This is the read-only version of a MIME body. There are only methods
to read the body contents.
<p>
The value of the body can be returned either as <code class="code">string</code>, or as
object channel. Both ways are possible independently of where
the value is stored, in-memory, or as external file.<br>
</div>
<hr width="100%">
<pre><span id="METHODvalue"><span class="keyword">method</span> value</span> : <code class="type">string</code></pre><div class="info">
The <code class="code">value</code> method returns the _decoded_ body,
i.e. transfer encodings are removed before the value is passed
back.
<p>
When the body is stored in an external file, this method
reads the complete file into memory.<br>
</div>
<pre><span id="METHODstore"><span class="keyword">method</span> store</span> : <code class="type"><a href="Netmime.html#TYPEstore">store</a></code></pre><div class="info">

Opens the value for reading. This works independently of where
the body is stored. For example, to read the body line by line:
<pre class="codepre"><code class="code"> let ch = body # open_value_rd () in
try
while true do
let line = ch # input_line() in
... (* do something *)
done;
assert false; (* never reached *)
with
End_of_file ->
ch # close_in()
</code></pre>
<p>
As <code class="code">value</code>, this method returns the value in decoded form.
This method is quite economical with the resources, and takes
only as much memory as needed for the channel operations.<br>
</div>
<pre><span id="METHODfinalize"><span class="keyword">method</span> finalize</span> : <code class="type">unit -> unit</code></pre><div class="info">
After the body has been finalized, it cannot be accessed any longer.
External resources (files) are deallocated, if they are seen as
temporary.<br>
</div>
</body></html>
