Detailed Description

iterator for a BSONObj

Note each BSONObj ends with an EOO element: so you will get more() on an empty object, although next().eoo() will be true.

The BSONObj must stay in scope for the duration of the iterator's execution.

todo: we may want to make a more stl-like iterator interface for this with things like begin() and end()

bool mongo::BSONObjIterator::moreWithEOO ( )
inline
Returns
true if more elements exist to be enumerated INCLUDING the EOO element which is always at the end.
BSONElement mongo::BSONObjIterator::next ( bool  checkEnd)
inline
Returns
the next element in the object. For the final element, element.eoo() will be true.
