Sorting the values of a map.

I have been stuck on this problem for a while. I have a TreeMap, which can be changed to a HashMap if needed, with a set of keys as Strings and values which are Integers.
EXAMPLE
String1, 123
String2, 333
String3, 222
String4, 758
I need the values sorted in decending order (9-0).
Thanks in advance for all your help.

I have been stuck on this problem for a while. I have
a TreeMap, which can be changed to a HashMap if
needed, with a set of keys as Strings and values which
are Integers.You must be the first one who changed a TreeMap into a HashMap and then lived to tell about it. -:)
Anyway a TreeMap is always sorted on key, not value. To have your dataset sorted on value you must reload into another TreeMap and invert the key/value pairs in the process. The values then become keys in the new TreeMap which means that the former values must be unique for this to work.
I'm sure there's a simple solution but it's better if you described what you want to accomplish in general terms than to let people struggle with a solution scenario that's probably suboptimal. How do you want to access your objects and why and when do you need them to be sorted.

Sorting the values in Map

Hi,
In my application, i want to use Mapping in the case
Key -Value
A - 2
B - 3
C - 7
D - 5
For that I used HashMap. But I want to sort the values and place in map as from Highest order. For that in google it is suggested to refer SortedMap. But this SortedMap is sorting the Key content only not Value content.
For sorting the Value's what I have to do under Collection?
Any idea?

I am having a String array; a[]={qw,q,as,l,kj,q,q,l}
From this i am mapping
key value
qw 1
q 3
as 1
l 2
kj 1
using HashMap.
From this I want to fetch q whose value is greater. How can I do this?
Hope this explains better.You still haven't said how often you want to do that. What I explained will work, but it might not be what you want if you often change values.

Sort the values in Bex query variable screen

Dear Experts,
Is it possible to sort the values of a dropdown list for variables on BEX variable selection screen ?
For example, For calender month selection, the values are by default sorted by ascending order.
Is it possible to sort by descending order ?
Regards,
ravindra

Hi Ravindra,
yeah it is possible by writing an abap code for the field calmonth/week...etc this is depends on the F4 help of the selection field. so you need to write a code for F4 help for making it in descending order. hope it helps.

Sorting the values in the HashMap maintaing the key-value relationship

Hi,
I want to sort the HashMap based on the values. I have tried several other ways but the closest I can get is sort the values but have to loose the keys. I wanted to sort the collection based on the values but at the same time maintain the key-value relationship. Is there any way I can get this functionality either by using any collection API or by some other way?
Thanks and appreciate your help....

Sorting the values in a column in a Web Template Report

Hi All,
I have a report build on WAD in which a table is displayed with certain rows and columns and have certain text values in one column and few numeral values in the other few columns. When i right click on the 1st column(having text values) and click on Sort Ascending by Name, the values are sorted in groups.There are other 3 columns next to that column which have text values as well but when i right click on them and try to sort it in some order(ascending by name/descending by name), there are no reorganization of the values in the column. Again, once i go to the other remaining columns having numeral values in it, the values get sorted in ascending/descending order as per the sort selection. Please advise on how i can make the sort possible in the columns in which the rearrangement is not happening. Do i need to change the Query to some settings? Please advise.
Thanks!
Subhra Ghosh.

Subhra,
In BW reports, the sorting of characteristic values always happens left-to-right. When you choose to sort by columns 2 - 4, you are actually just specifying whether to sort ascending|descending and/or by key or text. This sort happens for each value of the first column, however. Therefore, the sort in column 2 is only noticeable when you have more than one row with the same value in column 1, etc.
This sorting behavior is different than the Excel type of sorting, which may be your confusion here.
If you want to sort first by a column other than column 1, you must swap the columns so that the desired characteristic is in column 1.
Hope this helps...

Sorting the Values in Dropdown box values in dashboard

Hi,
I have a small problem. In the dash board I have a drop down which will displays the list of the employess. How to assign the sort to this. I have checked all the option but in the web application designed I didnt find any option for it.
Please help me in this.
Thanks
naveen

Yes, you can do this by specifying this parameter in your web item.
<param name="ONLY_VALUES" value="X"/>
This will return all the objects as part of a form so you need to write your own html form around this.
To sort this within javascript, the easiest thing to do is convert this list of form values to an array, sort this array, and then re-render the form values. There's an example online of doing this with a table here:
http://javascript.internet.com/forms/sort-data-table.html
You could do this with for a form in a similar manner.

Sort the Valuenode records in table

Hi Experts,
Following is the code I wore to retrive and display Portal roles in a table. The context maintained is as follows and got the results properly. I want to know how to sort the table values by Role_Name?. Could some one help me?
[Value node]      Role_table
[Value Attribute] RoleID
[Value Attribute] Role_Name
[Value Attribute] PCD_Location
//Retrive the roles from the Role factory
String[] theroles = rolefact.getRolesOfUser(unique_id,true);
for(int i=0; i<theroles.length; i++ )
//Retrive user attributes and add to the context attribute values
String roleid = rolefact.getRole(theroles<i>).getDisplayName();
String rolename = rolefact.getRole(theroles<i>).getDescription();
String role_desc = rolefact.getRole(theroles<i>).getUniqueName();
IPrivateUserView.IRole_tableElement rowelement = wdContext.createRole_tableElement();
rowelement.setAttributeValue("RoleID",roleid);
rowelement.setAttributeValue("Role_Name",rolename);
rowelement.setAttributeValue("PCD_Location",role_desc);
//Append the roles obtained and bind to the rolenode
al.add(rowelement);
wdContext.nodeRole_table().bind(al);
Please help me with some code on how to sort the value node table?. I promise to award the points for the right solution. I appreciate coding help.
Thank you
Regards
Maruti

Hi Maruti,
1. Get the size of the node, save it in a variable say <b>si</b>
int si = wdContext.nodeRole_table().size();
2. Iterate as follows
for(int i=0;i<si;i++)
     for(int j=i+1;j<si;j++)
         if(wdContext.nodeRole_table().getRole_tableElementAt(i).getAttributeAsText("Role_Name").compareToIgnoreCase(wdContext.nodeRole_table().getRole_tableElementAt(j).getAttributeAsText("Role_Name"))<0)
         wdContext.nodeRole_table().swapElements(i,j);

Sort the Key Figure and put a count on it

Hi Experts,
I have a situation where I have to sort the value of the Key Figures in ascending order and put a count on them.
Kindly elaborate me a little on this.
Thanks in advance,
Kannan

Hi Kannan,
If you want to do this setting at the Query Designer level, then select the Properties section for the
desired Key figure say K1.then select the "Calculations " tab. Under the Local calculations for "Calculate Results as" select "Counter for all detailed values".Save the query.
Open the query (say) at Bex Analyzer. From the context menu for the key figure K1, select "Properties"-->then under Sorting tab select the required order.
The options mentioned above, i.e "calculations" and "Sort" is available on web too in the context menu for the key figure.
The above mentioned setting wil be a display setting>You can modify it as per your requirement at Query Designer.
NOTE:
If your requirement is such that K1, should always display the counter , then while creation of the K1 itself , you can select the Exception Aggregation of Type "Counter(all values)". Then, the setting will be permanent.(design time)
Hope the information helps!

Akshata

Sort the Shortcut Dropdownlist of Team Member Home Page in Oracle Project

In Team Member Home Page, need to sort the values in the Shortcuts dropdown list.
I have checked the VO(ShortcutDroplistVO), which is used as Dummy VO.
Checked the ShortcutDroplistAM,ShortcutDroplistRN,ShortCutDroplistCO, which is attached to the Shortcut field.
Shortcut Dropdown list values are not given in Controller class,View Object.
I am confused how the values are populated dynamically?
Could anyone help me to solve this issue?

There are two ways to go ahead:
First one:
1. Extend controller and in processRequest get ShortcutDropListVO object
2.get the query using vo.getQuery()
3. Add orderby caluse to the query and set it using vo.setQuery()
But vo.setQuery() may or may not work properly.
Second one:
1. Create custom VO(as required) in Jdeveloper under custom folder structure and move it into server
2. extend controller and in processRequest attach custom VO to seeded AM (you can get sample code in many threads)
3. get drop down bean value and attach custom VO to it using sample code
OAMessageChoiceBean bean = (OAMessageChoiceBean)webBean.findChildRecursive("beanID");
bean.setPickListViewObjectDefinitionName();
bean.setPickListCacheEnabled(false);
Note: custom VO should have same columns and order of columns as seeded VO
