Description
As per a discussion with mattyb149, an Expression Language function which allowed for a number of repetitions of a string would be useful for generating arbitrary random text in a GenerateFlowFile processor. The usage would be:
${"some string here":repeat(4)} # repeats the literal string 4 times
${literal("this_is_also_an_attribute_name"):repeat(3)} # repeats the literal string 3 times
${my_string_attr:repeat(5)} # repeats the value in the attribute 5 times
${"explicit string":repeat(random():mod(10):plus(1))} # repeats the string between 1 and 10 times
If it's easy to implement, I think a multiple parameter option would also be convenient, but it is not a requirement:
${"explicit string":repeat(random():mod(10):plus(1))} # repeats the string between 1 and 10 times
${"explicit string":repeat(1, 10)} # identical behavior to above
