Examples of findAndModify()

com.mongodb.DBCollection.findAndModify()
Finds the first document in the query and updates it. @param query query to match @param fields fields to be returned @param sort sort to apply before picking first document @param remove if true, document found will be removed @param update update to apply @param returnNew if true, the updated document is returned, otherwise the old document is returned (or it would be lost forever) @param upsert do upsert (insert if document not present) @return the document
