iOS Question UnReadOnly Map.IsReadOnly?

[Mashiane]

Hi there

To my surprise my b4a code for mapping works however in my b4i app, same code, the maps are returned as IsReadOnly = True.

Is there a quick way to male IsReadOnly = False in a map, because now I'm thinking of copying the map to a new map variable.

Thanks

You will need to copy the map. You can do it manually or use B4XSerializator (iRandomAccessFile library)

Sub CopyMap(m As Map) As Map
   Dim ser As B4XSerializator
   Return ser.ConvertBytesToObject(ser.ConvertObjectToBytes(m))
End Sub

End Sub

Thanks a lot, thought of such and had already written a loop function. This will do..

I had done this...

Sub UnReadOnlyMap(sourceMap As Map) As Map
    ' copy a map to a new map to make it IsReadOnly = False
    If sourceMap.IsReadOnly = False Then Return sourceMap
    ' the map is readonly, convert it
    Dim newMap As Map
    newMap.Initialize
    ' copy each map item
    For Each key As String In sourceMap.Keys
        Dim val As Object = sourceMap.Get(key)
        newMap.Put(key,val)
    Next
    Return newMap
End Sub
