Method lessThan

core/src/main/java/io/questdb/std/str/Utf8s.java:917–932

Strictly less than (<) comparison of two UTF8 sequences in lexicographical order. For example, for: l = aaaaa r = aaaaaaa the l < r will produce "true", however for: l = bbbb r = aaaaaaa the l < r will produce "false", because b < a. @param l left sequence, can be null @param r right se

     * @return if either l or r is "null", the return value false, otherwise sequences are compared lexicographically.
