. how to insert the child nodes in root node. actually our requirement is we have list transaction codes. We are planning to put all transaction codes in tree level.
please tell me how to do the program in tree structure.Hi Mohan,

Hi experts,
can any one give me sample code for providing tree structure in f4help. like object part field have in iw21 transaction
Regards
reddyHi Muttukundu,
SAP has provided a lot of sample programs for developing tree structures. Just go to SE38, type BCALVTREE and hit F4. You'll get different sample programs with a range of operations on trees
Go through the link,
http://www.sapdevelopment.co.uk/reporting/alv/alvtree.htm
Slowly check this code..you will get idea of how to develop tree structure.

SE80 : Source for the tree structure display for any type of Object
Hi Experts ,
I have developed a report which takes in a TR .Given a TR , I get the list of objects under it from table e071 table .
Now , I need all the objects (includes,screen,status,etc) related each of this object . SE80 perfectly does this in the form of a tree structure but now sure how.
Is there any Standard Table in which this information is stored or any FM/Method using which these details can be retrieved ?Hi,
You may use this tool : [SDN wiki: ABAP program to read where-used lists|http://wiki.sdn.sap.com/wiki/display/ABAP/ABAPprogramtoreadwhere-used+lists ]

Save tree structure to text file and load textfile to another tree control
I'm able to save the structure and data to a text file, thanks to the "save tree structure to textfile" info found on this msg board, but can't seem to load the complete tree structure data from the text file into another tree. I've only been able to load parent data but can't get the hierarchy of the tree with the indents and child data to work.
ThanksThanks Tanya,
However, I'm still stumped on how to copy (from text file) to other columns in the tree (from one tree to another). I can only get the first column to load.
I've attached my working VI and a textfile that I use to load into the "User list" tree.
Rick
