A question came up for me, as a Jena newbie, in the course of JENA-966: "LazyIterator".
The type ExtendedIterator in jena-core is used widely through jena-core. It features several convenient methods for use with iteration, like mapping through functions, filtering, and concatenation. The type Iter in jena-base is used widely through jena-base and jena-arq. It features many convenient methods for use with iteration, like everything ExtendedIterator does plus much more, (e.g. folding, selecting, reducing…). What is the difference in use for these two types? Why are they distinct? Is there some means by which it can be made clear when to use each and why? I would be happy to write a simple class Javadoc for Iter (which currently has none at all) to let folks know when to use it, if someone will explain that to me. --- A.
