# processed abstract method

List<int>? processed({

1. bool flush = true,
2. 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

    // TODO: Which stream?
    List<int>? processed({bool flush = true, bool end = false});
