Examples of org.apache.xindice.core.indexer.Indexer

org.apache.xindice.core.indexer.Indexer
Indexer is the abstract indexing interface for Xindice. An Indexer object is implemented in order to retrieve and manage indexes.

Any number of Indexer instances may be associated with a single Collection. The type of Indexer utilized by a query depends on the 'Style' of Indexer and the type of QueryResolver that is being used to performt he query. Currently, Xindice only internally supports one kind of Indexer: 'XPath'.
