Example 6 with DimensionIndexer

use of io.druid.segment.DimensionIndexer in project druid by druid-io.

the class IncrementalIndexAdapter method getBitmapIndex.

@Override
public IndexedInts getBitmapIndex(String dimension, int index) {
    DimensionAccessor accessor = accessors.get(dimension);
    if (accessor == null) {
        return EmptyIndexedInts.EMPTY_INDEXED_INTS;
    }
    ColumnCapabilities capabilities = accessor.dimensionDesc.getCapabilities();
    DimensionIndexer indexer = accessor.dimensionDesc.getIndexer();
    if (!capabilities.hasBitmapIndexes()) {
        return EmptyIndexedInts.EMPTY_INDEXED_INTS;
    }
    final int id = (Integer) indexer.getUnsortedEncodedValueFromSorted(index);
    if (id < 0 || id >= indexer.getCardinality()) {
        return EmptyIndexedInts.EMPTY_INDEXED_INTS;
    }
    MutableBitmap bitmapIndex = accessor.invertedIndexes[id];
    if (bitmapIndex == null) {
        return EmptyIndexedInts.EMPTY_INDEXED_INTS;
    }
    return new BitmapIndexedInts(bitmapIndex);
}
