Raymond commented on NIFI-1988:
-------------------------------
Another possibility is to put the filter options in a separate property "Filter
strategy" with a combobox as value (Example values: Regex, Exact, Contains,
Prefix, Suffix, File extension etc)

> Key: NIFI-1988
> URL: https://issues.apache.org/jira/browse/NIFI-1988
> Project: Apache NiFi
> Issue Type: Wish
> Components: Extensions
> Affects Versions: 1.0.0
> Environment: Windows
> Reporter: Raymond
> Priority: Minor
>
> File Filter on the GetFile processor accepts a regular expression (Java
> Regex). As not all developers use Java/Regex it would nice to give other
> file filter options as well, like filename exact, contains, prefix and
> suffix.
> For example the file "helloworld.txt" would be picked up if:
> filename_exact --> helloworld.txt
> filename_contains --> helloworld.txt, ello, d.txt
> filename_prefix --> hello, helloworld
> filename_suffix --> .txt, txt, world.txt
> I don't know if this is current possible, but it would be nice to add this as
> a combobox on top of the value field (regex, exact, contains, prefix, suffix).
> Underneath the filter could still be a regular expression (if other filters
> would slow down the pick up process).
