count()

int TMongoQuery::count

(

const QVariantMap &

criteria = QVariantMap()

)

find()

bool TMongoQuery::find	(	const QVariantMap &	criteria = QVariantMap(),
		const QVariantMap &	orderBy = QVariantMap(),
		const QStringList &	fields = QStringList()
	)

Finds documents by the criteria criteria in the collection and returns the number of the documents.

Use the fields parameter to control the fields to return.

		const QStringList &	fields = QStringList()
	)

findOne()

QVariantMap TMongoQuery::findOne	(	const QVariantMap &	criteria = QVariantMap(),
		const QStringList &	fields = QStringList()

Finds documents by the criteria criteria in the collection and returns a retrieved document as a QVariantMap object.

Use the fields parameter to control the fields to return.

insert()

bool TMongoQuery::insert

(

QVariantMap &

document

)

Inserts the document document into the collection.

lastErrorString()

QString TMongoQuery::lastErrorString

)

const

Returns the number of documents affected by the result's Mongo statement, or -1 if it cannot be determined.

inline

operator=()

TMongoQuery & TMongoQuery::operator=

const TMongoQuery &

other

)

Assignment operator.

remove()

int TMongoQuery::remove

(

const QVariantMap &

criteria

)

Removes documents that matches the criteria from the collection.

removeById()

bool TMongoQuery::removeById

(

const QVariantMap &

document

)

Removes an existing document that matches the ObjectID of the document from the collection.

setLimit()

void TMongoQuery::setLimit ( int  limit )

When the upsert is true, inserts the document in the collection if no document matches the criteria.

updateById()

bool TMongoQuery::updateById

(

const QVariantMap &

document

)

Updates an existing document that matches the ObjectID with the document.

updateMany()

int TMongoQuery::updateMany	(	const QVariantMap &	criteria,
		const QVariantMap &	document
	)

Updates existing documents of the selection criteria criteria in the collection with new document document.

updateMulti()

int TMongoQuery::updateMulti ( const QVariantMap &  criteria, const QVariantMap &  document  )

inline

value()

QVariantMap TMongoQuery::value

(
