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.

    Hello

    You use a Singleton class as (class ModelLocator) If Yes, then you can put a single instance of your connection class in this class so that you can access this instance in the world in any component (infact with the app).

    Declare an instance of the connection object in the Singleton class like below

    var logincomp:Login = new login());

    Set the values in a single component, and you can access the values in the other component.

    The sample class Singleton as shown below...

    package com.model
    {

    [Bindable]
    public class ModelLocator
    {
    private static var instance: ModelLocator;
     
    public var logincomp:Login = new login());
     
    public void ModelLocator()
    {
    If (instance! = null)
    {
    throw (new Error ("cannot only one instance of ModelLocator"));
    }
    }
    Public Shared function getInstance (): ModelLocator
    {
    if(instance == null)
    {
    instance = new ModelLocator();
    }
    return instance;
    }
    }

    How to get and set the length and the width of the content of the layer

    All layers are packed not equal. a layer as adjustment have no limits. Layer to smart object can have two different sizes. The size of the object and the size of the object may be transformed. All smart object layers have an associated transform. To transform a smart object layers you need to work with the size of the object the generated pixels fot the layer. Text layer can be resized with a transform or by changing the font size. Pixelated layers are resize via a transformation.  The script method is resize.  When you resize the number of pixelsits made by interpolation. You can specify what method to use or set Photoshop interpolation preferably by default.

    There is also a bug in Photoshop scripts if you pause the story said make a selection and use resize. Photoshop will properly support up to a State before where you suspended history. This bug seems to be in all versions of Photoshop.

    If you look ate the script in my bug report, you should get a good idea of how to resize a layer.

  • How to get and set values a HSlider

    Hello

    I haven't used flex for a while and I'm a little slow today.  My question is simple: how to get and set my HSlider values in a class.  My HSlider lives in an mxml file and class lives in a separate actionscript file.  First of all, I want to get the value of the hslider.  I use property change in the hslider to call a method in my class called Update(. ) In my class, I have the function called Update() and Interior using the id of the cursor to get the value of it.  The compiler is complainiing of 1120: access of undefined property hslider. I gave an example of pseudocode below:

    MXML

    < mx:HSlider id = minimum "hslider" = "0" maximum = "100" value = "100" dataTipPlacement = 'top' tickColor = '0 x 323232 '.
    snapInterval = "1" tickInterval = '10' allowTrackClick = "true".
    liveDragging = "true" change = "aClass.Update ()" / > "

    as file

    public void Update (): void {}
    myVar = hslider.value / 100.0;
    }

    Think how and then set the value of the hslider?

    Maybe the update to this other file function must accept a parameter of the event and then you can probably get this value from the event

    or maybe give the function a parameter of the cursor

    change = "AClass.Update (hslider.value)" "

    public void Update(value:int):void {}
    myVar = value / 100.0;
    }

    private void dumpAMPoolStatistics() {}

    Download the pool manager

    PoolMgr poolMgr = PoolMgr.getInstance ();

    get the managed pools

  • Get and set a Position of the pre-numbered WPF legend

    I'm creating a WPF application that displays a chart of data (several courses) and adds several annotations programmatically. The user has the ability to drag the annotation (InteractionMode = AnnotationInteractionModes.DragLabel) labels. I need to be able to record the new position of the label and load it later.

    I use the NationalInstruments.Controls.PointAnnotation a NationalInstruments.Controls.Graph object.

    I thought it would be reflected in the LabelAlignment, but that does not change the value that I set when I initially create the annotation of.

    Here's how I add the annotations on the graph:

    /// 
            /// Add the annotations to the graph
            /// 
            /// 
            /// 
            /// 
            private void DisplayAnnotations(DataHandler dataHandler, DateTime StartDate, DateTime EndDate)
            {
                PointAnnotation tmpAnnotation = new PointAnnotation();
                //Iterate through all the annotations in the source data set
                foreach (Post_Job_Charting.Annotation dataPointAnnotation in dataHandler.Annotations)
                {
                    TimeSpan DateDiff = EndDate - StartDate;
                    TimeSpan HalfWay = new TimeSpan(StartDate.AddSeconds(DateDiff.TotalSeconds / 2.0).Ticks);
    
                    //Only add annotations that are in the visible data range
                    if (dataPointAnnotation.Date >= StartDate && dataPointAnnotation.Date <= EndDate)
                    {
                        tmpAnnotation = new PointAnnotation();
                        tmpAnnotation.HorizontalPosition = dataPointAnnotation.Date;
                        tmpAnnotation.VerticalPosition = dataPointAnnotation.Value;
                        tmpAnnotation.Label = dataPointAnnotation.Text;
    
                        if (dataPointAnnotation.Date.Ticks < HalfWay.Ticks) { tmpAnnotation.LabelAlignment = new AnnotationLabelAlignment(BoundsAlignment.None, 0, -25); }
                        else { tmpAnnotation.LabelAlignment = new AnnotationLabelAlignment(BoundsAlignment.None, -75, -25); }
                        tmpAnnotation.InteractionMode = AnnotationInteractionModes.DragLabel;
    
                        //Show/Hide the annotation
                        if (dataPointAnnotation.Display) { tmpAnnotation.Visibility = System.Windows.Visibility.Visible; }
                        else { tmpAnnotation.Visibility = System.Windows.Visibility.Hidden; }
    
                        //Tag the annotation so I can find it later
                        tmpAnnotation.Tag = dataPointAnnotation.ID;
    
                        //Display annotation on the graph
                        niGraph.Children.Add(tmpAnnotation);
                    }
                }
            }
    

    Once I have the position of the label, I need to be able to reset the label to this post, but let's start first of all, I need to get this job.

    Any help you can offer would be greatly appreciated.

    Best regards

    -Marcel

    There is no property on the annotation of point that sets the position of the label. I created a task to look by adding this.

    However, you can monitor the changes using a custom BoundsAlignment application that registers the new offset as it is updated:

    public sealed class RecordingBoundsAlignment : BoundsAlignment {
            public Vector LastOffset { get; private set; }

    public override Point AdjustPosition( AlignmentArgs args ) {
                LastOffset = new Vector( args.XOffset, args.YOffset );

    return None.AdjustPosition( args );
            }
        }

    When you create the annotation, you use an instance of the alignment of the record, and when you want to store the position you will be able to read the value of the recorder:

    tmpAnnotation.LabelAlignment = new AnnotationLabelAlignment(
            new RecordingBoundsAlignment( ),
            initialXOffset,
            initialYOffset );

    // ...

    var recorder = (RecordingBoundsAlignment)tmpAnnotation.LabelAlignment.Alignment;
        Save( recorder.LastOffset );

I'm looking to get the dynamic Type via a script object and set it as a variable in the script output, but its does not work. I created the dynamic type using the type dynamic plug-in generator v2.

    I have 'Veeam' namespace with types:

    System.log ("Job found:" + jobOut "');
