java.lang.Object

org.elasticsearch.index.mapper.blockloader.docvalues.BlockDocValuesReader.DocValuesBlockLoader

org.elasticsearch.index.mapper.AbstractShapeGeometryFieldMapper.AbstractShapeGeometryFieldType.BoundsAndCentroidBlockLoader

All Implemented Interfaces:

BlockLoader

Enclosing class:

AbstractShapeGeometryFieldMapper.AbstractShapeGeometryFieldType<T>

protected static class AbstractShapeGeometryFieldMapper.AbstractShapeGeometryFieldType.BoundsAndCentroidBlockLoader
extends BlockDocValuesReader.DocValuesBlockLoader

Block loader for extracting both bounds and centroid data from shape doc values. The default implementation outputs 10 doubles per document for geo shapes: [top, bottom, negLeft, negRight, posLeft, posRight, centroidX, centroidY, weight, shapeTypeOrdinal] Subclasses can override writeBounds() for different bounds formats (e.g., cartesian uses 4 values).

Method Details

reader

public BlockLoader.ColumnAtATimeReader reader(CircuitBreaker breaker,
 org.apache.lucene.index.LeafReaderContext context)
                                       throws IOException

Specified by:

reader in class BlockDocValuesReader.DocValuesBlockLoader

Throws:

IOException

builder

public BlockLoader.Builder builder(BlockLoader.BlockFactory factory,
 int expectedCount)

Description copied from interface: BlockLoader

The BlockLoader.Builder for data of this type. Called when loading from a multi-segment or unsorted block.

writeBounds

protected void writeBounds(BlockLoader.DoubleBuilder builder,
 Extent extent)

Writes the bounds portion of the combined output. Default implementation writes 6 values for geo shapes: [top, bottom, negLeft, negRight, posLeft, posRight]. Subclasses can override for different formats (e.g., cartesian uses 4 values).
