<body>

<h2><a name="typedef">Typedef</a></h2>
<h3>Description</h3>
<p>Adds a data type definition to the current project, such that this
new type can be used in the current project. Two attributes are
needed, the name that identifies this data type uniquely, and the full
name of the class (including the packages) that implements this
type.</p>
<p>Typedef should be used to add your own types to the system. Data
types are things like <a href="../using.html#path">paths</a> or <a
href="../CoreTypes/fileset.html">filesets</a> that can be defined at
the project level and referenced via their ID attribute.</p>
<p>Custom data types usually need custom tasks to put them to good use.</p>
<h3>Parameters</h3>
<table border="1" cellpadding="2" cellspacing="0">
<tr>
<td valign="top"><b>Attribute</b></td>
<td valign="top"><b>Description</b></td>
<td align="center" valign="top"><b>Required</b></td>
</tr>
<tr>
<td valign="top">name</td>
<td valign="top">the name of the data type</td>
<td valign="top" align="center">Yes</td>
</tr>
<tr>
<td valign="top">classname</td>
<td valign="top">the full class name implementing the data type</td>
<td valign="top" align="center">Yes</td>
</tr>
<tr>
<td valign="top">classpath</td> <td valign="top">the classpath to
use when looking up <code>classname</code>.</td> <td
align="center" valign="top">No</td>
</tr>
</table>
<h3>Parameters specified as nested elements</h3>
<h4>classpath</h4>
<p><code>Typedef</code>'s <i>classpath</i> attribute is a
<a href="../using.html#path">PATH like structure</a> and can also be set
via a nested <i>classpath</i> element.</p>
<h3>Examples</h3>
<pre> &lt;typedef name=&quot;urlset&quot; classname=&quot;com.mydomain.URLSet&quot;/&gt;</pre>
<p>makes a data type called <code>urlset</code> available to Ant. The
class <code>com.mydomain.URLSet</code> implements this type.</p>
