Field Detail

### pipe

    private jcifs.smb.SmbNamedPipe pipe

  The shared named pipe.

Constructor Detail

### SharedNamedPipe

    public SharedNamedPipe(ConnectionJDBC2 connection)
                    throws java.io.IOException

  Creates a new instance of `SharedNamedPipe`.
  Parameters:
    `connection` -
  Throws:
    `java.io.IOException` - if the named pipe or its input or output streams do not open
    `java.net.UnknownHostException` - if host cannot be found for the named pipe

Method Detail

### isConnected

    boolean isConnected()

  Get the connected status of this socket.
  Overrides:
    `isConnected` in class `SharedSocket`
  Returns:
    true if the underlying socket is connected

### close

    void close()
         throws java.io.IOException

  Close the socket (noop if in shared mode).
  Overrides:
    `close` in class `SharedSocket`
  Following copied from class: `net.sourceforge.jtds.jdbc.SharedSocket`
  Throws:
    `java.io.IOException` - if the socket close fails

### forceClose

    void forceClose()

  Force close the socket causing any pending reads/writes to fail.

  Used by the login timer to abort a login attempt.
  Overrides:
    `forceClose` in class `SharedSocket`

### getPipe

    private jcifs.smb.SmbNamedPipe getPipe()

  Getter for `pipe` field.
  Returns:
    `SmbNamedPipe` used for communication

### setPipe

    private void setPipe(jcifs.smb.SmbNamedPipe pipe)

  Setter for `pipe` field.
  Parameters:
    `pipe` - `SmbNamedPipe` to be used for communication

### setTimeout

    protected void setTimeout(int timeout)

  Set the socket timeout.

  Noop for now; timeouts are not implemented for SMB named pipes.
  Overrides:
    `setTimeout` in class `SharedSocket`
  Parameters:
    `timeout` - timeout value in milliseconds
