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
IntIterator
s.
The two iterators must return integers in an increasing fashion; the resulting
MergedLongIterator
will do the same. Duplicates will be eliminated.-

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 interfaceLazyLongIterator
- 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 interfaceLazyLongIterator
- 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).
