Method Detail

findNext

protected abstract boolean findNext()
                             throws java.util.ConcurrentModificationException

In this method myNext should be assigned the next value.

Returns:

true if the next value exists and was assigned to myNext, otherwise false

Throws:

java.util.ConcurrentModificationException

hasNext

public final boolean hasNext()
                      throws java.util.ConcurrentModificationException

Returns:

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

Throws:

java.util.ConcurrentModificationException

next

public IntIterator next()
                 throws java.util.ConcurrentModificationException,
                        java.util.NoSuchElementException

Throws:

java.util.ConcurrentModificationException

java.util.NoSuchElementException

value

public int value()
          throws java.util.NoSuchElementException

Throws:

java.util.NoSuchElementException - if iterator has never been advanced (Iterator.next() or IntIterator.nextValue() have never been called)

hasValue

public boolean hasValue()

Returns:

false if this iterator has never been advanced. In other words, returns false if the subsequent call to IntIterator.value() will throw NoSuchElementException, otherwise true.
