Compares two vectors of attributes.
They are considered equal if all their members contain the same value and NULL flag. This was introduced because the default Qt implementation of QVariant comparison does not handle NULL values for certain types (like int).
v | The attributes to compare |

QgsAttributeMap QgsAttributes::toMap | ( | ) | const |
Returns a QgsAttributeMap of the attribute values.
Null values are excluded from the map.
