B4J Question [JNetwork] How do I detect which socket has been disconnected?

[Waldemar Lima]

Hello Everyone !
How do I detect which socket has been disconnected?

my code :

Sub Class_Globals
    Dim AStreams As AsyncStreams
    Dim Server As ServerSocket
    Dim Socket1 As Socket
End Sub

'Initializes the object. You can add parameters to this method if needed.
Public Sub Initialize
    Server.Initialize(5500, "Server")
    Server.Listen
    Log("MyIp = " & Server.GetMyIP)
End Sub

Sub Server_NewConnection (Successful As Boolean, NewSocket As Socket)
    If Successful Then
       
        Socket1 = NewSocket
        Log(Socket1)
        'Can only use prefix mode if both sides of the connection implement the prefix protocol!!!
        AStreams.InitializePrefix(Socket1.InputStream, False, Socket1.OutputStream, "AStreams")
    Else
        Log(LastException.Message)
    End If
    Server.Listen
End Sub

Sub AStreams_NewData (Buffer() As Byte)
    Dim msg As String
    msg = BytesToString(Buffer, 0, Buffer.Length, "UTF8")
    Log(msg)
End Sub

Sub AStreams_Error
    Log(LastException.Message)
    Log("AStreams_Error")
End Sub

Sub AStreams_Terminated
    Log("AStreams_Terminated")
   ' HOW CAN I GET THE DISCONNECTED SOCKET ?
End Sub

If you want to handle multiple connects then move the code with Socket1 and AStreams to a class. This will make it very simple to distinguish between different connections.

I think you can get that in the astream_error event:

Dim astream As AsyncStream = Sender
