<h1><a name="name">NAME</a></h1>
<p>Apache::*::Table - Table classes for Apache::Request, Apache::Upload, and Apache::Cookie.</p>
<p>
</p>
<hr />
<h1><a name="synopsis">SYNOPSIS</a></h1>
<pre>
my $table = Apache::Request::Table->new($r);
$table->{test} = 1;
$table->{foo} = "bar1";
$table->add(foo => "bar2");</pre>
<pre>
{
my $do_data = "";
$table->do( sub { $do_data .= "@_,"; 1 } );
ok $do_data eq "test 1,foo bar1,foo bar2,";
}</pre>
<p>
</p>
<hr />
<h1><a name="description">DESCRIPTION</a></h1>
<p>This manpage documents the Apache::*::Table classes provided by the
Apache::Request, Apache::Upload, and Apache::Cookie modules. Table
classes are all derived from APR::Table, however since the underlying
values they contain are not simple character arrays, the <code>merge</code>, <code>compress</code>,
and <code>overlap</code> methods from APR::Table are not implemented.</p>
<p>
</p>
<hr />
<h1><a name="apache__request__table">Apache::Request::Table</a></h1>
<p>These tables arise as parameter tables generated by the <code>args</code>, <code>body</code>, and
<code>param</code> methods of Apache::Request. Their values are representable
by orinary perl scalars, but unlike APR::Table, the '\0' character may
be safely embedded in a value without truncating it.</p>
<pre>
my $table = Apache::Request::Table->new($r);
my $value = "bar\0quux";
$table->{foo} = $value;</pre>
<p>
</p>
<hr />
<h1><a name="apache__upload__table">Apache::Upload::Table</a></h1>
<p>These tables arise from the <code>Apache::Request::upload</code> method (which is
provided by Apache::Upload). Their values are Apache::Upload objects.</p>
<pre>
my $upload = Apache::Upload->new($r, name => "foo", file => __FILE__);
my $table = Apache::Upload::Table->new($r);
$table->add($upload);
$upload = $table->{foo};</pre>
<p>
</p>
<hr />
<h1><a name="apache__cookie__table">Apache::Cookie::Table</a></h1>
<p>These tables arise from the <code>cookies</code> method of Apache::Cookie::Jar, and
their values are Apache::Cookie objects (or Apache::Cookie derived objects-
see the discussion of <code>VALUE_CLASS</code> in <a href="group__apreq__xs__cookie.html">the Apache::Cookie manpage</a>).</p>
<pre>
my $cookie = Apache::Cookie->new($r, name =>"foo", value => "bar");
my $table = Apache::Cookie::Table->new($r);
$table->{foo} = $cookie;
$cookie = $table->{foo};</pre>
<p>
