| <title>Augment Task</title> |
| </head> |
| |
| <body> |
| |
| <h2>Augment</h2> |
| <p><em>Since Apache Ant 1.8.1</em></p> |
| <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 <var>id</var> attribute, then treats the |
| declared <code>augment</code> element as though it were the original element.</p> |
| |
| <h3>Parameters</h3> |
| <table class="attr"> |
| <tr> |
| <th scope="col">Attribute</th> |
| <th scope="col">Description</th> |
| <th scope="col">Required</th> |
| </tr> |
| <tr> |
| <td>id</td> |
| <td>The <var>id</var> of the reference to augment. If no such reference has been declared |
| a <code>BuildException</code> is thrown.</td> |
| <td>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>Permissible nested elements are dependent on the reference to be modified.</p> |
| |
| <h3>Examples</h3> |
| |
| <p>Given</p> |
| |
| <pre><fileset id="input-fs" dir="${basedir}"/></pre> |
| |
| <p>invocation</p> |
| |
| <pre><augment id="input-fs" excludes="foo"/></pre> |
| |
| <p>modifies the <var>excludes</var> attribute of <samp>input-fs</samp>, whereas</p> |
| |
| <pre> |
| <augment id="input-fs"> |
| <filename name="bar"/> |
| </augment></pre> |
| |
| <p>adds a <code>filename</code> selector to <samp>input-fs</samp>.</p> |
