| <h2><a name="patternset">PatternSet</a></h2> |
| <p><a href="../dirtasks.html#patterns">Patterns</a> can be grouped to |
| sets and later be referenced by their <code>id</code> attribute. They |
| are defined via a <code>patternset</code> element, which can appear |
| nested into a <a href="fileset.html">FileSet</a> or a directory-based |
| task that constitutes an implicit FileSet. In addition, |
| <code>patternset</code>s can be defined as a stand alone element at |
| the same level as <code>target</code> — i.e., as children of |
| <code>project</code> as well as as children of |
| <code>target</code>.</p> <p>Patterns can be specified by nested |
| <code><include></code>, or <code><exclude></code> elements |
| or the following attributes.</p> |
| <table border="1" cellpadding="2" cellspacing="0"> |
| <tr> |
| <td valign="top"><b>Attribute</b></td> |
| <td valign="top"><b>Description</b></td> |
| </tr> |
| <tr> |
| <td valign="top">includes</td> |
| <td valign="top">comma-separated list of patterns of files that must be |
| included. All files are included when omitted.</td> |
| </tr> |
| <tr> |
| <td valign="top">includesfile</td> |
| <td valign="top">the name of a file; each line of this file is |
| taken to be an include pattern. You can specify more than one |
| include file by using a nested includesfile elements.</td> |
| </tr> |
| <tr> |
| <td valign="top">excludes</td> |
| <td valign="top">comma-separated list of patterns of files that must be |
| excluded; no files (except default excludes) are excluded when omitted.</td> |
| </tr> |
| <tr> |
| <td valign="top">excludesfile</td> |
| <td valign="top">the name of a file; each line of this file is |
| taken to be an exclude pattern. You can specify more than one |
| exclude file by using a nested excludesfile elements.</td> |
| </tr> |
| </table> |
| <h3>Parameters specified as nested elements</h3> |
| <h4><code>include</code> and <code>exclude</code></h4> |
| <p>Each such element defines a single pattern for files to include or |
| exclude.</p> |
| <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 <a href="../dirtasks.html#patterns">pattern</a> |
| to in/exclude.</td> |
| <td align="center" valign="top">Yes</td> |
| </tr> |
| <tr> |
| <td valign="top">if</td> |
| <td valign="top">Only use this pattern if the named property is set.</td> |
| <td align="center" valign="top">No</td> |
| </tr> |
| <tr> |
| <td valign="top">unless</td> |
| <td valign="top">Only use this pattern if the named property is |
| <b>not</b> set.</td> |
| <td align="center" valign="top">No</td> |
| </tr> |
| </table> |
| <h4><code>includesfile</code> and <code>excludesfile</code></h4> |
| <p>If you want to list the files to include or exclude external to |
| your build file, you should use the includesfile/excludesfile |
| attributes or elements. Using the attribute, you can only specify a |
| single file of each type, while the nested elements can be specified |
| more than once - the nested elements also support if/unless attributes |
| you can use to test the existance of a property.</p> |
| <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 file holding the patterns to |
| in/exclude.</td> |
| <td align="center" valign="top">Yes</td> |
| </tr> |
| <tr> |
| <td valign="top">if</td> |
| <td valign="top">Only read this file if the named property is set.</td> |
| <td align="center" valign="top">No</td> |
| </tr> |
| <tr> |
| <td valign="top">unless</td> |
| <td valign="top">Only read this file if the named property is |
| <b>not</b> set.</td> |
| <td align="center" valign="top">No</td> |
| </tr> |

| <h3>Examples</h3> |
| <blockquote><pre> |
| <patternset id="non.test.sources" > |
| <include name="**/*.java"/> |
| <exclude name="**/*Test*"/> |
| </patternset> |
| </pre></blockquote> |
| <p>Builds a set of patterns that matches all <code>.java</code> files |
| that do not contain the text <code>Test</code> in their name. This set |
| can be <a href="../using.html#references">referred</a> to via |
| <code><patternset refid="non.test.sources"/></code>, |
| by tasks that support this feature, or by FileSets.</p> |
| <p>Note that while the <code>includes</code> and |
| <code>excludes</code> attributes accept |
| multiple elements separated by commas or spaces, the nested |
| <include> and <exclude> elements expect their name |
| attribute to hold a single pattern.</p> |
| <p>The nested elements allow you to use if and unless arguments to |
| specify that the element should only be used if a property is set, or |
| that it should be used only if a property is not set.</p> |
| <p>For example</p> |
| <blockquote><pre> |
| <patternset id="sources" > |
| <include name="std/**/*.java"/> |
| <include name="prof/**/*.java" if="professional"/> |
| <exclude name="**/*Test*"/> |
| </patternset> |
| </pre></blockquote> |
| <p>will only include the files in the sub-directory <em>prof</em> if the property |
| <em>professional</em> is set to some value.</p> |
| <p>The two sets</p> |
| <blockquote><pre> |
| <patternset includesfile="some-file" /> |
| </pre></blockquote> |
| <p>and</p> |
| <blockquote><pre> |
| <patternset> |
| <includesfile name="some-file" /> |
| <patternset/> |
| </pre></blockquote> |
| <p>are identical. The include patterns will be read from the file |
| <code>some-file</code>, one pattern per line.</p> |
| <blockquote><pre> |
| <patternset> |
| <includesfile name="some-file" /> |
| <includesfile name="${some-other-file}" |
| if="some-other-file" |
| /> |
| <patternset/> |
| </pre></blockquote> |
| <p>will also read include patterns from the file the property |
| <code>some-other-file</code> points to, if a property of that name has |
| been defined.</p> |
