Item with maximum value or maximum value of function applied to items (FloatNamedArraylist, NamedArraylist, and UnicodeNamedArraylist classes)
[Introduced in Sirius Mods 7.8]
MaximumItem is related to the Maximum collection methods, which return the number or name of the item that has the maximum value in a collection.
Syntax
%item = anyNal:MaximumItem[( [itemFunction])]
Syntax terms
| %item | A collection item of the same type as the anyNal object. |
|---|---|
| anyNal | A NamedArraylist, FloatNamedArraylist, or UnicodeNamedArraylist object variable. |
| itemFunction | A function that operates on the type of the items in the collection. It may be a local method or method variable or a class member (Variable, Property), and it must return an intrinsic value. The default itemFunction value is the special identity function, This, which simply returns the item value. |
Usage notes
- The optional itemFunction parameter lets you further manipulate the collection item values before performing the MaximumItem method's item evaluation. The itemFunction default (identity function This) fails against non-intrinsic values, however. If your collection items are not intrinsic values, you must specify an itemFunction function that can map the item values to intrinsic values.
Examples
For the NamedArrayList %nal, Maximum returns the index (item name) of the item that has the maximum value, while MaximumItem returns the value of that item:
b %nal is namedArraylist of float %nal = new %nal('Chicago') = 22 %nal('New York') = -999 %nal('Los Angeles') = 3.1415926 %nal('Philadelphia') = 1099 printText {~=%nal:maximum} printText {~=%nal:maximumItem} end
The result is:
%nal:maximum=Philadelphia %nal:maximumItem=1099
