Easy way to clone a Vector and its Content?

I have a Vector containing String Arrays. I would like to clone the vector an all it's content.
Just cloning the vector doesn't work, because just the vector gets cloned whereas the references to the StringArrays in the vector stay the same.
So i guess i have to clone all the StringArrays too? This would be a very "expensive" process, so i'd like to ask first, if there is another methode to clone a vector and it's content?
Thanks for your help!

No. Clone gives you a shallow copy. What you want is a deep copy. However, since Strings are immutable, you only need to deeply copy the string arrays, not the strings themselves. If you were working with mutable objects, this would not be the case and you would need to copy the items in the array as well as the array itself.

  • Is there an easy way to switch between ehternet and wifi connection without having to disconnect the ethernet cable?

    Hi All
    Was wondering if there is an easy way to switch between ethernet and wifi connection on Apple TV without having to disconnect the ethernet cable. The reason I ask is that I find it quicker to use my ethernet connection via a Netgear Powerline Home Theatre Set-up to stream Trailers and Movies on the Apple TV, however this is no good when connecting directly to my Mac to stream music or TV shows in iTunes, so revert to the wifi connection that I created on my Time Capsule to do this.
    Would be handy if Apple TV had a menu option where you could manually change the connection type depending on what you were doing, as per above scenario.

    Mac OS 10.5 /
    I deleted the " Private" folder ... and emptied the trash. So the folder and its contents no longer exists on my computer at all !!!
    I do have the OS 10.5 dvd that i purchased years ago...
    But my computer will not start from it on its own.
    My question is what is the open source or terminal language code used to tell my mac to look in the DVD rom drive for startup info?  I know that im not the only person in this world who has deleted the "PRIVATE" folder and emptied the trash so it no longer exists on their machine...
    That said theres gotta be a common fix for a Power PC G4 that has the OS X dvd in the rom drive but wont look to it to reinstall the vital contents of the PRIVATE folder.
    Once again there is not a copy of this file or its contents in the recycle bin...
    Also rebooting the machine , pressing and holding the letter C does not prompt the machine to look to the dvd rom drive.
    I was reinstalling pro tools and figured I would make some room by cleaning my computers HD...
    Lol It was a bad choice to delete this file ...
    Thanks guys

    Okay sorry it took forever to respond... But for a while there I gave up on this computer!!!!
    Money's been tight lately , so taking it in to a professional was not yet an option... though I did consider it eventhough.
    Anyway long story short im glad I didnt spend any money because I already had all the tools necessary to fix this issue but was going about it in the wrong way. Okay so here is my scenario and the breakdown... Though this may not fix the issue for everyone :( which *****... But I know we all will have different circumstances.
    Anyway here we go...
    Okay so first things first....  Years ago I purchased the OS 10.5.1 disk ... So that has always been in my possession!!!!
    I realize that some may not have a disk to reflash your OS to your hard drive... but if you do your in luck.
    2ndly ... I had an external harddrive with all of my itunes downloaded music so it was more than okay with me to delete my primary HD because all the important stuff could either be copied over or repathed to be located.
    -------If you dont want to read through the whole story the fix is summed up in the bottom section-------
    Okay so now the SOLUTION!!!!
    By trial and error , and pure boredom I opened up my computer to clean the inside...
    "Disconnected the primary HD"
    and just because ....... REBOOTED my computer. Just to see what it would do.
    Upon restart and though it looked like it would repeat its usual cycle...
    About 1 minute in to that process my computer froze for about 2 seconds and flashed to the OS installation screen.
    Mind you I havent seen this screen yet... Probably hasnt been since I installed the OS years ago.
    After a bit of trial and error...
    I decided to tell my computer to startup from the OS 10.5 disk located in my dvd rom drive and restarted once again...
    this setting is under
    Utilities / startup disk
    After a little more trial and error ... I realized that I could reconnect the primary HD , restart the machine and return to the OS installation menu.
    So upon this discovery
    I went to the Disk Utility located under Utilities
    Highlighted my primary HD located in the left hand column
    Once highlighted ...
    In the heading section on the right I selected the option
    in which I erased My current OS on my primary HD ...
    I used the first option in the list under security... Because it seemed like the least invasive and would take the least amount of time to see if this process would actually work.
    I FORGOT to add something... 
    Another reason why I deleted my primary HD!!!!!
    I forgot to say that it WOULD NOT!!!!! Show up in the STARTUP list as an option...Even After multiple reboots....
    But like clockwork... Once I deleted its name IT SHOWED UP as an option!!!!
    So back to the next step...
    I returned to the STARTUP option under utilities ... And was then able to see MY primary HD now as a startup option...
    But ofcourse it had no name because it we previously erased it.
    So when Clicking my newly erased HD ... I was almost immediately prompted to REINSTALL the OS ...
    Which said it would take about 57 minutes ... But I believe was alot less...
    My issue was resolved ... My computer then stated the install was SUCCESSFUL!!!!!!! :))))))))))) lol ;)
    It was like I was setting up for the first time ;) asking for my registration info...
    The dilemma of deleting the private folder and emptying the trash is finally over resolved. Done ... and no extra money spent!!!!!!!!! 
    Its really crazy that the information for such a simple thing is not readily available. Especially being such a simple fix.
    I know im not the only person who's had this issue , because i've seen numerous posts with similar wording.
    I also know I wont be the last person to have this issue... So I hope this synopsis makes sense.
    -------One more time the fix------
    *Insert your OS dvd into your dvd rom drive.
    *Unplug your primary HD or corrupted startup disk
    *Reboot your machine...
    Upon restart your primary HD will not be recognized...
    * you will then be prompted to select your language.
    Once selected
    *Click Utilities/startup... Highlight the the selection that refers to the OS dvd located in the dvd rom drive.
    * Click restart...
    !!!!!!!!!!Be sure to reconnect your Primary HD Before your computer restarts and you hear the chime!!!!!!!!
    If you do not replug your HD before the chime it will not be recognized.
    In that case restart again.
    Upon restart once again
    *Choose your language...
    *Click Utilities / disk utility
    In the left column select and
    *Highlight your HD ...
    Then towards the top portion / center of the page
    *Click the heading Erase
    Then on the page toward the bottom
    *Click security options
    This will then provide erase options.
    "Dont erase data"...
    *click OK
    * click erase...
    Once erased which should take a few seconds
    *Cancel the disk utility...
    * Click Utilities / startup
    And your newly erased HD should now appear in the list.
    * Select your drive from the list by highlighting
    It should no longer have a name.
    *Once selected, you will then be prompted to restart and install the OS to your newly erased HD...
    Thats it!!!!
    Once everything reinstalls re-add your personal info or registration info and you are up and running.
    Goodluck ;)

  • Is it possible to recover a deleted folder and its contents as opposed to an individual file?

    When I turned on my computer today, a folder located on my desktop is no longer there.  Astounded I could have accidentally deleted it, the folder having been trashed is the only illogical logical possibility I can think of - and is a first for me in my 30 years of Mac use.  My father is in the process of dying and the folder contains all the information coming to me on the subject.  The last backup of this folder is about a week old and much has been added since for which I've no record.
    Not having a master document or table of contents listing what was in the folder leaving me unable to search for and recover individual files/documents by name, my question is this:  Is it possible to recover a "FOLDER", and its contents after that folder has been moved from the desktop to the trash, the trash emptied, and the computer having been shut down?
    If anyone has any ideas of how to recover anything about what items that folder contained, I'd really appreciate whatever thoughts you might have.
    Thanks in advance -
    The computer this folder is missing from is a early 2008 MacPro, running 10.7.5.

    I'm not sure what you can do beyond trying to restrict the types of files you search for. These apps normally have ways to select the file types or to add example files. That allows them to carve out only those types, but you still may end up with GB's of data, especially if the types are somewhat generic. I don't know of any tools that can undo changes to the disk catalog over time.
    I guess you could also search for specific text if you know that these files contained something that is 'almost unique'. Spotlight can do that, or grep, egrep are command line tools that may help ask if you want to go that route, they may help you gather lists to move files around to whittle them down.
    Sorry I can't think of a way around this it's a difficult task at a difficult time. Good luck with it, ask if you think we could help.

    OS X Lion: About Auto Save and Versions - Apple Support
    @Tony T1, do you know how to restore files from that system? I think it is part of Time Machine, but the copies are saved locally.
    It is not entirely clear how it works (at least from my memory of Lion) with regards to how you could get files back in this situation. The database should be at the base of the disk in a hidden folder ".DocumentRevisions-V100", but I don't think you can just pull files out of there. Personally I'd consider making a full disk backup before you attempt to restore files. Then you could try the 'Enter Time Machine' UI to see if it can browse back to the older Desktop.

  • Is it possible to sign the transport and its content?

    Hey Everyone,
           Is it possible to sign the transport and its content when I release transport? So that when a particular transport is imported into destination system we can say with certainty that transport is not tempered with?
    I am more worried when we give data and cofile to be imported into some System it may be tempered with so that it may look like the same transport but its contents are modified. (I am not sure even if its possible for somone to modify these files and hence the actual ABAP Object in it are changed.)
    Of course, it is possible to sign the file content itself and send it over, but I am trying to minimize the risk even more so that when we release transport or when someone is importing it signing is automatically done or checked.

  • PSE9: How do I move/copy an Album and its contents from my PC to my laptop?

    I am using Windows 7 and PSE 9 on my PC and want to get a copy of the album and its contents to my Vista laptop running PSE 9 without changing anything on the source PC. Anyone know how to do this? I know I can move the files through Windows Explorer on my network but I have already gone through the trouble of putting the best photos into an Album and would like to simply move the Album over and not have to go through the trouble of recreating it.

    You will need to copy the files.
    1. Make a new folder on your laptop
    2. Open Organizer, select your Album then press Ctrl+A to select all photos
    3. Click the Fix tab and choose Full Photo Edit to open the album contents in the editor
    4. Click File >>Process Multiple Files
    5. From the drop down menu (Process files From) choose Opened Files
    6. For destination click the browse button and navigate to your new folder on your network and click OK
    7. Make sure Rename and Resize is unchecked but check Convert files To and choose Jpeg Max quality or whatever you prefer then click OK and wait for Elements to finish.
    8. Go to your laptop folder to see your images.

  • Deleting a directory and its content

    Hi, I'm trying to delete a series of directories like this batch file does

    or would it be better to call the batch script with Runtime.exec()? The system is windows only so i don''t need to have compatibility with *nix shells ect.
