Returns the total number of of items available through this iterator. For example, for some node N, N.getNodes().getSize() returns the number of child nodes of N visible through the current Session. In some implementations precise information about the number of elements may not be available. In such cases this method must return -1. API clients will then be able to use RangeIterator.getNumberRemaining to get an estimate on the number of elements.
