[jira] [Updated] (NIFI-6502) add padLeft() and padRight() functions
to RecordPath
[ https://issues.apache.org/jira/browse/NIFI-6502?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Alessandro D'Armiento updated NIFI-6502:
----------------------------------------
Description:
h2. Current Situation
- [Record path functions|https://nifi.apache.org/docs/nifi-docs/html/record-path-guide.html#functions] don't provide anything to perform string padding
h1. Improvement Proposal
- Support two new recordPath functions
-- padLeft:
--- padLeft(string field, int desiredLength) will prepend a default character to the input string until it reaches the length desiredLength
--- padLeft(String field, int desiredLength, char c) will prepend the c characters to the input string until it reaches the length n
-- padRight:
--- padRight(string field, int desiredLength) will append a default character to the input string until it reaches the length desiredLength
--- padRight(String field, int desiredLength, char c) will append the c characters to the input string until it reaches the length n
-- Default character should be a renderable character such as underscore
-- If the input string is already longer than the padding length, no operation should be performed
h3. Examples
----
{
"name" : "john smith"
}
----
`padLeft(/name, 15, '@')` => @@@@@john smith
`padLeft(/name, 15)` => _____john smith
`padRight(/name, 15, '@')` => john smith@@@@@
`padRight(/name, 15)`=> john smith_____
