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 Long previous()
Deprecated.Please use the corresponding type-specific method instead.Returns the previous element from the collection.- Specified by:
previous
in interfaceBidirectionalIterator<Long>
- Returns:
- the previous element from the collection.
- See Also:
ListIterator.previous()
-
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()
forn
times (possibly stopping ifBidirectionalIterator.hasPrevious()
becomes false).- Specified by:
back
in interfaceObjectBidirectionalIterator<Long>
- Parameters:
n
- the number of elements to skip back.- Returns:
- the number of elements actually skipped.
- See Also:
previous()
-
skip
default int skip(int n)
Skips the given number of elements.The effect of this call is exactly the same as that of calling
LongIterator.next()
forn
times (possibly stopping ifIterator.hasNext()
becomes false).- Specified by:
skip
in interfaceLongIterator
- Specified by:
skip
in interfaceObjectBidirectionalIterator<Long>
- Specified by:
skip
in interfaceObjectIterator<Long>
- Parameters:
n
- the number of elements to skip.- Returns:
- the number of elements actually skipped.
