Methods

Modifier and Type	Method and Description
long	get(int relativeOffset) Returns the value at a position relative to the current position.
boolean	hasNext()
int	index()
void	move(int offset) Changes the current position of the iterator.
protected void	nextImpl() Called before any call to AbstractLongIteratorWithFlag.valueImpl(), should be used to either initialize the state or advance the iterator.
protected long	valueImpl() Called after any call to AbstractLongIteratorWithFlag.nextImpl(), should return value of iterator.

Constructor Detail

LongListIndexedIterator

public LongListIndexedIterator(LongList source,
                       IntListIterator indexIterator)

Method Detail

hasNext

public boolean hasNext()

Specified by:

hasNext in interface LongIterator

Specified by:

hasNext in interface java.util.Iterator<LongIterator>

Returns:

true if next call to Iterator.next() or LongIterator.nextValue() won't throw NoSuchElementException

move

public void move(int offset)
          throws java.util.ConcurrentModificationException,
                 java.util.NoSuchElementException

Description copied from interface: LongListIterator

Changes the current position of the iterator.

Specified by:

move in interface LongListIterator

Parameters:

offset - the difference between new and old iterator indices. Zero won't change iterator state. Positive value will move it to greater indices, negative - to smaller indices.

Throws:

java.util.ConcurrentModificationException

java.util.NoSuchElementException

get

public long get(int relativeOffset)
         throws java.util.NoSuchElementException

Description copied from interface: LongListIterator

Returns the value at a position relative to the current position.

get(0) will return the same value as value(), get(-1) will return value at index()-1, etc.

Specified by:

get in interface LongListIterator

Throws:

java.util.NoSuchElementException

index

public int index()
          throws java.util.NoSuchElementException

Specified by:

index in interface LongListIterator

Returns:

The current position of the iterator.
move(p) would change index by p, Iterator.next() and LongIterator.nextValue() would change it by 1.

Throws:

java.util.NoSuchElementException - if iterator has never been advanced (Iterator.next() or LongIterator.nextValue() weren't ever called)

nextImpl

protected void nextImpl()
                 throws java.util.ConcurrentModificationException,
                        java.util.NoSuchElementException

Description copied from class: AbstractLongIteratorWithFlag

Called before any call to AbstractLongIteratorWithFlag.valueImpl(), should be used to either initialize the state or advance the iterator.

Specified by:

nextImpl in class AbstractLongIteratorWithFlag

Throws:

java.util.ConcurrentModificationException

java.util.NoSuchElementException

valueImpl

protected long valueImpl()
                  throws java.util.NoSuchElementException

Description copied from class: AbstractLongIteratorWithFlag

Called after any call to AbstractLongIteratorWithFlag.nextImpl(), should return value of iterator. Can safely assume that the iterator is initialized.

Specified by:

valueImpl in class AbstractLongIteratorWithFlag

Throws:

java.util.NoSuchElementException
