Enclosing class:

LongIterators

public static class LongIterators.EmptyIterator
extends java.lang.Object
implements LongListIterator, java.io.Serializable, java.lang.Cloneable

A class returning no elements and a type-specific iterator interface.

This class may be useful to implement your own in case you subclass a type-specific iterator.

Method Detail

hasNext

public boolean hasNext()

Specified by:

hasNext in interface java.util.Iterator<java.lang.Long>

Specified by:

hasNext in interface java.util.ListIterator<java.lang.Long>

hasPrevious

public boolean hasPrevious()

Specified by:

hasPrevious in interface it.unimi.dsi.fastutil.BidirectionalIterator<java.lang.Long>

Specified by:

hasPrevious in interface java.util.ListIterator<java.lang.Long>

nextLong

public long nextLong()

Specified by:

nextLong in interface it.unimi.dsi.fastutil.longs.LongIterator

Specified by:

nextLong in interface java.util.PrimitiveIterator.OfLong

previousLong

public long previousLong()

Description copied from interface: LongBidirectionalIterator

Returns the previous element as a primitive type.

Specified by:

previousLong in interface LongBidirectionalIterator

Returns:

the previous element in the iteration.

See Also:

ListIterator.previous()

nextIndex

public int nextIndex()

Specified by:

nextIndex in interface java.util.ListIterator<java.lang.Long>

previousIndex

public int previousIndex()

Specified by:

previousIndex in interface java.util.ListIterator<java.lang.Long>

skip

public int skip(int n)

Description copied from interface: LongBidirectionalIterator

Specified by:

skip in interface LongBidirectionalIterator

Specified by:

skip in interface it.unimi.dsi.fastutil.longs.LongIterator

Specified by:

skip in interface it.unimi.dsi.fastutil.objects.ObjectBidirectionalIterator<java.lang.Long>

Specified by:

skip in interface it.unimi.dsi.fastutil.objects.ObjectIterator<java.lang.Long>

back

public int back(int n)

Description copied from interface: LongBidirectionalIterator

Moves back for the given number of elements.

The effect of this call is exactly the same as that of calling LongBidirectionalIterator.previous() for n times (possibly stopping if BidirectionalIterator.hasPrevious() becomes false).

Specified by:

back in interface LongBidirectionalIterator

Specified by:

back in interface it.unimi.dsi.fastutil.objects.ObjectBidirectionalIterator<java.lang.Long>

Parameters:

n - the number of elements to skip back.

Returns:

the number of elements actually skipped.
