Examples of com.mongodb.DBCursor.limit()

com.mongodb.DBCursor.limit()
Limits the number of elements returned. Note: parameter n should be positive, although a negative value is supported for legacy reason. Passing a negative value will call {@link DBCursor#batchSize(int)} which is the preferred method. @param n the number of elements to return @return a cursor to iterate the results @dochub limit
