<h2 id="propertyset">PropertySet</h2>
<p><em>Since Apache Ant 1.6</em></p>
<p>Groups a set of properties to be used by reference in a task that supports this.</p>
<table class="attr">
<tr>
<th scope="col">Attribute</th>
<th scope="col">Description</th>
<th scope="col">Required</th>
</tr>
<tr>
<td>dynamic</td>
<td>Whether to reevaluate the set every time the set is used.</td>
<td>No; default is <q>true</q></td>
</tr>
<tr>
<td>negate</td>
<td>Whether to negate results. If <q>true</q>, all properties <em>not</em> selected by
nested elements will be returned. <em>Since Ant 1.6.2</em>
</td>
<td>No; default is <q>false</q></td>
</tr>
</table>
<h3>Parameters specified as nested elements</h3>
<h4>propertyref</h4>
<p>Selects properties from the current project to be included in the set.</p>
<table class="attr">
<tr>
<th scope="col">Attribute</th>
<th scope="col">Description</th>
<th scope="col">Required</th>
</tr>
<tr>
<td>name</td>
<td>Select the property with the given name.</td>
<td rowspan="4">Exactly one of these</td>
</tr>
<tr>
<td>prefix</td>
<td class="left">Select the properties whose name starts with the given string.</td>
</tr>
<tr>
<td>regex</td>
<td class="left">Select the properties that match the given regular expression. Similar
to <a href="mapper.html#regexp-mapper">regexp type mappers</a>, this requires a supported
regular expression library.</td>
</tr>
<tr>
<td>builtin</td>
<td class="left">Selects a builtin set of properties. Valid values for this attribute
are <q>all</q> for all Ant properties, <q>system</q> for the system properties and
<q>commandline</q> for all properties specified on the
command line when invoking Ant (plus a number of special
internal Ant properties).</td>
</tr>
</table>
<h4>propertyset</h4>
<p>A <code>propertyset</code> can be used as the set union of
more <code>propertyset</code>s.</p>
<p>For example:</p>
<pre>
<propertyset id="properties-starting-with-foo">
<propertyref prefix="foo"/>
</propertyset>
<propertyset id="properties-starting-with-bar">
<propertyref prefix="bar"/>
</propertyset>
<propertyset id="my-set">
<propertyset refid="properties-starting-with-foo"/>
<propertyset refid="properties-starting-with-bar"/>
</propertyset>
</pre>
<p>collects all properties whose name starts with either <q>foo</q> or <q>bar</q> in the set
named <q>my-set</q>.</p>
<h4>mapper</h4>
<p>A <a href="mapper.html">mapper</a>—at maximum one mapper can be specified. The mapper
is used to change the names of the property keys, for example:
<pre>
<propertyset id="properties-starting-with-foo">
<propertyref prefix="foo"/>
<mapper type="glob" from="foo*" to="bar*"/>
</propertyset>
</pre>
<p>collects all properties whose name starts with <q>foo</q>, but changes the names to start
with <q>bar</q> instead.</p>
<p>If supplied, the nested mapper will be applied subsequent to any negation of matched
properties.</p>
