When updating via Mongo Shell (MongoDB 2.6.0) we get 3 'n' numbers :
bippo:PRIMARY> db.salesOrder.update({formalId: '100000001'}, {'$unset': {formalIdTrie: ''}});
WriteResult({ "nMatched" : 1, "nUpserted" : 0, "nModified" : 0 })
However only `WriteResult.getN()` is provided by the Java API. From the mongo-java-driver 2.12.1 implementation :
/**
* Gets the "n" field, which contains the number of documents
* affected in the write operation.
* @return the number of documents modified by the write operation
* @throws MongoException
*/
public int getN(){
return getLastError().getInt( "n" );
}
is it correct? Since there seems to be no n field in the WriteResult object when observed via Mongo shell.
