Enclosing class:

BytesRefsFromBinaryBlockLoader

public static class BytesRefsFromBinaryBlockLoader.BytesRefsFromBinary
extends BytesRefsFromCustomBinaryBlockLoader.AbstractBytesRefsFromBinary

Read BinaryDocValues with no additional structure in the BytesRefs. Each BytesRef from the doc values maps directly to a value in the block loader.

Method Details

read

public BlockLoader.Block read(BlockLoader.BlockFactory factory,
 BlockLoader.Docs docs,
 int offset,
 boolean nullsFiltered)
                       throws IOException

Description copied from interface: BlockLoader.ColumnAtATimeReader

Reads the values of all documents in docs.

Specified by:

read in interface BlockLoader.ColumnAtATimeReader

Overrides:

read in class BytesRefsFromCustomBinaryBlockLoader.AbstractBytesRefsFromBinary

Parameters:

nullsFiltered - if true, then target docs are guaranteed to have a value for the field; otherwise, the guarantee is unknown. This enables optimizations for block loaders, treating the field as dense (every document has value) even if it is sparse in the index. For example, "FROM index | WHERE x != null | STATS sum(x)", after filtering out documents without value for field x, all target documents returned from the source operator will have a value for field x whether x is dense or sparse in the index.

Throws:

IOException

read

public void read(int doc,
 BlockLoader.BytesRefBuilder builder)
          throws IOException

Specified by:

read in class BytesRefsFromCustomBinaryBlockLoader.AbstractBytesRefsFromBinary

Throws:

IOException

toString

public String toString()

Description copied from interface: BlockLoader.Reader

A string representation of the BlockLoader.Reader. It's important that this have a nice implementation because this is used in the profile.

Specified by:

toString in interface BlockLoader.Reader

Specified by:

toString in class BlockDocValuesReader
