public class TestColumnConverter
extends SubOperatorTest

Tests/demonstrates the generic form of the column/row format feature. Creates a mock source as a proxy for some reader-specific row source. Defines two column formats: one scalar, one array. Runs a simple scan inventing values for the mock converters to convert. Not really much to test, more a verification that the pattern works in practice.
