Wish Initialize variable, types, list, etc. by the key word "new"

[Alexander Stolte]

Hey, i'm working with Visual Studio every day and there is a Feature to Initialize all with the keyword "new" for example:

Dim str as new string
Dim mytype as new nicetype

You could initialize lists for example in the Process_Globals already at the declaration.

Would that be possible someday?

Dim str As String = "abc"
Dim MyList As List = Array(1, 2, 3, 4)
Dim MyMap As Map = CreateMap("key1": "value1")

About types, see the latest version of B4J: https://www.b4x.com/android/forum/threads/b4j-v8-00-has-been-released.111727/#content
There is a new 'generate CreateType' feature.

With this feature you can write:

Dim MyType As NiceType = CreateNiceType(...)

 

[LucaMs]

Dim MyList As List = Array(1, 2, 3, 4)

This is "dangerous", because after this kind of initialization, the List loses its characteristics (it becomes practically an array).
I will never initialize it that way

 

[Erel]

Not really dangerous. It depends on your requirements.

If you want to create a mutable list then write it like this:

Dim list As List
list.Initialize
list.AddAll(Array(1, 2, 3))

Or:

Sub CreateMutableList(Items As List) As List
 Dim list As List
 list.Initialize
 list.AddAll(Items)
 Return list
End Sub

Dim list As List = CreateMutableList(Array(1, 2, 3))
list.Add(4)
