Hi all, FUNCTOR-30 [1] contains a patch for [functor] that I'd like to merge. I will spend one or two other days reviewing the code style & tests, and will wait till the middle of the week before merging, so that others can take some time to review too. The patch provides several predicates to use with Strings, such as IsNull, IsAlpha, IsAlphanumeric, etc. Most of them calling existing methods in [lang]'s StringUtils.
All the best,Bruno [1] https://issues.apache.org/jira/browse/FUNCTOR-30
