## org.exist.cocoon
Class XMLDBSourceFactory

    java.lang.Object
      org.apache.avalon.framework.logger.AbstractLogEnabled
          org.exist.cocoon.XMLDBSourceFactory

All Implemented Interfaces:
  org.apache.avalon.framework.component.Component, org.apache.avalon.framework.configuration.Configurable, org.apache.avalon.framework.logger.LogEnabled, org.apache.excalibur.source.SourceFactory, org.apache.avalon.framework.thread.ThreadSafe

public final class XMLDBSourceFactory
extends org.apache.avalon.framework.logger.AbstractLogEnabled
implements org.apache.excalibur.source.SourceFactory, org.apache.avalon.framework.configuration.Configurable, org.apache.avalon.framework.thread.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.exist.cocoon.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.

This class is an import of Cocoon trunk XMLDBSourceFactory, to ensure connexion with a modified XMLDBSource.
