RCodeSelector

Description

RCodeSelector is a selector in which files can be selected based on CRC or MD5 comparison in source and target directories. Files are removed of the fileset if and only if their CRC or MD5 are identical.

Parameters

Attribute	Description	Default value
dir †	The base directory to look for the files to compare against. The precise location depends on a combination of this attribute and the <mapper> element, if any.	No default value
lib †	The procedure library to look for the files to compare against.	No default value
mode	Use MD5 or CRC to compare r-code	CRC

† Only one of those attributes is mandatory ‡ Mandatory attribute

Parameters as nested elements

None

Examples

<!-- Don't forget to include types definition -->
<typedef resource="types.properties" />

<target name="copy">
  <copy todir="destDir" includeEmptyDirs="false">
    <fileset dir="sourceDir1" includes="**/*.r">
      <RCodeSelector dir="sourceDir2" mode="md5" />
    </fileset>
  </copy>
</target>
</pre>

Will copy all .r files from sourceDir1 to destDir, excluding any r-code whose MD5 is identical in sourceDir1 and sourceDir2

Notes

If you have IOException (usually with additional message Resetting to invalid mark), then you can increase the buffer size for RCodeInfo class by defining the Java property rcodeinfo.buffer_size. On the command line, this is done with:

set JAVA_OPTS=-Drcodeinfo.buffer_size=132000
ant target_name_here

Default size is 65536.
