Class DefaultTopicMapIndexer

java.lang.Object
  net.ontopia.infoset.fulltext.topicmaps.DefaultTopicMapIndexer

public class DefaultTopicMapIndexer
extends java.lang.Object

INTERNAL: The default topic map indexer manager. This indexer is preconfigured in a way that it should be suitable for most cases when topic maps need to be indexed.

If external resources is not to be indexed the DefaultIndexerManager indexer manager is used internally, otherwise the following configuration:

• Uses the default ThreadedIndexerManager internally, except that it has its document processor timeout set to 30 seconds.
• The document processor configuration is a document preloader that downloads external resources and stores them in the "contents" field.
• Uses the DefaultTopicMapDocumentGenerator to generate DocumentIFs for the topic map objects.
