interface of a generic message iterator.
provides sequential access to the attributes of a message.

pure virtual |
moves this iterator to the next attribute in the sequence.
true
if the element pointed to by this iterator before this call to next() is not the last attribute in its message. In this case, after this call to next(), this iterator will point to the next attribute. false
if the element pointed to by this iterator before this call to next() is either the the last attribute in its message, or an invalid attribute. In this case, after this call to next(), this iterator will point to an invalid attribute.
