Method Details
-
hasNext
Returns true if the iteration has more elements. (In other words, returns true if next would return an element rather than throwing an exception.)- Parameters:
txn
- Txn used for this operation- Returns:
- true if the iterator has more elements.
-
next
Returns the next element in the iteration.- Parameters:
txn
- Txn used for this operation- Returns:
- the next element in the iteration.
- Throws:
NoSuchElementException
- iteration has no more elements.
-
remove
Removes from the underlying collection the last element returned by the iterator (optional operation). 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.- Parameters:
txn
- Txn used for this operation- Throws:
UnsupportedOperationException
- if the remove operation is not supported by this Iterator.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.
