Examples with IndexParams org.apache.jena.tdb.index.IndexParams used on opensource projects

Example 1 with IndexParams

use of org.apache.jena.tdb.index.IndexParams in project jena by apache.

the class IndexAssembler method open.

@Override
public TupleIndex open(Assembler a, Resource root, Mode mode) {
    exactlyOneProperty(root, pDescription);
    String desc = getAsStringValue(root, pDescription).toUpperCase(Locale.ENGLISH);
    exactlyOneProperty(root, pFile);
    String filename = getAsStringValue(root, pFile);
    // Need to get location from the enclosing PGraphAssembler
    if (location != null)
        filename = location.absolute(filename);
    String primary = null;
    RecordFactory rf = null;
    switch(desc.length()) {
        case 3:
            primary = Names.primaryIndexTriples;
            rf = SystemTDB.indexRecordTripleFactory;
            break;
        case 4:
            primary = Names.primaryIndexQuads;
            rf = SystemTDB.indexRecordQuadFactory;
            break;
        default:
            throw new TDBException("Bad length for index description: " + desc);
    }
    // Problems with spotting the index technology.
    // FileSet.fromFilename(filename) ;
    FileSet fileset = null;
    IndexParams idxParams = StoreParams.getDftStoreParams();
    RangeIndex rIndex = IndexFactory.buildRangeIndex(fileset, rf, idxParams);
    return new TupleIndexRecord(desc.length(), new ColumnMap(primary, desc), desc, rf, rIndex);
}

Example 2 with IndexParams

use of org.apache.jena.tdb.index.IndexParams in project jena by apache.

the class TestTupleIndexRecord method createIndex.

@Override
protected TupleIndexRecord createIndex(String description) {
    IndexParams indexParams = StoreParams.getDftStoreParams();
    RangeIndex rIdx = IndexFactory.buildRangeIndex(FileSet.mem(), factory, indexParams);
    ColumnMap cmap = new ColumnMap("SPO", description);
    TupleIndexRecord index = new TupleIndexRecord(3, cmap, description, factory, rIdx);
    return index;
}

Example 3 with IndexParams

use of org.apache.jena.tdb.index.IndexParams in project jena by apache.

the class TestTupleIndexRecordDirect method create.

static TupleIndexRecord create(String description) {
    IndexParams indexParams = StoreParams.getDftStoreParams();
    RangeIndex rIdx = IndexFactory.buildRangeIndex(FileSet.mem(), factory, indexParams);
    ColumnMap cmap = new ColumnMap("SPO", description);
    TupleIndexRecord index = new TupleIndexRecord(3, cmap, description, factory, rIdx);
    return index;
