  - getAsyncRemote
```
public RemoteEndpoint.Async getAsyncRemote()
```
    Description copied from interface: Session
    
    Return a reference a RemoteEndpoint object representing the peer of this conversation that is able to send messages asynchronously to the peer.
    
    Specified by:
    
    getAsyncRemote in interface Session

    Specified by:
    
    getBasicRemote in interface Session
    
    Returns:
    
    the remote endpoint.
  - isOpen
```
public boolean isOpen()
```
    Description copied from interface: Session
    
    Return true if and only if the underlying socket is open.
    
    Specified by:
    
    isOpen in interface Session
    
    Returns:
    
    whether the session is active.
  - close
```
public void close()
           throws java.io.IOException
```
    Description copied from interface: Session
    
    Close the current conversation with a normal status code and no reason phrase.
    
    Specified by:
    
    close in interface java.io.Closeable
    
    Specified by:
    
    close in interface java.lang.AutoCloseable
    
    Specified by:
    
    close in interface Session
    
    Throws:
    
    java.io.IOException - if there was a connection error closing the connection.
  - close
```
public void close(CloseReason closeReason)
           throws java.io.IOException
```
    Description copied from interface: Session
    
    Close the current conversation, giving a reason for the closure. The close call causes the implementation to attempt notify the client of the close as soon as it can. This may cause the sending of unsent messages immediately prior to the close notification. After the close notification has been sent the implementation notifies the endpoint's onClose method. Note the websocket specification defines the acceptable uses of status codes and reason phrases. If the application cannot determine a suitable close code to use for the closeReason, it is recommended to use CloseReason.CloseCodes.NO_STATUS_CODE.
    
    Specified by:
    
    close in interface Session
    
    Parameters:
    
    closeReason - the reason for the closure.

```
    Deprecated. please use addMessageHandler(Class, javax.websocket.MessageHandler.Whole) or addMessageHandler(Class, javax.websocket.MessageHandler.Partial)

    Description copied from interface: Session
    
    While the session is open, this method returns a Map that the developer may use to store application specific information relating to this session instance. The developer may retrieve information from this Map at any time between the opening of the session and during the onClose() method. But outside that time, any information stored using this Map may no longer be kept by the container. Web socket applications running on distributed implementations of the web container should make any application specific objects stored here java.io.Serializable, or the object may not be recreated after a failover.
    
    Specified by:
    
    getUserProperties in interface Session
    
    Returns:
    
    an editable Map of application data.
  - getDistributedProperties
```
public java.util.Map<java.lang.String,java.lang.Object> getDistributedProperties()
```
    Description copied from interface: DistributedSession
    
    Get distributed properties.
    Values put into this map must be Serializable or serializable by other, implementation-dependent alternative.
    Content of this map is synchronized among all cluster nodes, so putting an entry on any of the nodes will be visible on all other nodes which have reference to current session (in form of TyrusSession or RemoteSession).
    Please note that when not running in the distributed environment, this map behaves similarly to Session.getUserProperties(), so no serialization or deserialization is performed when values are read from or stored to the returned map.
    
    Specified by:
    
    getDistributedProperties in interface DistributedSession
    
    Returns:
    
    map of distributed properties.
