public class TruncateUtil
extends java.lang.Object
truncate transformations for various types.
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.
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.
Thus, none of these utility functions validate their input. It is the responsibility of the calling code to validate input.
See also UnicodeUtil.truncateString(CharSequence, int) and BinaryUtil.truncateBinaryUnsafe(ByteBuffer, int) for similar methods for Strings and
ByteBuffers.
