How to implement a time watch for an object

Greetings!
I have a container called TupleSpace which consists of elements of type Tuple. Among the attributes, the Tuple also has a "time to live" (the maximum amount of time its presence is allowed on the TupleSpace). After this amount of time passes it should be automatically deleted from the TupleSpace. My question is: what is the best mechanism to implement this ?
My solution so far looks like this:
public void removeExpiredTuple(){
// ts = instance of TupleSpace class
          for (int i = 0; i < ts.size(); i++){
               ITuple currentTuple = (ITuple) ts.elementAt(i);
               long tupleAge = System.currentTimeMillis() - currentTuple.getTimeSubmitted();
// currentTuple.getTtl() = retrieves the Tuple's "time to live"
               if (tupleAge > currentTuple.getTtl())
                    ts.remove(i);
     }but I am not at all satisfied with it
Thanks in advance for your answers

How to Implement a Time Limit Feature in an Online Test Application ?

I am creating an Online Test application. The time limit can be stored for a Test in the database.
How to implement a time limit such that when the test is started (user clicks on the Start button to go to the fragment containing the Questions) the time left is shown and the test ends (goes to home page) when the timer reaches zero.
Thanks

Hi,
timestamp is a date and thus cannot be used directly to determine seconds passed. So what you need to do is to build the difference between a saved time stamp and the current time.
http://docs.oracle.com/javase/1.4.2/docs/api/java/sql/Timestamp.html
So if you have two time stamps, then calling getTime() on each and building the difference gives you a value, which is millisecond. So to get this to an int value you divide it by 1000

How may implementations can we have for a BaDI?

How may implementations can we have for a BaDI?

if BADI check Multi-USE , then u can
Multiple-Use Business Add-Ins
You can differentiate between single-use and multiple use Business Add-Ins. The distinction is based on the procedure or event character of an enhancement. In the first case, the program waits for the enhancement to return something, usually a return code. A typical example could be a benefit calculation in HR. Depending on the implementation, alternative calculations can be executed. With multiple use add-ins, an event that may be of interest to other components is processed in program flow. Any number of components could use this event as a hook to hang their own additional actions on to.
In addition to importing parameters, you can also use changing parameters for multiple-use Business Add-Ins. There is no sequence control for multiple-use implementations of BadIs. Therefore, using changing parameters can cause problems. There is no guarantee that implementations will not overwrite the results of previous implementations. Sequence control is technically impossible, since at the time of the definition the interface does not know which implementations there will be and which parameters will be changed by implementations. It is not possible to have a decision as to which implementation should be executed before which other (future) implementation.
Example:
In a particular application, you want to be able to continue processing indexes after another component has saved data (in other words, the system should allow you to use an add-in after saving). Since this point in time can be useful for different purposes, you can create an enhancement here that can be used by multiple subscribers.
To create a multiple-use Business Add-In, proceed as follows:
       1.      Define an add-in and select the Multiple Use checkbox from the Administration tab.
       2.      Define an interface with the method OBJECT_SAVED'and the importing parameter OBJECTNAME.
Calling your enhancement in the application program:
program event.
data exit_obj type ref to if_ex_event.
call method cl_exithandler =>get_instance
     changing instance = exit.
form save_object using obj_name type c.
update
call method exit_obj->object_saved
     exporting objectname = obj_name.
endform.
For the caller it is irrelevant whether (and how many) subscribers use the event as a starting point for further actions. The active implementations are called in the adapter method.

Unfortunately no. I asked the same question when I went to the local Apple Store for my "try on" and as of now you would have to order the watch with the metal link band and the black sports band separately.

How to Implement the Search page for Workflow Notifications?

Hi All,
I want to implement the new Search page for Workflow Notifications. Search page containing Company, Paygroup, Source, Initiator, Supplier Name, From date & To date fields. These fields(Poplist & Calendar) are getting the values from different tables and these fields are not in WF_NOTIFICATIONS table only Initiator & dates are there. After selecting the values in all fields or one field based upon these values I want to display the all Workflow Notifications ( Those are satisfy the search criteria only not all ) in Advance Worklist Table RN in the Notifications page. Is it possible to create the Search page based upon the above scenario if Yes Let me know how to implement this search page for Workflow. Page was designed but how to get the sortlisted Notifications and how to pass these values to next page?
Thanks in advance.

How do I set time limits for my iphone?

You know how there are parental controls on the macs in the settings. In there you can set up time limits of how long you can use the computer for but I can't find it on the iphone where you can set time limits for use. I looked at the restrictions sections but I don't see anything on setting time limit. How could I set time limits for use on my phone? I go on my phone too much and I really have to set restrictions to limit my time on it.

There are apps you can download i believe to do this.

How to set the Default values for Info Objects in Data Selection of InfoPac

Hi All,
Flat file Extracion:
How to set the Default values for Info Objects in Data Selection Tab for Info Package
ex: Fiscal Year Variant Info Object having values 'K4' 'Y2' etc in Flat file
Initially default value(not constant) for this info Object value should be 'K4' in Info Package
If I set data selection value for this info object K4 it will retreive records with this selection only? how to handle
Rgds,
CV

Hi,
suppose as your ex. if you are having fiscalyear variant in the dataselection tab then specify K4 in the from column, again the ficalyearvariant row and click on insert duplicate row at the bottom . you will get another row . In that enter Y2 in the from column. now you can extract K4, y2 values .
