Examples of com.mongodb.DBCollection.find()

com.mongodb.DBCollection.find()
Calls {@link DBCollection#find(com.mongodb.DBObject,com.mongodb.DBObject,int,int)} and applies the query options @param query query used to search @param fields the fields of matching objects to return @param numToSkip number of objects to skip @param batchSize the batch size. This option has a complex behavior, see {@link DBCursor#batchSize(int) } @param options - see Bytes QUERYOPTION_ @return the cursor @throws MongoException @dochub find
