7.2 Alias Objects 
</H2>

<P>
<dl><dt><b><a name="l2h-112"><tt class=member>data</tt></a></b>
<dd>
The raw data for the Alias record, suitable for storing in a resource
or transmitting to other programs.
</dl>

<P>
<dl><dt><b><a name="l2h-113"><tt class=method>Resolve</tt></a></b> (<big>[</big><var>file</var><big>]</big>)
<dd>
Resolve the alias. If the alias was created as a relative alias you
should pass the file relative to which it is. Return the FSSpec for
the file pointed to and a flag indicating whether the Alias object
itself was modified during the search process. If the file does
not exist but the path leading up to it does exist a valid fsspec
is returned.
</dl>

<P>
<dl><dt><b><a name="l2h-114"><tt class=method>GetInfo</tt></a></b> (<var>num</var>)
<dd>
An interface to the C routine <tt class=cfunction>GetAliasInfo()</tt>.
</dl>

<P>
<dl><dt><b><a name="l2h-115"><tt class=method>Update</tt></a></b> (<var>file, </var><big>[</big><var>file2</var><big>]</big>)
<dd>
Update the alias to point to the <var>file</var> given. If <var>file2</var> is
present a relative alias will be created.
</dl>

<P>
Note that it is currently not possible to directly manipulate a
resource as an Alias object. Hence, after calling
<tt class=method>Update()</tt> or after <tt class=method>Resolve()</tt> indicates that the alias
has changed the Python program is responsible for getting the
<tt class=member>data</tt> value from the Alias object and modifying the
resource.
