Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
```
@FunctionalInterface
public interface LastPositionFinder
```
A LastPositionFinder is an interface implemented by any SequenceIterator that is able to return the position of the last item in the sequence.

- Method Summary
  
  All Methods Instance Methods Abstract Methods
  Modifier and Type Method Description
  
  int getLength()
  Get the last position (that is, the number of items in the sequence).

- Method Detail
  - getLength
```
int getLength()
       throws XPathException
```
    Get the last position (that is, the number of items in the sequence). This method is non-destructive: it does not change the state of the iterator. The result is undefined if the next() method of the iterator has already returned null. This method must not be called unless the result of getProperties() on the iterator includes the bit setting SequenceIterator.Property.LAST_POSITION_FINDER
    
    Returns:
    
    the number of items in the sequence
    
    Throws:
    
    XPathException - if an error occurs evaluating the sequence in order to determine the number of items
