<h2><a name="resource">Resources</a></h2>
<p>
A file-like entity can be abstracted to the concept of a <i>resource</i>.
In addition to providing access to file-like attributes, a resource
implementation should, when possible, provide the means to read content
from and/or write content to the underlying entity. Although the resource
concept was introduced in <i>Ant 1.5.2</i>, resources are available for
explicit use beginning in <b>Ant 1.7</b>.
</p>

<h3>The built-in resource types are:</h3>

<ul>
<li><a href="#basic">resource</a> - a basic resource.</li>
<li><a href="#file">file</a> - a file.</li>
<li><a href="#zipentry">zipentry</a> - an entry in a zip file.</li>
<li><a href="#url">url</a> - a URL.</li>
<li><a href="#string">string</a> - a text string.</li>
<li><a href="#property">property</a> - an Ant property.</li>
</ul>

<h4><a name="basic">resource</a></h4>

<p>A basic resource. Other resource types derive from this basic
type; as such all its attributes are available, though in most cases
irrelevant attributes will be ignored. This and all resource
implementations are also usable as single-element
<a href="#collection">Resource Collections</a>.
</p>

<h2><a name="collection">Resource Collections</a></h2>
<p>
A Resource Collection is an abstraction of an entity that groups
together a number of <a href="#resource">resources</a>. Several of
Ant's "legacy" datatypes have been modified to behave as Resource Collections:
<ul>
<li><a href="fileset.html">fileset</a>,
<a href="dirset.html">dirset</a>,
<a href="filelist.html">filelist</a>, and
<a href="../using.html#path">path</a>
(and derivative types) expose <a href="#file">file</a> resources
</li>
<li><a href="zipfileset.html">zipfileset</a>
can expose <a href="#file">file</a> or <a href="#zipentry">zipentry</a>
resources depending on configuration
</li>
<li><a href="propertyset.html">propertyset</a>
exposes <a href="#property">property</a> resources
</li>
</ul>
</p>
<h3>The additional built-in resource collections are:</h3>
<ul>
<li><a href="#resources">resources</a> - generic resource collection</li>
<li><a href="#files">files</a> - collection of files similar to
<a href="fileset.html">fileset</a></li>
<li><a href="#restrict">restrict</a> - restrict a resource collection
to include only resources meeting specified criteria</li>
<li><a href="#sort">sort</a> - sorted resource collection</li>
<li><a href="#union">union</a> - set union of nested resource collections</li>
<li><a href="#intersect">intersect</a> - set intersection
of nested resource collections</li>
<li><a href="#difference">difference</a> - set difference
of nested resource collections</li>
</ul>
<h4><a name="resources">resources</a></h4>
<p>A generic resource collection, designed for use with
<a href="../using.html#references">references</a>.
For example, if a third-party Ant task generates a Resource Collection
of an unknown type, it can still be accessed via a
<code>&lt;resources&gt;</code> collection. The secondary use of this
collection type is as a container of other resource collections,
preserving the order of nested collections as well as
duplicate resources (contrast with <a href="#union">union</a>).
</p>

<h4><a name="files">files</a></h4>
<p>A group of files. These files are matched by <b>absolute</b> patterns
taken from a number of <a href="patternset.html">PatternSets</a>.
These can be specified as nested <code>&lt;patternset&gt;</code>
elements. In addition, <code>&lt;files&gt;</code> holds an implicit
PatternSet and supports the nested <code>&lt;include&gt;</code>,
<code>&lt;includesfile&gt;</code>, <code>&lt;exclude&gt;</code>
and <code>&lt;excludesfile&gt;</code> elements of PatternSet directly,
as well as PatternSet's attributes.
</p>
<p><a href="selectors.html">File Selectors</a> are available as nested
elements. A file must be selected by all selectors in order to be included;
<code>&lt;files&gt;</code> is thus equivalent to an
<code>&lt;and&gt;</code> file selector container.
</p>
<p><b>More simply put</b>, this type is equivalent to a
<a href="fileset.html">fileset</a> with no base directory.
<b>Please note</b> that without a base directory,
filesystem scanning is based entirely on include and exclude patterns.
A <a href="selectors.html#filenameselect">filename</a> (or any)
selector can <i>only</i> influence the scanning process <i>after</i>
the file has been included based on pattern-based selection.
</p>

</table>

<p><a name="symlink"><b>Note</b></a>: All files/directories for which
the canonical path is different from its path are considered symbolic
links. On Unix systems this usually means the file really is a
symbolic link but it may lead to false results on other
platforms.
</p>

<h4><a name="restrict">restrict</a></h4>
<p>Restricts another nested resource collection using resource selectors:
<blockquote>
<h4>Parameters specified as nested elements</h4>
<p>A single resource collection is required.</p>
<p>Nested resource selectors are used to "narrow down" the included
resources. These are patterned after <a href="selectors.html">file
selectors</a> but are, unsurprisingly, targeted to resources.
Several built-in resource selectors are available in the internal
<a href="antlib.html">antlib</a>
<code>org.apache.tools.ant.types.resources.selectors</code>:
</p>

<ul>
<li><a href="#rsel.name">name</a> - select resources by name.</li>
<li><a href="#rsel.exists">exists</a> - select existing resources.</li>
<li><a href="#rsel.date">date</a> - select resources by date.</li>
<li><a href="#rsel.type">type</a> - select resources by type.</li>
<li><a href="#rsel.size">size</a> - select resources by size.</li>
<li><a href="#rsel.instanceof">instanceof</a>
- select resources by class or Ant datatype.</li>
<li><a href="#rsel.and">and</a> - "and" nested resource selectors.</li>
<li><a href="#rsel.or">or</a> - "or" nested resource selectors.</li>
<li><a href="#rsel.not">not</a> - "not" a nested resource selector.</li>
<li><a href="#rsel.none">none</a>
- select resources selected by no nested resource selectors.</li>
<li><a href="#rsel.majority">majority</a> - select resources selected
by a majority of nested resource selectors.</li>

<h4><a name="sort">sort</a></h4>

<p>Sorts another nested resource collection according to the resources'
natural order, or by one or more nested resource comparators:</p>
<blockquote>
<h4>Parameters specified as nested elements</h4>
<p>A single resource collection is required.</p>
<p>The sort can be controlled and customized by specifying one or more
resource comparators. Resources can be sorted according to multiple
criteria; the first specified is the "outermost", while the last
specified is the "innermost". Several built-in resource comparators
are available in the internal <a href="antlib.html">antlib</a>
<code>org.apache.tools.ant.types.resources.comparators</code>:
</p>

<ul>
<li><a href="#rcmp.name">name</a> - sort resources by name</li>
<li><a href="#rcmp.exists">exists</a> - sort resources by existence</li>
<li><a href="#rcmp.date">date</a> - sort resources by date</li>
<li><a href="#rcmp.type">type</a> - sort resources by type</li>
<li><a href="#rcmp.size">size</a> - sort resources by size</li>
<li><a href="#rcmp.content">content</a> - sort resources by content</li>
<li><a href="#rcmp.reverse">reverse</a> - reverse the natural sort order,
or a single nested resource comparator</li>
</ul>

<h4><a name="rcmp.name">name</a></h4>
<p>Sort resources by name.</p>

<h4><a name="rcmp.exists">exists</a></h4>
<p>Sort resources by existence.
Not existing is considered "less than" existing.</p>

<h4><a name="rcmp.date">date</a></h4>
<p>Sort resources by date.</p>

<h4><a name="rcmp.type">type</a></h4>
<p>Sort resources by type (file or directory).
Because directories contain files, they are considered "greater".</p>

<h4><a name="rcmp.size">size</a></h4>
<p>Sort resources by size.</p>

<h4><a name="rcmp.content">content</a></h4>
<p>Sort resources by content.</p>
<table border="1" cellpadding="2" cellspacing="0">

<td valign="top"><b>Attribute</b></td>
<td valign="top"><b>Description</b></td>
<td align="center" valign="top"><b>Required</b></td>

<td valign="top">Whether content should be compared in binary mode.
If <i>false<i>, content will be compared without regard to
platform-specific line-ending conventions.</td>
<td valign="top">No, default <i>true</i></td>
</tr>
</table>

<h4><a name="rcmp.reverse">reverse</a></h4>
<p>Reverse the natural sort order, or a single nested comparator.</p>
