| |
| <p>This utility class allows for the logic to be reused in different scenarios where input |
| validation is done at different times either in org.apache.iceberg.transforms.Truncate and within |
| defined SQL functions for different compute engines for usage in SQL. |
| |
| <p>In general, the inputs to the functions should have already been validated by the calling |
| code, as different classes use truncate with different preprocessing. This generally means that |
| the truncation width is positive and the value to truncate is non-null. |
| |
| <p>Thus, <b>none</b> of these utility functions validate their input. <i>It is the responsibility |
| of the calling code to validate input.</i> |
