Member Function Documentation

void mongocxx::options::create_collection::auto_index_id ( bool  auto_index_id)

Specify false to disable the automatic creation of an index on the _id field.

Note
For replica sets, all collections must have autoIndexId set to true.
Parameters
auto_index_idWhether or not this collection will automatically generate an index on _id.
void mongocxx::options::create_collection::capped ( bool  capped)

To create a capped collection, specify true.

Note
If you specify true, you must also set a maximum size using the size() method.
Parameters
cappedWhether or not this collection will be capped.

void mongocxx::options::create_collection::max ( int  max_documents)

The maximum number of documents allowed in the capped collection.

Note
The size limit takes precedence over this limit. If a capped collection reaches the size limit before it reaches the maximum number of documents, MongoDB removes old documents.
Parameters
max_documentsMaximum number of documents allowed in the collection (if capped)
void mongocxx::options::create_collection::no_padding ( bool  no_padding)

When true, disables the power of 2 sizes allocation for the collection.

See also
: https://docs.mongodb.org/manual/reference/method/db.createCollection/
Parameters
no_paddingWhen true, disables power of 2 sizing for this collection.
void mongocxx::options::create_collection::size ( int  max_size)

A maximum size, in bytes, for a capped collection.

Note
Once a capped collection reaches its maximum size, MongoDB removes older documents to make space for new documents.
Size is required for capped collections and ignored for other collections.
Parameters
max_sizeMaximum size, in bytes, of this collection (if capped)
void mongocxx::options::create_collection::storage_engine ( bsoncxx::document::view_or_value  storage_engine_opts)

Specify configuration to the storage on a per-collection basis.

Note
This option is currently only available with the WiredTiger storage engine.
Parameters
storage_engine_optionsConfiguration options specific to the storage engine.
bsoncxx::document::value mongocxx::options::create_collection::to_document ( ) const

Return a bson document representing the options set on this object.

Returns
Options, as a document.
void mongocxx::options::create_collection::validation_criteria ( class validation_criteria  validation)

Specify validation criteria for this collection.

Parameters
validationValidation criteria for this collection.
