FullTextIndexedDataset(ISparqlDataset, IFullTextIndexer)

Creates a new Full Text Indexed Dataset.

Declaration
public FullTextIndexedDataset(ISparqlDataset dataset, IFullTextIndexer indexer)
Parameters
Type Name Description
ISparqlDataset dataset

Dataset to wrap.
IFullTextIndexer indexer

Indexer to use.
