All Implemented Interfaces:

BidirectionalIterator<Byte>, ByteBidirectionalIterator, ByteIterator, ByteListIterator, ObjectBidirectionalIterator<Byte>, ObjectIterator<Byte>, Serializable, Cloneable, Iterator<Byte>, ListIterator<Byte>

Enclosing class:

ByteIterators

public static class ByteIterators.EmptyIterator
extends Object
implements ByteListIterator, Serializable, Cloneable

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

Method Detail

hasNext

public boolean hasNext()

Specified by:

hasNext in interface Iterator<Byte>

Specified by:

hasNext in interface ListIterator<Byte>

hasPrevious

public boolean hasPrevious()

Description copied from interface: BidirectionalIterator

Returns whether there is a previous element.

Specified by:

hasPrevious in interface BidirectionalIterator<Byte>

Specified by:

hasPrevious in interface ListIterator<Byte>

Returns:

whether there is a previous element.

See Also:

ListIterator.hasPrevious()

nextByte

public byte nextByte()

Description copied from interface: ByteIterator

Returns the next element as a primitive type.

Specified by:

nextByte in interface ByteIterator

Returns:

the next element in the iteration.

See Also:

Iterator.next()

previousByte

public byte previousByte()

Description copied from interface: ByteBidirectionalIterator

Returns the previous element as a primitive type.

Specified by:

previousByte in interface ByteBidirectionalIterator

Returns:

the previous element in the iteration.

See Also:

ListIterator.previous()

nextIndex

public int nextIndex()

Specified by:

nextIndex in interface ListIterator<Byte>

previousIndex

public int previousIndex()

Specified by:

previousIndex in interface ListIterator<Byte>

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() for n times (possibly stopping if Iterator.hasNext() becomes false).

Specified by:

skip in interface ByteBidirectionalIterator

Specified by:

skip in interface ByteIterator

Specified by:

skip in interface ObjectBidirectionalIterator<Byte>

Specified by:

skip in interface ObjectIterator<Byte>

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: ByteBidirectionalIterator

Moves back for the given number of elements.

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

Specified by:

back in interface ByteBidirectionalIterator

Specified by:

back in interface ObjectBidirectionalIterator<Byte>

Parameters:

n - the number of elements to skip back.

Returns:

the number of elements actually skipped.

See Also:

ByteBidirectionalIterator.previous()

clone

public Object clone()

Overrides:

clone in class Object
