<h2>Augment</h2>
|
|
|
|
<h3>Description</h3>
|
|
<p>Modify an existing reference by adding nested elements or (re-)assigning properties
|
|
mapped as XML attributes. This is an unusual task that makes use of Ant's internal
|
|
processing mechanisms to reload a previously declared reference by means of the 'id'
|
|
attribute, then treats the declared <code>augment</code> element as though it were the
|
|
original element.
|
|
<b>Since Ant 1.8.1</b></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">id</td>
|
|
<td valign="top">The id of the reference to augment. If no such reference has
|
|
been declared a <code>BuildException</code> is generated.</td>
|
|
<td valign="top" align="center">Yes</td>
|
|
</tr>
|
|
</table>
|
|
<p>
|
|
Additional permissible attributes are dependent on the reference to be modified.
|
|
</p>
|
|
|
|
<h3>Parameters specified as nested elements</h3>
|
|
|
|
<p>
