Wish Get & Set

[powerino]

Hi, it would be nice if it were possible to automatically create the "GET" and "SET" methods of the classes, like C # does, so you don't have to write or copy / paste code

In the meantime we have a good Helper:

ClassCreator

I've made a more complete version of my ClassCreator (posted here). Basicly you can create your getter or setters from the variables of a class, even if they are seperated with a comma. Source code is included, feel free to do whatever you want with it.

B4X is a RAD programming language. In Java and C#, public fields are discouraged and instead you are expected to create getters and setters. This is not the case in B4X.
Start with a public field and later switch to getters and setters if you need to add more logic.

Thankyou Jorge and thankyou Erel

public fields are discouraged

Off topic, but What's the reason behind this? does it apply to the development of a class?

I think just because you (the class) cannot check-validate values, instead using properties you can.

(the class) cannot check-validate values, instead using properties you can.

I honestly don't see the difference in a class module , whereas it's more obvious in a Custom View.
Could you show me with a simple example what you mean please?

Could you show me with a simple example what you mean please?

' MyClass1
Process_Globals
    Public Value As Int


' If Value was Zero, error.
' You could check it here, of course, but Value could be used also in many other routines.
Public Sub Divide(Num As Int) As Single
    Return Num / Value
End Sub

' MyClass2
Process_Globals
    Private mValue As Int = 1

Public Sub setValue(V as Int)
    If V >= 0 Then
        mValue = V
    Else
        '...
    End If
End Sub
Public Sub getValue As Int
    Return mValue
End Sub

' mValue will never be zero.
Public Sub Divide(Num As Int) As Single
    Return Num / mValue
End Sub

not ideal example, but I'm watching the news

 

[Jorge M A]

ooooh! i see my mistake!!!!
I understood exactly the opposite, sorry!
(it's early morning here, lack of coffee and also watching news)

 

[LucaMs]

it's early morning here,

there?

 

[Jorge M A]

there?

Once I felt a certain discriminatory attitude from someone who is not worth it. I'm not going to deepen it. Just try to avoid it again.

 

[LucaMs]

from someone

One stupid out of over 100,000 is expected.
