NAME
MongoDB::BulkWriteResult - MongoDB bulk write result document

VERSION
version v2.2.2

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:

o index -- 0-based index indicating which operation failed

o _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:

o index -- 0-based index indicating which operation failed

o code -- numeric error code

o errmsg -- textual error string

o 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:

o index -- 0-based index indicating which operation failed

o 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.
