<H1>OutOfDate</H1>
Task definition for the <CODE>outofdate</CODE> task. This is an
extension of uptodate which allows multible targets and contains an
embedded &lt;parallel&gt; or &lt;sequential&gt; element. If any of
the target file's dates are earlier than any of the source file's
dates, then the specified &lt;parallel&gt; or &lt;sequential&gt;
block is executed. The task may also contain mappers to map source
files to corresponding target files.

</TABLE>
<H2>Attributes specified as nested elements</H2>

sourcefiles - The list of files which are source files.
This element is required.
 targetfiles - The list of
files which are target files. 

Both of these nested elements are <A HREF="http://ant.apache.org/manual/using.html#path">Path</A>
elements which are are used to select sets or lists of files or
directories
 The sourcefiles may contain no files. In this case, outofdate will
 check the existance of the targetfiles.
mapper – This is used to map source files to target
files.
As well as the regular attributes for mapper, there is a extra attribute to specify
 the relative directory of the sources.
 <table cellspacing="0" cellpadding="2" border="1">
 <tr>
 <td valign="top">Attribute</td>
 <td valign="top">Description</td>
 <td valign="top">Required</td>
 </tr>
 <tr>
 <td valign="top">dir</td>
 <td valign="top">
 The directory to the sources are relative to for the mapper.
 Default is ${base.dir}.
 </td>
 <td valign="top">No</td>
 </tr>
 </table>
 
There may be a number of mapper nested elements. 
deletetargets – This is used to delete targets if the
corresponding sources are outofdate.

 <table cellspacing="0" cellpadding="2" border="1">
 <tr>
 <td valign="top">Attribute</td>
 <td valign="top">Description</td>
 <td valign="top">Required</td>
 </tr>
 <tr>
 <td valign="top">all</td>
 <td valign="top">
 Whether to delete all the targets ("true"/"false"). Defaults to
 "false".
 </td>
 <td valign="top">No</td>
 </tr>
 <tr>
 <td valign="top">quiet</td>
 <td valign="top">
 Do not display diagnostic messages when deleting targets
 ("true"/ "false"). Defaults to false.
 When set to "true", if a file or directory cannot be deleted,
 no error is reported. This setting emulates the -f option to
 the Unix rm command. Default is "false".
 Setting this to "true" implies setting failonerror to "false"
 </td>
 <td valign="top">No</td>
 </tr>
 <tr>
 <td valign="top">failonerror</td>
 <td valign="top">
 Controls whether an error (such as a failure to delete a file)
 stops the build or is merely reported to the screen.
 Only relevant if quiet is &quot;false&quot;.
 Default is &quot;true&quot;.
 Controls whether a failure to delete a target stops
 the build or is merely reported to the screen.
 </td>
 <td valign="top">No</td>

<H2>Examples</H2>
The following example creates the file ${jrun.file} if is older
that build.xml, or any file in ${lib.dir}.
<PRE> &lt;outofdate&gt;
 &lt;sourcefiles&gt;
 &lt;pathelement path="build.xml"/&gt;
 &lt;fileset dir="${lib.dir}"/&gt;
 &lt;/sourcefiles&gt;
 &lt;targetfiles path="${jrun.file}"/&gt;
 &lt;sequential&gt;
 &lt;mkdir dir=&quot;${build.bin.dir}&quot;/&gt;
 &lt;echo file=&quot;${jrun.file}&quot; message=&quot;java -cp ${jrun.path} $*&quot;/&gt;
 &lt;chmod file=&quot;${jrun.file}&quot; perm=&quot;ugo+rx&quot;/&gt;
 &lt;/sequential&gt;
 &lt;/outofdate&gt; </PRE>
The following example check the generated files, MODULE.IDS,
acme_agent_mib.h, acme_agent_mib.cpp are older that miblist.txt, or
any file in ${mib.src}, and if so an embedded shellScript is invoked
to update the files.
<PRE> &lt;outofdate&gt;
 &lt;sourcefiles&gt;
 &lt;pathelement path=&quot;${agent.src}/miblist.txt&quot;/&gt;
 &lt;fileset dir=&quot;${mib.src}&quot;/&gt;
 &lt;/sourcefiles&gt;
 &lt;targetfiles&gt;
 &lt;pathelement path=&quot;${rep}/MODULE.IDS&quot;/&gt;
 &lt;pathelement path=&quot;${gen-agent}/acme_agent_mib.h&quot;/&gt;
 &lt;pathelement path=&quot;${gen-agent}/acme_agent_mib.cpp&quot;/&gt;
 &lt;/targetfiles&gt;
 &lt;sequential&gt;
 &lt;shellscript shell=&quot;bash&quot; dir=&quot;${agent.src}&quot;&gt;
 classname=com.agentpp.agentgen.AgentGenConsole
 h1=${gen-agent}/acme_agent_mib.x
 ag() {
 java -cp ${lib.dir}/agentgen.jar $classname ${rep} $@
 }
 ag initialize
 ag load miblist.txt
 ag generate ACME-AGENT-MIB h &gt; $h1
 (head -16 $h1; echo &quot;using namespace Agentpp;&quot;;
 tail +16 $h1) &gt; ${gen-agent}/acme_agent_mib.h
 ag generate ACME-AGENT-MIB c &gt;\
 ${gen-agent}/acme_agent_mib.cpp
 &lt;/shellscript&gt;
 &lt;/sequential&gt;
 &lt;/outofdate&gt;</PRE>
The following example sets the project manual.outofdate if any
of the xml files are newer than index.html, or if any of the xml
files are newer than their corresponding .html file. A path
identified by sources.path, is created which contains the
sources that fullfilled these conditions.
<PRE>
 &lt;outofdate property="manual.outofdate" outputsourcespath="sources.path"&gt;
 &lt;sourcefiles&gt;
 &lt;fileset dir="${src.manual}" includes="**/*.xml"/&gt;
 &lt;/sourcefiles&gt;
 &lt;targetfiles path="${doc.manual}/index.html"/&gt;
 &lt;mapper type="glob" dir="${src.manual}" from="*.xml" to="${doc.manual}/*.html"/&gt;
 &lt;/outofdate&gt;
</PRE>

The following assumes that there is a program called gengrammer
that takes a grammer file as an input and generates a .h and a .c
file in the current directory.
<PRE>
 &lt;outofdate property="manual.outofdate"
 outputsources="grammer.sources"&gt;
 &lt;sourcefiles&gt;
 &lt;fileset dir="${src.grammer}" includes="**/*.y"/&gt;
 &lt;/sourcefiles&gt;
 &lt;mapper type="glob" dir="${src.grammer}" from="*.y" to="${gen.grammer}/*.c"/&gt;
 &lt;mapper type="glob" dir="${src.grammer}" from="*.y" to="${gen.grammer}/*.h"/&gt;
 &lt;sequential&gt;
 &lt;shellscript shell="bash"&gt;
 cd ${gen.grammer}
 for g in ${grammer.sources}
 do
 gengrammer $g
 done
 &lt;/shellscript&gt;
 &lt;/sequential&gt;
 &lt;/outofdate&gt;
