Class AbstractColumnData<EffectiveType, UnderlyingType, ColumnDataType>

The AbstractColumnData<DataType, ColumnDataType> object provides access to data associated with a particular Deephaven table column. Both Deephaven.OpenAPI.Client.Internal.TableData and ITableUpdate objects use this abstraction to provide access to table data resulting from one-time requests or subscription updates, respectively.

Each concrete column type is represented by a subclass of this type. Depending on the column type, a different subset of "getter" methods is implemented.
