SYNOPSIS

16
17           # Update all documents matching the selector
18           bulk->find( { a => 2 } )->update_many( { '$inc' => { x => 2 } } );
19
20           # Update all documents matching the selector, with respect to a collation

DESCRIPTION

55       This class provides means to specify write operations constrained by a
56       query document.
57
58       To instantiate a "MongoDB::BulkWriteView", use the find method from
59       MongoDB::BulkWrite.
60
61       Except for "arrayFilters", "collation" and "upsert", all methods have
62       an empty return on success; an exception will be thrown on error.
63

METHODS

65   arrayFilters
66           $bulk->arrayFilters( $array_filters )->update_many( $modification );
67
68       Returns a new "MongoDB::BulkWriteView" object, where the specified
69       arrayFilter will be used to determine which array elements to modify
70       for an update operation on an array field.
71
72   collation
73           $bulk->collation( $collation )->delete_one;
74
75       Returns a new "MongoDB::BulkWriteView" object, where the specified
76       collation will be used to determine which documents match the query
77       document.  A collation can be specified for any deletion, replacement,
78       or update.
79
80   delete_many
81           $bulk->delete_many;
82
83       Removes all documents matching the query document.
84
85   delete_one
86           $bulk->delete_one;
87
88       Removes a single document matching the query document.
89
90   replace_one
91           $bulk->replace_one( $doc );
92
93       Replaces the document matching the query document.  The document to
94       replace must not have any keys that begin with a dollar sign, "$".
95
96   update_many
97           $bulk->update_many( $modification );
98
99       Updates all documents  matching the query document.  The modification
100       document must have all its keys begin with a dollar sign, "$".
101
102   update_one
103           $bulk->update_one( $modification );
104
105       Updates a single document matching the query document.  The
106       modification document must have all its keys begin with a dollar sign,
107       "$".
108
109   upsert
110           $bulk->upsert->replace_one( $doc );
111
112       Returns a new "MongoDB::BulkWriteView" object that will treat every
113       update, update_one or replace_one operation as an upsert operation.
