public interface LongBidirectionalIterator
extends it.unimi.dsi.fastutil.longs.LongIterator, it.unimi.dsi.fastutil.objects.ObjectBidirectionalIterator<java.lang.Long>

A type-specific bidirectional iterator; provides an additional method to avoid (un)boxing, and the possibility to skip elements backwards.

Method Detail

previousLong

long previousLong()

Returns the previous element as a primitive type.

Returns:

the previous element in the iteration.

See Also:

ListIterator.previous()

previous

@Deprecated
default java.lang.Long previous()

Deprecated. Please use the corresponding type-specific method instead.

Specified by:

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

back

default int back(int n)

Moves back for the given number of elements.

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

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.

skip

default int skip(int n)
