  • Method Details

    • getShort

      public short getShort​(long i)
      Description copied from interface: ShortBigList
      Returns the element at the specified position.
      Specified by:
      getShort in interface ShortBigList
      See Also:
      BigList.get(long)

    • rem

      public boolean rem​(short k)
      Description copied from class: AbstractShortCollection
      Removes a single instance of the specified element from this collection, if it is present (optional operation).

      Note that this method should be called remove(), but the clash with the similarly named index-based method in the List interface forces us to use a distinguished name. For simplicity, the set interfaces reinstates remove().

      This implementation iterates over the elements in the collection, looking for the specified element and tries to remove it.
