Interface OpIterator

src/java/simpledb/OpIterator.java:13–56 · view source on GitHub ↗

OpIterator is the iterator interface that all SimpleDB operators should implement. If the iterator is not open, none of the methods should work, and should throw an IllegalStateException. In addition to any resource allocation/deallocation, an open method should call any child iterator open methods
