Public/private getter/setter methods

• get and set methods: use or not

  Hello

  I am student upward throughout the atcionscript and happened to get and set methods.

  I can't see how they are used, but you can also make custom methods get and set as follows:

  public void getName)

  {

  return name;

  }

  setName (newName) of the public service

  {

  name = newName;

  }

  So my question is which is the best method to use - is there a difference at all.

  ALSO - they seemed very redundant for me at the time that they simply receive a variable, you can get much faster by going directly to a variable.

  Do they have any real use?

  In addition, some schools of coding very strictly apply accessors. This does not mean that this app is really convenient, but it has little reasonable basis.

  Theoretically, it is very safe to just anyone allow direct access to the property. Once again, in theory, we can do much harm to a bare ownership. Of course, most of us do not write shields of industrial strength that an application requires, but in environments where the code is released - it is important to protect the integrity of the code, its encapsulation and impose an extra layer of armor.

  Note that not a single property in full classes AS3 has direct access - all properties are getters/setters or one of them.

  This brings me to another advantage.

  Say, you want the variable value to be read, but not set. If you do the public variable - outside the object can BOTH set and get its value and there NO WAY to stop the value parameter. But, if you provide ONLY getter - nothing can set the value. It becomes read-ONLY.

  Hi Experts,

  -Public

  Configured before installation for each node and can be resolved at this node before installing.
  Role:
  Enable Virtual/SCAN configuration/communication between the nodes in the cluster. Do not start the Clusterware without public IP Interface/address.
  Virtual/SCAN will work as an alias IP on the public Interface on the Public network.

  -Private or interconnection

  Configured before installation, but on a separate private network, with its own subnet, which is not resolved except by other nodes in the cluster member
  Role:
  Clusterware uses for cluster synchronization (network heartbeat) interconnection and communication of demon among the nodes in the cluster.
  RAC uses the interconnect for cache fusion (UDP) and inter-process communication (TCP).
  Cache Fusion is the remote Oracle buffers, shared memory mapping between the caches of the members of the cluster nodes.

  -Virtual

  Configured before installation for each node, but not currently in use. IP, VIP and treats public SCAN addresses than any other addresses on the same subnet.
  Role:
  The goal is the availability of the applications. If add or remove nodes as your remove VIP client config (with SCAN, it is not necessary)
  When a node fails, the VIP associated with it is automatically failed over to another node.
  Without using VIPs or FAN, clients connected to a node who died often wait a TCP timeout (which can be up to 10 min) before getting an error.
  So, you don't have really a good HA solution without using VIPs and FAN. The best way to use the FAN is to use a client integrated with fast connection failover (FCF) such as JDBC, OCI, or ODP.NET.

  -SCAN

  Three static IP addresses that are configured on the server (DNS) domain names prior to installation so that the three IP addresses are associated with the name provided as the SCAN, and all three addresses are returned in random order by the DNS to the applicant
  Configured prior to installation in the DNS to resolve the addresses that are not currently in use. Addresses on the same subnet than all other IP addresses, addresses VIP and public SCAN
  Role:
  The goal is the availability of the applications before clients establish communication with CARS and make the whole of the Cluster completely transparent.
  IP SCANNER is a new 'layer' (oracle) with high availability network that allows to modify the characteristics of your cluster (IE add/remove nodes) without having to change the configuration in their concept of customers 'grid '.
  >

  2. What is the relationship between IP SCAN and virtual IPs?

  IP SCANNER is used to receive new connection requests and redirects to the VIP IP.
  The virtual IP address sets and allow failover of connections after connection is established.

  When the client requests a connection, Oracle Client 11 GR 2 find for IP addresses and create a list of all IP SCAN available for this host-scan, the first attempt to connect to RAC uses one of the available SCAN IP addresses.
  The listener ANALYSIS will receive this connection and re - direct to one of the available using LOCAL_LISTENER nodes from that time the connection is made by using the virtual IP (VIP).

  All SCAN/VIP must be resolved by the DNS.

  The customer knows that there is only the Hostname SCAN, which is configured in the connection string.
  Once the connection is requested Oracle Clusterware redirects the connection to one of the VIP host name must be resolved by the DNS.

• Pushing a value in a table by a getter/setter

  Hey everybody, I think you run into a situation where when I push a value in a table which is held in a singleton via a getter/setter, Flash seem to so access the Get accessor on the Set accessor method.

  in my command/controller (I use RobotLegs)

  override public function execute():void
  {
       // various line of code here
  
       //Place screenshot image into an array from model for later reference.
       model.unitScreenshots.push(screenShot); // screenshot is just a Bitmap object
  }
  

  the getter and setter in my legs singleton model for example robot

  public function get unitScreenshots():Array
  {
       return _unitScreenshots;
  }
  
  
  public function set unitScreenshots(value:Array):void
  {
       _unitScreenshots = value;
  }
  

  When I put a breakpoint on the getter and setter, only the Get accessor method is being called, why?  I think that a value of push on the table would trigger the Set accessor, not the Get accessor, advice?

  Thank you.

  model.unitScreenshots

  fire the Get accessor as you go to unitScreenshots the name of the Get accessor. you found unitScreenshots model in order to access push unitScreenshots method.

  and the push does not access the Set accessor, because you don't specify what to unitScreenshots.

  to access the Set accessor, you would need to write

  var someArray:Array = [12, 23: 45];  or you want to put in it

  model.unitScreenshots = untableau

  you could write something like

  public function set aUnitScreenshot(value:Bitmap):void
{
     _unitScreenshots.push(value);
}

  then call

  override public function execute():void
{
     // various line of code here

  //Place screenshot image into an array from model for later reference.
     model.aUnitScreenshot = screenShot; // screenshot is just a Bitmap object
}

  but it is not very intuative cause you do not actually define anything just add something

• Getter setter problem

  I try to use a Set accessor for two reasons: to set the value of a variable and execute a method. However, when I call the setter of a value where the variable does not change, the Set accessor is unable to run.

  public function set {canvasPosition(value:Number):void}
  _canvasPosition = value;
  model .canvasPosition = _canvasPosition;
  }
  Presumably, the variable leans on its value and said to himself: "my value does not change, so there is no point in the execution of the Set accessor.

  My solution is to call the setter twice:

  controller.canvasPosition = 1;
  controller.canvasPosition = 0;

  This action solves the problem, but there must be a better way! How can I force the installer to run?

  If you accidentally set the predefined function or class it

  can be generated code that calls not less that the value has changed.

  Otherwise, any change control must be in your code.

  Get/set functions, use [Bindable ("someEvent")] and dispatches the event

  themselves.

  To prove it, add a trace statement that transforms the old and the new value and see

  If we trace when the value does not change.

• setAttributeInternal - Set method for attribute... cannot be resolved

  I use JDev 10 g (10.1.3.3) with OA framework. I recently upgraded a project from jDev 9i to 10g. I get this error when you try to set the value of an attribute.
  
  Error:
  Set, method for the attribute \"MonHours\" in WTSHomeAM.WTSTimecardDetailsVO1 cannot be resolved
  
  He comes to the set method:
  public void setMonHours (numeric value)
  {
  setAttributeInternal (MONHOURS, value);
  }
  
  It's the get method:
  public number getMonHours()
  {
  return (Number) getAttributeInternal (MONHOURS);
  }
  
  The attribute is persistent in the EO and VO.
  
  I don't know if this has nothing to do with the question, but in my VORowImpl.java the 'getAttributeInternal' has a strike through the text, as it does not recognize the code.
  
  Any help would be greatly appreciated!

• How to set the attribute of the View object at run time using the setter method

  I'm working on Oralce ADF Insider video of Frank. In fact in this video Frank EmployeeVO departmentId value using a setter method setdepartmentIdVar(). In this video do not see the name of the entire field. I tried with different opportunities and get the following errors.

  If I try with departmentId get this error message: there is no field with the name departmentId in EmployeeView1

  If I try with department_id get this error message: there is no field with the name department_id in EmployeeView1

  If I try with department_id get this error: there is no field with the name department_id in EmployeeView1

  

  This method, it is used in a BTF. Can you please take a look at this video and let me know what should be the name of the field.

  Thanks in advance.

  Simply open EmployeeView and see the correct attributeName, normally it's DepartmentId

  What is see in the picture the viewObject attribute is omitted, it is bind variable name, m I right?

• EOImpl Get accessor method not fill not value...

  I am editing the oaf features seeded & it will be made available as a patch... a req is to add a column to the OE... I added in OT, VO,... .but in the get method EOImpl... getFullSale() is not be filled... If I hard code a value, then it is successfully inserting in a table... but you know whey added column getFullSale() receives no value... I checked in VO.currentrow... It's the filling in a CO... but in EOImpl not gettting.

  
  

  The steps that I followed:

  
  

  1. first I changed the table to add the column extra full_sale to okl_pools_all

  . EOImpl.class seeded appealed to the java package and from there he appealed to the plsql package, here it is put in place and engage in the okl_pools_all table

  2. in Jdev-> EO.xml-> schronize db-> selected column full_sale and generated EOImpl.java which has fullsale code of getter and setter, but call to java seeded pkg is missing.

  3. edition EOImpl.java generated and added code to call to pkg pkg and plsql java stuff.

  4. updated VO.xml and VORowimpl.java to include the setter and getter FullSale methods

  5. transferred to the server and fact apache bounce.

  
  

  It's successfully insertion in the table and do not get value for full_sale. If I hard code in EOImpl.java, it is the insertion. so the problem with the getter in EOImpl method.

  
  

  Please advice

  Check the mapping to VO. Is that the newly created in the t attribute is mapped to the attribute of EO?

  See you soon

• Strange problem of Getter Setter in interface

  Hi people, I have a strange compilation error

  package  {
    public interface IGet{
    function get someInt():int;
    }
  }
  

  package  {
    public interface ISet {
    function set someInt(value:int):void;
    }
  }
  

  package  {
    public interface ISomeInt extends IGet, ISet{
    }
  }
  

  package {
    public class SomeInt implements ISomeInt {
    public function SomeInt () {
    }
    public function set someInt (value:int):void {
    }
    public function get someInt ():int {
    return 157;
    }
    }
  }
  

  package  {
    import flash.display.MovieClip;
    public class InitSomeInt extends MovieClip{
    public function InitSomeInt() {
    var so:ISomeInt = new SomeInt;
    so.someInt = 15;
    }
    }
  }
  

  compiler says: 1059: property is read-only.

  all solutions?

  
  

  
  

  
  

  
  

  put ction someInt

  Just to chime in... I'm not sure how familiar vakhtangi is with ACE and don't want him to get discouraged by false information by a person with a lot of reputation points. He knocks on the interface is the right thing to do and the type of implementation will not help (and of course also will not accomplish the goal of using Interfaces in the first place).

  I think what actually happens are the IGet and ISet are defined separately, then combined in ISomeInt. When you try to set the value, the compiler considers as separate and straightens the first IGet (this is the order specified in ISomeInt), which specifies someInt as a read-only property. It is a strange but not illogical behavior. It's probably an edge case that never took place at Macromedia/Adobe.

• Events on the getter/setter function binding

  I found this snippet, when I was walking in a Flex3.6 project:

                  [Bindable(event='currentPageChanged')]
            public function get currentPage ():int {
                 return this._currentPage;
            }
            
            protected function set _currentPage (value:int):void {
                 if (this._currentPage == value){
                      return;
                 }
                 this.__currentPage = value;
                 this.dispatchEvent(new Event(BookEvent.CURRENTPAGE_CHANGED));
            }
  
            protected function get _currentPage ():int {
                 return this.__currentPage;
            }

  What is it meant to do by declaring an event that can be bound above the getter function immediately?

  Thank you very much.

  No, var age: int = classname.age; will be re-run.  But lets think about that for a second, when classname.age is changed, what is the State of 'age', he might be out of range, or specify a different value, and so on.  DataBinding usually manifests in mxml components tied to the data they represent.  If you want to link 'age' classname.age then you must use BindingUtils and implement binding yourself, it is not difficult but can be weird with its syntax in the beginning.

• Table 2D-strings in the "get/set item property.
