How do I make a function final?

Hi all,
This question has probably been asked before but I couldn't find any postings on it. Is it possible to prevent a function from being overridden in subclasses as per final methods in Java?
Cheers,
Kevin

That's a shame. I've raised a JIRA for it because I think it is something that should be added to the language. For anyone reading this thread who would also like to see the 'final' modifier for functions, please add your vote here:

    How do I make titles in Final Cut Express HD?

    Select the kind of title you want, drag it to the Viewer.  Click the Controls tab in the Viewer.  Enter your titles, tweak your settings (color, font, etc).  Then move the clip to your sequence.   In general, Boris Title 3D and Title Crawl work best.
    If you want the titles to appear over video, place the title clip(s) on a track that is higher than your video.

  • How do I make one function trigger another one.

         The best way I can describe what I am looking for is to say that I am working on a project that once you click the button at the begining it plays a movieclip and has a few different scenes throughout the project. So what I need is when you click the button the first mc plays and when the first mc is done it triggers a second one to play without needing to hit a button. I hope this is just something simple I am missing.
    Thanks!

    Putting all together I now came up with two issues. The original one with the trigger and now the button decided to stop working after it worked fine. 
       public class maythe4thfinal extends MovieClip
            public function maythe4thfinal()
                opening.buttonMode = true;
                opening.addEventListener(MouseEvent.CLICK, moveIt);
            private function moveIt(evt:MouseEvent):void
                opening.visible = false;
                this.swbg.gotoAndPlay(2);
                this.farfar.gotoAndPlay(2);
                this.swbg.addEventListener(Event.ENTER_FRAME, scroller2);
            private function scroller2(evt:Event):void
                if (this.farfar.currentFrame == 55)
                    this.scroller2.gotoAndPlay(2);

  • How can I make this function thread safe?

    delete this post please. accidental.

    is your function calling itself in its execution? that's why
    your array
    is being re-created with each call...
    sounds like you should be using a conditional loop... maybe
    something like:
    <cfset var functionItemID = arguments.itemID />
    <cfset var bcArray = arraynew(1)>
    <cfloop
    condition="application.tags.hasParent(functionItemID,arguments.itemDeleted,arguments.itemS tate)
    is true">
    <cfset
    arrayAppend(bcArray,application.tags.getItemField(functionItemID,"item_id"))
    />
    <cfset functionItemID =
    application.tags.getParent(functionItemID,arguments.itemDeleted,arguments.itemState)
    />
    </cfloop>
    <cfreturn bcArray />

  • PL/SQL: How to make a function accessible to all users?

    How can I make a function accessible to all users?
    I have written a stored function called GET_NET_BALANCE.
    I can run it but my users cannot.
    I have tried the following, but my users still cannot
    run the function:
    GRANT EXECUTE ON GET_NET_BALANCE TO PUBLIC;
    Thanks, Eileen

    Hi,
    You can try creating a public synonym on the function so that it is accessible to all.
    To get greater response.. please post your question at

  • How do I make a pic in final cut Pro stop  flickering?

    how do I make a pic in final cut Pro stop  flickering?

    Question: how do I make a pic in final cut Pro stop  flickering?
    Answer: It depends on what is causing the flickering.  It could be due to the pixel dimensions being too large for the Sequence settings in FCP.  It could be due to thin horizontal lines in the image.  It could be due to areas of the image in high contrast with each other.   Or it could be due to a combination of several factors.
    If the image is too large, reduce the pixel dimensions to a more reasonable size.
    If it's due to thin horizontal lines, deinterlace the image, or slightly blur the lines in Photoshop.
    If it's due to areas of high contrrast, reduce the contrast of those areas in Photoshop.
    In FCP you can also try applying the Flicker filter to the image in the Timeline and/or a Gaussian blur filter with a setting of around 0.2 or 0.3

  • How do I make purchased apps, like numbers,keynote,pages,office pro, show up in "open in" function for email attachments?

    How do I make my purchased apps such as, Pages, Numbers, Keynote, Office Pro, available for opening attached documents in email in the"open in" function?

    Thanks for your reply.
    Anyway, here is what I am trying to do:
    It is for a context sensitive display. I am going to sprinkle command links throughout the system and each link will query the database for a specific string and bring out the results in a pop up window.
    I have a backing bean that does the query and a JSF form (that I am trying to pop up) that uses this bean to display the results.

  • How can i make a pl/sql function for BLOB datatype

    hi..anyone here who is very familiar about BLOB datatype. i have a COLUMN_ID, COLUMN_A in a certain TABLE_1. COLUMN_A is blob datatype that contains almost 250,000rows
    SQL>select column_A from table_1 where column_id=1234567
    column_A
    00000001000000010000000606D4E833074B69EC06D4E91F074CO18406D50C58074C031E
    how can i make a user-defined function to compute and convert this blob datatype into decimal length value. this hex value are points in the map.. the function must contain
    1.get the length of a blob then
    2.convert blob to variable hexadecimal characters by parsing it into 8
    3.to_number function or other function used to convert haxadecimal characters to decimal numbers
    4.phythagorean formula to compute length between two points. this is the formula i think LENGTH =
    SQRT(power((coordinate_x-prev_coordinate_x),2)+power((coordinate_y-prev_y),2));
    after this when i type this
    SQL>select user_function(column_A) from table_1 where column_id=1234567
    user_functions(column_A)
    --output length will be in decimal value already
    the function will goes like this
    step1 is to get the blob length
    00000001000000010000000606D4E833074B69EC06D4E91F074CO18406D50C58074C031E
    step2 is parsing of data by eights
    00000001 =>1
    00000001 =>1
    00000006 =>6 (number of coordinates)
    06D4E833 => X1
    074B69EC => Y1
    06D4E91F => X2
    074CO184 => Y2
    06D50C58 => X3
    074C031E => Y3
    step3 to_number function used to convert hex char to decimal
    step4 compute by phytagorean (NOTE ! when computing length the third parsed eight will tell how many coordinates are there..the number of coordinates is ranging from 2 up to E..above example shows 6 coordinates so it means
    LENGTH1 =
    SQRT(power((X2-X1),2)+power((Y2-Y1),2));
    LENGTH2=
    SQRT(power((X3-X2),2)+power((Y3-Y2),2));
    TOTAL LENGTH=LENGTH1 + LENGTH2
    thanks

    its my first time to use that.There's got to be a first tiem for anything. Be brave.
    btw if theres more easy suggestion pls feel free..Well of course the easiest solution would be if the calling program passed in the parameters as separate arguments instead of glomming them together in a string that has to be parsed. This sort of kluj really ought not to have survived into C21.

  • How to make this function module as RFC to get data from different system?

    Hi
    I am trying to use following function module . This function module is used to copy data from one cube to another cube within same system however I need a this should happen across two different system. How can I use this function module to make it remote call to different system and do the same function what it is doing ?
    Name of function module -
    RSDRT_INFOCUBE_DATA_COPY
    Any help would be really helpful
    AG

    HI,
      let us say you want to copy the data of a cube in system A to a cube in system B .
      1) create a RFC function module in system B (in this function module  call the function module RSDRI_CUBE_WRITE_PACKAGE to update the data), this RFC function module should have same parametersa as RSDRI_CUBE_WRITE_PACKAGE .
    2) write a program in system A .. read the data from the infocube using the function module RSDRI_INFOPROV_READ and call the RFC function module in system B that you have created..
    for the details of the parameters to pass to these two function modules use the RSDRT_INFOCUBE_DATA_COPY and get the required code
    Thanks
