Modifier and Type	Method	Description

- Method Detail
  - onClose
```
void onClose(CloseReason reason)
```
    Called when session is being closed.
    
    Parameters:
    
    reason - reason for session being closed
  - onRedundancyStateChanged
```
void onRedundancyStateChanged(RedundancyStateType redundancyState)
```
    Called when D2000 kernel redundancy state has been changed. It happens when multiple instances of kernel are joined in redundancy group and state of being "hot" is transferred from one instance to another.
    Note: While redundancyStateChange is being executed D2Session.getRedundancyState() returns previous state. It changes to the current state immediately after this call returns.
    
    Parameters:
    
    redundancyState - current state of kernel that the session is attached to
  - onRTIReceived
```
void onRTIReceived(java.lang.String command)
```
    Called when asynchronous RTI command is received.
    
    Parameters:
    
    command - raw command string
  - onSessionCreated
```
void onSessionCreated(D2Session session)
```
    Called when new session is created.
    
    Parameters:
    
    session - new session instance
  - onTerminateRequest
```
void onTerminateRequest()
```
    Called when kernel issues terminate request to the current session instance.
