Statistical distributions - get and setter methods

Hi,
I found the Weibull and Cauchy class here:
http://commons.apache.org/math/api-1.1/org/apache/commons/math/distribution/CauchyDistributionImpl.html
however these distributions do not seem to have methods to pick a random number within the distribution.
Does anyone have any advise on how to do that?
Thanks,
Lene

Ok, I don't see a getNextValue or getNextDouble.
Did you mean inverseCumulativeProbability?
I guess I could create a random P and then look up the x at that p, to get a random value from the distribution.
Thanks,
Lene

  • Code for replacing 'get' and 'set' method

    Hi,
    I was a struts programmer but now i am a jsf programmer :-)
    I was able to do the following with struts but no with jsf...
    The following code in struts allowed me to have no 'get' and 'set' method in the javabean for a property (for example, the property 'name'):
    ValueStack valueStack =ActionContext.getContext().getValueStack();
    valueStack.set("name", "John");
    ActionContext.getContext().setValueStack(valueStack);In the jsp, using the corresponding label to retrieve the 'name' property, returned value 'John'.
    Is there something equivalent in jsf?

    Hi, see on here.There are solutions for JSF, JBoss Seam: [Solutions for Java, JSF, JBoss Seam and Flex|http://flextrick.blogspot.com/]

  • Why do we need get and set methods?

    It is considered good design practice to keep all class data private and
    provide get and set methods for accessing the data in a controlled
    manner.
    So, instead of directly accessing the class data, you use getter and setters.
    I do not really feel the need to use get and set methods.
    How does that achieve encapsulation when ultimately the class data is being exposed?

    A couple of reasons why to use get and set:
    1. For example you can set an int value for month, if a user sets this to somting
    higher than 12 (or 11 if it's zero based) you want to handle that by either
    throwing an exception or adding a year for every time it can be devided by 12.
    If you dont do it in set you'll have a whole bunch of methods that might need to
    correct the value before retreiving the eventual date.
    2. If for some reason you have security set up for certain values you can
    implement this in the get method. When this is done somewhere else you have
    a whole bunch of methods retreiving the info in other classes that need to check
    first. (a canGet method could allso be used). Another good reason to use get
    is when the information needs to be converted depending on the consumer
    calling the get method.
    3. If any logic in 1 or 2 changes you'll have a bunch of code to change.
    If you feel there is no need to implement any security, error handling (on
    compiling because get and set might throw something) or validation when
    setting/getting these values there is still the argument of readabillity.
    Eclipse has a feature that will generate getters and setters for you so it's not
    like there is a lot of extra typing involved.
    Got interupted whyle typig so sorry to repeat any answer given before.

  • Usage of AQ$_JMS_MESSAGE getter and setter methods in PL/SQL functions

    Hi all,
    while setting up a transformation from a AQ$_JMS_TEXT_MESSAGE to a user-defined type "msgtype" ( subject varchar2, text clob ) I tried to use the get_text() method within the transformation function but got a
    ORA-25229: error on transformation of message msgid: ...
    ORA-30625: method dispatch on NULL SELF argument is disallowedAccessing the CLOB part of the jms_text_message directly did not work. But within an anonymous PL/SQL procedure, get_text() works fine.
    It has to be in a function to work as a transformation, but how can I do this?
    Here's my current code:
    CREATE OR REPLACE FUNCTION jms2msg_t(in_jms SYS.AQ$_JMS_TEXT_MESSAGE)
    RETURN TxtMsgType AS
      new_msg  TxtMsgType;
      v_oldmsg SYS.AQ$_JMS_TEXT_MESSAGE;
      v_clob   CLOB := EMPTY_CLOB;
    BEGIN
      dbms_lob.createTemporary( v_clob, true );
      dbms_lob.open( v_clob, DBMS_LOB.LOB_READWRITE );
      v_oldmsg.get_text( v_clob ); -- ora-30625 happens here ----------------
      new_msg := TxtMsgType( dbms_lob.substr( in_jms.text_lob, 10 ), v_clob );
      dbms_lob.freetemporary(lob_loc => v_clob);
      RETURN new_msg;
    END jms2msg_t;
    /MetaLink, Oracle Docs and Google didn't help me. I know of the countermeasures against ORA-30625 in user defined types, but I cannot change JMS-Types, So, what could I do?
    Regards,
    Uwe

    Gee, this was a no-brainer. Thanks to cut w/o paste, I lost the initializing line:
    v_oldmsg:=in_jms;The uninitialized JMS object then throws this kind of "null pointer exception".
    Well, at least I got to know a new ORA-code. ;-)

    so, in another class where you need those variable values:

    var buyInLowVar:int;
    var buyInHighVar:int;
    seatInfo = new SeatInfo();
    seatsVar = seatInfo.seats;
    buyInLowVar = seatInfo.buyInLow;
    buyInHighVar = seatInfo.buyInHigh;

  • Get and Set Parameter ID in BDC Call transaction

    Hi all
    I have written this BDC program to run a transaction eg33  to install meter. After meter get installled System generates  Device location number.

    i think there might be some time gap between CALL TRANSACTION and GET PARAMETER ID.....,that is to say,the new No. has not been generated and what you fetch is an old No..
    i think you should use the "CALL TRANSACTION" like the following one:
    CALL TRANSACTION 'EG33' USING BDCDATA MODE 'A'  UPDATE 'L'  MESSAGES INTO IT_MESS .
    then i think you can get the right value.
    P.S: the different update model(from SAP document)
           upd Effect
    "A"   Asynchronous update. Updates of called programs are executed in the same way as if in the             COMMIT WORK statement the AND WAIT addition was not specified.
    "S" Synchronous processing. Updates of the called programs are executed in the same way as if in the COMMIT WORK statement the AND WAIT addition had been specified.
    "L" Local update. Updates of the called program are executed in such a way as if the SET UPDATE TASK LOCAL statement had been executed in it.
    Other As for "A".

  • How do I get and set column attributes in a table or a treetable with Java?

    Using 11.1.1.4.0
    Hi,
    How do I get and set column attributes in a table or a treetable with Java? For a simple example, say I have a table and want certain roles to see all columns (including address), and other roles can see only certain columns (no address). In a Java method, I want to test if a table's column visible attribute is true and if so, set it to false before rendering it.
    Thanks in advance,
    Troy

    Hi,
    this use case would be a perfect example for using seeded MDS customization. Instead of checking what users are allowed to see or not upon rendering time, you have a customization class and thus the framework doing this for you.
    http://www.oracle.com/technetwork/developer-tools/adf/learnmore/31-mds-sample-169173.pdf
    In this paper and sample, specific users see different layouts. It also contains a customization class that shows how this can leverage ADF Security

  • HashSet get() and contains() methods, by value or reference?

    All the tutorials I've seen on HashSets use Strings as the object type. With Strings, it seems the get() and contains() methods work by value, not by reference.
    <CODE>
    String s1 = "dog";
    String s2 = "cat";
    String s3 = "dog";
    HashSet<String> set = new HashSet<String>();
    set.add(s1);
    System.out.println(set.contains(s1)); //true;
    System.out.println(set.contains(s2)); //false
    System.out.println(set.contains(s3)); //true
    </CODE>
    But when I use a custom object, it works by reference:
    <CODE>
    MyClass c1 = new MyClass("dog", 1);
    MyClass c2 = new MyClass("cat", 1);
    MyClass c3 = new MyClass("dog", 2);
    MyClass c4 = new MyClass("dog", 1);
    HashSet<MyClass> myClassSet = new HashSet<MyClass>();
    myClassSet.add(c1);
    System.out.println(myClassSet.contains(c1)); //true
    System.out.println(myClassSet.contains(c2)); //false
    System.out.println(myClassSet.contains(c3)); //false
    System.out.println(myClassSet.contains(c4)); //false
    </CODE>
    ("MyClass" is a simple class that holds a String and an int).
    Is there any way I can get the set to select by value rather than reference for objects that aren't String?
    If so, is it possible that the value test could be customised, so that, for example, the above will return true if the String in MyClass is the same, regardless of the int value?

    However, as DrClap pointed out, you've mis-diagnosed the problem:
    System.out.println(s1 == s1);
    System.out.println(s1 == s2);
    System.out.println(s1 == s3));would print out the exact same results.
    For an explanation why, Google "Java String pool" or try [url http://stackoverflow.com/questions/3297867/difference-between-string-object-and-string-literal]here.
    If so, is it possible that the value test could be customised, so that, for example, the above will return true if the String in MyClass is the same, regardless of the int value?Absolutely. But, as others have said, you'd need to override equals() and hashCode().

  • Over riding hashtable get and put method

    Hi all
    Anyone have any idea about over ride HashTable get() and put(). Is it possible to over ride HashTable methods.

    Yes_me wrote:
    I want to change the structure of the java HashTable get and put method. As put method is having two object parameters I want to send one more parameter as String to it. Is it possible to change the structure in this way.What would you want to be returned when calling get()? I would go with the suggestion to create a class to keep that information. If you really want to, you can completely hide that information class inside your extended HashTable. You could create an overloaded put method that takes three parameters and then creates an instance of the information class and put that into the map. If you only want the data for display only, the get method could get the information class mapped to the given key, then simply return a nicely formatted String containing the two values.

  • Bug in "Get and Set Time.vi" example for RT systems

    There is a bug in "Get and Set Time.vi" that ships as an example in the "NI System Monitor" package.  The routine does *NOT* return the hour correctly.
    Note the string "%#H:12:39.371" as the time of day.  That should be 09:12:39.371 as it was 9 AM at the time.
    Mac OS X 10.8.5
    LabVIEW 14-64bit
    NI System Monitor 14.0.1
    Pharlap RT PXI embedded system version 14.0 updated.
    NOTE: it is odd that the default "New Time" has #H as the hour but that is hard wired into the VI as a sentinel case.

    Rahul,
    It may be only in the Mac OS X code base.  But since it is one of those annoying locked VIs I can't tell.  Now of course this is locked because communication with the RT system is so sensitive or just plain messy.  My guess is that if I thow wireshark at it I can tell you what is inside and it shouldn't be that secret.
    But let me know what you find running under Mac OS X.

  • How to get and set graph propertis using UIGraph instance

    Hi,
    I have added barGraph graph component on *.jspx and also added buttons like "Get properties" and "Set Properties". On "Get Properties" button action, I want to get all the attrributes of barGraph using UIGraph and also want to get "getGroupAttributes" and "getSeriesAttributes".
    I saw examples on gettiing the Group attributes using the click event on the graph.
    Is there any way to get the attributes on some button action like "Get Properties" without any click event on graph?
    Thanks,
    Gopal

    [Copying the answer here from the internal forum discussion so that other customers can benefit]
    Hi Gopal,
    You can call getValue on the UIGraph to get the GraphDataModel, then to use the data access APIs from there.
    Once you get the DataAccess from the GraphDataModel, you can call getMemberMetadata to get the members on the row and column edge.
    This method is documented in the interface CDFDataAccess:
    http://docs.oracle.com/cd/E16162_01/apirefs.1112/e17492/oracle/dss/util/CDFDataAccess.html#getMemberMetadata%28int,%20int,%20int,%20java.lang.String%29
    You should use the following constants for the series and groups:
    DataDirector.COLUMN_EDGE=groups
    DataDirector.ROW_EDGE=series
    Use the method getEdgeExtent to find out how many members are in the series and groups:
    http://docs.oracle.com/cd/E16162_01/apirefs.1112/e17492/oracle/dss/util/CDFDataAccess.html#getEdgeExtent%28int%29
    Method getLayerMetadata is the correct way to get the names of the layers, a.k.a "dimensions" displayed in the graph.
    DataAccess is used to read the data from the Graph. You set the data in the Graph by setting tabular data, using data binding by dragging and dropping from the data control palette, or by implementing a custom DataSource and setting it on the graph.
    http://docs.oracle.com/cd/E16162_01/apirefs.1112/e17492/oracle/dss/dataView/CommonDataview.html#setDataSource%28oracle.dss.util.DataSource%29
    However, implementing a custom data source is not trivial, and you should only use that approach if you can't use tabular data or regular binding against the available data controls.
    This doc chapter might help in understanding data source requirements for different Graph types:
    http://docs.oracle.com/cd/E16162_01/web.1112/e16181/dv_graph.htm#CEGBGCDG
    Hope this helps,
    Katia
