Method Detail

doGetNext

protected abstract Object doGetNext()

Returns:

'next', whatever that means for a given kind of BinaryTreeIterator

hasNext

public final boolean hasNext()

Specified by:

hasNext in interface Iterator

Returns:

true if the iterator has more elements.

next

public final Object next()
                  throws NoSuchElementException,
                         ConcurrentModificationException

Specified by:

next in interface Iterator

Returns:

the next element in the iteration.

Throws:

NoSuchElementException - if iteration has no more elements.

ConcurrentModificationException - if the BinaryTree is modified behind the iterator's back

remove

public final void remove()
                  throws IllegalStateException,
                         ConcurrentModificationException

Removes from the underlying collection the last element returned by the iterator. This method can be called only once per call to next. The behavior of an iterator is unspecified if the underlying collection is modified while the iteration is in progress in any way other than by calling this method.

Specified by:

remove in interface Iterator

Throws:

IllegalStateException - if the next method has not yet been called, or the remove method has already been called after the last call to the next method.

ConcurrentModificationException - if the BinaryTree is modified behind the iterator's back
