All Implemented Interfaces:

org.apache.avalon.excalibur.pool.Poolable, org.apache.avalon.excalibur.pool.Recyclable, org.apache.cocoon.caching.CacheableProcessingComponent, org.apache.cocoon.sitemap.SitemapModelComponent, org.apache.cocoon.transformation.Transformer, org.apache.cocoon.xml.XMLPipe, org.apache.cocoon.xml.XMLProducer, org.apache.excalibur.xml.sax.XMLConsumer, ContentHandler, LexicalHandler

public class Include
extends org.apache.cocoon.transformation.AbstractTransformer
implements org.apache.cocoon.caching.CacheableProcessingComponent

The Include class reads an DRI XML file from and merges it into the existing document stream using the Wing framework. If the file is not present at the source provided a blank document is merged, allowing the pipeline to continue excecution. This is also logged as a warning.
