ListRangeExtractor
Extracts the minimum and maximum values found in a list.
例如, if this feature enters this transformer:
somelist{0}.val = 12
somelist{1}.val = 0.5
somelist{2}.val = 8
Then the value assigned to the resulting minimum attribute would be 0.5 and the value assigned to the maximum attribute would be 12.
Note that non-numeric minima and maxima may also be extracted.例如, if this feature enters this transformer:
somelist{0}.val = 'apple'
somelist{1}.val = 'donut'
somelist{2}.val = 'aardvark'
Then the value assigned to the resulting minimum attribute would be 'aardvark' and the value assigned to the maximum attribute would be 'donut'.
If some values are numeric and some are not, the minimum and maximum values extracted may not be useful.
