and update()
; implement ObjectProcessorSelectColumn

Milestone
We'd like to be able to allow a single
SelectColumn
to produce multiple outputs. This is a step towards tuple-UDF support, but also will enableObjectProcessor
to be used as the backing system for aSelectColumn
, possibly with some refactorings.SelectColumn
to refactor member functions describing the output (name, type, etc) to aList<ColumnDefinition>
SelectColumn
to supportList<ChunkSource>
instead ofColumnSource
forgetDataView()
and probablygetLazyView()
.QueryTable
orSelectOrUpdateListener
to accommodate same.SelectColumnLayer
to be aware of multi-outputSelectColumns
and retrieve them together. Will probably need to useSharedContext
to allow theChunkSources
to share their input/calculations.ObjectProcessorSelectColumn
as an initial use case.The text was updated successfully, but these errors were encountered:
