      Creates an Elias–Fano representation of the values returned by an iterator, given that the overall number of elements and an upper bound are provided, too.

      This constructor is particularly useful if the elements of the iterator are provided by some sequential source.

      Parameters:

      Creates an Elias–Fano representation of the values returned by an iterator, given that the overall number of elements and an upper bound are provided, too.

      This constructor is particularly useful if the elements of the iterator are provided by some sequential source.

      Parameters:
      n - the number of elements returned by iterator.
      upperBound - a strict upper bound to the values returned by iterator (note that it used to be non-strict).
      iterator - an iterator returning nondecreasing natural numbers.

    • EliasFanoMonotoneBigLongBigList

      Creates an Elias–Fano representation of the values returned by an iterator, given that the overall number of elements and an upper bound are provided, too.

      This constructor is particularly useful if the elements of the iterator are provided by some sequential source.

      Parameters:
      n - the number of elements returned by iterator.
      upperBound - a strict upper bound to the values returned by iterator (note that it used to be non-strict).
      iterator - an iterator returning nondecreasing natural numbers.

    • EliasFanoMonotoneBigLongBigList

      public EliasFanoMonotoneBigLongBigList(long n, long upperBound, it.unimi.dsi.fastutil.longs.LongIterator iterator)
      Creates an Elias–Fano representation of the values returned by an iterator, given that the overall number of elements and an upper bound are provided, too.

      This constructor is particularly useful if the elements of the iterator are provided by some sequential source.

      Parameters:
      n - the number of elements returned by iterator.
      upperBound - a strict upper bound to the values returned by iterator (note that it used to be non-strict).
      iterator - an iterator returning nondecreasing natural numbers.

    • EliasFanoMonotoneBigLongBigList

      protected EliasFanoMonotoneBigLongBigList(long[] a, it.unimi.dsi.fastutil.longs.LongIterator iterator)
      Creates an Elias–Fano representation of the values returned by an iterator, given that the overall number of elements and an upper bound are provided, too.

      This constructor is used only internally, to work around the usual problems caused by the obligation to call this() before anything else.

      Parameters:
      a - an array containing the number of elements returned by iterator and a strict upper bound to the values returned by iterator (note that it used to be non-strict).
      iterator - an iterator returning nondecreasing natural numbers.
