Returns the number of elements in the iterator. If this information is unavailable, returns -1.

Specified by:

getSize in interface javax.jcr.RangeIterator

Returns:

a long

getPosition

long getPosition()

Returns the current position within the iterator. The number returned is the 0-based index of the next element in the iterator, i.e. the one that will be returned on the subsequent next call. <p/> Note that this method does not check if there is a next element, i.e. an empty iterator will always return 0.
