isCompatibleTo method
Checks whether this is compatible to the other
nested result, which is
the case iff they have the same and read from the same table.
Implementation
@override
bool isCompatibleTo(NestedResult other) {
if (other is! NestedResultTable) return false;
return other.name == name &&
other.table == table &&
other.isNullable == isNullable;
}
