Class WildcardSchemaProjection


public class WildcardSchemaProjection extends ReaderLevelProjection
Perform a wildcard projection with an associated output schema. Matches the reader schema against the output schema. If a column appears, it is projected into the output schema. If not found, then a null column (as defined by the output schema) is projected.

Note that we don't go down this path for strict schema: in that case we expanded the columns at the scan level.
