    • Constructor Detail

      • OrderedSet

        public OrderedSet()
        Constructs a new, empty set; the backing HashMap instance has default initial capacity (16) and load factor (0.75).

      • OrderedSet

        public OrderedSet​(Collection c)
        Constructs a new set containing the elements in the specified collection. The Set is created with default load factor (0.75) and an initial capacity sufficient to contain the elements in the specified collection.

        c - the collection whose elements are to be placed into this set.
        Throws:
        NullPointerException - if the specified collection is null.

      • OrderedSet

                  float loadFactor)
        Constructs a new, empty set; the backing Set instance has the specified initial capacity and the specified load factor.
        Parameters:
