Android Question how to browse a Map of Types?

[ThePuiu]

I have the following code:

Type ZiLucru(key as Int, Data As Long, ListaEchipe As Map)
Dim Taskuri As Map

....................

Dim mcal As Map = CreateMap("POPESCU":1,"IONESCU":2)
Dim mcal1 As Map = CreateMap("MARINESCU":3,"PANTEA":3)

Dim jobs As ZiLucru
jobs.Initialize
jobs.key = 1
jobs.Data = DateUtils.SetDate(2019,4,1)
jobs.ListaEchipe.Initialize
jobs.ListaEchipe = mcal
    
jobs.Initialize
jobs.key = 2
jobs.Data = DateUtils.SetDate(2019,4,2)
jobs.ListaEchipe.Initialize
jobs.ListaEchipe = mcal1
    
Taskuri.Initialize
Taskuri.Put(mcal, jobs.Data)
Taskuri.Put(mcal1, jobs.Data)

how can I get "Taskuri" Map values for a given "key" value?

Thank you!

If I got it right, you could to go through all the values and stop when the key is found.

Dim keyFound as Boolean = False
For Each mapKey As Map In m
    Dim value As ZiLucru = m.Get(mapKey)
    If value.key = the_key_you_are_looking_for Then 
        ' Do something if the key is found

        keyFound = True
        Exit
    End If
Next

If keyFound = False Then
    ' Do something if the key is not found

End if

Ah, and I noticed that you are re-initializing "jobs" (for the second time) before adding it to Taskuri.
So, at the end, you are adding two times the second "jobs", which makes the first one useless.

the two inserts lead to the insertion of both objects into the Taskuri structure ... see the picture


Or is there a simpler method of navigating through a structure similar to the one in the image?

 

[Marcus Araujo]

It does lead the insertion of both items but only their keys (mcal and mcal1). Their values are the same (jobs.Data) but should be different dates, right?

I am afraid there's no simpler method for navigating the structure the way you proposed, but there may be simpler ways to code what you want to do (I don't know what your goal is, but I have a hunch that Lists might help).

 

[ThePuiu]

yes, you are right about jobs.Data.

I couldn't stand for help anymore and I changed the concept ... now I'm using json and everything works perfectly.
thank you for your involvement!
