Enclosing class:

ShortIterators

public static class ShortIterators.EmptyIterator
extends java.lang.Object
implements ShortListIterator, java.io.Serializable, java.lang.Cloneable

Method Detail

hasNext

public boolean hasNext()

Specified by:

hasNext in interface java.util.Iterator<java.lang.Short>

Specified by:

hasNext in interface java.util.ListIterator<java.lang.Short>

hasPrevious

public boolean hasPrevious()

Description copied from interface: BidirectionalIterator

Returns whether there is a previous element.

Specified by:

hasPrevious in interface BidirectionalIterator<java.lang.Short>

Specified by:

hasPrevious in interface java.util.ListIterator<java.lang.Short>

Returns:

whether there is a previous element.

See Also:

ListIterator.hasPrevious()

nextShort

public short nextShort()

Description copied from interface: ShortIterator

Returns the next element as a primitive type.

Specified by:

nextShort in interface ShortIterator

Returns:

the next element in the iteration.

See Also:

Iterator.next()

previousShort

public short previousShort()

Description copied from interface: ShortBidirectionalIterator

Returns the previous element as a primitive type.

Specified by:

previousShort in interface ShortBidirectionalIterator

Returns:

the previous element in the iteration.

See Also:

ListIterator.previous()

nextIndex

public int nextIndex()

Specified by:

nextIndex in interface java.util.ListIterator<java.lang.Short>

previousIndex

public int previousIndex()

Specified by:

previousIndex in interface java.util.ListIterator<java.lang.Short>

skip

public int skip(int n)

Description copied from interface: ShortBidirectionalIterator

Skips the given number of elements.

The effect of this call is exactly the same as that of calling ShortIterator.next() for n times (possibly stopping if Iterator.hasNext() becomes false).

Specified by:

skip in interface ObjectBidirectionalIterator<java.lang.Short>

Specified by:

skip in interface ObjectIterator<java.lang.Short>

Specified by:

skip in interface ShortBidirectionalIterator

Specified by:

skip in interface ShortIterator

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: ShortBidirectionalIterator

Moves back for the given number of elements.

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

Specified by:

back in interface ObjectBidirectionalIterator<java.lang.Short>

Specified by:

back in interface ShortBidirectionalIterator

Parameters:

n - the number of elements to skip back.

Returns:

the number of elements actually skipped.

See Also:

ShortBidirectionalIterator.previous()

clone

public java.lang.Object clone()

Overrides:

clone in class java.lang.Object
