| <div class="block">Provides a set of tools to work with row sets when creating operator |
| and "sub-operator" unit tests. A row set is a batch of Drill vectors, |
| often called a "record batch." However, a record batch, in Drill, means |
| not just the data, but also an operator on that data. The classes |
| here work with the data itself, and can be used to test implementations |
| of things such as code generated classes and so on. |
| <p> |
| Drill defines a variety of record batch semantics, modeled here as |
| distinct row set classes: |
| <dl> |
| <dt>RowSetComparison</dt> |
| <dd>Used in tests to compare an "actual" row set against an "expected" |
| row set. Does a complete check of row counts, types and values. If values |
| are arrays (repeated), does a check of the entire array. Uses JUnit assertions |
| to report comparison failures.</dd></div> |
