Method Detail

index

void index(int capacity,
         Iterator<BigdataValue> valuesIterator)

Add the terms to the full text index so that we can do fast lookup of the corresponding term identifiers. Only literals are tokenized. Literals that have a language code property are parsed using a tokenizer appropriate for the specified language family. Other literals and URIs are tokenized using the default Locale.

Parameters:

capacity - A hint to the underlying layer about the buffer size before an incremental flush of the index.

itr - Iterator visiting the terms to be indexed.
