public class ShortArraySet extends AbstractShortSet implements Serializable, Cloneable
A simple, brute-force implementation of a set based on a backing array.

The main purpose of this implementation is that of wrapping cleanly the brute-force approach to the storage of a very small number of items: just put them into an array and scan linearly to find an item.

      Parameters:
      a - the backing array.

      public ShortArraySet()
      Creates a new empty array set.

    • ShortArraySet

      public ShortArraySet(int capacity)
      Creates a new empty array set of given initial capacity.
      Parameters:
      capacity - the initial capacity.

    • ShortArraySet

      public ShortArraySet(ShortCollection c)
      Creates a new array set copying the contents of a given collection.
      Parameters:
      c - a collection.

    • ShortArraySet

      public ShortArraySet(Collection<? extends Short> c)
      Creates a new array set copying the contents of a given set.
      Parameters:

    • ShortArraySet

      public ShortArraySet(Set<? extends Short> c)
      Creates a new array set copying the contents of a given set.
      Parameters:
      c - a collection.

    • ShortArraySet

      public ShortArraySet(short[] a, int size)
      Creates a new array set using the given backing array and the given number of elements of the array.

      It is the responsibility of the caller to ensure that the first size elements of a are distinct.

      Parameters:
      a - the backing array.
      size - the number of valid elements in a.
