docs: This method should be used by code that wishes to wrapper a WsByteBuffer directly. This is
  usually in the case where data has been received. Using this method the buffer is
  automatically flipped so that data can immediately be read.
  <p>
  The JFapByteBuffer is automatically marked as read-only when calling this method.
  
  @param _buffer The data received from the JFap channel.
