Class IndexBuilderNode

java.lang.Object
  com.hp.hpl.jena.query.larq.IndexBuilderBase
      com.hp.hpl.jena.query.larq.IndexBuilderNode

All Implemented Interfaces:

IndexBuilder

public class IndexBuilderNode
extends IndexBuilderBase

Helper class for index creation from external content. Once completed, the index builder should be closed for writing, then the getIndex() called. To update the index once closed, the application should create a new index builder. Any index readers (e.g. IndexLARQ objects) need to be recreated and registered.
