    void
    XmlResults::reset()

# Description

The XmlResults::reset method reset the results iterator, for eager evaluation. If the query was processed with eager evaluation then reset will reset the iterator so a subsequent call to XmlResults::next method will return the first value in the result set. If the query was processed with lazy evaluation then XmlResults::reset will have no effect.

The XmlResults::reset method throws an exception that encapsulates a non-zero error value on failure.

# Errors

If the requested item could not be returned due to insufficient memory, the XmlResults::reset method will fail and throw a DbMemoryException exception.

The XmlResults::reset method may fail and throw an exception for errors specified for other Berkeley DB and C library or system methods. If a catastrophic error has occurred, the XmlResults::reset method may fail and throw a DbRunRecoveryException, in which case all subsequent Berkeley DB calls will fail in the same way.
