Description copied from interface: BlockLoader.OptionalColumnAtATimeReader

Attempts to read the values of all documents in docs Returns null if unable to load the values.

Specified by:

tryRead in interface BlockLoader.OptionalColumnAtATimeReader

Parameters:

nullsFiltered - if true, then target docs are guaranteed to have a value for the field. see BlockLoader.ColumnAtATimeReader.read(BlockFactory, Docs, int, boolean)

toDouble - a function to convert long values to double, or null if no conversion is needed/supported

toInt - whether to convert to int in case int block / vector is needed

binaryMultiValuedFormat - whether the multi-valued binary format is used (CustomBinaryDocValuesField).

Throws:

IOException
