- All Implemented Interfaces:
- org.apache.avalon.framework.component.Component, org.xml.sax.ContentHandler, org.xml.sax.ext.LexicalHandler, org.apache.avalon.framework.logger.Loggable, org.apache.avalon.excalibur.pool.Poolable, org.apache.avalon.excalibur.pool.Recyclable, SitemapModelComponent, Transformer, XMLConsumer, XMLPipe, XMLProducer
- public class FilterTransformer
- extends AbstractTransformer
- implements org.apache.avalon.excalibur.pool.Poolable
The filter transformer can be used to let only an amount of elements through in
a given block.
Usage in sitemap
<map:transform type="filter">
<map:parameter name="element-name" value="row"/>
<map:parameter name="count" value="5"/>
<map:parameter name="blocknr" value="3"/>
</map:transform>
Only the 3th block will be shown, containing only 5 row elements.
