What does hiding mean for generics in this situation....

The type parameter Object is hiding the type Object
public interface PipelinePiece<Object> extends Listener<Object> {
    public void setListener(Listener<Object> l);
}I know this is not the most ideal code and E or something might be better than object, but I was having other problems writing a few classes that tie together as generics. I am just curious about the above warning and if there is a correction I can make to get rid of it?
thanks,
dean

but what if you want to deliberatly have a subclass that only accepts Listener<Object> or Listener<String>, etc. etc. Is this not possible then? or not advised.

  • What does "played" mean for podcasts and tv shows?

    What does "played" mean for podcasts and tv shows, in terms of the settings menu where you say to synch only "unplayed" shows? Does it mean you started playing it, or that it has played all the way through?
    And how does this relate to the "dots" next to podcasts in the menu? These dots seem to go away when you start listening, but do not finish, a podcast. Is this the same as "played"?
    Thanks!

    You are probably seeing a USB cable under the iTunes icon. This means the Apple TV is having problems and needs to be connected to iTunes to be Restored. http://support.apple.com/kb/HT4367

    what does it mean when you get this message on the Iphone? "online maps consume data traffic"

    That means that if you use online maps, it will consume data. If you're on WiFi, no worries. If you are on cellular data, then it will eat into your cellular data plan.

  • What does "wheel" mean for custom access

    What does "wheel" mean when allowing custom access to a folder?

    wheel= admin
    In computing, the term wheel refers to a user account with a wheel bit, a system setting that provides additional special system privileges that empower a user to execute restricted commands that ordinary user accounts cannot access. The term is derived from the slang term big wheel, referring to a person with great power or influence. It was first used in this context with regard to the TENEX operating system, later distributed under the name TOPS-20 in the 1960s and early 1970s.
    The term was adopted by Unix users in the 1980s, due to the movement of operating system developers and users from TENEX/TOPS-20 to Unix. Modern Unix implementations generally include a security protocol that requires a user be a member of the wheel user privileges group in order to gain superuser access to a machine by using the su command.

  • What does a * mean for checktable in dd03l?

    I  am looking at dd03l, there is a column checktable which tells the check table
    For the filedname in a given table tabname.
    I have seen following values in checkable:
    1. Blank u2013 no check table
    2. A table name such T005, it is the check table name
    3. * - a star
    I do not know what is the meaning of a *.
    Appreciate your answer?

    Hello,
    Did you check the "Supplementary Documentation" of the Data Element CHECKTABLE. It states & i quote:
    The entry *  indicates that the domain has a value table but no foreign key has been maintained for the field.
    Hope this clarifies your doubt.

  • What does wireless mean for a printer?

    I have an HP photosmart printer (sorry but I can't think of the model and I am not home) that has wireless capabilities.  What does this mean?  Does this mean that i can access the printer from my notebook, pda and other wireless devices through the wifi device that is in the printer or does it mean that only one computer can connect to the printer by wifi?

    It means really two things:
    1. You can connect up to 5 computers wirelessly with the printer (called ad-hoc networking).  Now, when those computers are connected with the printer they cannot be connected to any other wireless device (like a wireless router).
    2. The preferred method - connect your printer to a wireless router.  All computers connected (wired or wireless) to that router can use both the print and scan function (if applicable) of the device.
    Say thanks by clicking "Kudos" "thumbs up" in the post that helped you.
    I am employed by HP

  • Roaming - what does it mean for a Tracfone phone?

    I have a Tracfone LG Optimus Dynamic phone that runs on the Verizon network. I read that these phones do not 'roam'. What exactly does roaming mean?
    Thank you.

        paularose, you're in good wireless hands with us. Your device does have the capability of roaming. Roaming is when your device can make/receive calls in situations when you are temporarily outside of your coverage area. We recommend that you dial *228 and choose option 2 to update the roaming capabilities on your device.

  • Now that CS5 has arrived, what does it mean for your system setup?

    Apart from nice added features, improved stability and increased speed, there are two major factors that impact on your system setup:
    1. 64 bit
    2. Mercury Playback Engine
    64 Bit only
    This means a couple of things:
    You need a 64 bit OS, you need 64 bit plug-ins and you can use much more memory than the 4 GB limitation that applied to 32 bit OS'es (with effective memory in the 2 - 3 GB range, depending on the Boot.ini switch).
    In practice, to benefit from the move from 32 bit to 64 bit, the recommended memory needs to be around 8 or 12 GB, depending on your mobo and chipset and the number of DIMM slots available. With current prices (May 2010) it is not yet economical to opt for 4 GB sticks.
    If you have a dual socket board with 12 or more DIMM slots, 24 GB is optimal.
    Mercury Playback Engine
    This is where it gets interesting.
    In the past, up to and including CS4 4.2.1, performance was largely impacted by:
    1. CPU
    2. Memory
    3. Disk setup
    4. OS & Tuning
    5. ...
    and finally by the video card. It did not really matter what video card you had installed. There never was any discernable performance gain from expensive video cards.
    The tables have turned.
    With CS5, installing a CUDA enabled video card has a large impact on performance and lessens the burden on the CPU. The GPU does a lot of the work.
    However, since the CPU gets a lot more breathing space, the CPU will no longer be the primary bottelneck, as was often the case in the past.  And since all DIMM slots in the average machine will be occupied, it is a costly exercise to exchange the DIMM sticks with larger capacity ones. People who have only 3 slots in use on a X58 motherboard can directly benefit from adding three more sticks, but this does not happen very often.
    So with the CPU running with a relatively low load and memory more or less a given, the only thing that may be a bottleneck to be improved upon is the disk setup. This can be seen easily by scrubbing fast through the time line with the popular AVCHD material. Due to the MPEG nature, while scrubbing one needs to look backwards and forwards to create the image under the CTI and that means a lot of disk activity. CPU is not a bottleneck, memory is not a bottleneck and the GPU is not the bottleneck, it is the disk setup.
    Do not be fooled by the claims that SATA2 or SATA3 have enough bandwidth to support the data rate of AVCHD or other MPEG streams. Tests have shown that significant performance gains can be achieved by using a large number of disks, preferably in a raid. This is especially true when one has multiple tracks.
    SSD's are not yet an economical alternative for conventional hard disks, with prices that are a factor 30 - 50 higher per gigabyte than conventional disks.
    Conclusion
    To fully benefit from the performance gains that CS5 allows, it may be that using a MPE supported card will lead to the disk setup being the new bottleneck. Be aware of that fact.

    at this point we are still trying to figure out whats up.
    bear in mind DV VS AVCHD or Red is a completely different animal. there is a lot to process on encoding vs DV
    we think the processors and HDDs are sitting there waiting on CS5
    even with Dual Xeon 2.8GHz 12 cores its no faster than the 980x niether are CPU pegging, HDD pegging or ram..
    interesting is the Dual Xeons will use about 10G (with 24G installed) ram vs the 980x using 6 (with 12 installed)
    dual Xeons have dual memoery pipe lines 1 for each cpu so we think thats where its coming from
    but we are still scratching our heads with a good deal of what we are finding in these benchmarks.
    most is pointing to CS5 coding.
    i am sure Eric will poke his head in here...

  • What does it mean when I get this message: "an error occurred while processing this directive"

    www.sprint.com main page loads with this error message all over the page. If I click on business at top of site and then back to personal all loads correctly. What do I have to do to have it load the first time?

    It sounds like an error on the server: Firefox may be sending something unexpected, inconsistent, or incomplete that is causing the failure. But since they give so little information, that's just a guess.
    When you have a problem with one particular site, a good "first thing to try" is clearing your Firefox cache and deleting your saved cookies for the site.
    (1) Bypass Firefox's Cache
    Use Ctrl+Shift+r to reload the page fresh from the server.
    Alternately, you also can clear Firefox's cache completely using:
    "3-bar" menu button (or Tools menu) > Options > Advanced
    On the Network mini-tab > Cached Web Content : "Clear Now"
    If you have a large hard drive, this might take a few minutes.
    (2) Remove the site's cookies (save any pending work first). While viewing a page on the site, try either:
    * right-click and choose View Page Info > Security > "View Cookies"
    * (menu bar) Tools > Page Info > Security > "View Cookies"
    In the dialog that opens, you can remove the site's cookies individually.
    Then try reloading the page. Does that help?

  • What does it mean when it says "This item is being modified. Please try again later."?

  • TWC/Comcast testing broadband cap, what does it mean for Apple TV?

    Read an interesting article in Newsweek about some cable companies (currently testing) limiting broadband downloads and charging extra when the user exceeds the cap.
    Has anyone thought what this could do to users of Apple TV and other download services?
    Movies that start out as $2.99, $3.99, $4.99 could end of costing much more depending on the cap and extra charges.
    It's just another way for them to generate revenue and curb usage of "other"(insert Apple TV) alternatives to their On-Demand services.
    Crazy stuff.

    I have a feeling this is certainly on of the primary reasons cable providers like Time Warner and Comcast are fiddling with this.
    They say it's because of maxing out on bandwidth, but they keep selling packages for greater bandwidths! How can you get a 12Mbps downstream speed and pay for it but then have them not guarentee it?
    It seems to me that if bandwidth was that limited it would be throttled rather than placing a fee over top of high downstream usage. But then again, all they care about is making money and protecting their empires. Eventually this will end up in anti-trust court if they believe they can continue to play this way or until a really solid and widespread alternative competitor pops up like Verizon FIOS which isn't available in many areas yet.

  • What does "Backups" mean in the "About this Mac" storage graphic?

    I just migrated the contents of one Mac to a new MacBook Air and discovered something I had never seen before.  I had 37MB of storage taken up with "Backups."  What is that?  What is the best way to reduce or manage it?
    One other question, while I am at it.  What is included in the category of "Other?"

    OS X: What is "other" space in About This Mac? - Apple Support
    About Time Machine local snapshots - Apple Support
    The local snapshots should take care of themselves if you have a backup drive in place and Time Machine activated. 

  • What does it mean when I get this message:  "Battery is critically low"

    I am suddenly getting a message "the battery is critically low" - am I in danger here?????

    You're in danger of the Mac shutting down, that's all. Recharge your battery when you get a chance.
    If you believe the message is spurious an SMC reset is justified. Read all the steps:
    Before Resetting the SMC
    Try each of the following steps in this order before you reset the SMC. Test the issue after completing each troubleshooting step to determine if the issue still occurs.
    Press Command + Option + Escape to force quit any application that is not responding.
    Put your Mac to sleep by choosing the Apple () menu from the upper-left menu bar and then choosing Sleep. Wake the computer after it has gone to sleep.
    Restart your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Restart.
    Shut down your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Shut Down.
    Resetting the SMC on Mac portables with a battery you can remove
    Shut down the computer.
    Disconnect the MagSafe power adapter from the computer, if it's connected.
    Remove the battery (to remove the battery - click here: MacBook or MacBook Pro).
    Press and hold the power button for 5 seconds.
    Release the power button.
    Reconnect the battery and MagSafe power adapter.
    Press the power button to turn on the computer.
    Still having problems? Replace steps 6 and 7 with the following:
    Reconnect just the MagSafe power adapter.
    Press the power button to turn on the computer,
    Then reconnect the battery.

  • Access log - what does ETIME mean for searches?

    I am running Directory server 5.1 sp4. We recently had an issue where a search was initiated by a webserver with a bad network card. The symptom was intermittent 'ABANDON' entries in the log. However, when the ABANDON is in the log, the ETIME of the search is high - 10 seconds or so. Normal response time for the same search is 0. It appears that the ETIME of the search includes time spent trying to send the results back (unsuccessfully) to the requester. Is this a valid theory?
    Here is a sample search from the log...
    [20/Mar/2009:11:32:47 -0400] conn=23294 op=1247 SRCH base="cn=xxx,o=yyy" scope=2 filter="(|(objectClass=zzz)(objectClass=aaa))" attrs="bbb"
    [20/Mar/2009:11:32:57 -0400] conn=23294 op=1247 RESULT err=0 tag=101 nentries=438 etime=10
    [20/Mar/2009:11:33:06 -0400] conn=23294 op=1248 ABANDON targetop=NOTFOUND msgid=1248

    Yes, the etime will also include the time it takes to send that data back to the client. This is also considered part of the LDAP operation and so bad network performance can also cause higher etimes.

  • IMac 20", 128 meg of 256 meg, what does it mean for performance?

    I was always a firm believer that generally vram didn't play a huge part in performance, other than it's clock rate obviously, it just allowed you to run higher resolution. I've heard some claim the 256 meg version has a noticeable speed improvement.
    Questions are: What is the clock rate of the processor and memory in each version? I'm mainly curious if they are the same, but am also curious if it's the same clock rate as in Intel laptops. I know the Macbook pro is tuned down for battery life from the factory, and have heard rumors the iMac is also.
    Other question is, is there a performance difference in gaming at native resolution and lower for the 20" iMac? And if so, how much are we talking? 52fps as opposed to 50fps, or something more substantial?

    I have the 256MB vram version and I can tell you that the stock speed of the x1600 is 400mhz core/400 mhz memory. I do not know what the stock speed is of the 128 MB version. The 17", the speeds are closer to 300/300.
