Using variable names for object names

Is there any way you can use a String variable to name an object? I.e., something like:
String name = "objectName";
\\ create an Image object named objectName
Image (name.valueOf()) = new Image();
This code obviously does not work, but I'm working on a map applet which uses a map composed of thousands of tiles, and then shows only a portion of the map by drawing the appropriate tiles into the window using the x/y coordinates and a nested for loop to determine which tiles to draw. However, unless I want to manually declare and then call each of these Image objects, I need to have a way to have the actual name of each image object be a reference to a variable, which I will then initalize according to the name of the tile I'm using. Does that make sense at all? Anyway, I was just wondering if anyone knows of any way to do this. Thanks.

Typically this is done using a Collection, for example:
Image[] img = new Image[100];
for (int i=0; i<img.length;i++)
  img[i] = new Image();... Sort of thing.

    What is the name of the DB Link and the name of the object you are selecting
    from?
    I find it easier to create a view on the remote object then use that in selects.
    e.g,
    Link Name = MyLink
    Object_name = Addr_Loc
    create or replace VIEW Rem_Addr_Loc AS
    select * from addr_loc@mylink;
    In the code I then use the view
    begin
      for C_Rec in (select * from Rem_Addr_loc)
      loop
         dbms_output.put_line('Rec: '|| C_Rec.Col1);
      end loop;
    end;                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   

  • Using variable name for Netstream Publish() (actionscript)

    Relatively new to Actionscript.  In the netstream publish() or play() methods, can I pass variable names to the methods instead of hard-coding the stream name?
    Example:
    private function publishLiveStream():void
                ns = new NetStream(nc);
                ns.addEventListener(NetStatusEvent.NET_STATUS, netStatusHandler);
                ns.client = this;
              // blah blah other stuff...
               ns.publish("thefilename", "record");
    I want to replace "thefilename" with a value passed from an input box or use dynamic naming (i.e. current date & time).

    you can use in procedure using sunopisis technology
    OdiExportMaster "-TODIR=/temp/" "-ZIPFILE_NAME=export.zip" "-XML_CHARSET=ISO-8859-1" "-JAVA_CHARSET=ISO8859_1" "-EXPORT_VERSIONS=YES"
    or you can use (unix System)

  • How do i filter the records in analytic view by using variable/parameter for a time range

    i have a analytic view which has a output column as date type. i want the user who use this view have the control to decided the output records based on a time range (from x to y).
    i tried to create 2 variables, 1 for start_time, 1 for end_time. Ideally, i should have a expression for filtering data like this:
    $$start_time <= date_column <= $$end_time
    However, the variable windows doesn't seem to be feasible for the expression as above.
    Does anyone has the same problem and get it solved?
    Thanks!

    just figured out by my own. So the answer is using "variable" with "range" option.
    Making a variable, then set the "selection type" to "range".
    When preview the data, the variable input window pops up with operator on default "equal", use dropdown list to swtich it to "between", then you can enter the start_time and end_time as a range filter.

  • FTPs connection error:When using Variable substitution for Directory path

    Hi
    I am transferring data from BI to xml file via PI: Here a Client proxy from BI sends the data to PI and the PI FTPs the XML file to a remote location. For FTP I am using FTPs SSL connection.
    It was working fine untill I used Variable susbstitution to determine Directory path dynamically. I am using this because different xml files are intended to goto the different locations.
    I did the variable substitution like this:
    Target Message Structure:
    ---> Target Directory: %var1%
    <?xml version="1.0" encoding="UTF-8" ?>
    <MT_BI_EXTRACT_FILE>
      <Header>
         <Directory>/Customer</Directory>
    </Header>
    <Detail>
    </Detail>
       </MT_BI_EXTRACT_FILE>
    And in the variable substitution I am doing it this way
    payload:MT_BI_EXTRACT_FILE,1,Header,1,Directory,1
    And the error I am getting is:
    Attempt to process file failed with Error when getting an FTP connection from connection pool: com.sap.aii.af.service.util.concurrent.ResourcePoolException: Unable to create new pooled resource: iaik.security.ssl.SSLException: Peer sent alert: Alert Fatal: handshake failure

    Does anybody have some Idea of this ??
    Regards

    Hi,
    I guess the problem is not with Variable Substitution..
    Error when getting an FTP connection from connection pool:
    So its a connection problem..
    Also check the option Disable Security check and try again...
    Try to check again if the interface is executing properly without Variable substitution and let us know..

  • Using variable names in the jakarta img taglib

    I am using the jakarta image taglib for manipulating images, it is working fine with static names like this
    <img:image src="xyz.jpg"..etc
    but once I replaced the image name with this scriplet
    <img:image src="<%= book.img %>
    I got noting although I am sure that my scriplet has value but the image didn't show up, any idea
    thank you

    the problem was solved I've used the EL notation instead of scriplet and it worked

  • [SOLVED] problem using variable in "for do" loop statement

    As 'm fairly new to scripting in linux there are still many things I don't know about the regular syntax. So I've made a script where in a variable $nb I retain the number of lines from the result of a series of commands. I have to use a variable as the number of lines from the output is not the same all the time.
    To finish my script I need to use a for loop something like this
    for i in {1..$nb}
    do
    echo "bla bla bla $i"
    done
    the thing is if $nb, for example, has the value 29 it outputs
    bla bla bla {1..29}
    without doing any loop.
    So how can I use a variable, to define the edge of an interval in a for statement ?
    Last edited by I'mGeorge (2011-06-18 16:19:16)

    The sanctioned method in Bash is using a C style for loop:
    for ((i=0; i<nb;i++)); do
    done
    Because brace expansion is performed before parameter expansion, a range like {1..$nb} will fail.

  • Using variables as table names. Ideas for alternative designs

    Hi,
    I am designing an application which uses synonyms to pull information from 'client' DBs via DB Links. The synonyms are created with a DB_ID in the name (example: CUSTOMER_100, CUSTOMER_200... where 100 and 200 are DB IDs from 2 separate client DBs.
    I have a procedure which selects data from the synonym based on what DB_ID is passed to the procedure. I want to be able to run this one procedure for any DB_ID that is entered. I am now aware I cannot use variable names for table names and using EXECUTE IMMEDIATE doesnt seem to fit for what I am trying to do.
    Does anybody have any suggestions or re-design options I could use to achieve this generic procedure that will select from a certain synonym based on the DB info input parameters? Thanks.

    Hi
    rules engine style with table that holds the logic or code SQL directly in the procedure and IF THEN ELSE with db_id. Latter is better because SQL is native and objects are checked every time procedure is compiled.

  • Variable subsitution for target file names

    Hi All,
    I am using variable subsitution for dynamic file names. I am using the multimapping for multiple files in the target.So i coluld not able to use the dynamic configuration for file names. Now i want to replace all the spaces in the filename to underscore.
    For example
    My payload filed value "file name in the target file".
    Now my filename  "file_name_in_the_target_file".
    How to achieve this using Variable subsitution.
    Regards,

    Use replaceString Function.
    file name
    Constant (" ")               --> replaceString -------> TargetField
    Constant ("_")

  • Reciever File Adapter - Temp File Name Scheme using Variable Substitution

    How can I create a temporary file that uses variable substitution? 
    We are having a problem with files merging when we write files using the "Use Temporary File" setting on the FIle Adapter.  So two independent files are merging into a single file.  We are not using the "Append" setting.
    We would like to use a Temp File Name Scheme that would append the message id onto the temporary file name. 
    Using variable substitution we created a msgid variable.  When added to the temporary file name using %msgid% the temporary file name is created with %msgid% in the name instead of the actual message id.  We put the variable into the "File Name Scheme" as well and the end completed file used the message id in the name.
    Any Ideas?
    Thanks,
    Matt

    HI Matthew,
    Why are you adding the message id into the temporary file??
    I understand that you want the output of the filename to contain message id .. and hence you are using variable substitution for the same.
    Temporary file name will anyways get overwritten by the actual file name (here the actual filename will be using variable substituion).
    So i suggest to achieve your scenario you can add any name in the temporary file and maintain the desired filename you require as output in the variable subsititution.
    Temporary File Name option actually acts as a lock - unlock mechanism from PI side while the file is getting written to the file server so that while PI is writting the file no third party application batch program picks it up.
    I hope this helps.
    Cheers
