Package io.deephaven.engine.table.impl

Class PrecomputedRowSetBuilderRandom

java.lang.Object

io.deephaven.engine.table.impl.PrecomputedRowSetBuilderRandom

All Implemented Interfaces:

RowSetBuilderRandom

public class PrecomputedRowSetBuilderRandom
extends Object
implements RowSetBuilderRandom

This is a niche class that allows an existing rowset to masquerade as a RowSetBuilderRandom for the sake of efficient processing. General usage would embed this in a collection with actual RowSetBuilderRandom and process all items similarly. See PartitionByChunkedOperator.appendShifts(io.deephaven.chunk.LongChunk, io.deephaven.chunk.LongChunk, int, int, long) and PartitionByChunkedOperator.extractAndClearBuilderRandom(io.deephaven.chunk.WritableObjectChunk, int) for an example.
