NAME

       MongoDB::BulkWriteResult - MongoDB bulk write result document

VERSION

       version v1.8.1

SYNOPSIS

           # returned directly
           my $result = $bulk->execute;

           # from a WriteError or WriteConcernError
           my $result = $error->result;

           if ( $result->acknowledged ) {
               ...
           }

DESCRIPTION

       This class encapsulates the results from a bulk write operation. It may be returned
       directly from "execute" or it may be in the "result" attribute of a
       "MongoDB::DatabaseError" subclass like "MongoDB::WriteError" or
       "MongoDB::WriteConcernError".

ATTRIBUTES

   inserted_count
       Number of documents inserted

   upserted_count
       Number of documents upserted

   matched_count
       Number of documents matched for an update or replace operation.

   deleted_count
       Number of documents removed

   modified_count
       Number of documents actually modified by an update operation. This is not necessarily the
       same as "matched_count" if the document was not actually modified as a result of the
       update.

       This field is not available from legacy servers before version 2.6.  If results are seen
       from a legacy server (or from a mongos proxying for a legacy server) this attribute will
       be "undef".

       You can call "has_modified_count" to find out if this attribute is defined or not.

   upserted
       An array reference containing information about upserted documents (if any).  Each
       document will have the following fields:

       •   index — 0-based index indicating which operation failed

       •   _id — the object ID of the upserted document

   upserted_ids
       A hash reference built lazily from "upserted" mapping indexes to object IDs.

   inserted
       An array reference containing information about inserted documents (if any).  Documents
       are just as in "upserted".

   inserted_ids
       A hash reference built lazily from "inserted" mapping indexes to object IDs.

   write_errors
       An array reference containing write errors (if any).  Each error document will have the
       following fields:

       •   index — 0-based index indicating which operation failed

       •   code — numeric error code

       •   errmsg — textual error string

       •   op — a representation of the actual operation sent to the server

   write_concern_errors
       An array reference containing write concern errors (if any).  Each error document will
       have the following fields:

       •   index — 0-based index indicating which operation failed

       •   code — numeric error code

   op_count
       The number of operations sent to the database.

   batch_count
       The number of database commands issued to the server.  This will be less than the
       "op_count" if multiple operations were grouped together.

METHODS

   assert
       Throws an error if write errors or write concern errors occurred.

   assert_no_write_error
       Throws a MongoDB::WriteError if "count_write_errors" is non-zero; otherwise returns 1.

   assert_no_write_concern_error
       Throws a MongoDB::WriteConcernError if "count_write_concern_errors" is non-zero; otherwise
       returns 1.

   count_write_errors
       Returns the number of write errors

   count_write_concern_errors
       Returns the number of write errors

   last_code
       Returns the last "code" field from either the list of "write_errors" or
       "write_concern_errors" or 0 if there are no errors.

   last_errmsg
       Returns the last "errmsg" field from either the list of "write_errors" or
       "write_concern_errors" or the empty string if there are no errors.

   last_wtimeout
       True if a write concern timed out or false otherwise.
