    • find

      public <C, K> int find(C collection, int from, int to, io.smallrye.common.function.ObjIntFunction<C,K> keyExtractor, Predicate<K> keyTester)
      Get the lowest index within the given range that satisfies the given test.
      Type Parameters:
      C - the collection type
      K - the key type
      Parameters:
      collection - the collection object (must not be null)
      from - the low end of the range (inclusive)
      to - the high end of the range (exclusive)
      keyExtractor - the key extraction function (must not be null)
      keyTester - the test for the key (must not be null)
      Returns:
      the lowest index within the range which satisfies the test, or to if no values satisfy the test within the range
