=head1 NAME
MongoDB::BulkWriteView - Bulk write operations against a query document
=head1 VERSION
version v1.2.2
=head1 SYNOPSIS
my $bulk = $collection->initialize_ordered_bulk_op;
# Update one document matching the selector
bulk->find( { a => 1 } )->update_one( { '$inc' => { x => 1 } } );
# Update all documents matching the selector
bulk->find( { a => 2 } )->update_many( { '$inc' => { x => 2 } } );
# Update all documents
bulk->find( {} )->update_many( { '$inc' => { x => 2 } } );
# Replace entire document (update with whole doc replace)
bulk->find( { a => 3 } )->replace_one( { x => 3 } );
# Update one document matching the selector or upsert
bulk->find( { a => 1 } )->upsert()->update_one( { '$inc' => { x => 1 } } );
# Update all documents matching the selector or upsert
bulk->find( { a => 2 } )->upsert()->update_many( { '$inc' => { x => 2 } } );
# Replaces a single document matching the selector or upsert
bulk->find( { a => 3 } )->upsert()->replace_one( { x => 3 } );
# Remove a single document matching the selector
bulk->find( { a => 4 } )->delete_one();
# Remove all documents matching the selector
bulk->find( { a => 5 } )->delete_many();
# Remove all documents
bulk->find( {} )->delete_many();
=head1 DESCRIPTION
This class provides means to specify write operations constrained by a query
document.
To instantiate a C<MongoDB::BulkWriteView>, use the L<find|MongoDB::BulkWrite/find>
method from L<MongoDB::BulkWrite> or the L</upsert> method described below.
Except for L</upsert>, all methods have an empty return on success; an
exception will be thrown on error.
=head1 METHODS
=head2 delete_many
$bulk->delete_many;
Removes all documents matching the query document.
=head2 delete_one
$bulk->delete_one;
Removes a single document matching the query document.
=head2 replace_one
$bulk->replace_one( $doc );
Replaces the document matching the query document. The document
to replace must not have any keys that begin with a dollar sign, C<$>.
=head2 update_many
$bulk->update_many( $modification );
Updates all documents matching the query document. The modification
document must have all its keys begin with a dollar sign, C<$>.
=head2 update_one
$bulk->update_one( $modification );
Updates a single document matching the query document. The modification
document must have all its keys begin with a dollar sign, C<$>.
=head2 upsert
$bulk->upsert->replace_one( $doc );
Returns a new C<MongoDB::BulkWriteView> object that will treat every
update, update_one or replace_one operation as an upsert operation.
