Method Details
-
hasNext
boolean hasNext()Check if there is a next element. Does not move the iterator.- Returns:
true
iff there is a next element.
-
next
Return the next feature structure and increment the iterator.- Returns:
- The next feature structure.
- Throws:
NoSuchElementException
- If no next element exists, i.e., when the iterator points at the last position in the index.
-
hasPrevious
boolean hasPrevious()Check if there is a previous element. Does not move the iterator.- Returns:
true
iff there is a previous element.
-
previous
int previous()Return the previous feature structure and decrement the iterator.- Returns:
- The previous feature structure.
- Throws:
NoSuchElementException
- If no previous element exists, i.e., when the iterator points at the first position in the index.
-
moveToStart
void moveToStart()Move the iterator to the start of the underlying index. -
moveToEnd
void moveToEnd()Move the iterator to the end of the underlying index.
