  • Method Details

    • getByte

      public byte getByte(int i)
      Description copied from interface: ByteList
      Returns the element at the specified position in this list.
      Specified by:
      getByte in interface ByteList
      See Also:

    • rem

      public boolean rem(byte k)
      Description copied from class: AbstractByteCollection
      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().
