hasPrevious
public boolean hasPrevious()
Description copied from interface:BidirectionalIterator
Returns whether there is a previous element.- Specified by:
hasPrevious
in interfaceBidirectionalIterator<Byte>
- Specified by:
hasPrevious
in interfaceListIterator<Byte>
- Returns:
- whether there is a previous element.

nextByte
public byte nextByte()
Description copied from interface:ByteIterator
Returns the next element as a primitive type.- Specified by:
nextByte
in interfaceByteIterator
- Returns:
- the next element in the iteration.

skip
public int skip(int n)
Description copied from interface:ByteBidirectionalIterator
Skips the given number of elements.The effect of this call is exactly the same as that of calling
ByteIterator.next()
forn
times (possibly stopping ifIterator.hasNext()
becomes false).- Specified by:

n
- the number of elements to skip.- Returns:
- the number of elements actually skipped.
- See Also:
Iterator.next()

times (possibly stopping ifBidirectionalIterator.hasPrevious()
becomes false).- Specified by:
back
in interfaceByteBidirectionalIterator
- Specified by:
back
in interfaceObjectBidirectionalIterator<Byte>
