filter()

const bsoncxx::document::view_or_value& mongocxx::v_noabi::model::replace_one::filter

(

)

const

Gets the filter for replacement.

The filter to be used for the replacement operation.

hint() [2/2]

replace_one& mongocxx::v_noabi::model::replace_one::hint

(

class hint

index_hint

)

Sets the index to use for this operation.

Note

if the server already has a cached shape for this query, it may ignore a hint.

Parameters

index_hint

Object representing the index to use.

Returns

A reference to the object on which this member function is being called. This facilitates method chaining.

replacement()

const bsoncxx::document::view_or_value& mongocxx::v_noabi::model::replace_one::replacement

(

)

const

Gets the replacement document.

Returns

The document that will replace the original selected document.

upsert() [1/2]

const stdx::optional<bool>& mongocxx::v_noabi::model::replace_one::upsert

(

)

const

Gets the current value of the upsert option.

Returns

The optional value of the upsert option.

upsert() [2/2]

replace_one& mongocxx::v_noabi::model::replace_one::upsert

(

bool

upsert

)

Sets the upsert option.

When upsert is true, this operation will insert the replacement document as a new document if no existing documents match the filter. When upsert is false, the replacement operation does nothing if there are no matching documents. By default, upsert is false.

Parameters

upsert

If set to true, creates a new document when no document matches the query criteria. The server side default is false, which does not insert a new document if a match is not found.
