hasNext
public boolean hasNext()
-
hasPrevious
public boolean hasPrevious()
Description copied from interface:BidirectionalIterator
Returns whether there is a previous element.- Specified by:
hasPrevious
in interfaceBidirectionalIterator<Boolean>
- Specified by:
hasPrevious
in interfaceListIterator<Boolean>
- Returns:
- whether there is a previous element.
- See Also:
ListIterator.hasPrevious()
-
nextBoolean
public boolean nextBoolean()
Description copied from interface:BooleanIterator
Returns the next element as a primitive type.- Specified by:
nextBoolean
in interfaceBooleanIterator
- Returns:
- the next element in the iteration.
- See Also:
Iterator.next()

previousBoolean
public boolean previousBoolean()
Description copied from interface:BooleanBidirectionalIterator
Returns the previous element as a primitive type.- Specified by:
previousBoolean
in interfaceBooleanBidirectionalIterator

skip
public int skip(int n)
Description copied from interface:BooleanBidirectionalIterator
Skips the given number of elements.The effect of this call is exactly the same as that of calling
BooleanIterator.next()
forn
times (possibly stopping ifIterator.hasNext()
becomes false).- Specified by:
skip
in interfaceBooleanBidirectionalIterator
- Specified by:
skip
in interfaceBooleanIterator
- Specified by:
skip
in interfaceObjectBidirectionalIterator<Boolean>
- Specified by:
skip
in interfaceObjectIterator<Boolean>
- Parameters:
n
- the number of elements to skip.- Returns:
- the number of elements actually skipped.
- See Also:
Iterator.next()
-
back
public int back(int n)
Description copied from interface:BooleanBidirectionalIterator
Moves back for the given number of elements.The effect of this call is exactly the same as that of calling
BooleanBidirectionalIterator.previous()
forn
times (possibly stopping ifBidirectionalIterator.hasPrevious()
becomes false).- Specified by:
back
in interfaceBooleanBidirectionalIterator
- Specified by:
back
in interfaceObjectBidirectionalIterator<Boolean>
- Parameters:
n
- the number of elements to skip back.- Returns:
- the number of elements actually skipped.
