  - ### isReadyForRead

    public boolean isReadyForRead() throws IOException
    Specified by:
      `isReadyForRead` in class `SocketWrapperBase<NioChannel>`
    Throws:
      `IOException`

  - ### read

    public int read(boolean block, byte[] b, int off, int len) throws IOException
    Specified by:
      `read` in class `SocketWrapperBase<NioChannel>`
    Throws:
      `IOException`

  - ### read

    public int read(boolean block, ByteBuffer to) throws IOException
    Specified by:
      `read` in class `SocketWrapperBase<NioChannel>`
    Throws:
      `IOException`

  - ### doClose

    protected void doClose()
    Description copied from class: `SocketWrapperBase`
    Perform the actual close. The closed atomic boolean guarantees this will be called only once per wrapper.
    Specified by:
      `doClose` in class `SocketWrapperBase<NioChannel>`

  - ### flushNonBlocking

    protected boolean flushNonBlocking() throws IOException
    Description copied from class: `SocketWrapperBase`
    Writes as much data as possible from any that remains in the buffers.
    Specified by:
      `flushNonBlocking` in class `SocketWrapperBase<NioChannel>`
    Returns:
      `true` if data remains to be flushed after this method completes, otherwise `false`.
    Throws:
      `IOException` - If an IO error occurs during the write

  - ### doWrite

    protected void doWrite(boolean block, ByteBuffer buffer) throws IOException
    Description copied from class: `SocketWrapperBase`
    Write the contents of the ByteBuffer to the socket. For blocking writes either then entire contents of the buffer will be written or an IOException will be thrown. Partial blocking writes will not occur.
    Specified by:
      `doWrite` in class `SocketWrapperBase<NioChannel>`
    Parameters:
      `block` - Should the write be blocking or not?
      `buffer` - the ByteBuffer containing the data to be written
    Throws:
      `IOException` - If an I/O error such as a timeout occurs during the write

  - ### registerReadInterest

    public void registerReadInterest()
    Specified by:
      `registerReadInterest` in class `SocketWrapperBase<NioChannel>`

  - ### registerWriteInterest

    public void registerWriteInterest()
    Specified by:
      `registerWriteInterest` in class `SocketWrapperBase<NioChannel>`

  - ### createSendfileData

    public SendfileDataBase createSendfileData(String filename, long pos, long length)
    Specified by:
      `createSendfileData` in class `SocketWrapperBase<NioChannel>`

  - ### processSendfile

    public SendfileState processSendfile(SendfileDataBase sendfileData)
    Description copied from class: `SocketWrapperBase`
    Starts the sendfile process. It is expected that if the sendfile process does not complete during this call and does not report an error, that the caller will not add the socket to the poller (or equivalent). That is the responsibility of this method.
    Specified by:
      `processSendfile` in class `SocketWrapperBase<NioChannel>`
    Parameters:
      `sendfileData` - Data representing the file to send
    Returns:
      The state of the sendfile process after the first write.

    Specified by:
      `populateRemoteAddr` in class `SocketWrapperBase<NioChannel>`

  - ### populateRemoteHost

    protected void populateRemoteHost()
    Specified by:
      `populateRemoteHost` in class `SocketWrapperBase<NioChannel>`

  - ### populateRemotePort

    protected void populateRemotePort()
    Specified by:
      `populateRemotePort` in class `SocketWrapperBase<NioChannel>`

  - ### populateLocalName

    protected void populateLocalName()
    Specified by:
      `populateLocalName` in class `SocketWrapperBase<NioChannel>`

      `populateLocalPort` in class `SocketWrapperBase<NioChannel>`

  - ### getSslSupport

    Description copied from class: `SocketWrapperBase`
    Obtain an SSLSupport instance for this socket.
    Specified by:
      `getSslSupport` in class `SocketWrapperBase<NioChannel>`
    Returns:
      An SSLSupport instance for this socket.

  - ### doClientAuth

    public void doClientAuth(SSLSupport sslSupport) throws IOException
    Description copied from class: `SocketWrapperBase`
    Require the client to perform CLIENT-CERT authentication if it hasn't already done so.
    Specified by:
      `doClientAuth` in class `SocketWrapperBase<NioChannel>`
    Parameters:
      `sslSupport` - The SSL/TLS support instance currently being used by the connection that may need updating after the client authentication
    Throws:
      `IOException` - If authentication is required then there will be I/O with the client and this exception will be thrown if that goes wrong

  - ### setAppReadBufHandler

    Specified by:
      `setAppReadBufHandler` in class `SocketWrapperBase<NioChannel>`

  - ### newOperationState
