@NotThreadSafe
public class ModeShapeConfiguration
extends Object

A configuration builder for a ModeShapeEngine. This class is an internal domain-specific language (DSL), and is designed to be used in a traditional way or in a method-chained manner:

 configuration.repositorySource("Source1").setClass(InMemoryRepositorySource.class).setDescription("description");
 configuration.mimeTypeDetector("detector").setClass(ExtensionBasedMimeTypeDetector.class).setDescription("default detector");
 configuration.sequencer("MicrosoftDocs")
              .setClass("org.modeshape.sequencer.msoffice.MSOfficeMetadataSequencer")
              .setDescription("Our primary sequencer for all .doc files")
              .sequencingFrom("/public//(*.(doc|xml|ppt)[*]/jcr:content[@jcr:data]")
              .andOutputtingTo("/documents/$1");
 configuration.save();
