# processed method

List<int> processed ({bool flush: true, bool end: false })

Get a chunk of processed data. When there are no more data available, processed will return `null`. Set `flush` to `false` for non-final calls to improve performance of some filters.

The last call to processed should have `end` set to `true`. This will make sure an 'end' packet is written on the stream.

## Implementation

    List<int> processed({bool flush: true, bool end: false});
