ProxyLongListIterator()
Method Detail

hasPrevious

public boolean hasPrevious()
Description copied from interface: LongListIterator
Returns true iff I have more elements when traversed in the reverse direction. (In other words, returns true iff a call to LongListIterator.previous() will return an element rather than throwing an exception.

Specified by:
hasPrevious in interface LongListIterator
Returns:
true iff I have more elements when traversed in the reverse direction

nextIndex

public int nextIndex()
Description copied from interface: LongListIterator
Returns the index of the element that would be returned by a subsequent call to LongListIterator.next(), or the number of elements in my iteration if I have no next element.

Specified by:
nextIndex in interface LongListIterator
Returns:
the index of the next element in me

previous

public long previous()
Description copied from interface: LongListIterator
Returns the next element in me when traversed in the reverse direction.

Specified by:
previous in interface LongListIterator
Returns:
the previous element in me

previousIndex

public int previousIndex()
Description copied from interface: LongListIterator
Returns the index of the element that would be returned by a subsequent call to LongListIterator.previous(), or -1 if I have no previous element.

Specified by:
previousIndex in interface LongListIterator
Returns:
the index of the previous element in me

getIterator

protected final LongIterator getIterator()
Specified by:
getIterator in class ProxyLongIterator

getListIterator

protected abstract LongListIterator getListIterator()

hasNext

public boolean hasNext()
Description copied from interface: LongIterator
Returns true iff I have more elements. (In other words, returns true iff a subsequent call to next will return an element rather than throwing an exception.)

Specified by:
hasNext in interface LongIterator
Returns:
true iff I have more elements

next

public long next()
Description copied from interface: LongIterator
Returns the next element in me.

Specified by:
next in interface LongIterator
Returns:
the next element in me
