| * The <code>IsNotDistinctFromTransformFunction</code> extends <code>DistinctFromTransformFunction</code> to |
| * implement the IS_NOT_DISTINCT_FROM operator. |
| * |
| * The results are in boolean format and stored as an integer array with 1 represents true and 0 represents false. |
| * Expected result: |
| * NUll IS_NOT_DISTINCT_FROM Value: 0 |
| * NUll IS_NOT_DISTINCT_FROM Null: 1 |
| * ValueA IS_NOT_DISTINCT_FROM ValueB: EQUALS(ValueA, ValueB) |
| * |
| * Note this operator only takes column names for now. |
| * SQL Syntax: |
| * columnA IS_NOT_DISTINCT_FROM columnB |
| * |
| * Sample Usage: |
| * IS_NOT_DISTINCT_FROM(columnA, columnB) |
