SUMMARY: NESTED | FIELD | CONSTR | METHOD | DETAIL: FIELD | CONSTR | METHOD |
An iterator over a bag of sequences.
java.util.Iterator was not appropriate here, as we need specific exceptions to be thrown, and as much type-safety as possible. However, we have made it as compliant with Iterator as we could so that there is a minimal learning curve.

Returns the next sequence in the iterator. |
