    • clear

      public void clear()

    • dropTailTo

      public int dropTailTo(long indexInclusive)
      Remove all elements from tailSequence back to indexInclusive.
      At the end of this operation tailSequence is equals to indexInclusive. 
       eg:
 elements = [A, B, C]
 tail = 3
 head = 0

 dropTailTo(1)

 elements = [A]
 tail = 1
 head = 0

    • dropHeadUntil

      public int dropHeadUntil(long indexExclusive)
      Remove all elements from headSequence to indexExclusive.
      At the end of this operation headSequence is equals to indexExclusive. 
       eg:
 elements = [A, B, C]
 tail = 3
 head = 0

 dropHeadUntil(1)

 elements = [B, C]
 tail = 3
 head = 1
