Class MergedLongIterator

java.lang.Object
it.unimi.dsi.big.webgraph.MergedLongIterator
All Implemented Interfaces:
LazyLongIterator

public class MergedLongIterator
extends Object
implements LazyLongIterator
An iterator returning the union of the integers returned by two IntIterators. The two iterators must return integers in an increasing fashion; the resulting MergedLongIterator will do the same. Duplicates will be eliminated.
  • Constructor Details

    • MergedLongIterator

      public MergedLongIterator​(LazyLongIterator it0, LazyLongIterator it1)
      Creates a new merged iterator by merging two given iterators.
      Parameters:
      it0 - the first (monotonically nondecreasing) component iterator.
      it1 - the second (monotonically nondecreasing) component iterator.
    • MergedLongIterator

      public MergedLongIterator​(LazyLongIterator it0, LazyLongIterator it1, long n)
      Creates a new merged iterator by merging two given iterators; the resulting iterator will not emit more than n integers.
      Parameters:
      it0 - the first (monotonically nondecreasing) component iterator.
      it1 - the second (monotonically nondecreasing) component iterator.
      n - the maximum number of integers this merged iterator will return.
  • Method Details

    • nextLong

      public long nextLong()
      Description copied from interface: LazyLongIterator
      The next long returned by this iterator, or the special marker if this iterator is exhausted.
      Specified by:
      nextLong in interface LazyLongIterator
      Returns:
      next long returned by this iterator, or the special marker if this iterator is exhausted.
    • skip

      public long skip​(long s)
      Description copied from interface: LazyLongIterator
      Skips a given number of elements.
      Specified by:
      skip in interface LazyLongIterator
      Parameters:
      s - the number of elements to skip.
      Returns:
      the number of elements actually skipped (which might be less than n if this iterator is exhausted).
