Class XMLDBSourceFactory

java.lang.Object
  org.apache.avalon.framework.logger.AbstractLogEnabled
      org.apache.cocoon.components.source.impl.XMLDBSourceFactory

All Implemented Interfaces:

Configurable, LogEnabled, ThreadSafe, SourceFactory

public final class XMLDBSourceFactory
extends AbstractLogEnabled
implements SourceFactory, Configurable, ThreadSafe

This class implements the xmldb:// pseudo-protocol and allows to get XML content from an XML:DB enabled XML database.

The configuration of this protocol is as follows:

   <source-factory name="xmldb" src="org.apache.cocoon.components.source.impl.XMLDBSourceFactory>
     <driver type="foo" class="org.foomaker.FooXMLDBDriver"
             user="scott" password="tiger"
             collection="//localhost:8080/foo/base-path/"/>
     <driver...
   <source-factory>
 

The type attribute indicates the database type that will be used for URLs (e.g. xmldb:foo:/path/). The collection attribute specifies a base collection for paths that do not start with "//".

The returned sources are traversable, modifiable and xml-izable.
