  - getPort
```
public int getPort()
```
    Description copied from interface: Connection
    
    The remote port.
    todo: rename to getRemotePort? And do we need it because we already have getEndPoint which returns an address which includes port. It is only used in testing

    getPort in interface Connection
    
    Returns:
    
    the remote port number to which this Connection is connected, or 0 if the socket is not connected yet.

    Returns the address of the endpoint this Connection is connected to, or null if it is unconnected.
    
    Specified by:
    
    getRemoteSocketAddress in interface Connection
    
    Returns:
    
    address of the endpoint.
    todo: do we really need this method because we have getInetAddress, InetSocketAddress and getEndPoint.
  - isAlive
```

    Description copied from interface: Connection
    
    Checks if the Connection is alive.
    
    Specified by:
    
    isAlive in interface Connection
    
    Returns:
    
    true if alive, false otherwise.
  - lastWriteTimeMillis
```
public long lastWriteTimeMillis()
```
    Description copied from interface: Connection
    
    Returns the clock time in milliseconds of the most recent write using this connection.
    
    Specified by:
    
    lastWriteTimeMillis in interface Connection
    
    Returns:
    
    the clock time of the most recent write.
  - lastReadTimeMillis
```
public long lastReadTimeMillis()
```
    Description copied from interface: Connection
    
    Returns the clock time in milliseconds of the most recent read using this connection.
    
    Specified by:
    
    lastReadTimeMillis in interface Connection
    
    Returns:
    
    the clock time of the most recent read
  - getEndPoint

    Specified by:
    
    getEndPoint in interface Connection
    
    Returns:
    
    the Address.
  - setEndPoint
```
public void setEndPoint(Address endPoint)
```
  - setErrorHandler
```
public void setErrorHandler(TcpIpConnectionErrorHandler errorHandler)

  - write
```
public boolean write(OutboundFrame frame)
```
    Description copied from interface: Connection
    
    Writes a outbound frame so it can be received by the other side of the connection. No guarantees are made that the frame is going to be received on the other side.
    The frame could be stored in an internal queue before it actually is written, so this call does not need to be a synchronous call.
    
    Specified by:
    
    write in interface Connection
    
    Parameters:
    
    frame - the frame to write.
    
    Returns:
    
    false if the frame was not accepted to be written, e.g. because the Connection was not alive.
  - equals
```
public boolean equals(Object o)
```
    Overrides:
    
    equals in class Object
  - hashCode
```
public int hashCode()
```
    Overrides:
    
    hashCode in class Object
  - close
```
public void close(String reason,
                  Throwable cause)
```
    Description copied from interface: Connection
    
    Closes this connection.
    Pending packets on this connection are discarded
    If the Connection is already closed, the call is ignored. So it can safely be called multiple times.
    
    Specified by:
    
    close in interface Connection
    
    Parameters:
    
    reason - the reason this connection is going to be closed. Is allowed to be null.
    
    cause - the Throwable responsible for closing this connection. Is allowed to be null.
  - setBinding
```
public boolean setBinding()
```
  - getCloseCause
```
public Throwable getCloseCause()
```
    Description copied from interface: Connection
    
    Gets the cause this Connection was closed. Can be null if no cause was given or if the connection is still active. It is purely meant for debugging to shed some light on why connections are closed. This method is thread-safe and can be called at any moment.
    
    Specified by:
    
    getCloseCause in interface Connection
    
    Returns:
    
    the cause of closing this connection.
    
    See Also:
    
    (), Connection.close(String, Throwable)
  - getCloseReason
```
public String getCloseReason()
```
    Description copied from interface: Connection
    
    Gets the reason this Connection was closed. Can be null if no reason was given or if the connection is still active. It is purely meant for debugging to shed some light on why connections are closed. This method is thread-safe and can be called at any moment. If the connection is closed and no reason is available, it is very likely that the close cause does contain the reason of closing.
    
    Specified by:
    
    getCloseReason in interface Connection
    
    Returns:
    
    the reason this connection was closed.
