- Method Detail
  - connectionError
```
void connectionError(java.lang.Exception e)
```
  - connectionStarted
```
void connectionStarted(Py4JServerConnection gatewayConnection)
```
  - connectionStopped
```
void connectionStopped(Py4JServerConnection gatewayConnection)
```
  - serverError
```
void serverError(java.lang.Exception e)
```
    This method may be called concurrently with serverPostShutdown().
    
    Typically a one thread calls shutdown() and then, the thread running the GatewayServer breaks from the connection accept loop.
  - serverPostShutdown
```
void serverPostShutdown()
```
    This method may be called concurrently with serverStopped() and serverError().
    
    Typically a one thread calls shutdown() and then, the thread running the GatewayServer breaks from the connection accept loop.
  - serverPreShutdown
```
void serverPreShutdown()
```
  - serverStarted
```
void serverStarted()
```
  - serverStopped
```
void serverStopped()
```
    This method may be called concurrently with serverPostShutdown().
    
    Typically a one thread calls shutdown() and then, the thread running the GatewayServer breaks from the connection accept loop.
