Collection to contain the object type? OR typical hash in java?

Hi people,
I used to work in perl and use hashes a lot (a typical perl hash is String = > string). Well now, I am doing something a bit dirty - I need something that does what the class that I put in place down, it doesn't... Y at - it such an object which wouldn't bother me that the keys and values are not unique (can be same values with the keys and values). What I must apply myself, or is there something that does this...
No collection seems to fit in this...


public class CantFindYouInJava {}
private String [] listOfKeys;
private String [] listOfValues.
' Public Sub put (String key, String value) {}
where int = listOfkeys.length + 1;
listOfKeys [where] = key;
listOfValues [where] = value;
}
..
}

It really depends on what the relationship between a key and its associated value, and the kind of performance you expect to recover from.

Kayaman suggestion is probably the best if the relationship of key / value is 1-to-many; You can also write your own map> class. If it's really one-to-many, and you need good performance in both directions, you may need to wrap two MultiMaps - one go of the key values and a second to go in the other direction. Don't know what you'd call it however.

    The same basic problem as in your previous thread. Confusion between creating an object from a collection/table of this object.

    Here's a basic example:

    SQL> create or replace type TScalar is object(
      2          id      integer,
      3          name    varchar2(10)
      4  );
      5  /
    
    Type created.
    
    SQL>
    SQL> create or replace type TArray is table of TScalar;
      2  /
    
    Type created.
    
    SQL>
    SQL> --// creating a scalar
    SQL> select TScalar( 1, 'John' ) as OBJ from dual;
    
    OBJ(ID, NAME)
    --------------------
    TSCALAR(1, 'John')
    
    SQL>
    SQL> --// creating an array/collection
    SQL> select
      2          TArray(
      3                  TScalar( 1, 'John' ),
      4                  TScalar( 2, 'Tom' )
      5          )                               as ARRAY
      6  from       dual;
    
    ARRAY(ID, NAME)
    --------------------------------------------------
    TARRAY(TSCALAR(1, 'John'), TSCALAR(2, 'Tom'))
    
    SQL> 
    

    So in your function, you will need to place objects in the collection.

    return(
        Rt_Type_Var(                      --// instantiate the collection
               Type_Rt ('STRT',var1_nri ,liq_Rt,'Stle' ,null)  --// place an object into the collection
        )
    );
    

    And use appropriate type names and the object. Poorly chosen and non standard naming conventions just add to the confusion.

  • How to fill the value in the nested table by using the object type


    Hi gurus

    I created an object type and able to fill the values in it, now I want to create a nested table type of this object and fill it but looks like I'm doing something wrong, see my code below.

    Code example

    Concerning

    Hi user,

    Here is another method that you can try-

    CREATE OR REPLACE

    ABC of the PROCEDURE

    IS

    v_print countries_t: = countries_t (countries_o('01','A',11));

    BEGIN

    DBMS_OUTPUT. Put_line (v_print (1).) COUNTRY_ID | v_print (1). COUNTRY_NAME | v_print (1). REGION_ID); -you're accessinf the first element of the nested table, which in turn points to the object.

    END;

    In the sections of the declaration you have assigned values to the nested table.

  • Resize the artboard to contain the object in Illustrator CC 2015

    In the past I could easily resize my work plan to fit the dimensions of my art simply by double-clicking the object desired by using the tool of work plan. After the upgrade to 2015 CC, I was sad to find that this feature has been removed. Anyone know if there is a workaround or how I could easily do this without manually adjust the work plan? Like so many things, I notice in CC 2015, this change of bugs completely.

    Thank you!

    Jessica, other,

    Just to make sure, what happens if you disable the GPU performance by clicking on the icon of the rocket in the App bar and deselect the box Performance GPU?

  • Create the object type with a member function that returns an array of the object type

    Hello

    Is possible to compile code like this in Oracle SQL?

    CREATE OR REPLACE TYPE type_obj IS OBJECT (
      MEMBER FUNCTION f RETURN table_obj
    );
    
    CREATE OR REPLACE TYPE table_obj AS TABLE OF type_obj;
    
    

    In Java, it would be possible.

    Thanks in advance

    Circular dependencies must be resolved by means of REF pointers and incomplete type definition.

    See: Oracle objects management

    CREATE or REPLACE TYPE type_obj;

    /

    CREATE or REPLACE TYPE table_obj AS TABLE OF ref type_obj;

    /

    CREATE or REPLACE TYPE type_obj () IS OBJECT

    fake number

    Table_obj RETURN of the FUNCTION MEMBER f

    );

    /

    Now, it must implement the body of type.

    Note that a table of the REFs is not very useful in the plain of PL/SQL, the underlying data must be stored in a nested table if you want to use.

  • Test a SP with the object type

    Hi, I have a MS in which I created an object of TYPE and through multiple values as param.

    TYPE typ_clint_id_rec AS OBJECT
    ( CLIENT_ID VARCHAR2(20);
    
    TYPE typ_clinet_id_tab AS TABLE OF  typ_clint_id_rec;
    SP signature
    PROCEDURE test( in_username IN char
                              in_client_name IN   typ_clinet_id_tab,
                              in_out_cur IN OUT out_cursor)
    ;
    Now, I'm testing the PC like this:
    declare
    
    ref_cursor sys_refcursor;
    in_client_name typ_clinet_id_tab := typ_clinet_id_tab ();
    begin
    
    in_client_name := typ_clinet_id_tab ('AAA','BBB');
    test(in_username=> 'test' , in_client_name=>in_client_name ,in_out_cur => ref_cursor);
    end;
    But it gives wrong number or types of arguments in the call to typ_clinet_id_tab?

    Can someone tell me what is wrong with that?

    Aashish

    Each attribute of your object to table table must consist of the typ_clint_id_rec object.

    So the data must be wrapped as follows;

    typ_clinet_id_tab (typ_clint_id_rec'AAA'),typ_clint_id_rec('BBB'));
    
  • Function returning the tree used with the object type

    Hi guys!

    I'm fighting for some time now of a function that should return the tree structure of the employees. Let me clarify...
    I have a table say Manager and employees (two columns for an example)
    MANAGER_ID
    EMPLOYEE_ID

    Example:

    MAN_ID - 1; EMPLOYE_ID - 2;
    MAN_ID - 2; EMPLOYE_ID - 3;
    MAN_ID - 2; EMPLOYE_ID - 4;
    MAN_ID - 4; EMPLOYE_ID - 5

    The purpose of my function is back for a specified MAN_ID everyone in the tree...

    Example:

    RETURN_TREE (1) return {2,3,4,5};
    RETURN_TREE (2) returns {3,4,5};
    RETURN_TREE (4) returns {5};

    How to get there?

    With respect,

    PsmakR

    And use BULK COLLECT or the COLLECT function to build the collection:

    create type emp_table as table of number(6);
    /
    
    DECLARE
     v_emp_list emp_table;
    BEGIN
     select cast(collect(employee_id) as emp_table)
     into v_emp_list
     from employees
     connect by prior employee_id = manager_id
     start with manager_id = :p_man_id
    
     -- or
     /*
     select employee_id
     bulk collect into v_emp_list
     from employees
     connect by prior employee_id = manager_id
     start with manager_id = :p_man_id
     */
    END;
    /
    
  • Background image, change of color of the object/type

    I retouched an image that I then placed in CC Id as part of the background. Unfortunately, the type and the items that were on top of this image are corrupted. The text looks like it's more "BOLD" and transparent colored box of 50% is much darker where they overlap the picture. This problem appears if I make a PDF print. Anyone know what is happening here, and how I can solve it?  Thanks in advance!

    In InDesign, choose the [Black] swatch is automatically set to overprinting. It is defined in the preferences > appearance of black. Uncheck the option or create your own black shade to K100.

  • BEGINNING about the object type indexes per table

    Hi all

    I've been tyring just what follows.

    declare
    type ty_tab is table of the directory index ty_test;

    my_tab ty_tab;

    Start
    my_tab (1):=ty_test(1111,ty_info('ashok',1000));
    my_tab (2):=ty_test(2222,ty_info('Rashmi',2000));
    my_tab (3):=ty_test(3333,ty_info('unknown',3000));

    for me in my_tab.first... loop of my_tab. Last

    dbms_output.put_line (my_tab (i) .empno |) » '|| my_tab (i) .info);

    end loop;

    end;

    /

    When running the script, I get the following error.
    ORA-06550: line 13, column 25:
    PLS-00306: wrong number or types of arguments in the call to ' |'
    ORA-06550: line 13, column 4:
    PL/SQL: Statement ignored

    Can anyone suggest?


    Thanx

    the attributes of the type ty_info assuming that are name and val:

    dbms_output.put_line(my_tab(i).empno||' '||my_tab(i).info.name||' '||my_tab(i).info.val);
    

    SY.

  • execution of actions on a selection based on the object type

    Hello.

    I am trying to write an AppleScript that considers the current selection, then redefines the scaling of all lines of that selection to 100%, and then sets the absolute horizontal scale of the remaining elements of the selection to 100%.

    My attempts so far are:

    say application «Adobe InDesign CS3»

    put Original_Selection to selection

    put to each graphic line of Original_Selection Lines_Selection -this part is not working

    put transform reference point of window layout 1 to anchor Center

    Choose Lines_Selection

    redefine the scaling to the selection {1.0 , 1.0}

    Choose Original_Selection - but it must be ' Original_Selection less Lines_Selection ' somehow

    put horizontal scale absolute at 100

    end say

    None of this really works as I expect, but I can't find out the required syntaxes. Anyone know where I am going wrong?

    Thank you.

    Try this:

    say application «Adobe InDesign CS3»

    the value transform reference point of window layout 1 of anchorage Center

    redefine the scaling of (each point of selection which class is the line graph) to {1.0, 1.0}

    the horizontal scale absolute value of (each element of selection whose class is not graphic line) to 100

    end say
