Class StringFunctions

java.lang.Object
io.trino.operator.scalar.StringFunctions
public final class StringFunctions extends Object
Current implementation is based on code points from Unicode and does ignore grapheme cluster boundaries. Therefore only some methods work correctly with grapheme cluster boundaries.
