7.19.2 TarInfo Objects
</H2>
<P>
A <tt class="class">TarInfo</tt> object represents one member in a
<tt class="class">TarFile</tt>. Aside from storing all required attributes of a file
(like file type, size, time, permissions, owner etc.), it provides
some useful methods to determine its type. It does <em>not</em> contain
the file's data itself.
<P>
<tt class="class">TarInfo</tt> objects are returned by <tt class="class">TarFile</tt>'s methods
<tt class="method">getmember()</tt>, <tt class="method">getmembers()</tt> and <tt class="method">gettarinfo()</tt>.
<P>
<dl><dt><table cellpadding="0" cellspacing="0"><tr valign="baseline">

<td><var></var><big>[</big><var>name</var><big>]</big><var></var>)</td></tr></table></dt>
<dd>
Create a <tt class="class">TarInfo</tt> object.
</dl>
<P>
<dl><dt><table cellpadding="0" cellspacing="0"><tr valign="baseline">

<td><var></var>)</td></tr></table></dt>
<dd>
Create and return a <tt class="class">TarInfo</tt> object from a string buffer.
</dl>
<P>
<dl><dt><table cellpadding="0" cellspacing="0"><tr valign="baseline">

<td><var></var>)</td></tr></table></dt>
<dd>
Create a string buffer from a <tt class="class">TarInfo</tt> object.
</dl>
<P>
A <code>TarInfo</code> object has the following public data attributes:
<P>
<dl><dt><b><tt id='l2h-2921' xml:id='l2h-2921' class="member">name</tt></b></dt>
<dd>
Name of the archive member.
</dl>
<P>
<dl><dt><b><tt id='l2h-2922' xml:id='l2h-2922' class="member">size</tt></b></dt>
<dd>
Size in bytes.
</dl>
<P>
<dl><dt><b><tt id='l2h-2923' xml:id='l2h-2923' class="member">mtime</tt></b></dt>
<dd>
Time of last modification.
</dl>
<P>
<dl><dt><b><tt id='l2h-2924' xml:id='l2h-2924' class="member">mode</tt></b></dt>
<dd>
Permission bits.
</dl>
<P>
<dl><dt><b><tt id='l2h-2925' xml:id='l2h-2925' class="member">type</tt></b></dt>
<dd>
File type. <var>type</var> is usually one of these constants:
<tt class="constant">REGTYPE</tt>, <tt class="constant">AREGTYPE</tt>, <tt class="constant">LNKTYPE</tt>,
<tt class="constant">SYMTYPE</tt>, <tt class="constant">DIRTYPE</tt>, <tt class="constant">FIFOTYPE</tt>,
<tt class="constant">CONTTYPE</tt>, <tt class="constant">CHRTYPE</tt>, <tt class="constant">BLKTYPE</tt>,
<tt class="constant">GNUTYPE_SPARSE</tt>. To determine the type of a
<tt class="class">TarInfo</tt> object more conveniently, use the <code>is_*()</code>
methods below.
</dl>
<P>
<dl><dt><b><tt id='l2h-2926' xml:id='l2h-2926' class="member">linkname</tt></b></dt>
<dd>
Name of the target file name, which is only present in
<tt class="class">TarInfo</tt> objects of type <tt class="constant">LNKTYPE</tt> and
<tt class="constant">SYMTYPE</tt>.
</dl>
<P>
<dl><dt><b><tt id='l2h-2927' xml:id='l2h-2927' class="member">uid</tt></b></dt>

<P>
<dl><dt><b><tt id='l2h-2930' xml:id='l2h-2930' class="member">gname</tt></b></dt>
<dd>
Group name.
</dl>
<P>
A <tt class="class">TarInfo</tt> object also provides some convenient query methods:
<P>
<dl><dt><table cellpadding="0" cellspacing="0"><tr valign="baseline">
