Just like chatter and chattee, employer and employee, there is an iterator (usually as part of an enumerator/ee) and an iteratee.
Thanks for the attempt to explain. But I, at least, remain mystified, and I agree with Douglas that the terminology is confusing. Usually, the relationship between word-pairs such as the ones above is pretty obvious, typically implying some kind of subordinate relationship. For example: * employer: the one employing employee: the one employed * tutor: the one teaching, instructing, providing care tutee: the one receiving instruction, care * caller: that which is calling callee: that which is being called And so on. The above would suggest that "iterator" would be something that iterates over something, and that "iteratee" would be (an element of) that being iterated over. However, no such simple relationship seems to emerge from the provided explanation. I also had a look at John Millikin's page on Understanding Iteratees, which is very good: https://john-millikin.com/articles/understanding-iteratees/ But, the intuition that comes across there is: * iteratee: a stream (of sorts) consumer * enumerator: a stream (of sorts) producer * enumeratee: a stream (of sorts) transformer And "iterator" isn't mentioned at all. I might be missing something, but the terminology is hardly crystal clear. Which is a pity! Best, /Henrik -- Henrik Nilsson School of Computer Science The University of Nottingham nhn@cs.nott.ac.uk
