Example 28 with TupleIndex

use of org.apache.jena.tdb.store.tupletable.TupleIndex in project jena by apache.

the class SetupTDB method makeTupleIndex.

public static TupleIndex makeTupleIndex(Location location, String primary, String indexOrder, String indexName, int keyLength) {
    FileSet fs = new FileSet(location, indexName);
    int readCacheSize = params.getBlockReadCacheSize();
