matchItem

Implemented by: Object, Collection, Nil, Function

matchItem(item)

Object-matchItem

Test if item is identical to object.a = [1, 2, 3, "wort", "1", [pi, 2pi]]; a.any { |x| x.matchItem(3) }; // true a.any { |x| x.matchItem(5) }; // false a.any { |x| x.matchItem("wort") }; // false, because "wort" == "wort" but not identical.

Collection-matchItem

Test if item is included in collection.a = [1, 2, 3, "wort", "1", [pi, 2pi]]; a.any { |x| x.matchItem(pi) }; // true

Nil-matchItem

returns true (Nil serves as a "joker", a stand-in for anything).a = [nil, 1, 2, 3, "wort", "1", [pi, 2pi]]; a.any { |x| x.matchItem(10000.rand) }; // true always

Function-matchItem

Test item by passing it to a function which should return a Boolean.a = [10, 20, 30, { |item| item.isPrime }]; a.any { |x| x.matchItem(3) }; // true a.any { |x| x.matchItem(4) }; // false a.any { |x| x.matchItem(10) }; // true
