<a href="__builtin__.object-class.html"><code>object</code></a> --+

        <b>SFTPHandle</b>
</pre><br />

<hr/>

<p>Abstract object representing a handle to an open file (or folder) in 
an SFTP server implementation. Each handle has a string representation 
used by the client to refer to the underlying file.</p>
Server implementations can (and should) subclass SFTPHandle to 
implement features of a file handle, like <a 
href="paramiko.SFTPHandle-class.html#stat" 
class="link"><code>stat</code></a> or <a 
href="paramiko.SFTPHandle-class.html#chattr" 
class="link"><code>chattr</code></a>.

  <p>Write <code>data</code> into this file at position

  <code>self</code> named <code>writefile</code>, and if present, 
  performs the write operation on the python file-like object found

  make it easy to implement read-only (or write-only) files, but if both 
  attributes are present, they should refer to the same file.
