• Is it OK to have no constant fields in an enum type?

  Hello!
  
  I was wondering if it is good or bad to have no constant fields in the enum types (which would be modified during execution of the program)
  My question is if it goes against the semantics and idioms.
  
  Here is an example of what I want to do:

  public enum ChessPieceColor {
  
      BLACK,
      WHITE;
  
      // Reference to the player who plays the given color
      private Player player;
  
      public void setPlayer(Player player) {
  
          this.player = player;
  
      }
  
      public Player getPlayer() {
  
          return player;
  
      }
  
  }

  It would be a game of chess, where the chess pieces would be a color based on the enum. And if I want to know which player plays a certain color, I can do: ChessPieceColor.BLACK.getPlayer)
  
  It is an important work at home so I would have someone's opinion whether or not it is an acceptable design.
  
  I hope someone can help
  Thank you very much!

  Personally, I don't think it's a good idea.

  Your statement implies somewhat that a player is member of BLACK and BLACK is a member of ChessPeiceColor, that sounds wrong.
  ChessPieceColor.BLACK.getPlayer)

  Also, in the light of the foregoing, when I see a term all in capitals as the BLACK, I think of it, which represents a constant by convention and therefore has functions.

  What about using:
  A player = ChessBoard.getPlayer (ChessPieceColor.BLACK);
  That said, only a chess board has a player who plays the BLACK position.
  (Note: when the player is instansiated, it must store as a variable what position his reading: black or white)

• Casting of object type to aid to more specific

  Hello

  I'm bit stuck in the legacies of the class in my current project. I implement a zero-coupling messaging architecture that uses variant tables to store objects to be cast to sample.

  The good news: it works in general, little we take a peek at some photos

  I tried the script of coulee before using an example that works as expected.

  

  Shows probe resulting:

  

  The Message of abstract [14] is cast to the more specific Message for the controller test [15], [9]

  Now, this implementation with the variants table, change things unfrotunately:

  

  The only thing that apparently changes is, as the class to be cast to a return value of a Subvi (actually reading the table variant) [12].

  As shown in the probe that the casting does not work this time... There is also no error on the terminal error.

  I have to admit, I'm quite confused... especially because in another class this exact methodiolgy works...

  Any thoughts?

  See you soon

  Oli

  Cast throws more specific to the type of object shown on the thread in the IDE, regardless of the type of the actual object passing along this thread (i.e. type of YARN and not DATA type).

  I bet that your wire to the Center terminal of the 'to more specific' is a son of the same type as the object you are trying to change but actually a more specific object.  The 'Cast to more specific"is a compiling decision, not a decision of execution. As such it takes the type of thread, not the object type for the casting.

  Look at the names on the left of your probes, they are all the same in the example below (all wires are nominally of the same type).  It's the onfo LV casting (assuming the names corresponding to the nominal type of the thread) not use content REAL of the wire.

  Shane.

  PS to make things clearer, give each hierarchy in your legacy a different aspect of wire.

• Enum (type def) - structure of the case called update error

  Hello

  1. One of my (type def) enums is not updated the names of structure cases. I found something that looks like a probable error in the case where the structure,
  2. I had created one of the constants in the enumeration before I did a typedef. Therefore, I made new constants since the typedef and replace the original ones. and still, the structure of the case is not being updated.

  How can I solve this?

  also, I have one state machine inside the other. Is this right way to program?

  

  Somewhere in your code, you have the wrong typedef, or don't replace a control by the typedef. Must not have replaced all. I don't know if there is an easy way to search for; You may need to go through anyway.

• Cast: more specific type where the object EXPECTED

  I extend an interface that expects an argument of type Object. My implementation of this interface knows that the object passed is a specific class, I've defined. I can't compile my code no matter what I try, because of the error "incompatible types.

  In my case, I set my own observer / Observable class. Below is the method of observation which does not compile:

      public void update (Observable obj, Object arg) {
          if (arg instanceof Message ) {
              message = arg;
              if (message.success) {
                  System.out.println("received success notification ");
                  // do some other stuff
              } else {
                  System.out.println("received failure notification ");
              }
          } else {
              System.out.println("received notification without a valid Message");
          }
      }
  

  I tried a few other forms that do not work also. I like to keep my interface like that so that I can reuse it in other places. What I really want is to cast 'arg' of a generic object of type "Message", but this does not seem to be supported in the desktop. Thoughts?

  You are missing a cast. Also, I don't see where the variable 'message' has been declared.

  Try this:

  If (arg instanceof Message)

  Message message = arg (Message);

• OracleDataAdapter error: unable to cast object of type 'Oracle.DataAccess.Types.OracleDecimal' type 'System.IConvertible '.

  Uses: Oracle9i Standard Edition, ODAC 11.2.0.4, Oracle Instant Client 11.2.0.4

  I am to convert the Microsoft Oracle for Oracle ODP.NET provider of my projects

  * Error *.

  Cannot be cast to type 'Oracle.DataAccess.Types.OracleDecimal' object type 'System.IConvertible '. Could not store < 145982 > in the RECEIPTID column. Type is Int64.

  This error is poped up when my stored Proc has a return parameter. The return is a numeric data type in Oracle. I had no problem when using Oracle Provider from Microsoft.

  Initially, I had my command setting insert the value

  System.Data.OracleClient.OracleType.Number

  for the column RECEIPTID; After ODP.NET, I converted to

  Oracle.DataAccess.Client.OraclDbType.Double

  Then the error throwed upward. Implement

  Oracle.DataAccess.Client.OracleDbType.Int64

  as suggested by the error, but nothing seems to prevent the error a way.

  I am running using the OracleDataAdapter.

• Casting to a type of data

  In order to cast a data in another type, which is the difference between the use of functions like TO_NUMBER TO_CHAR,... and using the CAST function AS? Thank you!

  Cast can be used with collections
  say you want to convert a set of values in a collection that is not possible by to_number or To_char

  for example:

  SELECT CAST(MULTISET(
      SELECT object_name, object_type
      FROM user_objects
      WHERE rownum <10) AS collection_type)
    INTO collection_type

  You cannot use local collection types in SQL. You must create a bin_array of type like nested SQL table type. In addition, depending on the version you will not cast:

• [ADF, JDev12.1.3] Page of the input parameters: 1) expression for a value of type enum? (2) can they be used to initialize CIU?

  Hallo,

  I have a backingBean extended myBean bean 'associate' to a page fragment used in a stubborn workflow.

  I want to declare to the fragment in the settings of btf 2 who have a fixed value. Their values should be copied in 2 myBeanattributes.

  An attribute is Boolean, and I guess it does not give any problem, but the other is to an enum type that is defined in the myBean bean itself.

  I have to write in "value *" pass the enum value to var enum in myBean?

  

  And if the "value *" have been a public static final string of a Java class in the application Module which expression I should use?

  I would like to use parameters of entry Page to initialize (hide, show,...) in myBean some component of the user interface in the page fragment? Is this possible without intervention in any problem? Can kindlu give you some tips to achieve this?

  Thank you

  Federico

  It also works with range backingBean?

  I don't know (I just created a few vars inside managed bean in my application of playground).

  The fragment contains a search with table form and it's always the same, whereas the bean (containing the search called action when the user clicks on the button 'Search') should take the page settings to compose the search query according to them.

  Yes, but that are not exactly 'page settings' because you retrieve the values of the url of the page, right?

  In conclusion, the problem is that I should switch to the different settings depending on the btf bean where the fragment is used.

  You have a better idea to achieve this?

  Then why you are not using the BTF settings (they will be in pageFlowScope)

• Simulink Inport/Outport data types

  I searched for a while and I am unable to find documentation about what types of data I need to use the inports, outport, settings and in my Simulink models.

  Is there some specific types of data that are, or are not supported?  How VeriStand to determine how to coerce data to send the model?  Also, I was under heard VeriStand uses doubles for everything but then I saw a post that says he uses of I64.

  Any clarification would be much appreciated.

  VeriStand 2013 SP1 (probably upgraded to 2016 in next year if it's relevant)

  MATLAB 2010 b and MATLAB 2012 b (currently)

  > Are there types of specific data that are, or are not supported?

  I don't remember there being any limitation of types beyond what is stated in the considerations help document.

  Considerations relating to the integration of The MathWorks, Inc. Simulink® software models (model Interface T...

  The big hiccup I remember wasn't mainly with types of configurations and data bus.

  IIRC, you can choose any numeric type desired in Simulink. The structure of the model interface that uses VeriStand will handle any type and convert it to double so that it can be consumed by the VeriStand engine.

  > How VeriStand to determine how to coerce data to send the model?

  I think the way it works is that when VeriStand interacts with the Simulink model, it gets a list and information (pointer, data type) of inports, remote villages and settings. Thus, it can capture data from the model (because it has the pointer), and it can cast its data type (because he knows the type) duplicate. If you look at the example model model interface on line 212 it might help to make things more clear on how this could work.

  C:\VeriStand\2016\ModelInterface\custom\examples\template.c

  Double USER_GetValueByDataType (void * ptr, int32_t subindex, int32_t type)
  
  {
  
  	switch (type)
  
  	{
  
  		case 0:
  
  		{
  
  			/ * double * /.
  
  			(double) return (((double *) ptr) [subindex]);
  
  		}
  
  		case 1:
  
  		{
  
  			/ * only * /.
  
  			(double) return (((float *) ptr) [subindex]);
  
  		}
  
    	}
  
  / * return NaN, ok for vxworks and pharlap * /.
  
  	uint32_t nan [2] = {0xFFFFFFFF, 0xFFFFFFFF};
  
  	return *(double*) nan;
  
  }

  I'm guessing that the full implementation of which uses VeriStand is much more complex, but I think that the idea is the same.

  > Also, I was under heard VeriStand uses doubles for everything but then I saw a post that says he uses of I64.

  VeriStand engine uses indeed of all double rooms.

  You happen to remember this post and you can share the link? I'd be curious to see where this is said and in what context.

• Are there different types of references to screw? This example needs to be so complicated?

  "Forced Nonlinear Curve Fit.vi" requires some other VI implements the shape of the model must be adapted and requires a reference to this VI as one of its inputs.

  It seems that there are several kinds of references to screw - why? What are they and how do I know which one to use?

  I have attached a vi that the curve fitting with the vi mentioned above, and it also sets up the reference for the other vi that contains the model, also attached. By the comments, I thought that some simple reference pointing to the model VI would be all he needs, but he seems to need a dynamic reference that has been altered by cast to another type of reference vi. At least, if I understand this right.

  Can anyone shine light on it or hit me somewhere useful? Note that I already saw a context-sensitive help to create references to the screws.
  That's where I got my instructions.

  cebailey,

  If you right-click your static VI reference and select strictly "Typ VI reference", then you can connect in the constraint Nonlinear Curve Fit VI.  The VI curve adjustment uses a call by the reference node, which does not accept that strictly type (specific to a given link pane) references.

  Here are some help of LabVIEW on static references to VI:

• Possibility to use the Enum control as an index for the loop entry For

  Hello world

  I'm curious to know if an ENUM type could be an index entry for a loop For (in fact, I tried in labview but it did NOT work).

  I use Enum to my two configurations (only two elements), but sometimes I need to run the two together.

  I wonder if it has a good structure to manage it, or simply replace ENUM with table.

  Thank you

  Here is an example of use of the nodes of property:

  

• How convert the string in enum by using LabVIEW 7.0

  I learned LabVIEW 8.6, but here at work, so we must use the Solaris workstations built in 95, the more advanced version of LV they will work is version 7.0.  On LV8.6, it was very to change a string to an enum using the format 'text' vi.  On LV7.0, is not available.  I made my own conversion from type vi with a structure of the case, but this is very annoying, because every time I add an element to the enum, I must add something to this vi.  I added the verification code so there is a warning if I add to the enum, but don't forget to update of the conversion of the vi errors.  Is it possible to reproduce the "text format" vi, using LV7.0?

  

  The analysis of primitive string will do the job in LV7.0.  Its a darn good idea to create a control of the enum type-def you use! If the constant and the witness are instances of your type definition, when you change the control (add, delete, rename, swap values) you can press the button to change to apply and PRESTO all your commands, constants and indicators that use the def type are updated with new info.
